In the complex chain of modern industrial production, the material transportation link is like a "blood vessel" that maintains the smooth operation of the entire production process. In recent years, Pneumatic conveying system has gradually replaced traditional mechanical conveying methods due to their significant advantages of high efficiency, environmental friendliness, and flexibility, becoming the core transportation solution in various fields such as chemical engineering, food, medicine, and electricity. Technical core: Efficient transmission logic with air as the "carrier"The core principle of pneumatic conveying system is to use the energy of compressed air or gas to push bulk materials (such as powders, particles, fibers, etc.) in a closed pipeline to achieve directional movement. Compared with traditional methods such as belt conveyor and spiral conveyor, its technological advantages are reflected in three aspects:Firstly, there is spatial adaptability. The powder conveying system can flexibly design pipeline routes according to the layout of the factory, and can achieve vertical, horizontal, or curved paths, especially suitable for complex workshops or high-altitude work scenarios. After the introduction of this system in a large fertilizer plant, the transportation distance of raw materials was reduced by 40% through a three-dimensional pipeline network, and the utilization rate of the plant was increased by 25%. ​Next is material protection. Sealed pipelines can effectively prevent materials from getting damp, contaminated, or volatile, which is crucial for sterile raw materials in the pharmaceutical industry and powder additives in the food industry. According to data from the China Medical Equipment Association, pharmaceutical companies that use pneumatic conveying can control material loss rates below 0.5%, which is much lower than the traditional method of 3% -5%. ​Finally, cleanliness and safety. The absence of mechanical friction contact reduces dust leakage, not only lowering the risk of occupational diseases, but also avoiding safety hazards of flammable and explosive materials. In the production of lithium battery materials, pneumatic conveying has become a mandatory standard in the industry, and its anti-static design can reduce the risk of dust explosion to less than one in ten thousand. Market dynamics: policy driven and technology iterative dual wheel effortsIn recent years, the pneumatic conveying system market has shown a double-digit growth trend. According to the White Paper on China's Industrial Automation Market, the market size will reach 12.76 billion yuan in 2024, a year-on-year increase of 14.3%, and is expected to exceed 20 billion yuan in 2027. Behind this growth is a dual driving force:At the policy level, the "dual carbon" target has forced industrial enterprises to upgrade their environmental protection equipment. The air conveying system has become the preferred solution for emission reduction and renovation in heavy polluting industries such as steel and cement due to its dust emissions being only 1/20 of traditional methods. A certain steel group successfully passed environmental protection inspection by transforming the material conveying system of the entire plant, reducing dust emissions by 3200 tons annually. ​In terms of technological iteration, intelligent upgrading has become a key breakthrough. The new generation system equipped with IoT sensors can monitor pipeline pressure, material flow rate, and equipment status in real time, and automatically adjust conveying parameters through AI algorithms. The intelligent control system developed by a certain automation enterprise has reduced equipment failure rate by 35% and maintenance costs by 28%. Industry Penetration: A Cross-Sector Application Map from Chemicals to Food The application landscape of pneumatic conveying systems is expanding at a remarkable pace, demonstrating differentiated technical adaptability across industries:   - Chemical Industry – The earliest large-scale adopter. For corrosive materials like PVC resin and dye intermediates, wear-resistant alloy pipelines and inert gas conveying solutions are employed. One chemical park achieved a 60% increase in material handling efficiency and annual energy savings exceeding 8 million RMB through a clustered pneumatic conveying network.   - Food & Pharmaceutical Sectors – Highlighting hygiene advantages. Stainless steel mirror-finished pipelines combined with CIP (Clean-in-Place) systems meet GMP certification requirements. A leading dairy company used this system to transport whey protein powder, reducing microbial contamination by **99%** and boosting product qualification rates to **99.8%**.   - New Energy Industry – Surging demand drives specialized solutions. For lithium battery cathode materials (e.g., ternary precursors), pneumatic conveying must ensure "zero iron ion contamination." The adoption of ceramic-lined pipelines maintains material purity above 99.99%, contributing to a 5%-8% increase in power battery energy density. Future Trends: Parallel Advancements in Green Technology and Customization Industry experts highlight two key development directions for pneumatic conveying systems: deep decarbonization and highly customized solutions.   - Green Technology: Renewable energy integration is the core pathway. Innovations such as solar-powered air compressors and biodegradable pipeline materials are driving the evolution toward "zero-carbon conveying." One environmental tech company's solar-powered pneumatic system achieved energy self-sufficiency in an agricultural waste processing project, reducing carbon emissions by 300 tons annually.  - Customization: Tailored solutions are emerging for niche applications. For instance, vacuum-based micro-conveying systems now enable micron-level precision in transporting metal powders for 3D printing. Meanwhile, in construction waste recycling, high-pressure, large-diameter systems can handle concrete particles exceeding 50mm, boosting resource recovery rates above 90%.   With the acceleration of Industry 4.0, pneumatic conveying systems Dense phase conveying / Dilute phase conveying are evolving from simple transport tools into "intelligent material management platforms." Their seamless integration with MES (Manufacturing Execution Systems) enables end-to-end traceability—from raw material intake to finished product delivery—providing critical data support for smart manufacturing.   In this transformation of industrial material handling, those who master core technologies and scenario-specific solutions first will dominate the future of industrial logistics.

Introduction Limestone As an extremely important industrial raw material, is widely used in numerous industries such as cement, steel, chemicals, and electric power. In these applications, limestone usually needs to be ground to a specific fineness to meet the requirements of different production processes. The selection of grinding equipment plays a decisive role in the efficiency, cost, and product quality of limestone processing. Vertical mills, as advanced grinding equipment, have been increasingly widely used in the limestone grinding industry in recent years, with their market demand showing a continuous growth trend. Current Status of the Limestone Grinding Industry Industry Scale and Development Trends With the continuous advancement of global infrastructure construction and the sustained development of industrial production, the demand for limestone-related products has steadily increased, driving the continuous expansion of the limestone grinding industry. According to data from market research institutions, the global limestone grinding market has grown at an annual rate of 20% in the past few years. In some emerging economies, such as China and India, due to large-scale urbanization and industrialization, the growth rate of the limestone grinding industry is even more significant. It is expected that in the next few years, with increasingly stringent environmental protection requirements and emphasis on comprehensive resource utilization, the limestone grinding industry will further develop towards large-scale, intensive, and green-oriented directions. Requirements for Limestone Powder in Different Application Fields Different application fields have varying requirements for indicators such as particle size, purity, and whiteness of limestone powder. In cement production, limestone powder, as one of the main raw materials, generally requires a particle size between 80μm-200μm to ensure the burnability of cement raw meal and clinker quality. In the steel industry, limestone powder used for desulfurization usually requires a finer particle size, generally below 45μm, to improve desulfurization efficiency. In the chemical industry, such as in the production of calcium carbonate and light calcium carbonate, higher requirements are placed on the purity and whiteness of limestone powder, and the particle size distribution also needs to meet specific process conditions. In the electric power industry, limestone powder is used for flue gas desulfurization, requiring a particle size of 325 mesh (45μm) or even finer to ensure sufficient reaction with sulfur dioxide and achieve efficient desulfurization. Challenges Faced by Traditional Grinding Equipment Before the widespread application of vertical mills, limestone grinding mainly used traditional grinding equipment such as ball mills and Raymond mills. Although ball mills have strong adaptability to materials, they have problems such as high energy consumption, low grinding efficiency, large floor space, and complex equipment maintenance. For example, the power consumption of ball mills for grinding limestone is usually between 30kWh/t-50kWh/t, and due to the wear of the grinding medium (steel balls), the equipment maintenance cost is high. Raymond mills, although overcoming some shortcomings of ball mills to a certain extent, have relatively small output and limited product fineness adjustment range, making it difficult to meet the needs of large-scale, high-fineness limestone grinding. With the development of the industry and intensified market competition, traditional grinding equipment gradually struggle to meet the requirements of high efficiency, energy saving, and environmental protection in the limestone grinding industry, which provides a broad market space for the development of vertical mills. Working Principle and Advantages of Vertical Mills Working Principle Vertical mills are mainly composed of a grinding disc, grinding rollers, a classifier, a transmission device, and a shell. Their working principle is as follows: the motor drives the grinding disc to rotate through a reducer; the material to be ground is fed into the center of the grinding disc by a feeding device; under the action of centrifugal force, the material moves to the edge of the grinding disc and enters the grinding area between the grinding rollers and the grinding disc. The material is crushed under the pressure of the grinding rollers and the friction of the grinding disc. At the same time, hot air introduced from the bottom of the mill dries the moisture in the material and blows up the ground material, making it rise with the air flow. When the rising material passes through the classifier, qualified fine powder is selected under the action of the classifier, enters the dust collection device with the air flow, and is collected as finished products; unqualified coarse powder falls back to the grinding disc for re-grinding.   Performance Advantages  - **High Efficiency and Energy Saving**: Vertical mills adopt the principle of material layer grinding. The material forms a material layer between the grinding rollers and the grinding disc, and is crushed by the pressure of the grinding rollers. Compared with the point contact grinding method of ball mills, the energy utilization rate is higher. According to statistics, the power consumption of vertical mills for grinding limestone is 30%-50% lower than that of ball mills, which can effectively reduce production costs. For example, in a cement clinker production line with a daily output of 5,000 tons, using a vertical mill to grind limestone, the power consumption per ton is only about 18kWh, while using a ball mill, the power consumption per ton is as high as 35kWh or more. - **Good Product Quality**: Vertical mills are equipped with high-efficiency classifiers, which can accurately control the particle size distribution of products. The produced limestone powder has uniform particle size and regular particle shape, which is conducive to improving the quality of downstream products. At the same time, due to the low pollution to materials during the grinding process of vertical mills, the purity of limestone can be well maintained, meeting the needs of some industries with high requirements for product quality. - **Strong Drying Capacity**: Vertical mills can use hot air to dry materials and can handle limestone raw materials with high moisture content. Under normal circumstances, vertical mills can dry materials with an inlet moisture content of up to 15%, and in some specially designed vertical mills, they can even handle materials with higher moisture content. This advantage makes vertical mills have obvious competitiveness in humid areas or when processing limestone mine resources with high water content. - **Simple System and Small Floor Space**: Vertical mills integrate crushing, grinding, drying, classifying, and conveying, with a simple process flow and few system equipment. Compared with traditional grinding systems, they can save a lot of equipment investment and civil engineering costs. Moreover, vertical mills have a compact structure, and their floor space is only about 50% of that of ball mill systems, which can effectively save production sites. - **Reliable Operation and Convenient Maintenance**: The grinding rollers and grinding discs of vertical mills are made of special wear-resistant materials, with a long service life. At the same time, the grinding rollers adopt a reversible structure, which can be turned out of the machine body during maintenance, facilitating the replacement of grinding roller liners and the maintenance of other components, greatly reducing the downtime of the equipment, and improving the operational reliability and maintenance convenience of the equipment. Demand Analysis for Vertical Mills in the Limestone Grinding Industry Demand Characteristics of Different Application Fields - **Cement Industry**:  The cement industry is the largest consumer of limestone, and its demand for vertical mills is mainly reflected in large-scale production and stable product quality.

Moreover, the high efficiency and energy-saving characteristics of vertical mills can reduce the production costs of power enterprises. In large-scale thermal power projects, using vertical mills to prepare limestone powder has significant economic and environmental benefits. For example, a thermal power plant with an installed capacity of 1 million kilowatts can save millions of yuan in electricity fees every year by using vertical mills to prepare limestone powder for desulfurization. - **Chemical Industry**: The chemical industry has diverse demands for limestone powder, and different chemical products have different requirements for the particle size, purity, and whiteness of limestone powder. Through flexible process adjustment and precise classification control, vertical mills can produce limestone powder products that meet various chemical needs. For example, in the production of light calcium carbonate, high-purity, fine-grained, and uniformly distributed limestone powder is required as a raw material, and vertical mills can well meet these requirements, providing a guarantee for the quality of chemical products. At the same time, the chemical industry usually has high requirements for the continuity and stability of the production process, and the reliable operation and convenient maintenance of vertical mills also make them highly adaptable in the chemical industry. - **Steel Industry (Desulfurization)**: In the steel industry, limestone powder is used for desulfurization during smelting to reduce the sulfur content in steel and improve steel quality. Similar to the electric power industry, the steel industry also requires fine particle size of limestone powder for desulfurization, generally below 45μm. Vertical mills can efficiently produce fine-grained limestone powder that meets the requirements, and their large capacity characteristics can meet the large-scale production needs of steel enterprises. In addition, steel enterprises usually pay attention to production efficiency and cost control, and the energy-saving advantage of vertical mills helps reduce the production costs of steel enterprises and improve their competitiveness.

In recent years, the accelerated green transformation of traditional industries such as building materials, electric power, and metallurgy, coupled with the growing demand for efficient grinding equipment in new energy and new materials sectors, has significantly boosted the market attention and application scope of vertical roller mills (VRM). As an efficient grinding solution integrating crushing, grinding, drying, and classifying functions, VRMs are witnessing expanded adoption. From industry data to technological innovations, and from policy guidance to corporate strategies, vertical roller mills are embracing new development opportunities while simultaneously facing dual challenges of technological upgrading and market competition. This makes an in-depth analysis of their industry landscape and development trends particularly crucial. Market demand continues to climb, with multi-sector drivers serving as the core engine According to recent industry research reports, the global vertical roller mill market reached a scale exceeding RMB 8 billion in 2024, representing a year-on-year growth of approximately 12%. The Chinese market contributed over 60% of this share, establishing itself as the core engine driving the global development of the vertical roller mill industry. This growth trajectory is underpinned by synergistic demand drivers across multiple sectors. In the building materials industry, the green transformation of cement production has been a key catalyst. Traditional ball mills are characterized by high energy consumption and significant dust emissions, whereas vertical roller mills consume only 60%-70% of the energy required by ball mills and can maintain dust emission concentrations below 10mg/m³. This performance fully aligns with environmental requirements under China's "Dual Carbon" policy goals. In the new energy sector, the production of lithium battery cathode materials (such as lithium iron phosphate and ternary materials) imposes extremely high requirements on the fineness and uniformity of raw materials. Owing to their precise classification capability and consistent grinding performance, vertical roller mills have become the preferred grinding equipment in this field. With the continuous growth in global sales of new energy vehicles and the accelerated expansion of cathode material production capacity, the demand for vertical roller mills in China's new energy industry increased by over 30% year-on-year in 2024. Some equipment manufacturers have even reported order backlogs extending to the second half of 2025. Furthermore, in the field of solid waste treatment, vertical roller mills demonstrate unique advantages in the resource utilization of industrial solid wastes such as steel slag, mineral slag, and fly ash. Taking steel slag as an example, the steel slag micropowder produced by vertical roller mills can be used as a substitute for cement admixtures. This not only reduces pollution from solid waste storage but also decreases the energy consumption associated with cement production. Currently, more than 50 industrial solid waste resource utilization projects in China have adopted vertical roller mill equipment, contributing significantly to the advancement of the "Zero-Waste City" initiative.   Technical innovation is accelerating, with intelligence and customization becoming mainstream trends Faced with diverse demands from different industries, vertical roller mill manufacturers are increasing R&D investments to shift from "general-purpose" to "customized" and "intelligent" technologies. A series of technological breakthroughs are reshaping the competitive landscape of the industry. In terms of core technological upgrades, material improvements for grinding components have become a key focus. Traditional vertical roller mills typically use standard wear-resistant cast iron for grinding rollers and plates, with a service life of only 3,000–5,000 hours. In contrast, grinding components made from high-chromium alloys and ceramic composites can extend service life to 8,000–12,000 hours while reducing the incorporation of metal impurities during the grinding process. This meets the stringent purity requirements of new energy materials. For example, the "ceramic composite grinding rollers" developed by one equipment manufacturer have been adopted by several lithium battery material producers, increasing product qualification rates by 5%–8%. In the field of intelligent upgrades, the integration of IoT and big data technologies has enabled "unmanned" operation of vertical roller mills. By installing sensors for vibration, temperature, and current on the equipment, operational data is collected in real time and uploaded to a cloud-based management platform. The system automatically analyzes equipment status and provides early warnings for potential failures. For instance, when roller wear reaches a critical level, the platform automatically sends a replacement alert and coordinates with the spare parts management system to reduce downtime. Currently, the penetration rate of intelligent equipment among leading Chinese vertical roller mill manufacturers exceeds 40%, with some production lines achieving 24-hour continuous fault-free operation. Regarding customized solutions, companies are designing specialized equipment tailored to the characteristics of different materials. Taking graphite powder grinding as an example, traditional vertical roller mills often face issues like "material sticking" and "blockages" due to graphite’s flexibility and viscosity. One manufacturer developed a customized vertical mill featuring "low-temperature grinding + negative pressure classification." By controlling the grinding temperature below 50°C and incorporating a specially designed classification impeller, the system effectively addresses challenges in graphite powder processing. This equipment has already been deployed in several anode material production plants in China, with positive market feedback.

Recent technological breakthroughs in bentonite grinding have injected new momentum into the efficient utilization of this versatile non-metallic mineral, often hailed as the "clay of a thousand uses." As industries increasingly demand higher quality and finer bentonite powder, the development and application of advanced grinding technologies have become a key industry focus. Bentonite, with montmorillonite as its main mineral component, possesses excellent properties such as adsorbability, ion exchangeability, and cementation. It is widely used in various fields including foundry, drilling mud, environmental protection, agriculture, and building materials. In the foundry industry, bentonite acts as a binder and plays a key role in the performance of molding sand. In the field of environmental protection, its strong adsorption capacity makes it an ideal material for sewage treatment and soil remediation. In agriculture, bentonite can be used as a soil conditioner and pesticide additive, helping to improve crop yield and quality. However, different application scenarios have significantly different requirements for the fineness of bentonite powder. Ranging from less than 200 meshes for feed additives to more than 325 meshes for chemical additives and the papermaking industry, precise grinding has become a core link to meet market demands. To address this challenge, many equipment manufacturing enterprises have actively engaged in technological innovation. For instance, the HVM series large-scale ultra-fine vertical mills and high-efficiency pulverizers launched by Hefei Hengcheng, through the iteration of classification technology and process upgrading, have not only significantly improved the production efficiency of bentonite but also ensured the stability of powder quality. These devices can grind bentonite to specific fineness according to different needs, and the produced powder features high whiteness, high purity, and good dispersibility, which has greatly expanded the application potential of bentonite in the high-end market.   Meanwhile, intelligent technologies have gradually been integrated into bentonite grinding production lines. Through the PLC automatic control system, the entire process from raw material feeding to product powder output has been automated and fully enclosed. This not only improves production efficiency but also reduces labor costs and dust pollution, conforming to the current industrial development trend of green environmental protection. Take a large-scale bentonite processing enterprise as an example. After adopting intelligent grinding equipment, its product qualification rate has increased from 92% to 99.5%, and its production capacity has also been significantly improved.   With the continuous advancement of technology, bentonite grinding is developing towards higher efficiency, intelligence, and greener practices. This will not only promote the transformation and upgrading of the bentonite industry itself but also provide higher-quality and more diversified products for mandownstream industries. It will further tap the "versatile" value of bentonite and help related industries achieve high-quality development.

The working principle of a positive pressure dense phase pneumatic conveying system: Dense coherent ash conveying is based on the pneumatic conveying principle of solid gas two-phase flow, utilizing the static and dynamic pressure of compressed air to transport materials with high concentration and efficiency. Fly ash must be fully fluidized in the bin pump and transported while fluidized. The entire system consists of five parts: gas source, conveying, pipeline, ash storage, and control. The conveying part is composed of conveyors (bin pumps) of corresponding specifications according to the requirements of ash conveying capacity. Each conveyor is an independent unit that can operate either as a single machine or as a system composed of multiple units. Bin pump It is the core part of the system, through which dry ash and compressed air are fully mixed and fluidized, enabling smooth operation in the system. It is a closed steel tank, equipped with supporting equipment such as inlet and outlet valves, fluidization plates, level gauges, safety valves, etc. Working principle of warehouse pump: The warehouse pump is a pressure vessel with an air nozzle, which has the characteristics of long ash conveying distance, reliable operation, high degree of automation, and requires compressed air with relatively high pressure as the conveying medium. It should be equipped with a set of air compressors. Its working process is to first open the exhaust valve and feed valve for loading, then close the feed valve and exhaust valve when the material is full, open the cylinder pressurization valve, and compress the air to take away the dust inside the cylinder. In such a cyclic manner, dust can be transported out. 1. Feeding stage: The feeding valve is in an open state, and the primary inlet and outlet valves are closed. The upper part of the bin pump is connected to the ash hopper. The fly ash collected by the dust collector freely falls into the bin pump by gravity or through the discharge machine. When the ash level is high enough to send a full signal from the material level gauge, or according to the system feeding setting time, the feeding valve is closed, the exhaust valve is closed, and the feeding state ends. 2. Pressurized fluidization stage: After the feeding stage is completed, the system automatically opens the inlet valve once. The processed compressed air enters the fluidization cone at the bottom of the bin pump through the flow control valve, and passes through the fluidization cone to evenly surround each fly ash particle. At the same time, the pressure inside the bin pump increases. When the pressure reaches the point where the pressure sensor sends a signal, the system automatically opens the discharge valve, and the pressurized fluidization stage ends. 3. Transportation stage: The discharge valve and secondary inlet valve are opened, while the primary inlet valve is not stopped. At this time, the bin pump continues to intake air, and the mixture of gas and ash enters the ash conveying pipe through the discharge valve. The fly ash is always in the fluidized state and enters the conveying pipeline for transportation. After the fly ash in the bin pump is transported, the pipeline pressure decreases, and the pressure inside the bin pump decreases. When the pressure sensor sends a signal, the secondary inlet valve is closed. When the pressure inside the bin pump continues to decrease, When the pressure sensor sends a signal, the conveying phase ends, and the inlet and outlet valves remain open, entering the blowing phase. 4. Purging stage: The inlet and outlet valves are kept open, compressed air is used to purge the bin pump and ash conveying pipeline. After a certain period of time, the purging is completed, and the inlet valve is closed. When the pressure inside the bin pump drops to normal pressure, the outlet valve is closed, and the inlet and exhaust valves are opened to enter the feeding stage. At this point, the system completes one conveying cycle and automatically enters the next conveying cycle.
