High Efficiency Calcite Vertical Mill Vertical Roller Mill for Calcite Grinding - 325-2500 Mesh
Description

Calcite Vertical Roller Mill is a vertical roller mill specifically designed for processing calcite, a natural calcium carbonate mineral. Through rolling, grinding, and grading techniques, calcite raw materials are crushed into powders of different fineness (usually 325-3000 mesh), which are widely used in industries such as coatings, plastics, papermaking, and building materials. The following are its core points:
1. Working principle
Rolling and grinding: Calcite raw materials are crushed by the squeezing and shearing forces between the grinding disc and the grinding roller.
Wind classification: The ground powder is transported by airflow to the classifier, separated by fineness, and the coarse powder is returned for regrinding.
Powder collection and dust removal: The finished powder is discharged through a cyclone collector and dust collector, which meets environmental protection requirements.

2. Core advantages
High fineness: It can produce ultrafine powder with a mesh size of 325-3000 (D97 ≤ 5 µ m), meeting the needs of high-end industries such as coatings and pharmaceuticals.
Energy saving and efficient: 30-50% more energy-efficient than traditional ball mills, with a production capacity of 1-100 tons/hour.
Environmentally friendly and low-noise: fully enclosed system, equipped with pulse dust collector, dust emission ≤ 20mg/m ³.
Automation control: The PLC system adjusts parameters in real-time, such as grinding roller pressure and classifier speed.

Re:The data based on Mohs'hardness 3-4 material
The product fineness can reach 10 um(1250 mesh)

Advantages of calcite vertical mill:
1. Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption, compared to ball mills, the energy consumption is 40% -50% lower;
(2) Large single machine production capacity, capable of utilizing low valley electricity;
(3) Vertical grinding technology and equipment are vigorously advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitive strength of enterprises in the powder industry in this region and even across the country;
2. Easy maintenance and low operating costs:
(1) The grinding roller can be turned out of the machine using a hydraulic device, and the replacement of the roller sleeve lining plate and the maintenance space of the mill are large, making the maintenance operation very convenient;
(2) The grinding roller sleeve can be used upside down, extending the service life of wear-resistant materials;
(3) Before starting the machine, there is no need to apply fabric to the grinding disc, and the mill can be started without load, eliminating the difficulty of starting the machine;
(4) Low wear, special materials are used for the grinding roller and disc lining plate, resulting in a long service life;
(5) High degree of automation: The automatic control technology adopts the Siemens series PLC from Germany, equipped with an automatic control system, which can achieve remote control and easy operation. The workshop can basically achieve unmanned operation, saving operating costs;
3. Low comprehensive investment cost:
Integrating crushing, drying, grinding, and conveying, the process flow is simple, the system equipment is few, the structural layout is compact, and the floor area is only 50% of that of the ball mill. It can be arranged outdoors, with low construction costs, directly reducing the investment cost of the enterprise.
4. Stable product quality:
(1) The material stays in the grinder for a short time, making it easy to detect the particle size distribution and composition of the product, and ensuring stable product quality;
(2) The product has uniform particle morphology, narrow particle size distribution, good flowability, and strong product adaptability.
5. High reliability
(1) Adopting a grinding roller limit device to avoid severe vibration caused by material breakage during the working time of the mill;
(2) Adopting a new type of roller sealing device, the sealing is more reliable, and there is no need for a sealing fan, further reducing the oxygen content in the mill and achieving better explosion suppression performance.
6. Environmental protection:
(1) The entire system of HVM vertical grinding machine has low vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and there is no dust leakage, basically achieving a dust-free workshop.
