Product Introduction

Hefei Hengcheng is a technology-based enterprise that provides a complete set of solutions in the field of powder engineering, covering equipment manufacturing and equipment sets, engineering design, engineering general contracting, and technical services and consulting. With years of production experience, a strong production base, rich manufacturing experience, well-equipped research and development centers, fully equipped trial grinding centers, and a good, hardworking, and hardworking elite team, Hefei Hengcheng has gradually formed a complete set of research and development, production, sales, and service systems after decades of quality accumulation. Through innovative development, it has gradually produced a series of Raymond grinding machines, slag vertical mills We are an ideal manufacturer and supplier of grinding equipment, equipped with advanced equipment such as ultra-fine grinding machines and ultra-fine vertical grinding machines, with products and services spread throughout countries and regions such as Asia, Africa, Europe, and the United States.

Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Technical DATA

Product advantages

1. Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption
(2) Large single machine production capacity, capable of utilizing low valley electricity;

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: Automatic control technology, easy to operate, the workshop can basically achieve unmanned operation, saving operating costs;

3. 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.

4. 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.

5. Stable product quality:
(1) The material stays in the mill for a short time, which makes it easy to detect the particle size distribution and composition of the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity and strong adaptability.

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.
