Hefei Hengcheng, a professional supplier and service provider of complete milling solutions for powder processing in China, is dedicated to the development, design, manufacturing and sales of various powder equipment and complete milling production lines. With decades of production experience, it has a strong production base, rich manufacturing experience, a research and development center with excellent instruments, a fully equipped trial grinding center, and a good, hard working and enterprising elite team, After decades of quality accumulation, Guilin Hongcheng has gradually formed a complete set of R&D, production, sales and service systems. In the process of innovation and development, it has gradually produced a series of Raymond mill, slag vertical mill, ultra-fine mill, ultra-fine vertical mill and other advanced equipment. Its products and services are all over Asia, Africa, Europe, the United States and other countries and regions. It is an ideal grinding equipment manufacturer and supplier.
【Working Principle】: the motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed port, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, materials move towards the edge of the grinding plate. When passing through the circular groove on the grinding plate, they are crushed by the grinding roller. The crushed materials are carried away at the edge of the grinding plate by the high-speed airflow at the wind ring. Large particles directly fall onto the grinding plate for re grinding. When the materials in the airflow pass through the dynamic and static separators, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding. The qualified fine powder is grinded together with the airflow, The product is collected in the powder collecting device. Materials containing water are dried in the process of contacting with hot gas to reach the required product moisture.

Cement raw meal vertical mill
● High grinding efficiency.
The advanced material layer grinding principle is adopted to save 40~50% of the power consumption of the system compared with the ball mill. With the increase of raw material moisture, the power saving effect is more significant;
● Large drying capacity.
The kiln hot air waste gas can be used to dry the materials, and the water content in the raw meal mill can reach 15.
● The equipment occupies a small area and the process flow is simple.
HVM vertical mill integrates fine crushing, drying, grinding, powder selection, and transportation, without additional drying, powder selection, lifting and other equipment. The workshop area only accounts for 70% of the ball mill system, and the space only accounts for 50~60%;
● Low noise, less dust and clean operating environment.
The grinding roller and grinding disc do not contact directly during operation, and there is no metal impact. The noise is 20~25 decibels lower than that of the ball mill. The system adopts fully sealed negative pressure operation, without dust, and the production environment is clean;
● Low wear, little metal pollution of products, and metal wear is only 5-10g/t.
● The grinding roll sleeve can be turned over for use, which is conducive to extending the service life and reducing the production cost. Easy operation and maintenance;
● The chemical composition of the grinding product is stable, and the particle grading is uniform, which is conducive to calcination.
