Energy-saving Coal Mill Vertical Roller Grinding Mill For Coal Industrial Power Plant
Product Introduction
Hefei Hengcheng is a national high-tech enterprise, a small and medium-sized technology-based enterprise specializing in the R&D, manufacturing, sales and service of powder industrial technology and equipment. The company has passed the ISO9001 international quality system certification, and is committed to providing domestic and foreign customers with a full range of solutions in the field of powder engineering covering equipment manufacturing and complete equipment, engineering design, general contracting, and technical services and consulting.
HVM vertical mill is a kind of advanced grinding equipment which is safe, environmentally friendly, energy-saving and efficient, and integrates drying, grinding, powder selection and transportation functions, based on extensive absorption of advanced technologies of various vertical mills at home and abroad and reference to a large number of engineering application experiences. The main performance and economic and technical indicators of the equipment have reached the international advanced level.
【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.

Equipment advantages
1. Large production capacity, low energy consumption, and environmental protection.
2. The roll sleeve of the vertical coal mill can be turned over for use, which is not only conducive to improving the output of the coal mill, but also can reduce wear and prolong its service life.
3. Install explosion-proof devices to ensure safe production. The upper shell is equipped with an explosion-proof valve to prevent the explosion of pulverized coal in the mill and ensure the safe use of the equipment.
4. The foot disc shaped grinding plate and tyre shaped roller sleeve adopted by the vertical coal mill are more suitable for coal grinding.
5. The roller bearing does not require special sealing. The grinding roller device adopts a pair of self-aligning roller bearings, and the bearing sealing chamber extends outside the casing, without contacting with dust containing gas. Therefore, simple sealing can prevent the grinding roller bearing from entering dust, and no sealing fan is required.
6. The transmission part of the vertical pulverizer does not need an auxiliary transmission device.
7. The slag removal part is simple. The coal vertical mill has less slag discharge, and the slag discharge port is equipped with a cover plate, so it is unnecessary to install a slag discharge valve.
