1 - 50 T / H Dolomite Vertical Mill - Vertical Roller Mill Equipment In Non-Metallic Ores Plant
Description
How to effectively increase the production of dolomite vertical mills?
1. Control the particle size and moisture of the raw materials entering the vertical mill. In principle, the smaller the particle size and moisture, the more conducive it is to increasing production.
2. A reasonable range of inlet and outlet pressure differences should be set.
3. Strictly control the air leakage status of the raw material system. If the air leakage is large, it is difficult to increase the production capacity.
4. Timely check the wear status. If the grinding roller is worn, it is necessary to adjust the material retaining ring in a timely manner. Only by doing proper maintenance and upkeep can production be truly increased.
5. Regular maintenance and upkeep are indispensable. To increase production capacity, it is necessary to take good care of the machinery and equipment in daily life, use the machines reasonably according to normal operating procedures, and learn maintenance and skills thoroughly. Strengthen maintenance and upkeep in daily life to quickly improve the equipment's operating rate and production capacity.
HVM vertical grinding machine is an advanced grinding equipment designed and developed through extensive absorption of advanced technology from various vertical grinding machines both domestically and internationally, as well as drawing on a large amount of engineering application experience. It is safe, environmentally friendly, energy-saving, and efficient, and integrates drying, grinding, powder selection, and conveying functions. The main performance and economic and technical indicators of the equipment have reached the international advanced level.
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 moisture are dried during contact with hot gases to achieve the required product moisture.
