Wear-resistant Roller Sleeve High Output Raw Vertical Mill Vertical Milling Machine
【Product Description】
The raw material mill is widely used for grinding (drying and grinding) cement raw materials and other materials in the building materials, metallurgy, electric power and chemical industries.
【Application】
Iron ore, copper ore, gold ore, manganese ore, cobalt ore, lead-zinc ore, bauxite, rare earth ore
HVM series raw material vertical mill is a modern grinding equipment designed and developed by our company on the basis of extensive use of modern research and development technology at home and abroad, combined with years of experience in the production of various mills. This machine integrates crushing, drying, grinding, classification and conveying, and is an ideal equipment for the grinding industry.
【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. 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 on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

【Technical Advantages】
1. The raw material vertical mill has high grinding efficiency
The raw material vertical mill can increase the grinding force by means of hydraulic pressurization, thereby increasing the output and improving the grinding efficiency; at the same time, it is also equipped with a limiter device, which only grinds the material and prevents the grinding of the rollers. Accidental ring contact can cause vibration or even wear of the equipment.
2. Low operating cost of raw meal vertical mill
(1) Low energy consumption: The grinding roller is used to directly crush and grind the material on the grinding disc, which has low energy consumption and saves energy consumption by 40% to 50% compared with the ball milling system.
(2) Less wear and tear: Since the grinding roller does not directly contact the grinding disc during work, and the grinding roller and the lining plate are made of high-quality materials, the service life is long and the wear and tear is small.
3. The raw meal vertical mill is easy to maintain
Just flip the rocker arm and replace the roller sleeve and lining plate, which is convenient and quick. At the same time, it reduces downtime losses and saves labor costs.
