HVM vertical mill is a kind of safety, environmental protection, energy saving, high efficiency, which is designed and developed through painstaking research on the basis of widely absorbing the advanced technology of various vertical mills at home and abroad and drawing on a lot of engineering application experience. Advanced grinding equipment integrating 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 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 passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly 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 ground 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.

Specifications And Technical Parameters Of HVM Raw Vertical Mill

【Product Advantages】

1. High efficiency and energy saving
(1) High grinding efficiency and low energy consumption, compared with ball mills, the energy consumption is 40%-50% lower;
(2) The single-machine production capacity is large, and the low-valley electricity can be used;
(3) Vertical mill technology and equipment is a new energy-saving and consumption-reducing technology vigorously advocated, which is conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even the whole country;

2. Easy maintenance and low operating cost
(1) The grinding roller can be pulled out of the machine by hydraulic device, the replacement of the roller sleeve lining plate and the maintenance space of the grinding machine are large, and the maintenance operation is very convenient;
(2) The roller sleeve can be turned over for use, extending the service life of the wear-resistant material;

3. Stable product quality
(1) The material stays in the pulverizer for a short time, and it is 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 product adaptability.

4. Low comprehensive investment cost
It integrates crushing, drying, grinding and conveying. The process is simple, the system equipment is small, the structure layout is compact, and the floor area is only 50% of the ball mill. It can be arranged in the open air, and the construction cost is low, which directly reduces the investment cost of the enterprise. .

5. Environmentally friendly
(1) The whole system of HVM vertical mill has small vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust spillage, which can basically realize a dust-free workshop.

6. High reliability
(1) The grinding roller limit device is used to avoid the violent vibration caused by the material cut off during the working time of the mill;
(2) Adopting a new type of grinding roller sealing device, the sealing is more reliable, and there is no need to seal the fan, which further reduces the oxygen content in the mill and has better explosion suppression performance.
