【Product Advantages】
(1) High grinding efficiency and low energy consumption. Compared with ball mills, energy consumption is 40%-50% lower;
(2) The single-machine production capacity is large, and the low-valley electricity can be used;
(3) Vertical grinding technology and equipment is a new technology of energy saving and consumption reduction vigorously advocated by the state
(5) 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;
(6) The roller sleeve can be turned over to extend the service life of the wear-resistant material; (7) There is no need to put cloth on the grinding disc before starting the machine, and the mill can be started with no load, eliminating the trouble of difficult starting;
(8) The wear is low, the grinding roller and the grinding disc lining are made of special materials, and the service life is long;
【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.
