Calcium carbonate grinding machine :
The calcium carbonate grinding machine is a new kind of large scale power grinder which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years' research of mills, LM vertical calcium carbonate grinding machine is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand.
The calcium carbonate grinding machine adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.
Working principles of calcium carbonate grinding machine :
The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the calcium carbonate grinding machine from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the calcium carbonate grinding machine , the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill. In the process of the contact of airstream , the materials are dried to meet the clients' need at the proper moisture. Through the adjustment of the angle between the separator and the leaf of wind's direction (not suitable to the small type of LM vertical grinder ), and also the speed of the separator rotor, it can reach the proper fineness of the materials.
Calcium carbonate grinding machine features:
1.Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry
2.Specialized for the high production of gangue powder making in coal industry
3.Specialized for the high production of various of chemical raw material powder making in the chemical industry.It is a 4.necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.
