Processed Materials:
Limestone, calcite, barite, dolomite, potassium feldspar, bentonite, medical stone, rock phosphate, manganese ore, iron ore, quartz, active carbon, carbon black, ceramic, coal, etc..
LUM series superfine vertical roller grinding mills can be widely used to process the superfine dry powder of non-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.
The main motor drives the millstone to rotate through the reduction box, meanwhile, the air flow gets into the mill through air intake. The materials come out of the screw feeder and fall on the center of the millstone, and then they will move from the center to the edge of the millstone under the affect of centrifugal force. When they move across the grinding zone, they will get grinded by the rollers. Those materials in big pieces will be crushed and grinded directly while those small ones will get extruded and they will form a material bed in which intergranule and mutual grinding will take place. The grinded materials keep moving to the edge of the millstone until they are taken away by the air current at the air ring, and the big pieces will fall again on the millstone to be grinded. The materials in the air flow will go through the rotor vanes on the separator above.
