Vertical Roller Mill Working Principle


LUM ultrafine vertical roller mill is mainly composed of motor, reduction drive, roller device, mill equipment, pressure device, classifier, the body and the gas station, etc. Vertical roller mill drive power depends on the pressure and the design parameters of the roller applied to the disc, if too much material on the disc, but did not keep up with the grinding pressure, the low grinding efficiency, grinding power consumption; if the grinding pressure, also increases the grinding power, will adversely affect the device. Vertical roller mill production standards and stable operation, give full play to their energy consumption, reduce the cost advantage is also important. At the same time to increase production, the operator should pay attention to appropriately increase the hot air, ventilation mill, grinding pressure, water quantity and other parameters to ensure pressure stability.

The vertical drive motor of LUM Ultrafine Vertical Roller Mill through reducer rotating disc, solid material feeding device through air lock from the inlet into the disc center, the centrifugal force field and thrown to the surrounding disc by repeated vertical roller mill rolls and crushed. in the role of a rapidly rotating rotor under , grits are separated again fall into the center of the grinding disc, powder into the air from the upper part of the grinding mill, in the collecting device is collected, namely products.

LUM Ultrafine Vertical Roller Mill Application


LUM Ultrafine Vertical Roller Mill is widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as grinding quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
