Vertical Roller Mill

Vertical Roller Mill Overview

Vertical roller mill is used in cement raw meal grinding processing, cement clinker, slag and coal cinder, with characteristics of simple structure, low cost of manufacture and use.

Vertical roller mill includes the body, disc devices and transmission device, organism and the disc set have certainty Rotary Center centering structure between device, Disc device fixed to the bottom of a rotating guide disc devices through Rotary guide turning on the supports in the fuselage, disc devices connected to the transmission.

Vertical Roller Mill Unique Benefits

  1. The final products has little iron and the whiteness and purity are quite high.
  2. It is quite environmentally friendly, LUM is of little dust and noise.
  3. Vertical roller mill use PLC/DCS automatic control system, well save the cost of operators.
  4. Vertical roller mill has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.

how does the Vertical Roller Mill work?

Motor through reducer drive disc rotates, the material through the air lock feeder falls from the inlet central disc, while hot air from the inlet into the mill. As the disc rotates, the material under the centrifugal force, moving to the edge of the disc, the disc through the annular groove when subjected to roller compacted and crushed.

After crushing the material in the disc edges with high-speed airflow from the air ring, large particles fall directly on the disc re-grinding, airflow through the upper part of the separator material when, under the effect of rotation of the rotor, meals fell from the cone disc re-powder grinding, qualified powder grinding out together with the airflow through the dust collection system to collect, namely products that contain moisture material is dried in hot air in contact with the process, by regulating the air temperature, the humidity of materials to meet different requirements, to achieve the required product moisture. By adjusting the separator can achieve the desired thickness of the different products.
