The advantages of Vertical Roller Mills: VRM is comparatively more energy efficient and on an average these system consume 25% less energy in comparison to the conventional Ball Mills. VRM has higher drying capacity and can dry up to 25% moisture, as against maximum drying capacity of 8-10% in the conventional Ball Mill system.

UBE Vertical Roller Mill performs drying, grinding, classification and pneumatic transportation simultaneously. Material is fed at a constant rate through the chute and fall into the center of table. Then the material gets carried to periphery of the table by centrifugal action and is crushed between the rotating grinding track and the grinding ...
In our measure we estimate an energy savings of 7 kWh/t raw materials through the installation of a vertical or horizontal roller mill. An additional advantage of these mills is that they can combine raw material drying with the roller process by using large quantities of low grade waste heat from the kilns or clinker coolers [22] .
Because the rollers are hydraulically raised, the breakout torque of the filled mill amounts to only 40 % of the full-load torque. A "standard motor" can easily deliver this starting torque. The installed motor power is related to the mill's energy requirement and is determined in the technical centre during the grinding test.
LM vertical roller mill is a kind of high efficiency and energy saving product perfectly combined with 30 years of mature vertical grinding technology. It adheres to advanced powder making technology and multi-function, adopts reasonable and reliable structural design, and coordinates with advanced technological process.
