This can be counted yearly as over 6% of global energy consumption. More than 60% of this tremendous energy has been used in the comminution units (crushers and mills) to reduce the size of raw materials and clinker 1–3. In the mid-1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage.
Features of Vertical Pre-Grinding Mill: 1. Its grinding roller employs forced lubrication oil feeding mode to effectively prevent dust from entering into bearings. 2. Made of high-chromium cast iron, its lining plate of grinding disc and roller shell are easy to change and have a service lifespan more than 30000Hr. ... among which the clinker ...
Clinker manufacturing begins with the mining of limestone. The limestone is crushed and transferred via the belt conveyor into the raw mill for grinding. The raw material grinding section comprises of a vertical roller mill, mill fan, separator and cyclone as well as all the ductwork and the control dampers.

The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.
The structure that has the turn table and 2～4 rollers to mill clinker is basically the same as vertical roller mills for raw materials. But the roller mill for pre-grinding have no classifier and air sweep. The pre-ground clinker is discharged outside mill, and separated with vibrating screen. | Mon, 11/30/2015
