Inside the coal mill, the grinding part is composed of a groove type grinding plate and three convex grinding rollers. Under the action of spring force or liquid pressure, the grinding roller and the grinding plate are tightly pressed together to roll the raw coal between the grinding parts into coal powder, and the pulverized coal particles
In the direct cofired system, the existing mills designed for coal are used for grinding the cofired biomass. So for a given mill, given rotation, and energy input, it is necessary to know how much biomass would be ground. HGI gives the comparative ease of grinding with reference to standard coal.

Progress With Grinding Aids For Vertical Roller Mills. The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills VRMs should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
The vertical coal mill consists of many parts, among which the vertical mill grinding table and the grinding roller play a crucial role in the material grinding. The primary function of the table is to support the material bed and transfer the force generated by the roller to the lower speed reducer, and also transmits the torque of the speed
