Grindability of a 95/5 OPC at various Blaine fineness: o 27-32 kWh/t at 3,000 cm²/g. o 39-47 kWh/t at 4,000 cm²/g. o 58-69 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not required ...
The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 2-4 minutes.

Cement mill is widely used in cement, silicate products, new building materials, refractory materials ...
For raw material grinding a quadropol® vertical roller mills QMR² 45/23 was contracted to serve the kiln line, while for cement grinding two identical QMC² 45/23 were considered …
10 Difficult Problems about Raw Grinding with Vertical Roller Mill Systems and their solutions. First : High vibrations. Potential causes: Too many fines in mill feed. Material bed on grinding table not stable. Proposed solutions: Increase feed size. Adjust crushers. Maybe eliminate a crusher. Expected results: Less vibrations.
cement grinding in vertical mills requires the presence of a continuous water jet in order to stabilize the bed of grinding material and therefore prevent the development of excessive vibrations. The water required for this task is stored in normal tanks and pumped directly inside the mill on the grinding table,
