As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.

The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also to generate a constant specific ...

Circulating load is typically 800%. Roller mills are prone to vibration due to an unstable grinding bed. A major cause of material instability is fine, dry mill feed which can usually, be mitigated by spraying water directly onto the bed. VRM Working principle Vertical roller mill.
