VRM audits and optimisation

2021-11-16  The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance.

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. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles.

How Is Cement Produced in Cement Plants Cement

Cement plants are usually built near the quarry of limestone so the quarried limestone can be transported to the cement plant directly by belt conveyor or other conveying systems. If the distance between the quarry and the cement plant is too long to use conveyors, the limestones will have to be transported by trucks, which means higher transportation fees and inconvenience.
