Repair of Vertical Rolling Mill in Cement Plants. The VRM's function is to crush the materials into very fine particles, just prior to being stored or after the primary crushers. The VRM components are subjected to severe wear which can increase dramatically when high silica content is found in the raw materials or where mills are grinding slag.
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 …
