VRM REPAIR IN CEMENT PLANT – Techno Cast

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.
