The vertical roller mill (VRM) is a kind of large equipment that widely used in cement materials industry. Since it always needs to work in the environment of heavy load, high temperature, high pressure and electromagnetic radiation interference, it breaks down easily. If the incipient faults information can't be detected in advance,

parts of a vertical roller mill grinding OPC is fairly low and maintenance of wear parts, i.e. reversal, hardfacing or replacement, can usually be scheduled to take place say once per year to follow the plant's kiln maintenance program.
