The raw coal enters the vertical mill bin: The reducer drives the millstone to rotate, and the raw coal enters into the mill through the feed port, scattering on the millstone. Grinding the raw coal: Due to the effect of hydraulic pressure, the extrusion between the grinding rollers and the millstone causes the big pieces of raw coal crushed.

The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.

The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.

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,
