High-Pressure Roller Mill The high-pressure roller mill, also called the roller presser or the extrusion mill, is a grinding equip-ment based on the principle of material layer crushing. It was successfully designed in 1984, the first high pressure roller mill was applied in the cement industry in 1985, and by 2015 it hadIn the present incident, one of the rollers of grinding mill in cement plant failed during operation, exhibiting longitudinal cracking over inner surface. Deposition welding was carried out just before the incident to match the worn-out profile of the roller. Investigation revealed that the subsurface of the cracked region contained discontinuities Operational Failure of Vertical Roller Attached to a Grinding Mill
