HighPressure Roller Mill The highpressure roller mill, also called the roller presser or the extrusion mill, is a grinding equipment 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 had
