As a complete set of mechanical, electrical, and hydraulic equipment, the high-pressure roller mill adopts the principle of high-pressure material layer crushing. It is mainly appliable in crushing and grinding of materials with compressive strength less than 300MPa, protodyakonov scale of hardness within 5-16 and humidity less than 10%, and is featured by large crushing ratio, fine discharging particle size, output increase and consumption reduction.If the material undergoes high-pressure extrusion, a large number of cracks will be generated inside, and the Bond work index will be reduced, which can effectively reduce the grinding power consumption of the subsequent mill.
