The principle structure of high-pressure roller mill
High-pressure roller mill is a type of new mineral rock grinding equipment with high efficiency and energy-saving developed based on the lamination crushing principle. The materials enter into the crushing cavity between 2 rollers passing the feeding device with the help of the gravity when working. The material is brought into the cavity continuously. The material is forced to accept the direct pressure from the surface. The 2 rotary rollers will press the material in the crushing cavity solid so that the particles in the group will bear pressure at multiple points. Thus, the material volume weight in the pressing area is 85% of the actual density. The particles are crushed in the group be mutual pressing. Different particle crushing is caused due to different pressures. So the particle size is widely distributed and the piece of material cake is discharged. The material cake contains some sub-particles. There are many cracks in the particles to reduce the particle strength, which is good for the following grinding to reduce the power consumption of the whole milling system significantly.
