The structure of high pressure grinding roller mill
The structure of high pressure grinding
roller mill is various, but its principle is basically similar. The roller press is mainly composed of feeding device, material position control device, a pair of sticks, rotating device (motor, pulley, gear shaft), hydraulic system, and horizontal leakage prevention device.
Basic structure diagram of high pressure grinding roller mill
1- drive system and torque balance device; 2 - the motor; 3- material layer adjustment device; 4 - hopper; 5- fixed roller system; 6- moving roller system; 7- energy accumulator; 8 - frame; 9- hydraulic cylinder;
The working principle
The material enters into the pressure zone between two rollers rotating in phase, under the action of friction of roller pressure surface and gravity of material column. As the roll seam becomes smaller and smaller, the pressure on the material layer becomes greater and greater. Finally, the material is pressed into the material cake and falls down between the two rolls.
