Roller mill is a machine that uses the principle of material bed grinding to grind materials. No matter how its structure changes, its basic working principle is the same. There are two distinct pulverization principles for roller mills. The rotation of the grinding disc drives the rotation of the grinding roller.
The material moves towards the edge of the grinding disc under the action of centrifugal force. The well is nipped into the bottom of Hitachi crawler bottom roller and crushed. The speed of the grinding disc is relatively high, and the material enters the grinding disc. The material is not only crushed under the roller, but also pushed to the outer edge, crosses the retaining ring and falls into the wind ring, is carried by the high-speed airflow, and the large particles rupture and fall back to the grinding disc. The small particles are brought into the separator by the airflow, under the action of the rotating blades. Separation. The coarse powder is returned to the grinding plate for grinding again, and the qualified powder is carried out of the machine with the airflow.
