The ring roller mill uses the principles of impact, extrusion and grinding to crush materials. There are multiple layers of grinding rollers and grinding rings installed, and the material first falls between the uppermost grinding rollers and grinding rings. There is a large movable gap between the grinding roller installed on the grinding roller bracket and the pin shaft. When the material passes through the gap between the grinding roller and the grinding ring, the material will be crushed by the impact, extrusion and grinding of the grinding roller. When the material passes through the multi-layer grinding rollers and grinding rings from top to bottom, the material will be ground many times. Under the action of gravity, the crushed material falls to the bulk material tray at the bottom and is thrown to the airflow channel, and is brought into the classification area at the top by the airflow; the classifying wheel classifies the powder, and the qualified fine powder passes through the classifying wheel and enters the The dust collection system collects, and the coarse material is thrown to the inner wall of the diversion ring, and falls back into the crushing area for crushing.
The ultra-fine roller mill drives the main shaft to rotate through the transmission device. The upper end of the main shaft is connected to the rotor frame. The frame is equipped with an auxiliary shaft and a grinding wheel is installed on the auxiliary shaft. When the main shaft rotates, the auxiliary shaft rotates with it. The grinding wheel on the auxiliary shaft not only revolves around the main shaft, but also rotates around the respective auxiliary shaft. The grinding wheel generates strong centrifugal force during the revolution and rotation process, and has a strong roller grinding action with the stator. The ground material is driven by the centrifugal force and the rotating force field of the grinding wheel, and enters the grinding zone composed of the grinding wheel and the stator. The material is ground under the action of squeezing force and grinding force. The ground material falls on the slinger plate, which rotates with the main shaft. It slings the powder into the ring between the stator and the machine body, and rises along the shunt ring to the upper classifying chamber under the negative pressure of the system for classification. Qualified fine powder enters the collection system through the classification wheel, and the coarse material falls along the inner wall of the split ring into the crushing chamber to be ground again.
