The material is crushed into small particles by the crusher, transported to the storage hopper by the bucket elevator, and then fed into the ultrafine crusher for grinding by the electromagnetic vibration feeder. The grinding roller device suspended on the plum blossom rack inside the host rotates around the central axis, and the grinding roller simultaneously rotates around the grinding roller axis. Under the action of centrifugal force, the grinding roller swings outward to press the grinding ring, so that the abrasive on the shovel is placed in between. As the rolling of the grinding roller has reached the crushing and grinding effect. The powder in the grinding chamber is blown by the airflow of the blower to the analyzer above the main machine for analysis. Those that are too fine or too coarse still fall into the main machine for regrinding, while those that meet the specifications of fineness enter the large cyclone collector with the airflow. After collection, they are discharged through the discharge pipe to obtain the finished product. The purified airflow Flow into the blower through the pipeline on the large cyclone collector.

The air path is circular, and except for the positive pressure from the blower to the grinding chamber, the airflow in all other pipelines flows under negative pressure, preventing dust from overflowing and minimizing environmental pollution. Due to the moisture contained in the material evaporating into gas during grinding, the gas leaked into the air duct at the joints of various valves and feed ports in the pipeline leads to an increase in the air volume in the circulation air path. The increased air volume isbag-type dust collectorAfter purification, it is discharged.
