Large pieces of material must first be crushed to the required particle size by a crusher, then conveyed to a storage hopper by an elevator, and finally fed evenly, quantitatively, and continuously into the main grinding chamber by a feeder. During operation, the material to be crushed is added into the machine through the feed hopper on the side of the casing. The grinding rollers, suspended on the main grinding chamber's spider frame, revolve around the vertical axis while simultaneously rotating on their own axis. Due to centrifugal force during rotation, the grinding rollers swing outwards, pressing tightly against the grinding ring. The scraper scoops up the material and delivers it between the grinding rollers and the grinding ring, where the rolling and crushing action of the rollers achieves the purpose of crushing the material.
Powdering Process: After grinding, a blower blows air into the main casing, agitating the powder. This powder is then sorted by an analyzer located above the grinding chamber. The analyzer uses the centrifugal force generated by the rotation of its internal impeller and the drag force of the airflow to classify the powder. Coarse powder that does not meet the fineness requirements is thrown against the cylinder wall and falls back into the grinding chamber under centrifugal force. Powder that meets the specifications enters the cyclone collector with the airflow and is discharged through the powder outlet as the finished product. The airflow returns to the fan through the return air duct at the top of the large cyclone collector. The airflow path is circular and flows under negative pressure. The increased air volume in the circulating air path is discharged through the exhaust gas duct between the fan and the main unit, and enters the small cyclone collector for purification. Some equipment is equipped with a pulse bag filter for deep purification of the residual air to meet environmental emission standards. In addition, modern pulverizing equipment often integrates an automatic control system to achieve precise control of grinding roller pressure, remote operation, and fault diagnosis, thereby improving operational stability and automation.
