Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a calcium oxide high-speed swing grinding machine. Background Art

[0002] The working principle of the existing grinding mill is that the material enters the cylinder through the feed port and falls onto the base. The driving mechanism drives the main shaft to rotate, and the main shaft drives the scraper and grinding roller to rotate. The scraper throws the material upward, and the material enters between the grinding roller and the grinding ring. The grinding roller generates outward pressure under the action of centrifugal force, so that the material is ground into powder. The air inlet is connected to the blower to form an airflow, which enters the cylinder through the air inlet. The powder that meets the fineness specification enters the classifier under the action of the airflow for classification. The powder that does not meet the fineness specification will fall and continue to be ground, which reduces the production efficiency of the grinding mill.
