A grinding mill for potassium sulfate processing

Abstract

This utility model provides a grinding mill for potassium sulfate processing, relating to the field of grinding mills. It includes a frame, a grinding hood, a housing, and a grinding assembly. The housing and grinding assembly are fixedly installed on the top of the frame. The grinding hood is fixedly installed inside the housing, and the output end of the grinding assembly is located inside the grinding hood. Multiple powder outlet grooves are circumferentially and evenly spaced on the outer surface of the grinding hood. A blowing assembly is also provided inside the housing, with its output end facing the powder outlet grooves. A powder collection box is located at the bottom of the housing, and a feeding assembly connected to the inner cavity of the grinding hood is located at the top of the housing. The blowing assembly blows airflow through an air nozzle onto the outer wall of the grinding hood, blowing coarse particles that have not reached the required fineness back to the grinding area, achieving dynamic grading. Fine powder enters the powder collection box through the powder outlet grooves; coarse powder is blown back into the grinding hood by the airflow for further pulverization. The airflow also removes dust generated during the grinding process, preventing blockages and improving equipment operating efficiency.
