Gypsum grinding mill is the new type mining equipment for making micro powders and widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on. Besides gypsum, our gypsum grinding mill also can be used in mica, carbon black, graphite, fluorite, potassium feldspar, pigment, limestone, calcium carbonate and other more than 200 kinds stone materials grinding.

Do you know how does the gypsum grinding mill work?

When the gypsum grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grind by the rollers.The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector.

Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.
