Work principle of calcite grinding mill

calcite grinding mill
HGM series calcite grinding mill is mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe. When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air blower constantly inhales air, airflow with crushed materials are brought to 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. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.

Features of calcite grinding mill

calcite grinding mill
High Efficiency
Under the same finished final size and the same motor power, the capacity of ultrafine grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcite carbonate.
High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 250 meshes and 2500 mesh (74-5 micron), and the product fineness can reach D97≤5μm.
Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
