Micro Powder Grinding Mill is a device that breaks solid materials into powder by grinding, Such comminution is an important unit operation in many processes. It is usually used in Metallurgy, building materials, chemical and mine industries.

Micro Powder Grinding Mill is suitable for the super fine grinding of all kinds of crisp materials whose Moh’s hardness is below 7, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, white mud, mica, refractory material, glass, total about 1000 kinds of materials.

Internal structure and Working Principle of Micro Powder Grinding Mill

Micro Powder Grinding Mill is mainly formed by mill body, blower fan, ultra-fine analyzer, finished product cyclone container, bag de-duster and air pipe. The elevator, storage bin, electric control cabinet, powder feeder and crusher are optional for the demands of customers.

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.
