21 roller grinding mill for caco3

HGM 80 21 roller mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite,talc, mica, magnesite, ilite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite,graphite, fluorite, rockphosphate, Kalium ore, pumice, fly ash, etc., totally more than 100 kinds of materials.

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

Afer 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 turm 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 of main equipment through reducer, and all the grinding rollers are olling 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 where the materials are repeatedly pressed, crushed and grinded by the rllrse Then the materials fall into multiple layers and to be crushed and ground continuously to micro

The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifer whose high-speed impeller will screen the airflow. the unqulifed particle size will fall and returm to the mill for being reground while the qualifed 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 fiter bags, which is caused by the instanty 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 additin, filtered
clean air will be emitted from the air outlet of mufler in the end.
