Bentonite is a kind of hydrous clay mineral, and it mainly consists of montmorillonite. Bentonite has special properties, like Swellable, adhesion, adsorption, catalytic, thixotropic, suspension and cation exchange, so it is widely used in various industrial fields.

How processing bentonite to obtain maximum economic benefits? Modern industrial processing equipments are necessary!

The basic equipment is crushing and grinding machine:
HGM series grinding mill mainly consists of grinder, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, vibrating feeder, and packing machine.
YGM series high pressure grinding mill has 3R/4R/5R three types of grinders, you can choice it by your needs.


Working principle of HGM series bentonite grinding mill:
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.
When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
The high-pressure air blower constantly inhales air within the vertical grinder machine and, in turn, the air flow 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 an 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.
