Chalk powder is widely used in artificial stone, artificial floor tile, nature rubber, synthetic rubber , teeth plaste, glass, and so on. It not only could reduce cost , but also improve the related product’s function and performance, add the volume of products, and is the most widely used in inorganic filler master batch.
Ultra fine powder grinding mill is used to make calcite powder. It's also called Calcite stone grinding machine. This machine is designed by Clirik Machinery Co.,Ltd on the basis of over years experience. It is specializing in producting fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, the moisture under5%. It mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
Working principle of Chalk ultra fine powder grinding mill:
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 super fine powder 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 grinded by the rollers.
The high-pressure air blower constantly inhales air within the stone grinding machine 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.
