The high-pressure air blower constantly inhales air within the grinding mill 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.
Raymond grinding mill can process Calcium Carbonate into different specifications, fineness and output and it is especially suitable for the processing and production of Calcium Carbonate powders. Compared with common powder grinding mills, this equipment has high efficiency, low electricity consumption, small coverage size and one-time investment. The final granularity of Raymond grinding mill produced by Clirik Machinery can be arbitrarily adjusted in the range of 30-425 mesh and some materials can reach 2000 mesh so that the Calcium Carbonate powders can meet the fineness requirement in the market, so that it is ideal Calcium Carbonate powder processing equipment.if you are interested in our powder grinding mill,please contact us.
