The grinding machine is suitable for grinding barite, limestone, ceramic, slag, and etc,the moh's hardness of which are  below 9.3 scales and moisture is below 6%. And more than 280 materials which are non-inflammable and non-explosive can be used in mining, metallurgy, chemical engineering and building material for high fine powder generating and processing. The Product size is adjustable in the range of 60-1250 meshes (the finest can be up to 2500meshes). It is possible to produce 10-60 mesh coarse powder through special device in the machine.

High Pressure Suspension Grinder Mill Operating Principle:

In the main frame,a 1000-1500kg high pressure spring is fixed to the roller suspender.After the grinder is put into effect,the roller will circumgyrate around the main shaft,and rolls chosely against the grinding ring effected by the high pressure is 1.2 degree than Raymond mill.
When the stuff is loaded into the grinding cavity,it is shoveled into the space between the roller and the ring for grinding.The grinded powder goes into classifier along wiht the circulation wind of the blower and the standard finenesspowder is guided to the cyclone collector as finished and lager size stuff falls back to the grinder for regrinding.The circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust cleaner for purification.

When there is abrasion between roller and ring,it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring hence to be ensured,the stable output and fineness.
