High Pressure Grinder Series
  The machine is used to grind barite,limestione,ceramics,etc,such non-inflammable and non-explosive stuff which the hardness is below 9.3Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material,The fineness size is adjusttable in the range of 60-1250 mesh(It can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special devic in the machine.
  In the main frame,a 1000-1500Kg high pressure spring is fixsd to the roller suspender.After the grinder is put into effect ,the roller will circumgyrate around the main shaft and rolls closely 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 grinder powder goes into classifier along wiht the circulaion wind of the blower and the standard finesspowder is guided to cyclone collector as finished and lager size stuff falls back to the grinder or regrinding .The circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust clesner for purification.
  When there is abrasion between roller and ring,it is recommended to adjust the lengh of the spring to maintain the constant pressure between the roller and the ring hence to be ensured ,the stable output and findness.
