Application of Three roller mill, YGM7815/YGM8314 mill:
Three roller mill, YGM7815/YGM8314 mill is used to grind barite, limestione, ceramics, etc, such non-inflammable and non-explosive stuff,which the hardness is below 9.3 Mohs 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 30-1250 mesh(It can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.
Operating principle of Three roller mill, YGM7815/YGM8314 mill:
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.

Working Features of Three roller mill, YGM7815/YGM8314 mill:
Three roller mill, YGM7815/YGM8314 mill has the similar working principle as Raymond mill, but its grinding device is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller , which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.
