coal triple roller mill for sale
PRM3841 vertical roller mill is used for cement raw meal material grinding,and the operating principle is : raw material fell on the central of grinding table through air locked valve and discharge pipe, raw material is dispersed equably and spread out to make it for a desired thickness material bed by constant speed rotating grinding table with the help of centrifugal function .During this process material is ground by many grinding roller at the same time,and crushed under the function of the rotor’s pressure. Material is ran to the outer edge of grinding table continuously under the centrifugal force,material which leaves the grinding table meets the hot air which comes into the mill through air ring and goes up into separator through the middle shell of mill,during this process material and hot gas do the heat exchange sufficiently,moisture content is evaporated rapidly. Separator control the grinding of the finished product export particle size, greater than the size of the provisions of the granules are separated, the returned to millstone, only allow meet the requirements by the particles.
