Iron ore grinding process,process design for grinding

When the grinding product is required to contain -200 mesh not more than 60~70%, a closed-circuit grinding process can be used. In closed-circuit grinding, the returned sand from the classifier is mostly finer than the original ore. The returned sand is mixed with the ore newly fed into the mill, so that the average particle size of the ore
