Role Of Ball Mill Pressure

Role Of Ball Mill Pressure

As the grindability of the raw material increases, so does the effi- ciency of high-pressure grinding – and the polycom reveals its full potential. compared to a roller mill, it is thus able to save up to 20 percent of the energy required for grinding; compared to a conven- tional ball mill, it can even save up to 50 percent..
