High efficiency ball mill for cement grinding
How our cement ball mill work. Our cement ball mill grinds cement clinker, gypsum and similar materials of moderate moisture content in a one compartment or two compartment systems. As the crushing compartments rotate, the balls inside them grind the clinker. Ball size determines finished product fineness.
