Cement Ball Mill Structure. When Ball Mill is working raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls steel segments etc.) when the cylinder rotates around the horizontal axis at a certain speed Under the action of centrifugal force and friction force the medium and the
The cement pregrinding system. The most noticeable feature of the roller press cement pregrinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.
As part of the grinding process calcium sulfate is added as a set regulator usually in the form of gypsum (CaSO 4 .2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both aircooling and watercooling including spraying water inside the mill.
