cement manufacturing brief description of a cement mill. cement clinker is usually ground using a ball mill. this is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. the drum cement ball mill design calculation. cement ball mill design calculation. offers 441 cement ball mill design products about of these are mine mill are other fabriion services and are grinding equipment a wide variety of cement ball mill design options are jul 04, 2020 cement mill and bag house clinker, along with additives, is ground in a cement mill. the output of a cement mill is the final product viz. cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.
aug 10, 2020 fill the container with small metal balls. most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. use balls with a diameter between and inside the mill. the number of balls is going to be dependent on the exact size of your drum.keep a low cut width and do a separate finish pass. the depth of cut has to be larger than the chip load, or you can get rubbing. usually something like chip load will be right for the finish pass.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 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
