Cement clinker is normally ground working with a ball mill . This really is essentially a big rotating drum containing grinding media - commonly steel balls. As the drum rotates, the motion with the balls crushes the clinker. The drum rotates roughly when just about every couple of seconds.
The drum is normally divided into two or 3 chambers, with distinctive size grinding media. As the clinker particles are ground down, smaller media are much more effective at lowering the particle size nevertheless further. manganese processing plant
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit program, the feed rate of incoming clinker is adjusted to achieve the desired fineness with the product. In a closed circuit method, coarse particles are separated from the finer item and returned for additional grinding.
Gypsum is interground using the clinker to be able to manage the setting properties with the cement. Clinker grinding makes use of a lot of power and the cement becomes hot - this can result in the gypsum becoming dehydrated, with potentially undesirable outcomes - see the link at the bottom of this page for a lot more data. anthracite crushing
