Advanced Low-Power Continuous Cement Mill

The roller is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further. Cement clinker is usually ground using a cement mill. This is essentially a large rotating roller containing grinding media - normally steel balls. As the roller rotates, the motion of the balls crushes the clinker. The roller rotates approximately once every couple of seconds.Grinding systems are either "open circuit" or "closed circuit." In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Charge by screw, discharge by grid, make use of rubber wearable liner board; cement mill make motor drive decelerator to drive small belt wheel, then make triangle belt drive large belt to drive mill rotate.It’s allowable to add different material and additive to charge inlet of each mill, add wearable material at the first mill, then add easy abrasive material in following mill, reduce extra milling to increase the weight of mill.Gypsum is interground with the clinker in order to control the setting properties of the cement. Clinker grinding uses a lot of energy and the cement becomes hot - this can result in the gypsum becoming dehydrated, with potentially undesirable results - see the link at the bottom of this page for more information.As a leading manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant. We also supply individual crushers and mills as well as spare parts of them.rotary cement kiln: http://www.sinojawcrusher.com/companyproducts/Cement-Rotary-Kilnis.html
