Do You Know The Cement Mill What Is Made Of ?

Do you know what is cement mill ?it is the equipment used to grind the hard, nodular clinker from the cement rotary kiln into the fine grey powder that is cement. Most cement is currently ground in ballmills.Cement mill is normally driven by electric motors.The output achieved by a cement mill system varies with the mill power, the fineness of the product and the hardness of the clinker. In the technics of Cement production process, People usually choose limestones and clays as the main raw materials, crushing, concocting, grinding them into cement raw meal, feeding them into cement kiln,Cement clinker is usually ground using a ball mill.After being calcined maturity, adding appropriate amount of gypsum (sometimes mixing the mixed material or admixture) then being grinded, and the cements form.


Naturally,the next part about main components of a cement plant.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 rotates approximately once every couple of seconds.The drum is generally divided into two or three chambers, with different size grinding media. As theclinker particles are ground down, smaller media are more efficient at reducing the particle size still further.Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rateof incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuitsystem, coarse particles are separated from the finer product and returned for further grinding.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.

Inside a cement mill. The part-ground clinker and steel grinding media are clearly visible .From the above ,we know what is the cement plant and how to work it .
