MAINPROCESSROUTES FOR THEMANUFACTUREOFCEMENT. There are four mainprocessroutes ; 1)Dry processraw materials are ground and dried to raw meal in the form of a flowable powder. 2) Semi-wet processthe slurry is first dewatered in filter presses. 7 MAINPROCESSROUTES FOR THEMANUFACTUREOFCEMENT. 3) Semi-dry process dryraw meal is ...

The wet process of cement manufacturing involves adding water to finely crushed raw material such aslimestone clayoriron orein a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln whereas no water is added in the dry process

Theprocessout clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by thisprocessknown asPortland cement. Thecement manufacturingis done by majorly by two methods known aswet process and dry processdepending on their mixing is done withwateror withoutwater.

There are two differentprocessesformanufacturing cement.wet process mineralsarewet ground(by addingwater) to form a slurry and thendried,dry process mineralsaredry groundto form a powder-like substance. Both theprocessesare in use and have their own advantages and disadvantages. While inwet process grindingis easier, in thedry processthere is a saving in fuel costs involved indryingup …

Portland cementcan be made by following two different processes – adryone and awetone. Joseph Aspdin first madeportland cementin his kitchen stove in England in the 19th century. Lime and silica make up approximately 85%of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

May 22, 2013· There are 2 chief aspects of themanufacturing process: First To produce a finely divided mixture of raw materials – chalk / limestone and clay / shale. Second. To heat this mixture to produce chemical composition There 2 mainprocessthat can be used inmanufacturing of Portland Cementthat is i)wet processii)dry process

Thedry processconsumes much less fuel as the materials are already in adrystate, whereas in thewet processthe slurry contains about 35 to 50 percent water. In a recent trend, the majority ofcementfactories are using thedry processofcement manufacturing.
