Cement mill - Wikipedia

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Contents 1 History 2 Materials ground

Cement Milling

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4 .2H 2 O).

Loading of hot (>150 ºC) clinker to concrete silos should be avoided as spalling and de-lamination will progressively weaken the silo walls. High free lime clinker must be blended in to mill feed with circumspection to ensure that the cement is not expansive. Outside stockpiling of clinker is not usually worthwhile if subject to rainfall, it ...

What is Cement Clinker? Composition, Types & Uses - …

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

Cement, How It Is Produced - Mine Engineer

The discharge from the kiln is called clinker, as it resembles small rocks or residue from a blast furnace. The clinker is the cement in "lump" form. The particle size range for clinker is from about 2 inches to about 10 mesh. The clinker is then ground in a ball mill and shipped to users as Portland Cement.
