Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

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

Cement production will experience several procedures which include raw materials blending process and burning process, cement clinker grinding process, and packaging process. Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO 2 ), alumina (Al 2 O 3 ), and iron oxide (Fe 2 O 3 ).
