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 ).
