Cement grinding cement production units will be finished in the final product of cement production stage of the formation of a separate independent . This phase will add the right amount of mixing cement clinker material regalia , output of finished cement. Cement production, raw materials can be divided into three general preparation processes , etc. made of clinker and cement . Silicate cement production process has a representative in cement production , is composed of limestone and clay as the main raw material, crushing , ingredients, made from finely ground raw material , and then fed into the kiln burning mature , and then cooked plus the amount of gypsum material ( sometimes mixed with mixed material or admixture ) from finely ground .
Layout of cement production in the mining area to build cement clinker production line to build cement grinding station near the cement sales market , in order to reduce transportation costs. If the clinker production line was built around the city , each 1t clinker production requires about 1.6t cement raw material , increased 60 percent to transportation costs . If the cement grinding and clinker production line was built together in the mines, because most of the mixed material is waste generated in the city , these hybrid materials to be transported to the cement plant built in the vicinity of the mine , the ground into cement and then transported to the city , increasing transportation costs. Therefore , clinker production line to be built in the vicinity of mines, cement grinding station to be built in the vicinity of the market . Cement grinding station is an industry with green benefits .
