The role of cement grinding station

- Sep 20, 2018-

The cement grinding station is a cement finished product production unit formed by separately separating the final finished product stage in cement production. At this stage, cement clinker is added to an appropriate amount of mixed materials for grinding to produce finished cement. The production of cement can generally be divided into three processes: raw material preparation, clinker calcination and cement production. The production process of silicate cement is representative in cement production. It is made of limestone and clay as the main raw materials. After crushing, compounding and grinding, it is made into raw material, and then it is fed into the cement kiln to calcine the mature material, and then cooked. It is made by adding appropriate amount of gypsum (sometimes mixed with mixed materials or admixtures).

The layout of cement production is to build a cement clinker production line in the mining area and establish a cement grinding station near the cement sales market to reduce transportation costs. If the clinker production line is built near the city, for every ton of clinker produced, about 1.6 tons of cement raw materials are needed, and the transportation cost should be increased by 60%. If the cement grinding station and the clinker production line are built together in the mine, since most of the mixed materials are waste generated by the city, these mixed materials are transported to the cement factory built near the mine, ground into cement and then transported to the city. Increased transportation costs. Therefore, the clinker production line should be built near the mine, and the cement grinding station should be built near the market. The cement grinding station is an industry with green benefits.
