Superfine slag of blast furnace water quenching, application of Superfine cement
Blast furnace slag is a kind of industrial waste, after high temperature sintering with high activity, currently used as cement admixture. With high-strength concrete (C80) increases in consumption, useful application of blast furnace slag powder in place of Silica fume. Study results show that adding 30% after modified slag concrete 28D strength of reach and exceed no slag concrete, early strength low. Sand ordinary Silicon mineral raw materials, after grinding down to the surface area over 4000cra2/g, with higher activity. Same as the blast furnace slag, Super of Xihe River sand after the joining of high strength concrete in improving the strength of concrete at the same time, reduces the heat of hydration, improves the liquidity of pump concrete. Superfine cement excellent reinforcement and liquidity, such as the reinforcement of cracks in the dam.
Portland cement mill and cement mill grinding plant
Cement is an important building material in modern construction, road construction etc. Cement is made from limestone, gypsum, coal etc.In the production process of cement, crushing and grinding mill is necessary. Cement mill can be used throughout the production process of cement. In limestone crushing and grinding, cement mill can grind the limestone particles in the finely powdered coal plant spray cement can be used to grind finepowder coal plant mill grinding cement plaster will be spray of ultrafine powder of plaster in the process of grinding clinker, cement mill is also important.
