A molecular modified PCEtype GA was selfsynthesized, and the grindability concerning grinding duration and particle size distribution of ground cement was evaluated. Setting time, flowability, hydration heat, mechanical properties and microstructure of the ground cement were also investigated. The results show that: PCEtype GA is effective in cement grinding. With % PCEtype GA added ...

In another word, the cement grinding mill can increase the cement quality and guarantee the qualification rate of cement. In general, cement mill can both apply for dry cement production and wet cement production. Commonly, there are three hot types of cement mill in the cement industry: cement ball mill, Raymond mill, and vertical cement mill.
