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 ...
Ball mills have been used as the main grinding equipment for finished cement production for over 100 years. Although simple to operate and costcompetitive relative to other technologies, the low efficiency of ball milling is one of the main reasons for the development of more efficient grinding processes in recent years.
Cement grinding unit cost. Take the annual output of 600,000 tons of largescale cement grinding station as an example, there are three common options can be recommended: SCHEME 1: roller press + φ ×13m ball mill; SCHEME 2: φ ×13m closed mill; SCHEME 3: clinker fine crusher + cement roller press+φ ×13m ball mill.
4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.
