Lin, X. Liang, J. Modeling based on the extreme learning machine for raw cement mill grinding process. in Proceedings of the 2015 Chinese Intelligent Automation Conference 129138 (2015).
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.

Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.
With the introduction of the high compression machines such as High Pressure Grinding Rolls (HPGR), Vertical Roller Mills (VRM) and Horomills, efficiency of the grinding circuits was improved in terms of energy and downstream effects. Among these devices, vertical roller mills have an important position in cement and mining industry.

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.
The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.
Effect of Grinding Aids on Wet Grinding. A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon blacks, wool grease, calcium sulfate, urea, asphaltenes, etc. Figure 426 shows a typical comparison ...
