Energy-Efficient Technologies in Cement Grinding IntechOpen
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Cement grinding unit cost. Take the annual output of 600,000 tons of large-scale cement grinding station as an example, there are three common options can be recommended: SCHEME 1: roller press + φ 3.2 ×13m ball mill; SCHEME 2: φ 3.8 ×13m closed mill; SCHEME 3: clinker fine crusher + cement roller press+φ 3.2 ×13m ball mill.Cement Grinding Unit Cement Grinding Plant Cement Grinding
