Effects of grinding aid dosage on circuit performance and,

30/12/2020· The average residence time of the material inside the mill under the reference condition was 25.44 min, while it was only 10.67 min when 450 g/t of GA was added. As the dosage of the added GA increased, the residence time of the cement inside the mill was shortened and consequently the size reduction inside the mill also decreased.Optimization of continuous ball mills used for finish,,The treatment time of 15 min is comparable to residence times measured in industrial-scale ball mills (Makokha et al., 2011; Schnatz, 2004; Shi, 2016).Modeling and Optimization of Cement Raw Materials,In , under different ball charge filling ratios, ball sizes, and residence time, a continuous ball mill is studied for optimizing cement raw material grinding process. In [ 5 ], an adaptive control framework is presented for raw material blending process, and corresponding optimal control structure is discussed too.
