improving energy efficiency. the cement industry is continuously improving grinding and mixing methods to improve the performance of different types of cement as well as testing new substitutes and additives. the shift in grinding technology includes wider grinding with vertical roller mills and roller presses, high efficiency separators get price,how to improve working efficiency of ball mill,improve material of liner and effective volume of cylinder. increasing the effective volume of the ball mill can increase the efficiency of the mill production. ordinary alloy linings are thick and heavy, which reduces the effective volume of the mill and increases the power consumption, which reduces the production efficiency of the ball mill.
