Oct 01, 2019 Ball mill is a kind of widely used engineering machinery with low working efficiency [1,2]. Since the advent of the ball mill, researches on its grinding performance mainly aimed at the aspects of fill rate, rotational speed, ratio of steel balls, ratio of grinding medium and abrasive, number of lifter bars, the shape of lifter bars [3,5].

The calculation of the motor power. In fact, the motor power is directly affects the level of overall efficiency. At the time of production of basic attributes, motor power and crushing material crushing ratio, rotor speed and high productivity and low have a great relationship.

Feb 25, 2015 Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size 13 mm ( 80 % passing).
