Abstract:
The article considers the value of the ball load of the mill, corresponding to its maximum productivity, depending on the speed of the mill drum and the analy-
sis of the value of the ball load when the speed of the mill drum changes. And also considered power consumption and specific energy consumption.
Keywords:
Ball mill, correlation coefficient, MShS 32х45, rotation frequency, power consumption, speed, specific energy consumption.
