Study of the power and productivity of ball mills of the Sadonsky Lead-Zinc Plant and the Mizursky Concentrating Plant

The review article examines the total power, productivity and maximum rotation speed of the drum and their impact on the technological performance of the ball mills of the Sadonsky lead-zinc plant and the Mizursky concentrating plant. Studies of ball mills were carried out at a working load with varying rotation speeds to determine the highest productivity when grinding lead-zinc ores. As studies have shown, optimal performance occurred at the rotation speed of the drum, the working area of the mills, with a preliminary drop of the grinding media - steel balls.
