The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a twoinputtwooutput model was applied to describe the system, in which some key indicators of the process were ignored. To this end, a three ...

Mill speed has profound effect on the ball trajectories, impact force and power draw. The mill can reach the best performance at the mill speed ranging from 70% to 80% of critical speed, and correspondingly the maximum percent of the impact force between 600 and 1400 N is obtained. For the 80% of critical speed, the measured power draw has a ...

mill drives (RMDs) offer the best solution. Three of the most common drive types for RMDs are low speed motors without a gearbox, high speed motors with a reduction gearbox, and variable speed drives (VSDs). No gearbox: The low speed motor is connected directly to the pinion. The rated speed is typically around 200 to 400 rpm. Synchronous ...

The minus 152 mm (6 in) product is conveyed onto a 29,940 Mt (33,000 st) crushed ore stockpile, reclaimed by three vibrating feeders, and then conveyed to the SAG feed chute at a targeted rate of 136 Mt/hr (150 st/hr). The control strategy for the SAG mill is fairly basic. Parameters which can be adjusted are feed tons per hour and mill speed.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
