The cost of a motor of a Gearless Mill Drive depends mainly on two parameters: • Diameter of the motor, • Rated Torque of the motor, The diameter of a GMD motor is defined by the diameter of the mill, as the motor is wrapped around the mill. The torque of the motor is what makes the mill turn and torque
And the motor realizes the operation of the ball mill through reducer. During the operation,the hollow shaft in the center of the ball mill drives the mill body to rotate under the driving of the power system. • Edge driving ball mill: the motor drives the gear on the edge of the cylinder through the reducer to drive the cylinder movement. 6.
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 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
