Sizing A Motor & Drive System | Control Techniques
Motor-Drive sizing. To effectively size the motor, it is necessary to calculate the load inertia (JL). The ratio of load inertia to motor inertia (essentially, rotor inertia) gives a measure of how effectively the motor can control the load. A high inertia ratio indicates the system that will have difficulty controlling the load.

Ball Mill (Ball Mills Explained)
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.

Machine RPM Calculator – By Pulley Size & Motor RPM
The formula for machine RPM is mentioned below: Machine RPM= (Motor r.p.m × Pulley 1 Diameter)/Pulley 2 Diameter. Example: RMP= (1465 x 200)/250 = 1172 (rpm) Motor RPM is the rotational speed of the motor. Pulley 1 diameter refers to the diameter of the motor (drive) pulley. Pulley 2 diameter represents the diameter of the machine (driven) pulley.
