Calculate and Select Ball Mill Ball Size for Optimum Grinding

10/21 · In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

How to determine if a screw will back drive

But if the application requires a ball screw for positioning accuracy, load capacity, or rigidity, there is a way for designers to determine the likelihood that back driving will occur. First, calculate the back drive torque, which is a factor of the load, the screw lead, and the screw efficiency: T b = back driving torque (Nm) F = axial load (N)

How to Calculate Total Mass or Load of Conveyor for Load Torque

Load torque with respect to drive pulley periphery = (Aforesaid total resistance) x (Drive pulley radius) Load torque with respect to motor shaft = (Aforesaid torque) divided by {(Gear box ratio) x (Drive efficiency as a fraction of 1)}. Conveyor is composed of linear motion and rotary motion components.

Frequency domain characterization of torque in tumbling

By means of a flange type torque sensor, the torque signal is recorded when the motor is driving a constant torque load, (Fig. 1 (a)), and a ball mill, (Fig. 1 (b)). The presence of an oscillating component of around ± 2 Nm, superimposed to the average value, can be observed in the case of constant torque load.

BALL & ACME LEAD SCREW TECHNICAL INFORMATION I

the performance of ball screws is far superior. The rolling action of the balls versus the sliding action of the ACME nut provides significant advantages. Advantages of ball screw drives are increased efficiency (typically up to 90 – 95%) which allows required motor torque to be lower, predictable service life, low wear rate and maintenance
