Learn More10/21 · 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

Learn MoreBut 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)

Learn MoreBy 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.

Learn Morethe 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
