How to calculate motor drive torque for ball screws
Drive torque is primarily influenced by the axial load on the screw and the screw’s lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force (drilling, punching, etc.), but also includes the force required to move the load. Since most ball screw assemblies use profiled guide

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

How is ball screw torque calculated? – handlebar-online.com
How is ball screw torque calculated? If you know the linear force applied to a ballscrew, then you can calculate the torque produced by backdriving the ballscrew. The calculation is based on converting the applied torque to the force acting on the ball bearing, and then calculating the linear vector component of the resultant force.

Calculating Torque With Examples
In calculations, torque is represented by the Greek letter tau: τ. Torque is a vector quantity, meaning it has both a direction and a magnitude. This is honestly one of the trickiest parts of working with torque because it is calculated using a vector product, which means you have to apply the right-hand rule.
