    Tips for Selecting a Lubricant for Ball Screws

    Ball nut operating temperature should be approximately 20C, but this is seldom the case in real operation. Usually, a ball nut stabilizes a few degrees above screw shaft operating temperature. If you can't measure nut temperature, assume it to be 30C for your initial selection of oil viscosity. Required oil flow rate is a function of:

    How Many Balls in a Ball Mill?

    In general, the ball volume of the ball mill steel ball is lower than the horizontal line in the cylinder. It is better to control the ball amount at about 40-50%. For smaller ball mills, the ball balls accounts about 35% at best, this can effectively ensure that the steel ball can fall freely, so that creates a larger impact force.
