Tips for Selecting a Lubricant for Ball Screws Design World

Jan 14, 2010Speeds that are high for ball screws are no problem for grease, so speed is not a criterion for selection. For example, grease is the accepted lubricant for machine tool spindles with dn (bearing bore, mm x rpm) values as high as 1,000,000. For ball screws, dn values rarely exceed 100,000.

Rod mills, how they function mine-engineer

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
