The forces against a frac plug during the frac is equal to (up to) 10,000 psi times the area of the casing ID. For 5.5" 20# casing this can be up to 200,000 lbs. When milling out the weight on the bit can be up to 10,000 lbs, much less than what the slips are designed to handle.
Ball Mills - Mine Engineer
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
