Ball Mill Design/Power Calculation

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Thread Mills

Thread mills differ from taps, because they have a smaller diameter than the thread size produced.The thread mill cutter must be able to enter the drilled hole, and then interpolate the thread profile. Because offset adjustments can be used to compensate for tool wear – as long as the thread form is still good – thread mills typically produce more threaded …
