feed rate of a gold ball mill

how to size a ball mill -design calculator & formula

where n is the number of efficiency factors, efi, used and fo is the feed rate of new ore to the mill. the power calculated from equation 2 can be looked up in published tables (rowland and kjos, 1978) and the correct mill size and type can be selected.

for external adjustment, the feed rate must be increased due to less tool engagement. take this example, in which a harvey tool threadmill #70094, with a .370” cutter diameter, is machining a 9/16-18 internal thread in 17-4 stainless steel. the calculated speed

understanding cnc cutting tool speeds & feeds - destiny

other terminology such as feed rate (ipm) and rpm are variables based upon diameter and therefore of little use other than to calculate sfm and ipt the phrase " speeds and feeds" (or " feeds and speeds" ) refers to two separate velocities in machine tool practice: cutting speed and feed rate .
