jun 01, 2003 the optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. for the dry powders used in pyrotechnics, the optimum speed will be 65% of the critical speed. using this rotation speed calculator will help you determine the optimal speed for your mill without having to reach for a calculator.

for overflow ball mills, the charge should not exceed 45% of the mill volume for grate discharge mills, the charge should occupy about 50% of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, he, and the radius of the mill, i.e

where b.max is the maximum size of feed is compression strength is modulus of elasticity is density of material of balls is inner diameter of the mill body generally, a maximum allowed ball size is situated in the range from to the degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

pyro ball mill speed calculation. milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material

the calculator will automatically provide the necessary speed and feed in the green fields. for assistance setting up your milling program, contact a dapra applications specialist or call 344. click here to download a chart of recommended ball nose cutting speeds and feeds

example: using the same criteria as the spindle speed calculation, rpm 6037; from the chart, chip thickness is 0.005 and all of our ball nose finishers have flutes. i.e.- 6037 0.005 60.37 ipm; your feedrate can be calculated by the formula: rpm chip thickness of flutes. calculate De effective cutting
