What it is the optimun speed for a ball mill,
Calculation of optimum speed depends on knowing the media diameter and jar I.D. also. For instance, if your jar had in inside diameter of 90 mm and your milling media was 12.7 mm diameter lead balls, the optimum rotation would be 98 RPM. Optimum RPM= .65 x Critical speedwhat is theoptimum rotation speed for a ball mill,Vs5080 High Precision 5 Axis Cnc Milling Machine Center Price , Find Complete Details,Ball Screw Bearing:,operation at low speed and guarantees stable rotation during operating at high speed so as to enable wider machining range.,Optimal extension ratio of spindle box realizes the optimal machining rigidity.

No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
