Ball End Mills. They can also be used in a secondary way to form a radius at the juncture of perpendicular surfaces. A ball end mill will produce a radius one half the diameter of of the tool used. A square end mill with a radius ground on the corner can provide a small radius at the juncture if reduction of stress is the desired objective.
All Answers ( 4) If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls. There should be atleast 25% empty place in the milling jar after feeding balls and the material while high energy impact. There is no such thumb rule for powder to ball ratio.

The power predictions for ball mills typically use the following form of the Bond equation: = (−) where E is the energy (kilowatthours per metric or short ton) W is the work index measured in a laboratory ball mill (kilowatthours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel .

There, the effect of a trunnion magnet system on the ball mill was significant: Total mill feed remained essentially unchanged, averaging approximately 1,300 t/h; however, total mill power consumption dropped 8% from an average of 7,600 kW to 7,000 kW. The mill work index dropped 10% from an average of kWhr/T to 5 kWhr/T.
Ball/Rod mill Literature The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.
