How can one select ball size in ball milling and how much
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.
