How many balls for the mill? - Tools and Tooling - Forum
From a litre point of view, approx 512 x 12mm balls will fit into 1L of space. If the mill isnt powerful enough to turn it you need a bigger motor, no sense dropping the media charge to accomodate a weak motor. The other option is to use a smaller jar with less media..that way the efficiency doesnt suffer Edited by Col, 15 January 2015 - 05:40 PM.
