In ball mill, ball has to be charged around 30-32% in first and second compartments. Balls are in the range of 50-90mm in coarse and 15-50mm in fine grinding. Grinding of material takes place by means of collision or attrition or tumbling action takes place between the balls and the charge. ...
The oligomerisation of l-amino acids by papain was studied in a mixer ball mill and in a planetary ball mill. The biocatalyst proved stable under the ball milling conditions providing the corresponding oligopeptides in good to excellent yields and with a variable degree of polymerisation. Both parameters wer 7th EuCheMS Chemistry Congress – Molecular frontiers and global challenges

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
Lead dust can become airborne due to improper air flow or exhaust ventilation, which results in puffing of lead oxide at the mill inlet. Exposure may occur from handling lead pigs while loading the mill pots or the ball mill. Lead oxide dust may spill or leak from trunnion seals, bearing seals, conveying systems, and transfer points.
