The ball grinding machine from Friedrich Fischer was PresseBox
After a long series of laborious and costly tests, metalworker and turner from Schweinfurt, Friedrich Fischer, succeeded for the first time in 1883, using his own invention the "ball grinding mill", in manufacturing large volumes of hardened steel balls, which were of equal size and perfectly round. 125 years ago, on July 17, 1980, Fischer Since the grinding ball attrition rate for a grinding mill is known, computer controller 90 can be programed to sequentially feed grinding balls, one-at-a-time, at the predetermined attrition rate. For example, controller 90 can be programed to feed a single ball at time intervals as short as about 20 seconds to as long as about 45 minutes.Apparatus for feeding grinding balls Google Patents
