Exploring ball size distribution in coal grinding mills

2014-5-1  The ball size distribution (BSD) in a mill is usually not known, as the measurement of the charge size distribution requires dumping the load and laboriously grading the balls into size classes. Fortunately we had one set of data as discussed below.

Ball mills for various applications Gebr. Pfeiffer

Our ball mills are perfectly suited for the preparation of hard and very abrasive materials. When operating on the open circuit principle, the product fineness and grain size distribution are adjusted via the peripheral material discharge. In case of circuit grinding, these parameters are set with the high efficiency separator.
