A new Geoscience centrifugal ball mill was used to mill various batches of 238 PU02 for varying time intervals. To attain simi-lar particle size reductions with this mill, shorter milling times were anticipated be-cause of higher rate of energy input. Mill-ing was carried out using a carrier liquid which was expected to reduce agglomeration.
Two. Ball mill is easy to throw out pulp through throat. During the normal ball milling process, pulp is thrown out from throat with small stones.
