Air swept ball mill system

perforated tubular member, liiters in said discharge chamber for showering ground material over mentioned perforated tubular member, a conduit arranged to conduct ground material from the periphery of mentioned discharge chamber to mentioned grinding space, and load handle means comprising a valve adjustable to handle the flow of material by means of said conduit.

Continuous grinding within a smaller wet ball mill

Within a ball mill having a discharge end wall plus a discharge trunnon, a grid spaced from said discharge end wall to form a discharge chamber in mentioned mill, a perforated tubular member extending from mentioned grid into said discharge trunnion and possessing an mperforate section extending coaxially through stated trunnion in radially spaced relation, implies for depositing insuiiiciently ground material discharged from said tubular member inside the outer end .of your space among mentioned trunnion and stated tubular member, a material returning helix arranged in-and extending via said space, a conduit connecting mentioned discharge chamber using the grin g space of mentioned mill, a valve arranged to restric ow of material from mentioned discharge chamber to saidconduit, and signifies for conducting into mentioned conduit material which can be returned into mentioned mill by stated helix, stated last meansbypassing mentioned valve.

Effects of grinding media shapes on load behaviour and mill energy in a dry ball mill

In a ball mill obtaining a discharge finish wall in addition to a discharge trunnion, a grid spaced from mentioned finish wall to define a discharge chamber in stated mill, a perforated tubular member extending from said grid by way of stated discharge chamber into said' discharge'trunnion and getting an im"- perforaie section extending by means of stated trunnion in coaxially spaced relation, suggests for depositing insufficiently ground material discharged from said tubular member within the outer end on the space involving 4said trunnion along with the imperforate -section of stated tubular member, a material returning helix arranged in said space, signifies for drawing a current of gaseous iirid via stated mill and out by means of said tubular member and means in said discharge chamber for lifting and showering materials therein over the perforated surface or said tubular member.
