mar 20 2017· mathematics of grinding critical speed:the "critical speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface.this is the rotational speed where balls will not fall away from the mill's shell. mills are driven in practice at speeds of 5090% of critical speed the choice being influenced by economic
this extra strength besides eliminating the possibility of head breakage or other structural failure either while in transit or while in service imparts to ballrod mills a flexibility heretofore lacking in grinding mills. also for instance if you have a 5 x 5 mill you can
other established methods for instance hardgrove index population balance. scale up in sizing for grinding mills scaleup criterion is the net specific power consumption i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids.
note:grinding balls and media are sold on a per pound basis but attritors and dmqxmills are loaded by volume. therefore the more dense the media the more pounds of media required. for instance a machine requiring only 40 lbs. of stainless steel may require up to 80 lbs. of tungsten carbide.
