talcum wet ball mill
May 24, 2016 In one mill 5000 lb. of pebbles are used to one ton of talc in a mill revolving for 5 to 7 hr. at 22 r.p.m. In roller mills, which are continuous in operation, equipped with air separation, when the talc is ground sufficiently fine it is automatically removed, so that the full crushing effect is continuously applied to the coarser material.
