How to Handle the Charge Volume of a Ball Mill or Rod Mill

In physics, the advise of a size is frequently pictorial by a share determined the advise blindness or the advise division. When the electric foundation that arises from the advise division exhibits a sizetric interrelation, a dexterous conformity public as Gauss's Law may be used to estimate the advise division of the size. The advise size of a sphere or rod mill is explicit as the percentage of the size amid the liners industrious delay spheres or rods. When the mill is fixed, the advise size can be quickly obtained by measuring the transection internally the liners and the removal from the top of the mill internally the liners to the top of the advise. The percentage loading or substitute size can then be learn off the graph in Figure 3 or can be approximated from the subjoined equation: % loading = 113 – 126 H/ D where H is removal from top of mill internally of lining to top of advise and D is transection of mill. Maximum capability is drawn by a mill when the advise occupies almost 50% by size. However, as seen in Figure 4, the capability incurvation becomes very vapid in the dispose aloft 45%. As a development, mills are infrequently run delay advise planes senior than 45%. In rod mills, the advise is protuberant by particles of pamper which severed the rods. If the mill is preclude down instantly behind the pamper is preclude off, the advise plane gain be senior than if the mill had been “foundation out” preceding to precludedown. Because of this, rod mills are normally operated delay a 32 to 40 percent advise by size. In exercise, this becomes a 40 to 50 percent advise, delay a size blindness considerably inferior than that of stacked rods. Ball mill advise becomes measurably protuberant solely when there is a buildup of wide unfoundation symbolical in the sphere mill or when the blindness of the meat in a wet mill is greatly exalted. Although these provisions are infrequently encountered, it is recommended that sphere mills be foundation out preceding to precludedown for configuration of the advise plane.
