This is the simplest form of feeder consisting of a cylindrical or elliptical chute supported independent of the mill and projecting directly into the trunnion liner. This permits a continuous flow of material into the mill and reduces maintenance compared to other types. This feeder provides maximum feed capacity to a mill.
اقرأ أكثرThe calculations indicate that in order to obtain overload with smaller mills at a constant circulating load, the L/D ratios would have to increase progressively from the initial 1.2/1 value for a 5.5 n diameter mill, to a 6.8/1 L/D value for a throughput reduction to 10 percent of the original value.
