optimum choice of the make-up ball sizes for maximum

optimum choice of the make-up ball sizes for maximum

Sep 01, 2013 · For a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: (11) m k = d k u 4 − Δ − d k l 4 − Δ d max 4 − Δ − d min 4 − Δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained. Δ is a constant, which relates …

ball mills vs rod mills

ball mills vs rod mills

When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the

Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy
