Ball Mill Output Feed Size

How Ball Mill Ore Feed Size Affects Tonnage & …

The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. Even though the rod mill could be a relatively inefficient device for both energy and metal consumption, as was evidenced by Bond, it ...

Effect of Grinding Media on Milling

Thus, it follows that the expenditure of equal amounts of work produce practically identical products from the same feed, regardless of the density of the grinding media.) When the ball charge is fixed, variation of the quantity of ore in the mill brings about no significant selective grinding between the different sizes of material in the feed.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical
