The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of

or 45% corn DDGS ground at 450 microns using a roller mill, or 45% of corn DDGS not further ground (unprocessed) at 650 microns. Results show that particle size reduction either with a roller mill or a hammermill (from 650 to 450 microns) increased ATTD of GE and DM of corn DDGS, tended to increase ATTD of N, but had no effect on ATTD of NDF.

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and

· Mill roller shells are amongst the most important manufacturingline elements in the sugar production process. They are carefully designed according to many surface criteria amongst which wear resistance is the most important. To increase the life of the mill roller shells, the resistance of the surface to failure by abrasion should be increased.

Roller mills simply "roll" or "crush" product between two revolving cylinders. This latter process has the distinct advantage of requiring considerably less power, although it is not possible to achieve the fineness of final grind through a roller mill that can be achieved through a hammermill.

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form then, "continuous casting" has evolved to achieve improved yield, quality

If drill and blast costs need to be increased to improve the quality of fragmentation, these costs are far outweighed by the reduction in mill operating costs – typically 7 to 10 times any increase in mine costs. At the same time, the concentrator must be prepared to take advantage of the much improved, higher quality feed material.
