Unlike the ball mill work index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test. Plotting the database of global projects shows some relationship (Figure 5), but is still very much ore-dependent.

Hammermill Crushers

Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

Ball Mills

Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ore processing system .

How it Works: Crushers, Grinding Mills and Pulverizers

Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.

Crushing and Grinding Wet & Sticky Ore

In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high …

Gold Recovery And How To Choose The Right Process

Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.
