In terms of breakage mechanisms, while abrasion and impact prevail in ball mills, rod mills are used for their type of preferential grinding over larger particles . In general, in the milling stage, in order to avoid the generation of finer particles, the most desirable effect should be impact and compression, rather abrasion and shear, as ...

Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least Tube Mills. Tube mills are in principle to be considered as ball mills, the basic difference being that the length/diameter ratio is greater (3—5). They are commonly used for ...

In some cases, rod mill can replace short head cone crusher and do finely grinding. When dealing with softer or ore that is not too hard (especially the ore is with big viscosity), rod milling will grind the ore from 1925 mm (or even 32 mm) to 610 mm, with lower cost and a simpler device compared with short head cone crusher.

Dry ROD MILL Grinding. No other type of mill is so well adapted to dry grinding materials to 4 or 8 mesh in single pass with the production of a minimum amount of fines. A major factor in dry grinding is the rapid removal of finished material to prevent cushioning of the rods. This is accomplished in the End Peripheral Discharge Rod Mill.

Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...
