Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent.

Ball/Rod mill Literature The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

These work indexes can be used for the determination of tumbling mills (rod, ball mills) power. Thus, the suitable mill dimensions can be effectively determined. Search Search

A ball mill is a type of grinder used to grind and blend 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.

work input and grindability for the ball mill using the above, standard method of dry grinding Traditional measurements of ore grindability are the Bond Work Index The Bond test, widely used for predictions of ball and rod mill energy

The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.

mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm. These ﬁ nes proceed to the ball mill improving the ball mill efﬁ ciency.

They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

As in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.

AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many applications.

A rod mill is a mill in which a grinding body is a steel rod. Rod mills are available in dry and wet versions, typically in a wet overflow type, which can be used as a Class 1 open-circuit grinding. The rod mill is mainly used in artificial

Ball Mill and Rod Mills Drives In all cases, except in a few laboratory sizes, ball and rod mills are driven by a pinion which is mounted on a counter-shaft and engages with a gear-wheel bolted to the shell.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5]
