Although rod mill installations are thus restricted in normal practice to the coarse crushing of soft and friable ores, it is sometimes found that the most economical method of grinding an ore of not more than average hardness is to use a rod mill in the primary and a ball mill in the secondary stage.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Autogenous and semi-autogenous mills are designed for grinding or primary crushed ore and are the most widely used in concentrators globally. Ball mills Ball mills are typically used for secondary and/or tertiary grinding to prepare the material for downstream concentration processes. Rod mills Rod mills are mainly used for primary grinding of

AG/SAG mills are normally used to grind run-offmine ore or primary crusher product. Feed size to the mill is limited to that size which can be practically conveyed and introduced into the mill. The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a ball mill, pebble mill, or
Can a ball mill be used as a primary crusher? The answer is relative to the 'particle'' size, the type of mill and the mill 'media' (like steel balls, ceramics, abrasive pastes, etc).

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters. Rod Mill-Ball Mill Circuits Diagrams of mill circuits [image: (135-8-2)]
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
Even though production was dramatically improved, the product size of the secondary ball milling was reduced and recovery increased. The results in SAG-Mill line 2 are even more dramatic. Because of segregation on the coarse feed stockpile, SAG-mill 2 receives a higher percentage of coarse material.
