SAG mills mimic the same shortcoming. It follows that in order to obtain the specifi c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an ineffi ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.

What's the Difference Between SAG Mill and Ball Mill ...

26.11.2019  The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.

Mill (grinding) - Wikipedia

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusherfor mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with di

Modelling: Transfer size limits - SAGMILLING.COM

The model assumes all SAG mills are variable-speed; if a fixed-speed mill encounters this condition, it will completely grind out and operators will probably be forced to stop the SAG mill. Pick your mills sizes to avoid secondary mill limited conditions. This transfer size is NOT a prediction . This is the transfer size you must design the circuit to achieve in order for the

(PDF) Influence of feed size on AG / SAG mill performance

When the feed size of a SAG mill becomes coarser, i.e. α r increases, the energy required to break the ore increases, i.e. φ r and φ f increases (Morrell et al., 1996; Morrell and Valery, 2001 ...
