SAG and AG Mill – Amstar Corporation

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Amstar SAG/AG Mills range in size from 4.3m

Choosing a SAG Mill to Achieve Design Performance

SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. Typical tests required to define a hardness variability function, are given below in Figure 1.

Difference Between Sag Mill vs Ball Mill

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is …

Selection of Comminution Circuits for Improved Efficiency

• Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of 0.5 to 2 Mt/a.

Throughput optimisation in milling circuits

SAG Mill Power SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change.

Influence of explosive energy on the strength of the rock …

 · Ignoring the additional benefit of finer fragmentation, the reduction in fragment strength alone should yield a 21.8% increase in SAG mill throughput, by blasting with PETN instead of Black Powder. This implies that initiating a change in blasting practice, through use of higher energy blasts, can reduce cost of crushing and grinding (more tonnes of ore can be crushed for the same running costs).
