SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been ...

SAG mill energy required according to this statement, is 2.5 times more than the Ab value to produce the same degree of particle breakage. There is a speci fi c gravity factor that affects AG/SAG power draw. The lighter material, in the 2.5 specifi c gravity (SG) range, will require more energy to grind to the same transfer size than an ore with a 3.5 SG. This fact is not evident in the ...

operating SAG mills (it is not intended for design, but could help with it). Even if the mill total load is a key variable and can be indi-rectly measured with bearing pressure measurements, it was decided to discard it as an input variable.

Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible.

The current practice of exploratory design of ore pre-treatment process increasingly uses laboratory testing of ore strength, which allows simple and inexpensive but reliable ranging of crushing and milling machines [2].

The first step in mill design is to determine the power needed to produce the desired grind in the chosen ore. The most used equation, for this purpose, is the empirical Bond equation (Bond, 1960, 1961; Rowland and Kjos, 1978). In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and ...
