A new large concentrator unit typically consists of a semi-autogenous grinding mill, high pressure grinding rolls, two ball mills, and a flotation circuit. It can treat up to 170 000 tonnes of ore per day ( Sartain, 2010 ). Larger concentrators consist of multiples of this basic concentrating unit.
Difference Between Sag Mill vs Ball Mill
Semi-Autogenous Grinding Mill – SAG Mill: SAG is the abbreviated form for Semi-Autogenous Grinding Mill. This type of Mill is used for grinding large fragments into small pieces. Pieces are then used for further processing. The SAG mills are generally used in pre-processing of any type of material in grinding process.

Wet or dry; Higher capacity than A-G mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) Semi-Autogenous Mill
Semi-autogenous Grinders – VIRIDIS Engineering
Semi-autogenous Grinder (SAG) utilizes grinding balls like a ball mill. A SAG mill is usually a primary or first stage in the grinding process. SAG mills are characterized by their large diameter and short length as compared to ball mills.
SAG Mill | Autogenous and Semi-Autogenous Mills
Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in ...
Dynamic Model of Semi-autogenous (SAG) Mill System
Dynamic Model of Semi-autogenous (SAG) Mill System Abstract: In this paper, the dynamic mathematical model of semi-autogenous (SAG) mill system is studied through the experimental investigation and rational analysis on the basis of the actual situation in SAG mill factories.
What's the Difference Between SAG Mill and Ball Mill
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. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
