AG & SAG Mill- Semi Autogenous Grinder
The most important feature of AG mill or SAG mill is to feed raw ore from the stope or after crushing the ore to the mill directly. Typically certain mineral grain size ratio to the mill or rod mill. Since AG mill or SAG mill can grind the material to -0.074mm (its content once accounted for more than 20% to 50% of the total product).
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 ...
BrainWave: Control solutions for SAG mills
The solution: Measure. Control. And profit. BrainWave SAG mill is a unique control package using patented model-based predictive adaptive control technology. It is well known within the mining industry that efective grinding in a SAG mill depends largely on the loading of the mill. A mill con-taining too much material does not allow for ...
Optimizing your SAG Mill | Mining Surplus
As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.

Understanding the SAG Mill in Copper Ore Mining Process
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...
Semi-Autogenous Mill (SAG Mill) | 3D CAD Model Library
October 14th, 2013. An AG mill is a tumbling mill that utilises the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media. An SAG mill is an autogenous mill that utilises steel balls in addition to the natural grinding media (Wills' Mineral Processing Technology, B.A. Wills, 6th Edition).
Measuring charge motion from inside an operating SAG mill …
This paper reflects on how measurements from inside an operating SAG mill might be used to better understand charge motion and energy dissipation within the mill. The paper discusses how the measurements might influence and enhance approaches to energy efficient mill operation when compared with current day modelling techniques. Insights …
Semi-Autogeonous (SAG) Mill Overload Forecasting
1 Introduction. In mining, a Semi-Autogenous Grinding mill (SAG) is the equipment used at mineral processing plants in the size reduction process, making the ore suitable for the next stage of flotation. Its use lies in significant processing and reduction capability offered by this kind of mill, where maximize the operational continuity and ...

Unlock SAG mill capacity with process control optimisation
The instrumentation installed on a SAG mill is integral to control. For example, the mill load and noise sensors are instruments that provide essential information for an optimized SAG mill operation. Insufficient understanding of the ore characteristics and feed composition can result in an ineffective SAG mill operation.

NAVACHAB CIRCUIT. The circuit consists of a single-stage, low aspect ratio (diameter:length = 0.5) mill, typical of the majority of SAG mills in the South African gold mining industry. These are locally known as run-of-mine, RoM, mills. The mill is operated at 90% of critical speed and with a volumetric load of 40%.
Choosing a SAG Mill to Achieve Design Performance
It is an approximation or a best guess based on limited data. This equation is: y = 225 – 1.94 x (1) Where x = the load in the mill expressed as measured % by volume and y = kg/h of feed. This information is based on observed throughput reductions caused by loading the 3-ft. SAG mill to over 26% by volume.
