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 ...
Modelling and simulation of semi-autogenous (SAG) mills are valuable tools for helping to design control laws for a given application and subsequently to optimise its performance and process control. SAG mills (see Figure 1) are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their advantages such as higher processing capacity, …

Applications: It is commonly used in the mineral processing industry and ferrous and non-ferrous metal ore and nonmetal ore processing plants. It can also be used in cement plant, refractory plant, fertilizer plant and smelting plant.
SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of ...
SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load …
Features. Semi-autogenous Metso Outotec SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
AG/SAG Mill Liners. We have supplied rubber pulp lifters for SAG mills up to 40 ft in diameter. We are pioneers in the design of both radial and curved pulp lifters, also design and manufacture Rubber / PolyStl™ grates and discharge systems. Mining.
This paper describes the function and operation of lubrication systems for Ball Mill and SAG Mill Drives. Provided within this paper are hydraulic schematics, functional description and a general overview of system layout as well as some of the important features and factors relevant to improving the reliability of this very critical part of the grinding mill drive system. …
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is …

As a result, ABB developed three of the largest diameter and most powerful drive systems for a SAG and two ball mills installed at the highest altitude to date. The fully integrated and optimized solution for the grinding circuit consists of: 1 x 28 MW GMD to power the 40 ft SAG mill. 2 x 22 MW GMDs to power two 28 ft ball mills.
The SAG mill has a mill diameter of 24 ft (7.3 m) and an effective grinding length of 18.5 ft and a structural charge mass of 315 t, Condor Gold said. The structural design ball charge is 11% with a structural design load volume of 35%. Specific gravity of the material is 2.55.
Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
Effective SAG mill control will maximise throughput, minimise damage to mill internals (liners and lifters) and contribute significantly to achieving maximum recovery in flotation. Well designed and implemented SAG control will payback in weeks not years. SAG mill control is essentially the stabilisation of mill load (and/or power) and density
The various options available for large-horsepower semiautogenous grinding (SAG) mill drive systems are examined, together with their impacts on mill design and relative capital and operational costs.
