For example, liner wear can greatly affect SAG mill performance (Toor et al., 2015) and simply including the entire historical dataset might not be optimised to predict SAG mill performance. This ...
Unlike traditional mills that rely on steel balls or other media to break down materials, SAG mills use their own weight and the force of material being fed into them to grind ores. This makes them more energy-efficient than other types of machines. SAG mills are typically large cylinders made from steel with a rotating drum inside.
ball mill circuit can consume the same weight in steel used to ... Emphasizing that no two mill liner applications are identical, ... to ensure that the final solution delivers optimal results." Hearn concluded by saying that "the traditional use of steel liners in large SAG mills presents challenges. For instance,

Outotec Poly-Met mill linings combine the most desirable properties of rubber and steel to maximum advantage. This combination allows the use of more wear resistant alloys of iron and steel than can be used in a conventional metallic lining, as the rubber substantially dampens the impact forces and also results in a lower lining weight. This
Figure 2: Cascading-impact action in a SAG mill. Rubber and composite mill lining systems. In the past, grinding mills were typically lined with cast metal linings of varying steel or iron alloys, and lining system selection was typically driven by level of wear protection and cost. As materials technology and design technique has advanced ...

Key considerations for liner design include lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity.
In the work, as an object of modeling, we selected mill type MSHTS 5500 × 6500, used for grinding apatite-nepheline ore, with the following technical characteristics: mill capacity Q = 300–310 t/h, drum diameter without lining D = 5500 mm, drum length L = 6500 mm, the working volume of the mill V = 140 m 3, ball loading m = 275–285 tons ...
Dramatic shortcomings of mill liner designs, especially of large SAG mills, - such as rapid failure and ... They are light in weight and make use of the grinding media hardness to provide an effective wear material. They need to be manufactured in Manganese steel to wedge the steel balls, but the manganese steel spreads on impact and can make ...
The EMAT sensors are attached to the bolts holding the SAG mill liner and send measurements to a base station at regular intervals or on-demand, to inform the operators of the conditions of the liner without having to stop the mill. Features. Continuous measurement of up to 8 points on the SAG liner with one instrument. Accuracy within …
Example: a 26' ø × 11' EGL SAG mill with a 6" effective thickness polymet liner might draw 2,917 kW whereas as a 4.5" effective thickness steel liner might draw 2,991 kW. If you know the power draw and effective thickness of your current liners, use the ratio of (diam new / diam old)^2.5 to get a rough estimate the multiplier (for the same ...
SAG mills are typically operated at a constant speed, with the feed rate controlled by the mill weight. The mill weight is measured by load cells or a strain gauge, and the controller adjusts the feed rate accordingly. SAG mills can be operated in open or closed circuit, depending on the downstream process requirements. Maintenance of a SAG Mill

Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, which directly …
