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

911metallurgist-SAG Mill Liner Design - Free download as PDF File (.pdf), Text File (.txt) or read online for free. SAG mill liner design and configuration can significantly impact mill performance. Key considerations for liner design include lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity.

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.

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 …

Depending on your goals and application, we offer a range of premium composite and rubber mill lining solutions for rod, ball, AG and SAG mills. Rubber mill lining is predominately used for smaller secondary and tertiary ball milling (regrind), whereas our composite mill liners (made from one or more materials) are used for heavy-duty …

The Morrell C-model is generally regarded as one of the most accurate tumbling mill power-draw models and is ideally suited for this application of estimating fill levels of the SAG mill in real time.

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 ...
