Dynamic Modeling and Simulation of SAG Mill Circuits with

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.

AG SAG Mill for Mineral Processing Wet Aerofall SAG

What is a SAG mill? The structure of the SAG mill (semi-automatic grinding mill) and the AG mill (autogenous grinding mill)are exactly the same, except that a certain proportion of auxiliary grinding media such as steel balls or steel rods are added as needed. During the process of the AG mill operation, some ores with diameters greater than 20mm but less than 80mm are not easily ground.

SAG mill liners

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.
