What is a SAG mill The structure of the SAG mill semi-automatic grinding mill and the AG mill autogenous grinding millare 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.
Aug 19, 2019 Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more flexible when it comes to meeting ...
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol ...

Abstract Conventional mining process circuits use both Semi-Autogenous Grinding SAG and Ball mills. It is very common that the SAG mills are operated with adjustable frequency drives AFDs and the Ball mills are operated at fixed speed 1. Recently, however, adjustability of Ball mill speed has been given more consideration. Also, to ...
models were required for ball mills and AGSAG mills. This view w as perhaps driven by the fact that the early models were developed at a time when AGSAG mills were almost non-existent and hence these models simply considered the ball charge only, which, if these models were to be applied to ball mills only is not a n unreasonable assumption.

SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.
Apr 01, 2016 The slurry level in AGSAG and ball mills has an influence on their power draw, which in some instances can be profound. This is particularly the case with so-called slurry pooling in AGSAG mills which can result in significant lowering of power draw. From a predictive viewpoint there are currently no published models that explicitly describe ...
