AG SAG Mill for Mineral Processing Wet Aerofall SAG

AG Mill and SAG Mill Details. AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding.

SAG mills TON Outotec

Semi-autogenous TON 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.

SAG Mill Process Control Grinding Classification

2021. 7. 15.  If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to what the shaft can supply.

SAG Mill Grinding Circuit Design

2016. 6. 6.  AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling.
