The pebble stockpile material is fed to one or both of the cone crushers which discharge onto the SAG feed belt. The SAG trommel undersize flows into a common sump shar ed with the ball mill.
SAG milling, the most widely used and energy consumer stage in the grinding circuit, acquires a very important role. Usually, tumbling mills power equations have been derivate ... all the same discharge system, resulting in a lower variation in the effect of the slurry pooling on power (Moys et al., 1996). As an

Developments in SAG Mill Design and Operation Over the last few years, SAG mill manufacturing technology has advanced rapidly. The bounds of mill size have been pushed from two directions. Firstly, the advent of ring motors has removed the ...
Pulp lifters, also known, as pan lifters are an integral part of the majority of autogenous (AG), semi-autogenous (SAG) and grate discharge ball mills. The performance of the pulp lifters in conjunction with grate design determines the ultimate flow capacity of these mills.
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
Improved Relationships for Discharge in SAG/AG Mills. Ceramic ball wear prediction in tumbling mills as a. The aim was to study ball size variations throughout the cycles. Traditionally, mill media wear rate is evaluated by measuring the media level in the mill, or by removing media charge and weighing it after a certain number of hours ...
SINGLE STAGE SAG/AG MILLING DESIGNOrway Mineral . SINGLE STAGE SAG/AG MILLING DESIGN ABSTRACT Single stage semi-autogenous / autogenous (S/AG) milling has become a common design for a variety of ore xPebble extraction rates and discharge designs in the pilot mills.
Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400-500%.

This is the third review of SAG milling practice in Australia, previous surveys were presented in 1991 (Siddall and White) and in 1997 (Siddall). ... circuiting of the SAG mill and ball mill additions topping the list.
I've got to explain this a little bit. This flowsheet is typical of lines 1 and 3. The SAG mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the ...
MATERIAL TRANSPORT IN AG/SAG MILLS Generally the discharge from AG/SAG mills consists of one or both of the following two components: • Slurry – water and finer particles generally smaller than 12mm, and • Pebbles – 20-100mm. The type of grinding circuit and the typical mill discharge are given below in …
