SAG mill optimization insights by measuring inside the mill
A further attempt to measure inside the mill was detailed by Martins in his doctoral thesis at McGill University Montreal, Quebec. Martins presented the study of an instrumented ball, a camera system and a DEM analysis to propose mill entropy measurement. The system was successful in laboratory scale with wood and plastic as the mill charge.

The sag mill feed conveyor was fitted with an on-liner to the stockpile must be treated through the ag/sag mill. Hence for sizer using image analysis, whilst the stockpile had an ultra-sonic longer term gains the feed size going on to the stockpile must be indicator which tracked its level down to a certain point below which modified. excessive
AG Mill and SAG Mill - ball mills supplier
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. The ore larger than 100mm in the AG mill plays the role of grinding medium.
Optimizing your SAG mill operation - International Mining
In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.
SAG Mill - goldcilplant
SAG mill can be applied as the first stage grinding equipment. It can effectively avoid the occurrence of sliming phenomenon, and avoid further grinding of fine particles. It can play a good role in controlling granularity and energy saving. Advantage of SAG Mill Infrastructure investment and equipment cost is lower than common process;

SAG Mill Liner Types - MGS Casting
As an example at the Kalgoorlie Consolidated Gold 2Mines (WA) 36ft SAG mill the variety of Outer Head Liners was reduced from 36 to 18 items and in doing so decreased the time to replace them by 9 hours at an expense downtime saving of regarding U$ 25,000 per hr. In this instance the liners areas are 3.5 t each.
Electronic ear in SAG mill - Automation & Control Engineering Forum
We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 4-20mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.

The mill's SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original 12 x 28-ft single-deck SAG mill discharge screen.
