sag mill feed size

Oct 12, 2017·SAG millmake use of steel balls included with some large and hard rocks for grinding. Thesemillsutilize the balls in making the large fragments of materials broken into pieces. The ball charge of aSAG millis about 9% to 20%.This process takes place inside the large rotating drum ofSAG millwhich is filled with balls partially.

Jan 01, 2016· Thefeedto high aspect AG/SAG millsare usually preferred from gyratory crushers, while thefeedto low aspectmillsare preferred from jaw crushers. Depending on the set, the maximumsizeof the particles discharged from gyratory crushers is about 300 mm and from jaw crushers is about 180–100 mm; thus, the optimumfeed sizemay be taken to ...

The traditional operation ofSAG millsrelies on the operator to adjust the manipulated variables to maintain the targetmillload and power draw. Changes to the ore hardness,feed sizeor ore specific gravity require an alert operator to adjust the variables while …

Some example transfer size ranges: Canadian Shield gold SAB operation, use500 µm to 1500 µm (typical target 800 µm) Porphyry copper SABC-A operation, use1000 µm to 3500 µm (typical target 2000 µm) Porphyry copper SABC-B use arange of 3000 µm to 7000 µm (greater pebble flow means you should use a coarser T 80).

AG/SAG millscan accomplish the samesizereduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of a ballmill. Because of the range ofmillsizes available, AG/SAGmilling can often be accomplished with fewer lines than in a conventional rodmill/ballmill…

Thefeed sizeis usually between 20-30mm and the productsizeis 0-3mm.Feed. Both the autogenous grindingmilland the ballmill feedparts are welded with groove and embedded inner wear-resistant lining plate. As thesag milldoes not contain grinding medium, …

Secondarymill feed– Continuous regulation capability gate to allow controlled distribution offeedbetween the two ballmills. Finally, if the amount of criticalsizematerial removed from themillis less than the crusher and secondarymillscapacities, thosemillscan also be fed with a small fraction of theSAG milltrommel undersize in ...

The capacity of theSAG millis related to lots of factors such asfeed size,sizedistribution, dischargesizeand grindability, etc., and it should be confirmed according to the actual situation. SM40*14’——means it is a drymill.
