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
Ag and semiautogenous sag milling often combined with ball milling now dominate comminution circuit design with strong signs that high pressure grinding rolls hpgr are poised to make major inroads as alternatives to ag and sag mills in some applications bonds specific energy equations and rock characterisation
That in most agsag circuits they are operated in closed circuit with relatively large aperture trommelsscreens recirculating loads as a result are very low usually less than 25 particularly when compared to closed circuit ball mills 250 this means that
Aug 19 2019 hpgr wear vs conventional mills 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
Assuming your ore is agamenable 7 tph to 15 tph is a comfortably production average for a 13 x 45 ag mill a 13 x 6 sag mill has a reasonable range of 20 to 30 tph for gold ore sag amp ball mill duty 25 to 40 th for copper porphyry sag amp ball mill duty

Oct 19 2020 the sag mill has four output slots recipes can have 14 different outputs with different chances of obtaining those outputs uniquely the sag mill can use grinding balls made from various materials to increase energy efficiency resulting in higher processing speed increase bonus output chances and add a chance to double all output
Individual sections the sag section or ball mill section as an example table 1 presents agsag pilot plant data for an oxide gold ore although the overall wio is close to the bwi the calculated figures would suggest that the agsag mill is very inefficient while the ball mill is
In multistage abcsabc 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 pebblesrocks which are crushed and sent back to the mill
Search working of ball mill and sag mill to find your need liming mining and construction machinery is a how does a sag mill work xsm sag mill is a new grinding equipments which combines crushing and grinding of two functions
All cylindrical tumbling mills ag sag ball and rod mills feature cylindrical structural shells protected from abrasion by removable replaceable mill liners every tonne of mineral ore must be processed through the grinding mills

Polystl liners are composites of a special wear resistant steel and high pressure moulded rubber which are suitable for ag mills sag mills primary mills and ball mills with ball diameters 3 inches and larger learn more
The internal device of the ball mill grinds material into powderlike substances and can rotate continuously for optimal grinding and refinery production a sag mill is most often used in the mining fields particularly in the mining of precious metals such as gold copper silver and nickel
The working principle of the sag mill and ag mill is basically the same as the ball mill machine but the barrel diameter of the sag mill and ag mill is larger the raw ore enters the ag mill through the feeding inlet and the material is brought to a high place under the rotation of the barrel and then falls
Oct 12 2017 sag mill make use of steel balls included with some large and hard rocks for grinding these mills utilize the balls in making the large fragments of materials broken into pieces the ball charge of a sag mill is about 9 to 20this process takes place inside the large rotating drum of sag mill which is filled with balls partially
