Sag mill ball exploding

The prediction and monitoring of liner wear inside a SAG or Ball mill has traditionally been accomplished and confirmed by a number of different methods, many of which require people to enter the mill. ... checking for exploding mill balls and overhead hazards, making the mill safe for entry, posting a sentry, and reversing the cycle when done

    AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill

    What is the difference between a SAG mill and ball mill?

    SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44

    Mar 21, 2007 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

    I had the misfortune about 28 years ago to be inside what was then a very large (32 foot) SAG mill that had been ground out (!!) with a 5 ball charge. It was actually quiet at the start, but then the balls started exploding. Things were cast hemispheres, and they were blowing apart at the seams

    What's the Difference Between SAG Mill and Ball Mill

    Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
