Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents. SAG mills generate higher levels of impact reduction and ...

By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ballmill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebblecrushing circuit product to the ballmill sump for secondary milling: while convenient, this has the ...

For 60 mm (″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately D in meters (for D in feet, divide D by ). Wave height above the liners from to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.

mentioned some case studies of using good liner designs. For example, the initial SAG mill liner was installed using HiHi with a 6. o . contact angle. Mill throughput increased by 11% after the face angle had been altered to a 17. o. angle and then to a 30. o. angle. Currently, the large face angle (typically 20. o . up to 30. o

Low weight with long wear life. 's Skega PolyMet™ mill linings combine the most desirable properties of rubber and steel to maximum advantage. This combination allows the use of more wearresistant alloys of iron and steel than can be used in a conventional metallic lining, as the rubber substantially dampens the impact forces and also ...

Ball Mill Design The ball mill designs also follow the Bond/Rowlings method with comparison with other methods. Again the method of use is the same SAG/BM Combined design This is the combined model of the SAG and BM models. The difference is that a provision in the BM model allows for the fact that finished product is in the BM feed.

Dramatic shortcomings of mill liner designs, especially of large SAG mills, such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life have highlighted the significance of correct mill liner selection.

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 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
