Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with …
With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to 2.5) for a coarse mill feed (say F80 > 110 mm). If the mill feed size is fine, say 50 mm or 30 mm, then you are looking at a total charge to ball charge ratio of about 1.5-1.6. These are guidelines and may fluctuate a bit depending on the ...
The SAG Mill has a "small" circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is "good" but un-measured. SAG Ball consumption is …
It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't possess a single hardness. The existence of this variance is what causes ...

When the mill runs, the grinding ball is falling from the high position, and tooking big impact force. if the material and manufacturing qulity is not well, the SAG mill grinding media is easy broken. In ZJH minerals, we always adopt the high quality forged balls to avoid the breakage of the grinding ball. Some cases of grinding media for SAG ...
SAG and Ball Mill Liner system serves two purposes: Protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action. To achieve this, the mill liner profile must be constructed from high wear resistant materials and incorporate correct geometry to …

Today's mining operations must keep crucial milling assets online and running optimally, but variations in ore particle size, feed rate and moisture content, can lead to plugging, high vibration and machine bearing wear, and ...
The SAG Mill has a "small" circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is "good" but un-measured. SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing ...
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
