Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.

The rod mill can be used for both dry and wet operation, and peripheral discharge can also be used for wet grinding. Overflow Rod Mill. Ore discharge refers to the rod mill that the ore is discharged by the ore pulp itself. Unlike the overflow ball mill, which has no neck of hollow shaft at the discharge port, ...

The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.

Autogenous Grinding (AG) Mill. Wet or dry; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed; High capacity (short retention time) ... SSR Mill (Svedala Rubber Roller mill) Wet or dry; …

Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.

Shi (2016) developed a mechanistic overfilling indicator for wet overflow ball mills based on the slurry residence time inside the mill. The methodology determines the overfilling threshold using ...

A worked example shows how the new ball mill scale-up procedure is executed. This worked example uses laboratory data to predict the performance of a full-scale re-grind mill circuit. This circuit consists of a ball mill in closed circuit with hydrocyclones. The full-scale ball mill has a diameter (inside liners) of 1.85m.

The types of mill normally encountered can further be classified according to the method of feeding the raw material to, and the removal of the final product from the mill. These classes are: Batch mills. Grate discharge mills. Trunnion overflow mills. Air-swept mills. The principles of these mills are illustrated in Fig. 1.4 and Fig. 1.5 ...
