Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (, increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

The Borrowdale graphite mine increased in importance as demand grew, and the price of high quality graphite increasing from 18 pounds per ton in 1646 to 3920 pounds in 1804. This price rise led to considerable problems of theft,thus in 1752 an Act of Parliament was passed making unlawful entry into a graphite mine a crime.

CIL (Carbon In Leach) is the carbon leaching method for gold extraction. Normally the CIL process can concentrate gold from g/t in ore to 2000 to 6000 g/t on carbon. CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content. It is characterized by low cost, short infrastructure construction time and few production links.

In this case the grinding circuit comprises an open circuit rod mill followed by a closedcircuit ball mill. The ball mill is most often closed over a classifier like a hydro cyclone (Fig. ) or DSM style screen with a fine cut of mm. The course material is returned to the ball mill feed and the fine screen underflow reports to the ...

The power draw is driven mainly by mill diameter and length, ball and slurry charge level, and rotational speed. But the slurry charge in an overflow ball mill doesn't change very much because most of the slurry occupies the void space in between the balls, so as the circulating load increases, the discharge rate also increases.
