Effects of slurry filling and mill speed on the net power

The Wits pilot mill (552 × 400 mm), initially loaded with 10 mm balls at 20% volumetric filling, was run at 5 different speeds between 65% and 85% of critical. The net power draw and media charge position were measured. After this, the slurried ore was gradually added to the media charge for slurry filling U between 0 and 3. A proximity probe

Effects of slurry concentration and powder filling on the

Abstract The tests covered a range of slurry concentrations from 30 to 55 vol.% solid and fractional interstitial bed filling ( U ) from 0.3 to 1.75, at a fixed ball load (30% of mill volume) and 70% of critical speed, using batch grinding of a feed of −30 mesh (0.6 mm) quartz. At a fixed slurry concentration, the net mill power versus U went through a maximum, and both the optimum value of

Optimization of mill performance by using

2015-4-16  Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration.

How phosphate is mined and processed

2014-4-21  The fast movement of the slurry causes it to bang against the pipes, and this breaks apart any clay balls. What arrives at the beneficiation plant are fine-grained sand, clay and phosphate sediments suspended in water. At the beneficiation plant, the slurry is first run through a screen, which filters out the coarser sand.
