Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

A coneshaped discharge of 20°30° reduced angle usually produces optimum conditions for separation. Cyclone control is best obtained by optimising the feed density. With consistent ore types the cyclone feed density is a good indicator of cyclone overflow sizing. A ropy cyclone underflow indicates a very highdensity state with a risk of ...

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...

A grinding mill needs a classifier to extract the particles that have been milled sufficiently finely, and to send oversize particles back to the mill for further grinding. A cyclone does this, with the cyclone overflow being the mill final product, and the underflow reporting back to the mill feed. ... Location: Water dam dredging, Sand mining ...
