Energy Consumption in Mining Comminution
2.1 Energy Consumption in Open Pit/ Underground Mines There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where

Failure analysis of a steel slide ring of a tubular ball
This work identified the root cause of an early failure occurring near welded joints that connect the slide ring with the head of a ball mill used in an iron mining plant. The ASTM-A516-G60 steel specified for use at this location had a lower carbon content than required.

26-06-2012A ball mill at the old White Pine mine. This was one of many attempts to make mining the Nonesuch Shale pay -- a bed of sandstone with extremely fine copper embedded in it. The Nonesuch mine (in the Porcupine Mountains) was the first attempt, with the old White Pine coming again later. It took quite a long time -- until the 1950's! -- for the Copper Range Company to solve the problem (at
Energy Use of Fine Grinding in Mineral Processing
18-12-2013The smallest ball size typically charged into ball mills and tower mills is inch (12.5 mm), although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al .,[ 7 ] a GIS mill charged with 5-mm steel shot, and with other operating conditions similarly optimized, achieved high energy efficiencies when grinding to less than 20 μ m.

Energy and Cost Comparisons of HPGR
To determine whether the novel HPGR-stirred mill circuit arrangement could achieve energy savings in comparison to conventional SAG mill-based circuits, a pilot-scale study was conducted to compare the energy requirements of the existing circuit at the Huckleberry mine to two alternative circuits: an HPGR-ball mill circuit and a novel HPGR-stirred mill circuit.

The Rosebery crushing circuit consists of a Primary Jaw Crusher and a Secondary Cone Crusher. During Crushing the ore size is reduced from around 650mm to P80 of 20mm. The Grinding Circuit consists of 2 x Primary Ball Mills and 3 x Secondary Ball Mills.
Ball Mills
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
