May 28 2020 The feed samples of X Y and Z iron ores were ground in the BBM ball mill refers to a BBM of size 300 mm 300 mm with smooth liners to identify the PSD BWI and RT of each ore. Grinding experiments were conducted according to Bonds standard test procedure .For each iron ore sample the RT taken to produce 250 circulating load in the BBM was measured by a new method.
A 20Mta mill will have a capital cost within 10000 th and 20000 th Lane Fleay Reynolds amp; La Brooy 2002. Typical operating costs for mills used in gold extraction are summarized in Table 3. The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV.
When new the use of the turbo rotor can provide a product size of 97 -212 micron. Turbo rotors can be refurbished and dynamically balanced if they become worn. The 200 Lab Mill is used for crushing and many more materials in the medium hard range. Once the material is fed into the feed chute it quickly flows into the mill grinding chamber .
FLSmidth ball mills. Figure 1 - Overview grinding circuit The Copper Mountain SAG mill is 10363 mm 34 feet in diameter and 6096 mm 20 feet long. It is a grate discharge mill with an inside diameter of 10363 mm 34 feet and a grinding length of 5334 mm 17.5 feet. The mill is driven by two 8500 horsepower ABB motors.
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. citation needed But note that the term rod mill is also used as a synonym for a slitting mill which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

Rod Mill Operations. Designed to accept feed from a secondary crusher. Feed particle size 6 – 25 mm. Peripheral speed 85- 146 mmin 280 – 480ftm in Reduction ratio 2 – 20 depending on material. Typically R 8. Rod Mill Charge Typically 45 of internal volume; 35 – 65 range; Bed porosity typically 40.
Tumbling ball mills are capable of fine grinding to around 20 μm with the energy efficiency increasing with decreasing media size depending on the feed size. For feed sizes P 80 of 55 and 100 μm Partyka and Yan 15 showed an increased efficiency with decreasing steel ball size from 36 to 5.5 mm in a ball mill. At a larger feed size P 80 .
milling circuit consists of a rod mill followed by a ball mill in series. Crusher product -9 mm is fed to the rod mill and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped without any further water addition to the first ball mill. The ball mill discharges to a sump where water is
