Question 2(40 marks)In an Iron Ore concentrator, Iron ore fines are fed to a cyclone at the rate of 719 dry tons/ hr after grinding to the required size in a ball mill. The cyclone feed contains 40% solids by weight. The cyclone underflow is discharged at the rate of 469 dry tons/ hr andfound to contain 50% solids by weight.
Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 909 areas of 500–1600 cm2 g-1.The concentrate must therefore be re-ground in order to
measured the breakage rates at solids concentrations between 72 to 82% for an iron ore and found that the increase in solids concentration led to an increase in the slope of the breakage rate ...

Iron ore plays an important role in industrial raw materials worldwide. Nearly 97.5% of iron ore resources, including siderite, limonite, and oolitic hematite, etc. are typically low-grade iron ...
Outotec says it has been awarded a contract to supply key grinding equipment for ArcelorMittal's Las Truchas 2.3 Mt/y iron ore processing plant revamp …
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
• Peripheral ball mill: Discharge the ore through the periphery of the cylinder. ... But in actual production, the filling rate of the ball in the cylinder of the ball mill is mostly about 35%, which can keep the volume of the steel balls in the cylinder slightly lower than the horizontal centerline of the ball mill. ... 8 Types of Iron Ore ...
