rod mill function in iron ore

Jun 03, 2020 Traditional taconite pellet-making processes use a rod mill to get the rock to the consistency of coarse sand, and a ball mill to grind the rock into a fine powder. This technology is still in use on Minnesota’s Iron Range by some facilities. A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 pounds.

Grinding Circuit an overview ScienceDirect Topics

A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]). This type of flow sheet is usually followed when the crude ore contains below 30% iron. The number of steps involved in crushing and grinding depends on various factors such as the hardness of the ore and the level of impurities ...

Investigation on Iron Ore Grinding based on Particle Size

May 28, 2020 The iron ore blend takes RT of 13 min when grounded in the BBM for 250% circulating load with 80% passing particle size of 56 m. The blend iron ore sample obtained from the BBM is composed of a higher percentage of fines and is not suitable for pellet making. So, the grinding is carried out in the LBM by varying the retention time of the mill.

Tubular Rod Mills ScienceDirect

Jan 01, 2016 This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is to reduce the size of ore, suitable for downstream use. Such a circuit ...

Rapid determination of Bond rod mill work index by

Jan 01, 2013 To calculate Bond rod-mill work indices, the four samples were screened and the particle size distributions plotted in Fig. 2.The plot was used to find F 80 of the samples for calculations. Fig. 3, Fig. 4 show the grinding kinetics of Pb, Cu, Fe, and Mn ores in the Bond rod-mill in different test-sieves. The slopes of all lines in the figures are equal to the k value of Eq.

Why Use Coke for Blast Furnace Ironmaking not Use Coal

Oct 06, 2019 Reduction: The coke carbon content is above 85%. The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content.
