Size of final products can be combined and graded according to your specific requirement. 2.The smaller crushed iron ore is fed to ball mill for grinding. Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank.
The grinding is currently done in four wet mills. Ground ore is then concentrated in the spiral plant using gravity spirals to increase the iron content from 38% to approximately 65%. The spirals utilize the forces of gravity, centrifugal action and friction to separate the heavier iron ore grains from the lighter waste rock particles.
Dec 01, 2006· Composite iron ore feed material of − 10.0 mm size fractions was used for this study which was collected from Joda iron ore beneficiation plant of M/s. Tata Steel Limited. Jigging tests were carried out in three phases to study the effect of three process parameters.
In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

Ball mill. The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but
