The extraction of iron from iron ore has togo through many stages, from the initial mining, crushing and grinding, tosorting and smelting. Our common iron is refined step by step, and in theprocess, iron ore. The ball mill is an indispensable device and can be said tohave contributed. So do you understand how iron ore ball mills work?
Iron ore ball mill working principle
The main body of the iron ore ball mill isa cylindrical cylinder. The cylinder body will be placed with about 30~40%steel balls according to the volume of different types of iron ore ball mills.When the ball mill is started, the main bearing is driven by the cylinder.Start to rotate slowly. At this time, the iron ore with a particle size of20~30mm is fed into the ball mill from the feed port. As the rotation speed ofthe cylinder is faster, the iron ore and steel ball are brought to a certainheight. After the fall, in this process, the iron ore, steel ball and the innerwall of the cylinder are also constantly colliding and rubbing each other,grinding the iron ore, when the qualified particle size is reached (usuallybetween 0.074mm~0.4mm), the material It is discharged.
The iron ore after grinding operation willenter the classifier or hydrocyclone, and the fine material will be dischargedthrough the overflow end, waiting for the next sorting stage, and the coarseparticles will be returned to the ball mill for re-grinding. If the feed sizeis coarse and the product size is required to be fine, segmental grinding isrequired, which may be coordinated by the lattice type and overflow type ironore ball mill. In addition, there are many kinds of iron ore, includinghematite, magnetite, limonite, iron oxide, etc. For this reason, Zheng Minewill divide the ball mill equipment into different materials, you can alsolearn about our iron oxide ball mill.
