The sieved good hematite mineral material is sent to the ball mill from the vibrating screen via the hoist and the feeder to be pulverized and ground again; the ground hematite fine material enters the classifier and precipitates in the liquid due to the specific gravity of the material. Different principles are used to wash and classify materials;

Types of Iron Ore - JXSC Machine

The following is an introduction to these four types of iron ore magnetite hematite limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust) but since iron is easily combined with other elements to form various iron minerals (compounds) there is little natural pure iron in the earth’s crust.

This is followed by a rougher magnetic concentrator and then a 7.9 m (26 ft) diameter × 13.6 m (44.6 ft) long ball mill. Each ball mill has two 7800 kW motors giving a total of 44 MW of installed mill power in each of the six grinding lines. The final product from these large regrind ball mills using small grinding media will be approximately 28 μm. The mills will produce a fine ore stream which enters finisher magnetic separators to produce the final concentrate.

Iron ore is the key material for steel production enterprises. Generally iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing grinding magnetic separation flotation and gravity separation etc. iron is gradually selected from the natural iron ore.

In the Laboratory

particles remain suspended. The original ferrofluids developed at NASA used finely divided magnetite prepared by grinding in a ball mill for several weeks to obtain particles of an appro-priate colloidal size. Carrier liquid surfactant and a dispersant were added during the grinding process to prevent agglom-eration of the nanoparticles.
