When the rocks are about 3/8inch or smaller, they are fed as a slurry into the two ball mills. Each ball mill is turned by a single 3,000 horsepower electric motor. These mills contain literally hundreds of thousands of threeinch diameter steel balls that pulverize the ore until it is like fine sand or face powder.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4 or 5in. balls are more commonly used for ballmill grinding.
Elemental chromium and CrCu powder mixtures were milled in a vibrational ball mill under air, nitrogen and oxygencontaining argon atmospheres. Structural changes during milling and the thermal stabilities of the milled powders were examined by means of Xray analysis, transmission electron microscopy and differential scanning calorimetry.
How To Extract Chromium From Chromite Ore XSM is a leading global manufacturer of crushing and milling equipment (How To Extract Chromium From Chromite Ore),XSM also supply individual (How To Extract Chromium From Chromite Ore...) crushers and mills as well as spare parts of them.

Mass fraction of chromium in chromium cast iron alloy exceeds over 11%, the ratio of chromium to carbon is greater than damage effects of carbide to mat. High Manganese Steel Liner Xinhai Bcll Mill High Manganese Steel Liner is used for protecting ball mill cylinder against the impact of grinding medium and ore.
This study was aimed to investigate the galvanic interaction between pyrite and chalcopyrite with two types of grinding media (low alloy and high carbon chromium steel ball) in grinding of a porphyry copper sulphide ore. Results indicated that injection of different gases into mill altered the oxidationreduction environment during grinding.

It has been studied the correlation of the obtained microstructures in cermets of CuCrAgAl2O3 with the physical properties and the fabrication method varying the components proportions to obtain by powder metallurgy a material with good electrical conductivity and also good mechanical strength compared with pure copper allied to efficient fabrication and economical energetically process.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Abstract. Copperbased nanocomposite pseudoalloys with a chromium content of 25 to 45 wt % have been obtained via the spark plasma sintering. The treatment of powder blends with various chromium contents in the planetary mills is found to cause pronounced changes in the electrical and mechanical properties of materials.
