Comparing the operation efficiency of Symons cone crusher and hydraulic cone crusher, we find Symons cone crusher achieved better results in tertiary crushing. And if installing the same number of secondary and tertiary crushers, a part of operation is transmitted from tertiary to secondary crushers where the liner wear is three times less, which significantly influences on the cost reduction in the copper ore flotation.

Chromium processing

Most of the world's production of chromite (95%) is used in the metallurgical industry in the form of ferrochromium alloys. The alloys are produced by high temperature reduction (smelting) of chromite. They are essentially alloys of iron and chromium with much lesser amounts of carbon and silicon, the amounts depending upon the grade or type of alloy, and impurities such as sulphur, phosphorous and titanium. The conversion of chromite to ferrochromium alloys is dominated b...
