The crushing ratio of vibrate cone crusher is up to 4-30 and the over crushing is little. If adopting the vibrate cone crusher, it will reduce the quantity of crushing segment.It is used for pulverizing ultra hard materials, such as FeSi,ferrotitanium, ferromanganese, corundum, spinelle, quartzite, feldspar, carborundum, concrete and so on.
The Bureau of Mines conducted laboratory-scale beneficiation tests on a sample of corundum gneiss from Montana to devise a method for beneficiating corundum for use as a substitute for refractory-grade bauxite. A flotation process utilizing petroleum sulfonate as the collector in an acid circuit was devised. Results showed that two flotation schemes each produced a concentrate exceeding the nati
Ordinary centrifuge-Zhejiang Dajin centrifuge Co., Ltd. ; Characteristic: LW series horizontal spiral discharge sedimentation centrifuge is a kind of mechanical equipment which uses the principle of centrifugal sedimentation to continuously separate the materials with density difference in suspension.
Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

Flotation is considered to be a physico-chemical process. Equipment in the form of mechanically or pneumatically agitated tanks or cells generate air bubbles, which provides the physical aspect. The chemical aspect is provided by reagents, which vary the surface properties of minerals and of the slurry medium for separation of valuable minerals ...
The adhesion of Escherichia coli onto quartz, hematite and corundum was experimentally investigated. A strain of E. coli was used that had the genes for expressing protein for silica precipitation.
Flotation behavior of hematite-quartz and calcite-corundum systems was studied before and after interaction with bacterial cell-free extract and bacterial cells.
Flotation is used to reduce the content of impurities in low-grade iron ores. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used in the iron industry.
The adhesion of Escherichia coli onto quartz, hematite and corundum was experimentally investigated. A strain of E. coli was used that had the genes for expressing protein for silica precipitation. The maximum cell adhesion was observed at pH <4.3
Spiral chute concentrator is high efficient gravity equipment for mineral processing. It doesn't need the power but utilize the different particles by the effect of gravity, water pressure and friction to achieve the separation of the useful minerals and gangue. It is made of the fiberglass with wear-resistant polyurethane and corundum cover.

The second period of corundum formation was the Pan-African orogeny (750–450 Ma). This includes primary ruby and sapphire deposits in the gemstone belt of East Africa, Madagascar, India, and Sri Lanka that are linked to collisional processes between eastern and western Gondwana (figure 2) during Pan-African tectonic-metamorphic events (Kröner, 1984).
Model LW centrifuge is the mechanical equipment used for continuously separation the materials in the suspension with density difference, by the principle of centrifugal settling. The basic principle is the drum and the spiral feeder rotate in the same direction but with a certain speed difference; The material is led into the feeding spiral ...
