bauxite crushing plant - shanghai zenith company
Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.
Bauxite ore in larger size will be fed into the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After primary crushing, the material will transferred to impact crusher by belt conveyor for secondary crushing; the crushed bauxite stone will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the othes will be returned to impact crusher for further crushing, thus forming a closed circuit. Size of final products can be adjust and graded according to your specific requirement. For further grinding, the selection for the equipment should base on your specifical requirement and the characteristics of the bauxite.

Bauxite mine is actually kind of ore minerals collectively formed mainly by gibbsite, a boehmite or a diaspore which can be used in the industry. Bauxite mine can be used widely in many industries among which the most important is to be used for refining aluminum in aluminum Industry, refractory and abrasive materials, and raw materials for high alumina cement. The quality requirements to bauxite mining vary according to their different applications.
The general process of extracting aluminum in industry is as follows: First you need to extract alumina from bauxite. Then the alumina will be changed to aluminum by electrolysis. Now there are mainly three methods for alumina production which include sintering, Bayer and joint method.
However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose DSMAC crusher or DSMAC grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple. Generally we use the professional DSMAC mining equipments for bauxite crushing. As the leading stone crusher manufacturer and grinding mill manufacturer, DSMAC has also been closely following the bauxite mining at home and abroad. DSMAC has manufactured large amount of mining equipments to global countries, such as jaw crusher series, impact crusher series, cone crusher series and the grinding mill series, etc. DSMAC mining equipments have been exported to more than 130 countries which are widely applied in mining industry including the bauxite crushing. For decades, DSMAC has always continued to innovate in the development, production, sales, and service sectors. Rich experience and high-tech applications help our products maximize customers satisfaction.
As the important resource of nowadays industry production, ore minerals are required nearly in every business in the industry. Together with the professional crushing, grinding and screening technology of world class, DSMAC supply professional ore mineral processing equipments including Metal Ore MineralsNon Metallic Minerals crushing plants, grinding equipments, screening machines and feeding machines.
bauxite crushing & phosphate rock processing
Three Reversible Impactors are located at the Piney Point Plant, Palmetto, Florida. This plant is part of the Davison Chemical Division of Borden Chemical Co. These machines reduce diammonium phosphate or granular triple superphosphate (GTSP) from a feed of 75 x 3.35mm (3 x 6 mesh) to an 852-952 minus 3.35mm (6 mesh) product. Capacity is 41 TPH (45 STPH) with 75 KW (100 HP) V-belt drive.
Single Roll Crushers are installed at the White Springs, Florida Plant of Occidental Chemical Co. The materials crushed are triple superphosphate and diammonium phosphate. The feed is 600 x 450 x 150mm (24 x 18 x 6) and product is 37.5mm (1.5). Capacities are 27-36 TPH (30-40 STPH). The relatively slow speed of 7.3 rad/s (70 RPM) assures long wear of the staggered tooth configuration. The proper tooth configuration assures that product top size will be quite uniform.
A Twin Rotor Impactor is installed at the Nichols, Florida Plant of International Minerals and Chemical Co. This is a machine equipped with two parallel rotor assemblies with opposite rotation so that material must pass in a narrow gap between the respective hammer circles.
There is no basic formula to determine Breaker capacity because of the many variables which must be considered including type of material, feed size, gradation of feed, and desired product size. Breaker size is based principally on a determination of the volume to be screened and the volume to be reduced in size.
An unusual crusher application utilizes a One-Way Hammarmill Installed at Companhia Mineira de Aluminio, San Paulo, Brazil. The feed is 300mm (12) maximum with a large portion being minus 150mm (6) . The feed is mine-run bauxite to which is added a caustic sodium aluminate solution to give a moisture level of 20 to 30%.
bauxite processing plant, bauxite ore crushing and ore grinding equipment
As we know, bauxite ore is very hard, so it takes a longer time for crushing. In the bauxite processing, the Jaw Crusher is used in the coarse crushing, and Impact Crusher is used in the secondary, Cone Crusher is in fine crushing. Usually, according to the quarry conditions, mobile crushing plants are also used in the bauxite quarrying.
Bauxite particles should be further grinded by the use of grinding mill. And the types of grinding mill are varied, including Ball Mill, LM series Vertical Shaft Mill, T130X Superfine Roller Mill, and Raymond Mill, etc.
To get aluminium concentrate, it adopts the method of gravity separation, adopting a Spiral Classifier.
