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.

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%.

Ball mill, also called grinding mill, ball grinding mill, is the key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, with medium hardness. They are manufactured with highest quality material and workmanship; deliver the most efficient, trouble free and economical combination of material ranging from (5-30mm) down to varying product sizes.

Cone crushers are main equipment for medium/fine crushing of ores and rocks with different hardness in mining, forging, construction, chemical industry and power stations. They have features of advanced structure, high output rate, easy adjustment and their products have uniform grain distribution.
