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.
reasons for bauxite beneficiation
Besides the caustic consumption reduction, the beneficiation plant decreases the refinery energy consumption and residue generation amount, as the overall bauxite quality is improved with the removal of the reactive silica.
To select suitable equipment and technologies, it is necessary to properly characterize the bauxite. The first step is usually to do a chemical analysis per size fraction. Then further laboratory testing of each of the unit operations considered to allow scale-up will be required in order to evaluate the possible parameters in an industrial plant.
