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 is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …

Three crushing plants are used to reduce the size of bauxite for use in alumina factory. The ore is hauled to these crushing plants by truck from the mine. In the first step the ore is moved to a primary screen with two levels and are divided into three parts: (i) <20 mm (ii) between 20 mm and 10 cm and (iii) >10 cm.
