The screening process is just as important as the crushing itself. Screens are the heart of every rock processing plant. They are used to classify materials both in different stages of the crushing process and in final product separa-tion. Designed as a non-welded frame with adjustable vibration features for different material types and screening

Impact crushers: Impact crushers are used to crush bauxite ore into smaller particles by striking the material with a rotor at high speed. They are popular for their ability to produce a high-quality end product, even when working with harder materials. VSI crushers: VSI crushers are used for tertiary and quaternary crushing of bauxite.

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 …
