Bauxite is the primary ore of aluminum, typically reddish, brownish, or yellowish in color. It mainly consists of aluminum hydroxides (Al(OH)₃) along with iron oxides, silica, and titanium minerals. Bauxite is the essential raw material for aluminum production but is also used in refractory, chemical, and cement industries.

What is a Bauxite Crushing and Screening Plant?

A bauxite crushing and screening plant is an industrial facility where natural bauxite ores are crushed into smaller sizes and classified according to particle size. The purpose is to prepare bauxite for aluminum production or other industrial uses.

Main Equipment:

  • Feeding bunker (initial ore loading)

  • Jaw crusher (primary crushing)

  • Impact crusher or cone crusher (secondary crushing)

  • Vibrating screen (size classification)

  • Conveyor belts (material transport)

  • Dust suppression systems (environmental protection)

Working Principle:

  1. Bauxite is loaded into the feeding bunker.

  2. Large ore pieces are crushed by the jaw crusher.

  3. Smaller fractions are crushed further in an impact or cone crusher.

  4. Vibrating screens classify the material into desired fractions.

  5. Classified products are stored or directly shipped.

Application Areas:

  • Aluminum production (main raw material)

  • Refractory materials (furnaces, kilns)

  • Chemical industry (aluminum-based chemicals)

  • Cement production (additive or raw material)

  • Abrasive industry (grinding wheels, sandpapers)

  • Road construction and filling material (for lower grade bauxite)
