Bauxite, also known as bauxite or bauxite, is white or gray white. It is brown yellow or light red due to its iron content, with hardness of 1-3, opaque, brittle, extremely difficult to melt and insoluble in water. Its main component is alumina, a hydrated alumina containing impurities, which is a kind of earth like mineral. It is mainly used for aluminum smelting, refractory products, grinding materials, precision casting of military, aerospace, communication, instrument, machinery, medical equipment, etc.

Main process of bauxite grinding

Crushing stage

The bulk material is crushed by the crusher to the feeding fineness (15mm-50mm) that can enter the pulverizer.

Milling stage

Small pieces of materials that meet the grinding conditions enter the grinding chamber of the mill uniformly and quantitatively through the conveying and feeding system, and are ground into powder in the grinding chamber.

Grading stage

The milled materials are graded by the powder concentrator along with the air flow of the system, and the unqualified powder is graded by the powder concentrator and then returned to the grinding chamber of the main machine for grinding again.

Gathering stage

Powder conforming to the fineness enters the powder collection system along with the gas flowing through the pipeline, and the gas powder is separated. The finished powder is sent to the finished product bin by the conveying device, and then packaged by the powder loading tank car or the automatic packer.
