Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.
The Bauxite Processing Machine naturally plays an important role in the working state. If the grinding roller shaft is bent and deformed, the Bauxite Processing Machine will mean that it cannot operate normally and stop working. So what is the reason for the deformation of the grinding roller shaft? 1. The feed particles are too large.
Bauxite grinding plant can deal with bauxite particles whose size is more than 6 mm. After the treatment of bauxite grinding equipment, size of bauxite particles turns into less than 20 microns, and this is very suitable for bauxite extraction process. Nowadays, bauxite ball mill is well received by local bauxite investors in Indonesia.
