مصنع لتجهيز البوكسيت/thailand bauxite ore crushing process
· The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which helps to speed up the followup speed of the chemical reaction.
