Wet batch grinding of alumina hydrate in a stirred bead mill

Sep 24, 2001  Experimental investigations on the wet batch comminution of an alumina hydrate in a stirred bead mill are presented. The influence of some operating parameters (mass solids concentration, initial size of particles, stirrer speed and beads size) on both the specific energy and the size distribution of the ground product is discussed.

On the analysis of fine wet grinding in a batch ball mill ...

The influence of the slurry density on the fine wet grinding performances of a batch ball mill was examined for an alumina hydrate feed. Irrespective of the operating conditions, the size reduction process proceeds fast in the first period of grinding (20 min); then its rate progressively reduces and after 1–2 h the size of the product approches a final asymptotic value.

Alumina hydrates - Hindalco

Alumina hydrate (fine) After drying, alumina hydrate is ground using mechanical mills and ceramic lined ball mills to obtain finer particle sizes. Hindalco manufactures ground hydrate with different particle size (5-15 micron) distribution. Surface-treated fine hydrate as well as super-ground fine hydrate (1-2.5 micron) are also available.

Hydrated: Alumina hydrate, or alumina hydroxide, is used as a glaze because of its ability to stay in suspension in glaze slurries and adhesive qualities. Tabular: Tabular alumina is produced by heating aluminum oxide to 1650o C or 3000o F. It has a high heat capacity, excellent thermal temperature, strength, and volume stability.

Alumina hydrate particles have a high surface area and low dispersity and may have a low soluble soda content. They may be made by milling a liquid suspension of alumina hydrate, subjecting the milled suspension to classification into coarse and fine fractions, recycling the coarse fraction to the mill and recycling the fine fraction to the classification stage.

12.1 Primary Aluminum Production

Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.

How Aluminum is Produced Metallurgy for Dummies

The final product is a fine, dry, white powder, which is alumina. Alumina is then cooled and stored. Calcination is a heating process to remove the chemically combined water from the alumina hydrate. That’s why, once the hydrated alumina is calcined, it is referred to as anhydrous alumina. “Anhydrous” means “without water.”
