Hybrid modeling of an industrial grinding-classification

Jul 01, 2015 An industrial grinding-classification process of diasporic bauxite is modeled based on the integration of phenomenological and statistical learning methods. The breakage characteristics of the ore and running status of the whole process are first investigated by laboratory testing and process sampling, respectively.

How to Choose Bauxite Grinding Mill?

Dec 12, 2019 Bauxite is a soil-like mineral that mainly composed of alumina, which is white or off-white, and appears brownish yellow or light red due to its iron content. It can be ground into fine bauxite powder that has many applications. Bauxite is generally formed by chemical weathering or exogenous action.

Bauxite

Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010,approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide
