Crushing Plant Flowsheet & Design-Layout
Extended experience in most crushing plants show that a minus 19MM (¾") rod mill feed can be and is being produced in three stages of crushing. In the majority of cases, the last crushing stage is closed circuited using anywhere from 10MM (3/8″) square to 14MM (9/16″) slotted openings on the sizing deck.

Bauxite: The principal ore of aluminum.
Use of Bauxite as an Abrasive. Calcined alumina is a synthetic corundum, which is a very hard material (9 on the Mohs Hardness Scale).Calcined alumina is crushed, separated by size, and used as an abrasive. Aluminum oxide sandpaper, polishing powders, and polishing suspensions are made from calcined alumina.

11.24 Metallic Minerals Processing
The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.
