Calcined Bauxite Material

Calcined bauxite is an important raw material for two major applcations: refractories and abrasives. Smaller volumes are consumed in other applications including proppants, welding fluxes, and antiskid surfaces. In calcined bauxite processing operations, many types of machines will be involved, such as clacined bauxite crushing equipment. SBM provides customized crushing solution for you.

Calcined Bauxite and India

A possible new supplier to the international calcined bauxite markets may be India. India currently imports 40-60% (about 100,000 tpa) of its calcined bauxite requirements form China. Spurred by expansion of domestic steel production, a scarcity of acceptable quality of bauxite from China, and rising import costs, drives are now underway in India to produce high grade bauxite from domestic bauxite sources.

At present, India is a very minor producer of non-metallurgical bauxite, despite having occurrences of high grade bauxite in west coast and central India. This is attributed to limited efforts to test high grade bauxite occurrences in regions outside the main bauxite producing area around Gujurat, and limited R&D and technology for calcining bauxite.

Calcined Bauxite in China

China dominates supply Despite the wider supply choices, consumers of abrasive grade bauxite often compete with consumers of refractory grade bauxite for the same supply sources in China. Historically, abrasive grade has come from the provinces of Henan, Guizhou, Shanxi, Guangxi, and Sichuan. In recent bauxite has been used to produce BFA domestically owing to favourable electricity costs. As a result, demand for abrasive grade in other regions has decreased because of cheaper Chinese exports.

Calcined Bauxite Crushing Equipment

The choice of calcined bauxite crushing equipment depends on the properties and amount of material to be crushed. Gyratory and jaw crushers are the bulk of primary crushers applied in mining operations nowadays. Roller impact crushers, VSI crusher are often used in secondary crushing operations. Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.

The major equipment in a primary crushing circuit usually includes only a crusher, vibrating feeder and belt conveyor. Secondary and tertiary crushing circuits have the same basic equipment items, along with screens and surge storage bins. There are also mobile crushing plant which could be easily move on the working site.
