Calcined Bauxite

(1.1)
Supplier From China
Dec-16-21

The main ingredient of bauxite also known as alumina is aluminum oxide.
It is an earthy mineral colored white or gray white and could also appear to be brown yellow or light red due to iron inside it .
Calcined Bauxite is produced by high temperature calcination.
Product usage
Aluminum Industry. Used for national defense, aviation, automotive, electric appliance, chemical industry, daily necessities, etc
Precision Casting.Calcined bauxite powder can be used for produce mold precision casting and used for military industry, aviation, communication, instrument, machinery and medical equipment department.
Used for Refractory Product .The refractoriness of calcined bauxite could be as high as 1780 .And it also has excellent chemical stability and good physical properties.
Silicate Aluminum Refractory Fiber. With advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance .It can be used for steel, non ferrous metallurgy, electronics, petroleum, chemical industry ,astronavigation , atomic energy, national defense and other industries. The calcined bauxite is added into the  high temperature electric arc furnace which is about 2000 2200 and then process by high temperature melting, high pressure and high speed air or steam injection, cooling and then it become into Silicate Aluminum Refractory  Fiber which is white as cotton.It can be pressed into fiber blanket, fiber board or woven into cloth to instead of high temperature industrial furnace lining brick of smelting, chemical , glass industry and other industry . Firefighters can use refractory fiber cloth to make clothes.
Manufacture alumina cement, abrasive materials, ceramic industry and other aluminum compounds in chemical industry which for alumina produce.

Calcined Bauxite:

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application.

We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices.

Applications of Calcined Bauxite:

Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%.

Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.

Features Of Calcined Bauxite

Calcination is a process of heating, hence calcined bauxite is obtained by heating the high grade ore of the bauxite. Heating further removes the moisture content from the ore and thus results in the increase of the alumina content.

Supplier From Kanpur, Uttar Pradesh, India
Supplier Of Bauxite & Aluminium Ore
 
Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.

Supplier From Beijing, China
Supplier Of Bauxite & Aluminium Ore
 
Calcined Bauxite is obtained by calcining (heating in a Kiln) superior grade Bauxite at high temperatures (8500C to 16000C), this process removes the crystalline moisture leading to a higher alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 84 % to 88 %.

Calcined Bauxite is used as raw material for manufacturing fused alumina and high alumina refractories. Ashapura produces Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc.; we are committed to provide consistency in quality and availability of product at extremely competitive prices.
