Calcined Bauxite For Refractory
Products Description
Introduction
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .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 84%to88%.the heating is carried out in rotary kilns.
Calcined bauxite, also known as rotary kiln bauxite, is a type of aluminum ore that is primarily used for its high alumina content and low impurities. Calcined bauxite is produced through a process of heating bauxite in a rotary kiln at high temperatures until it undergoes a metamorphic process that results in a dense, hard material with a variety of uses.
The properties of calcined bauxite include high hardness, high density, and high refractoriness. It is also resistant to abrasion, water, and chemicals, making it a popular material for a variety of applications. Calcined bauxite is typically available in a range of sizes and grades that can be tailored to specific applications.
One of the primary uses of calcined bauxite is as an aggregate in high-friction, anti-skid applications, such as road surfacing. Calcined bauxite can provide excellent traction on both wet and dry surfaces, making it a safe and effective solution for high-trafficked areas. It is also used in the manufacture of high-temperature ceramics, as well as castables and refractories that require high alumina content.
In addition to its technical applications, calcined bauxite is also used in the decorative arts, including as an aggregate in terrazzo flooring and as a filler in resin-based countertops and other decorative surfaces. It can also be used as a filter media in water treatment plants, due to its pore structure and ability to remove impurities from water.
Overall, calcined bauxite is a versatile and valuable material that offers a range of applications in a variety of industries. Its high alumina content, combined with its physical and chemical properties, make it a popular choice for a variety of technical and decorative applications.
Applications
Raw bauxite is typically classified according to its intended commercial application,such as abrasive ,cement ,chemical, metallurgical, and refractory .as raw material for use in high alumina and super duty refractory bricks and shapes ,plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.

FQA
1. What is the difference between brown corundum and white corundum?
A: Brown corundum is darker in color and higher in hardness, which is suitable for grinding materials with higher hardness; white corundum is lighter in color and more transparent, which has better insulating properties and is suitable for use in the fields of electronic components and optical devices.
2. What are the types of refractory raw materials?
A: Refractory raw materials include high alumina bricks, aluminum silicate bricks, silica bricks, silicon carbide and many other types, which should be selected according to the specific use scenario.
3. What is the method of using sandblasting raw materials?
A: Put the sandblasting raw material into the sandblasting machine and spray it onto the surface to be treated by compressed air to achieve the effect of removing stains, engraving patterns and so on.
