Product Description:

73% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Raw Material for Refractory

Product Description:

Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,

is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.

Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.


Size of particles: 0-1mm,1-3mm,3-5mm,5-8mm,8-15mm,0-5mm,0-50mm

Size of powder: -200mesh,-270mesh,-325mesh


Bauxite clinker is mainly used for manufacturing high-quality refractory products, refractory castable, sagger, kiln furniture, crucibles, precision casting industrial,refractory ceramic,ceramic fiber products, etc


Calcined Bauxite Grade:

1.Refractory Grade:

Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.  

3. Rotary calcined bauxite:

 Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.

4. Shaft kiln calcined bauxite:

Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom.

Q:The structure of refractory material
Q:What are the additives and recipes of refractory?
Add FDN.
Q:How much is the content of boron carbide in refractory material?
Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
Q:Can someone professionally introduce the classifications of refractories?
Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:What are the fire resistance ratings of the glass partition?
Hello, friend. The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer.
Q:Which are fire proofing thermal insulation materials?
Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?
Q:What is shapeless refractory?
Q:How many kinds of fireproof materials are there in the market?
rock wool board• inorganic thermal insulation mortar• glass wool board• expanded glass• ceramic foam plate• sand aerated concrete• haydite concrete• foam cement• vitrified micro bubble panel
Q:What is the principal part of silicious refractory material
Silicon nitride and aluminite powder as well as dextrin
