bauxite for sale/bauxite buyer/sell bauxite ore

Discription:

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.

Q: For refractory, what is critical particle size? Thank you.: Critical granularity means the maximum size of particles in refractory.

Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??: which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.

Q: What are the construction measures of refractory material in winter? Please descriptive briefly.: The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.

Q: Where is the sizing nozzle for refractories? Just enter the line, master into!: This is the use of steel tapping water procedures inside!!

Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?: You can add some animal hair, like bristles. After all, we don’t have so much hair. Remember not to use cement, because it will crack. Instead, make use of animal hair, lime, yellow mud and sand, after mixing up, and they would be firmer while in calcination.

Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.: there mainly are five fireproofing glasses, the first one is laminated composite fireproof glass, the second one is wired fire-resistant glass, the third one is special fireproofing glass, the fourth one is hollow fireproof glass,the fifth one is high strength monolayer cesium potassium fireproof glass.

Q: who knows how to classify the fire resistant levels of fireproofing material?: Grade of fireproofing material: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.

Q: What are grade classifications of the external walls for fireproofing?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the comprehensive unit price is very expensive.
