There are several different models of raw bauxite,we own have three bauxite quarry,and can produce 5000 tons bauxite per month.

Classification of bauxite buyer

Classification of bauxite buyer

1.Refractory 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:

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:

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 manufacturing technique of refractory material: Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank

Q:What are the applications of refractory?: Refractory usually refers to the inorganic non-metallic material, whose refractoriness is above 1580℃. And it can be used for necessary parts. You can search more information on the Internet. It can be used in ferrous metal metallurgy, chemical, ceramics and so on. Fire material generally refers to above 1580 ℃ refractoriness of inorganic material, where the material can be used in corrosion, the network is very strong look, we know that colored when the metallurgical, chemical-resistant ceramics, etc. of industrial production high temperature. Different things are needed in different industries.

Q:Is there requirement for radiation indicator in refractory?: All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.

Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: The cut is relatively transparent if you jam, we have also used silicon manganese alloy

Q:Who knows the texture of fire-proof wooden door material?: The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. with fireproofing function..

Q:Does anyone know the difference between refractory and thermal insulation material?: The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.

Q:what is the grading standards of external wall thermal insulation materials?: external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q:Who knows what kind of material the fire-proof plate use, and is it good?: It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.

Q:What brands are the best in the A-level refractory materials?: This is two descriptions, glass wool refers to the texture of insulation materials, and A-lever refers to the combustion performance of fireproof materials. Generally the glass wool can achieve A-level combustion performance, unless you have add too many other combustible materials to it.
