Rotary Kiln Bauxite Ore Specification/ Calcined Bauxite Buyer in China


Packaging Details: Packing in 1 MT big bag or 25KG pp bag.

Delivery Detail: Within 20 days upon receipt of T/T prepament or workable L/C.



The company produces other kilns with the diameter1-5 meters, widely applies in the metallurgy, the chemical industry, bears professions and so on material, Ceram site, papermaking. This kind of kiln’s supporting is divided into two forms of rolls and skids, the transmission may use direct-current or the exchange frequency conversion velocity modulation, and has many kinds of form seals to adapt the different operating mode.

Our company could also meet different needs from different customer to produce Non-standard kiln.
Rotary kiln is composed of cylinder, gears, supports device, kiln liner and kiln tail sealing equipment, kiln head hood, and combustion.

Cylinder as heated pivoting part, made of high-quality carbon steel plate, is supported on the first or some gear in order to control the turning of cylinder. Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, bigger rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and head sealing equipment is installed on feed and discharge end.

Q:What are the fireproofing materials of the external wall included?
According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
Q:The fire prevention board line is made of what material?
The line is a kind of composite stainless steel decorative profiles which outer layer is the matte frosted stainless steel plate and inner liningl is wooden material. It do not need to render with fine wood and also need not to buy a stainless steel plate cutting, cutting, bending, such as multi-channel intricate process, processing production. It is convenient to install through the buckle button directly on the booth. When installation, it only needs to be bolt and plug to be fixed on the wallafter blanking cut. compared with the traditional wooden play crural line, the profile is more beautiful and firm, and environmental friendly. And compared with the traditional craft production of stainless steel line, it's cheaper and more convenient to install. This product is not only sitable to decorate in the family, but also is more suitable for the hotel, hotel, office building, and the application of all kinds of public places.
Q:what is the material of fixed first rate fire resistant window?
Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
Materials Industry
Q:What is the quote of fireproof and soundproof materials used in KTV?
acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤: 0.02 elongation at break: ≤80kPa flexure strength: ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.
Q:Which refractory is better for building 1500 degree kiln ?
High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
Q:What kind of material is refractory bauxite?
Bauxite (aluminous soil; bauxite), also known as alumina or bauxite ore whose main component is alumina oxde, is a hydrated alumina containing impurities. It is an earthy mineral. It is white or gray, and as it contains iron, it is also brownish yellow or light red. Density of 2.4-2.5g / cm3, hardness 1-3, opaque and crispy. It is extremely difficult to melt.
Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
Q:Who knows the fire resistant level of the rock wool color plate?
The rock wool color steel rock wool board is used in a area of high ​​fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
