New Prefabricated Kiln

 

For quick and easy installation on flat concrete floor, very compact with latest prefab kiln technology incorporated.

 

The prefabricated kiln is a small or medium size kiln which is fabricated in our factory and delivered in separate modules to be joined at the site.

 

To reduce the investment and operation cost, we built the prefabricated kiln with suspended kiln wall, which is supported by steel structure. Thus the wheel of the kiln car will be exposed in the atmosphere, the working tempeature of wheel is designed around 80°C and the requirement for lubrication will be much less.

 

The Unique Waste Heat Utilization system provides less power requirement and less fuel consumption.

 

The main parameters of one new concept kiln with daily output of 100T to be executed in 2010 are given as below for reference only: 

  • The designed sintering temperature: 1,670°C;

  • The designed limiting temperature: 1,800°C;

  • Output: 100T/day;

  • Total length: 40m (net width: 4.6m);

  • Product:  Calcined Bauxite, Synthetic Mullite, Homogenized Materials (Synthetic Mullite, Synthetic Corundum, and so on);

  • Fuel:  Coal gas

  • Fuel consumption:  30,000~33,000Nm3 of coal gas per day (its heat calorie value is about 2,700Kcal/Nm3), which is equivalent to 900Kcal per kg of calcined bauxite (Al2O3: 80~93%) at sintering working temperature between 1,650~1,670°C

  • Power consumption: 35~45 KWH

  • Firing period: 120 hours

Q:Which fire-resistant materials have good viscidity?
The viscidity of fire-resistant materials is also known as the binding performance of fire-resistant materials. It can be divided into chamotte and chemical binder. Both can work at normal or high temperature. The most commonly used chamotte are soft clay and aluminate cement. The commonly used chemical binders include sodium silicate, phosphoric acid, aluminum sulphate, aluminium phosphate, phenolic resin, etc. Fire resistant material is a complicated and overloaded system and we cannot know its materials and chemical components from the name alone. Both gunning mix and repair mix contain binder components. If they can used after adding water, then they may contain clay or fire resistan aluminum silicate cement.
Q:what are the requirements of fireproofing material?
answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc. 2, fireproof panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
Common faults and causes of magnetic separator. 1. Motor of magnetic separator is overheated and its sound is not normal. Reasons for this failure are: 1) lubrication of bearing is bad or badly worn; 2)fan blade falls off or wears; 3)bad contact of switching circuit or disconnected to run a single phase; 4) voltage is too low. 2. Reasons for this failure due to overheated speed reducer are: 1) lack of oil or poor kerogen; 2) wear between gear and worm, or poor mesh; 3)poor lubrication of bearing or serious wear. 3. The sound of magnetic separator during operation is abnormal, lattice ball mill. Cylinder is stuck by obstacle, and even the cylinder can not rotate. The bottom box vibrates. Reason for this failure is often that it is stuck by objects in drag flask, otherwise magnetic patch falls off so that the cylinder screaks and pierce tube when it is serious. At this time, car should be stopped for maintenance and troubleshooting. Only when we master common faults and reasons of magnetic separator can we timely identify problems and solve problems. Better maintenance and repair of magnetic separator equipment are an important prerequisite to properly use equipment and ensure the construction.
Q:Can someone professionally introduce the classifications of refractories?
It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.
Q:What does refractory mean?
Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
Yes. After moulding by casting in the firing of 1450 ° degrees.
Q:Where do China and foreign countries do more refractory materials?

Q:How long is the fire endurance of Grade A fire resisting shutter
Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
Ceramic pottery ceramic collectively known species of high water absorption and low-grade sinter clay brick, tile-like material; high stone kinds of porcelain clay plus clay and other raw sintered body strength, low water absorption bowls, plates and other kinds of refractory high temperature structural materials are all non-machine ceramic refractory metal material belonging to a broader definition of ceramic refractory ceramic can be attributed to the high temperature ceramic refractory.
