Product Description
Features of calcination rotary kiln for bauxite
1) It is an inclined rotary cylinder, the raw material enter the cylinder through the high end of the machine,then move in with the movement of of the rotary kiln. Therefore, the rotary kiln is a conveying equipment.
2) It is a combustion device.
3) It has the function of heat exchange.
4) It has the chemical reaction function.
5) It has the function of degrading and re-using the waste.
Advantages of calcination rotary kiln for bauxite
◊. Energy-saving and environmental-protection, using wastes as fuel
◊. Solid structure, stable operation
◊. High-usage of thermal energy
Application of calcination rotary kiln for bauxite
1. Rotary kiln is commonly used in the production process of catalytic agent, molecular sieve and zinc oxide, etc.
As a result, you can find rotary kiln for bauxite in variety of industries, like steel annealing and nonferrous smelting industries, metallurgy and chemistry fields, and building industries, and more.
2. Rotary kiln system, which is also called a rotary calcine kiln, is a commonly used building material machine. Classifying by material properties, a rotary kiln falls into cement kilns, metallurgy chemical kilns, and lime kilns.
Technical parameters of calcination rotary kiln for bauxite
- Q: what's the standard of fireproofing material?
- Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- Mechanism analysis of silicon actionWhen silica fume is added to the carbon composite refractory, the phase changes and chemical changes are as follows:<1> Si (s) +C (s) =SiC (s) Delta G ~ =-522+1.50T (kJ)<2> Si (s) +MgO (s) =Si (g) +Mg (g) Delta G ~ =203.9-0.13T (kJ)<3> 2Si (s) +CO (g) =SiC (s) +SiO (g) Delta G ~ =-963.2+0.31T (kJ)<4> SiC (s) +CO (g) =SiO (g) +2C (s) Delta G ~ =81.47-0.15T (kJ)<5> SiO (g) +CO (g) =SiO2 (s) +C (s) Delta G ~ =-668.8+0.33T (kJ)From the above diagram and the reactions seen at high temperatures has joined the Si SiO and Mg volatiles, but <4> and <5> reaction have played a role in inhibiting carbon oxidation, and the condensation of SiO2 to a certain extent the role of protective film.The total reaction process is CO reduction to C, and there is a certain volume expansion, so that the pores are blocked and the density of bricks is increased. Therefore, the oxidation resistance of brick is improved.
- Q: What the fireproofing materialare of the refractory kettle and where they can be sold?
- Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
- Q: What are the characteristics of thealuminium oxide refractory?
- Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours
- Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- Exports should be fumigated outside of South East asia. Pallet packing is the most common, convenient and inexpensive.
- Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
- You don't give a cent to this question, no one will answer it
- Q: What are the fire resistances of grc partition panels?
- It's ok, calcium silicate itself is a non-combustible material. Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls. We can talk about it in detail.
- Q: How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
- The simplest is to find a refractory construction unit, should provide you with oven curve.
