1. Product introduction of cement rotary kiln
Cement rotary kiln is the main equipment of cement clinker dry and wet production lines. Rotary kilns are widely used in metallurgy, chemical industry, building refractory, environmental protection and other industries.
2. Rotary Kiln body composition
The cement rotary kiln is composed of cylinder, drive assembly, support assembly of support and retaining wheel, kiln lining, kiln tail seal, kiln head and fuel assembly.
3. Application of cement rotary kiln
In addition to burning cement, cement rotary kiln is also used to burn clay, limestone, etc
In the production of refractory materials, raw materials are calcined in rotary kilns to stabilize their size, increase their strength, and then processed into shapes.
In addition, the cement rotary kiln has done a very good job in environmental protection. The cement rotary kiln is used to burn hazardous wastes and garbage, which not only makes the waste reduced and harmless, but also uses the waste as fuel to save coal powder and achieve waste recycling.
4. Refractory materials for cement rotary kiln
1. Refractory materials for air duct of cement kiln:
It is required that the refractory materials have the characteristics of wear resistance, erosion resistance, alkali chloride corrosion resistance, high temperature stability, etc. High strength alkali resistant brick, high strength alkali resistant castable, wear-resistant castable, calcium silicate board, diatomite brick and light castable can be used.
2. Refractory materials at the door cover of cement kiln:
Refractory materials are required to have wear resistance and high temperature volume stability. High alumina cement refractory castable, mullite castable, high alumina brick, phosphate bonded high alumina brick, calcium silicate board, etc. can be selected.
3. Refractory materials at the cooler of cement kiln:
The cooling area is generally divided into the first, second and third cooling sections. High alumina low cement castables and mullite castables can be used for the first section. High strength alkali resistant castables, high alumina low cement castables, mullite castables, etc. can be used in the second section. Alkali resistant castable can be used for the third section
4. Refractory materials for front kiln mouth:
The refractory materials for front kiln mouth masonry mainly include corundum castables, mullite castables and other amorphous refractories with good high-temperature performance.
5. Refractory materials for waste heat power generation system of cement kiln:
Refractory materials are required to have good high-temperature wear resistance, mainly including wear-resistant coating materials, wear-resistant ceramics, various wear-resistant castables and other materials.
6. Refractory materials used in waste gas treatment system of cement kiln:
Common refractory materials used in cement waste gas treatment system include high-strength alkali resistant brick, high-strength alkali resistant castable, mullite castable, corundum castable, steel fiber wear-resistant castable, silicon carbide wear-resistant brick, etc.
