The rotary kiln shell serves as the main structure of the rotary kiln, typically constructed from steel plates that are pre- fabricated into sections and then either riveted or welded together. Several kiln ring types are mounted on the shell, resting on corresponding support rollers, allowing the material to gradually move from the inlet end toward the discharge end. To ensure proper movement, the rotary kiln shell typically has a slope of 3% to 5%. To protect the kiln shell, a layer of refractory bricks, 100-220 mm thick, is applied to the interior.
Read MoreThe kiln shell is a cylindrical steel structure that forms the main body of a rotary kiln, used in industries such as cement, lime, and chemical processing. It serves as the vessel in which raw materials are heated, dried, and processed through controlled thermal conditions. The kiln shell is a critical component, influencing the efficiency and durability of the kiln.
Diameter and Length: Determined by the process requirements, typically ranging from a few meters to over 100 meters in length.
Wall Thickness: Varies depending on the size of the kiln and operational conditions, ensuring structural integrity.
Reinforcement: Rings or bands are used to strengthen areas prone to stress and deformation.
Expansion Joints: Included to manage thermal expansion and prevent damage.
Alignment: Ensures proper fit and rotation to minimize wear and operational issues.
Our productions mainly used in fields of mining, metallurgy, cement, sugar plant, petrochemical industry, construction, and recycling facilities, aggregate.
Which is including non-standard machinery components, custom castings, forged parts, gears, shafts, ball mill spares, rotary kiln etc.
1.Finite element analysis is used to calculate the strength of key components and determine the optimal structure to ensure the reliability of the rotary kiln.
2.We can customize the rotary kiln to meet your specific requirements.
3.Can producing the Rotary kiln with volume more than 5000t/d.
Regular Inspections: Check for signs of wear, deformation, and cracks.
Thermal Scanning: Use infrared thermography to detect hot spots and ensure even heat distribution.
Alignment Checks: Periodically verify the alignment of the shell to prevent uneven wear.
Refractory Maintenance: Inspect and replace damaged linings to protect the shell.
Lubrication: Proper lubrication of support rollers and thrust mechanisms to reduce operational stress.
