Component Specifications

Definition
The Shell Body is the primary cylindrical or conical structural element of a rotating drum shell, designed to withstand mechanical stresses, contain materials or processes, and provide mounting surfaces for other components. It serves as the foundational framework that maintains geometric integrity during rotation while resisting deformation from internal pressures, thermal gradients, and dynamic loads.
Working Principle
The Shell Body operates by maintaining structural integrity through its geometric design and material properties, distributing rotational forces evenly, and providing a sealed or controlled environment for internal processes. It transfers torque from the drive system while containing the operational media.
Materials
Carbon steel (ASTM A36, A516 Gr.70), Stainless steel (304, 316L), Alloy steel (4140), Aluminum alloys (6061-T6), Composite materials (fiber-reinforced polymers) with thickness ranging from 6mm to 50mm depending on diameter and pressure requirements.
Technical Parameters
  • Length 1000-15000 mm
  • Diameter 500-5000 mm
  • Surface Finish Ra 3.2 μm or better
  • Wall Thickness 6-50 mm
  • Pressure Rating Up to 10 bar
  • Weight Capacity Up to 50,000 kg
  • Operating Temperature -40°C to 300°C
  • Straightness Tolerance 1 mm per meter
  • Concentricity Tolerance ±0.5 mm
Standards
ISO 11337, DIN 28018, ASME BPVC Section VIII, EN 13445

Frequently Asked Questions

What are the main failure modes for Shell Bodies in rotating drums?

Fatigue cracking at weld joints, corrosion-induced thinning, ovalization deformation from uneven loads, and thermal stress cracking from temperature cycling.

How is Shell Body thickness determined for specific applications?

Thickness is calculated based on internal pressure, material yield strength, safety factors (typically 4:1), corrosion allowance, and dynamic load considerations using formulas from ASME BPVC or equivalent standards.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
