Component Specifications

Definition
The barrel shell is a precision-engineered cylindrical component that serves as the primary structural and protective enclosure for drum barrels used in various industrial applications. It is designed to withstand rotational forces, contain materials or products during processing, and provide mounting surfaces for internal components. Typically manufactured through rolling and welding processes, it maintains strict dimensional tolerances to ensure proper fit with end caps, bearings, and drive mechanisms.
Working Principle
The barrel shell operates by rotating around its central axis, creating a contained environment for mixing, drying, coating, or processing materials. Its cylindrical geometry ensures uniform distribution of centrifugal forces and provides consistent surface contact with internal materials. The shell transfers rotational energy from drive systems while maintaining structural stability under load.
Materials
Carbon steel (ASTM A36/A572), Stainless steel (304/316L), Aluminum alloys (6061-T6), Abrasion-resistant steel (AR400/500). Thickness typically ranges from 6mm to 25mm depending on diameter and application requirements.
Technical Parameters
  • Length 1000-8000 mm
  • Diameter 500-3000 mm
  • Surface Finish Ra 3.2-12.5 μm
  • Wall Thickness 6-25 mm
  • Weight Capacity Up to 50,000 kg
  • Straightness Tolerance 1 mm per meter
  • Concentricity Tolerance ±0.5 mm
Standards
ISO 286-2, DIN 1543, ASME B46.1
