Component Specifications

Definition
The bowl body or shell is the primary structural component of a centrifugal separation bowl, typically a cylindrical or conical vessel that rotates at high speeds. It houses the separation chamber where materials are subjected to centrifugal force, enabling separation based on density differences. This component must maintain precise balance, withstand high rotational stresses, and provide controlled flow paths for separated phases.
Working Principle
The bowl rotates at high speed (typically 3,000-15,000 RPM), generating centrifugal force that separates materials based on density. Heavier components move outward while lighter components remain inward, with separation enhanced by internal discs or plates. The bowl's geometry and rotational dynamics create distinct zones for clarified liquid, solids, and interface layers.
Materials
Stainless steel (AISI 316L, 304), duplex stainless steel, titanium alloys, or specialized coatings for corrosion resistance. Material selection depends on process requirements: food/pharmaceutical (316L), chemical (duplex/titanium), marine (super duplex).
Technical Parameters
  • G-Force 5,000-15,000 × g
  • Capacity 50-5,000 L/h
  • Diameter 200-1000 mm
  • Rotation Speed 3,000-15,000 RPM
  • Surface Finish Ra ≤ 0.8 μm (food/pharma)

Frequently Asked Questions

What is the primary function of the bowl body in a separation bowl?

The bowl body provides the rotating chamber where centrifugal separation occurs, containing the material and creating the force field for separation while maintaining structural integrity under high rotational stresses.

How does bowl geometry affect separation efficiency?

Cylindrical bowls maximize solids holding capacity, conical bowls enhance solids ejection, and disc-stack designs increase separation surface area. Geometry optimization depends on specific separation requirements.

What maintenance is required for bowl bodies?

Regular inspection for wear, corrosion, and balance; cleaning to prevent buildup; and periodic replacement of seals and bearings. Proper maintenance ensures optimal performance and prevents catastrophic failure.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
