Component Specifications

Definition
A blade plate is a flat or curved metallic component mounted on the shaft of a chemical reactor agitator. It converts rotational energy into fluid motion through hydrodynamic forces, creating turbulence, shear, and circulation patterns essential for chemical reactions, heat transfer, and mass transfer processes in industrial reactors.
Working Principle
The blade plate operates on hydrodynamic principles where rotational motion creates pressure differentials. As it rotates, it pushes fluid radially and axially, generating flow patterns (radial, axial, or tangential) that promote mixing, suspension of solids, dispersion of gases, and enhancement of heat and mass transfer coefficients.
Materials
Stainless steel (316L, 304), Hastelloy, Titanium, Nickel alloys, or specialized coatings for corrosion resistance. Material selection depends on chemical compatibility, temperature (up to 300°C), pressure, and abrasion requirements.
Technical Parameters
  • Diameter 200-2000 mm
  • Thickness 3-20 mm
  • Blade Count 2-6 blades
  • Rotation Speed 50-500 RPM
  • Surface Finish Ra 0.8-3.2 μm
  • Power Requirement 5-100 kW
Standards
ISO 2858, DIN 28136, ASME BPE

Frequently Asked Questions

What factors determine blade plate material selection?

Material selection depends on chemical compatibility with process fluids, temperature range, pressure conditions, corrosion resistance requirements, abrasion from suspended solids, and regulatory compliance for industries like pharmaceuticals or food processing.

How does blade design affect mixing efficiency?

Blade geometry (pitch angle, curvature, width) determines flow patterns. Radial blades create high shear for dispersion, axial blades promote top-to-bottom circulation, while specialized designs like pitched-blade turbines optimize both mixing and pumping capacity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
