Stator Screen: Diameter 50 - 500 mm, Hole Diameter 0.5 - 5 mm

Component Specifications

Definition

The stator screen is a critical component of a high-shear mixing head, typically a cylindrical or conical perforated screen that surrounds the rotor. It works in conjunction with the rotor to create high shear forces, breaking down particles and droplets to achieve fine emulsions, suspensions, and dispersions. The screen's hole size, pattern, and material determine the final particle size distribution and processing efficiency.

Working Principle

The rotor rotates at high speed inside the stator screen, drawing material into the gap between them. The material is subjected to intense shear, impact, and cavitation forces as it passes through the screen openings, resulting in particle size reduction and homogenization.

Materials

Stainless steel (304, 316L) or Hastelloy, with surface finish Ra ≤ 0.8 μm for food/pharma applications.

Frequently Asked Questions

What is the function of a stator screen?

It provides a stationary surface with precise openings that, combined with the rotor, generates high shear forces to reduce particle size and create uniform mixtures.

How do I choose the right hole size?

Select based on desired final particle size: smaller holes yield finer particles but reduce throughput. Typical range is 0.5-5 mm.

Can stator screens be repaired?

Minor damage can be welded and re-machined, but severe wear or clogging often requires replacement.
