Anchor or Gate Type Impellers are used for high-viscosity mixing, particularly in applications with fluids that range from 5,000 to 50,000 centipoise (CP) in viscosity. These impellers have a special design that allows them to closely follow the vessel walls, providing effective scraping and agitation to ensure homogeneous mixing. By sweeping the walls and physically agitating the material, they prevent sedimentation and aid in heat transfer. They are typically used in processes like paste or gel mixing, adhesives, and coatings, where thick or viscous products are involved.

Mixing Tips for selection of Anchor/Gate Type Impeller

Gums & Thickeners:

• Powder should be added as fast as possible to avoid viscosity buildup. HSD OR Rotor Stator should be designed to rapidly hydrate or disperse the powder.
• This will achieve agglomerate free solution with better productivity.

Mixing of High & Low viscosity Fluids:

• Start with low viscosity fluids as it will require smaller machine. Addition of high viscosity fluid should be at flow suction of impeller.
