Tri-Mix Turbo-Shear High-Shear Mixing System Data Sheet - Copy 08/10/2026

How does it work?

The Tri-Mix™ Turbo-Shear™ utilizes mechanical and hydraulic shearing to dissolve powders, blend miscible and non-miscible solutions, prepare lotions and creams, and disperse pigments. A center shaft, which can be run alone or with a double-motion agitator, operates at speeds up to 3,450 RPM. The scraped-surface, double-motion agitator is used to efficiently pull product from the vessel walls during each blending revolution. The scraped-surface agitator portion operates at speeds up to 50 RPM.

Here’s how the Tri-Mix™ Turbo-Shear™ can help achieve your operational goals:

•  Product viscosities up to 2,000,000 CPS on primary double-motion means you get the product right, every time.
• Available from as small as 10-quart research models to as large as 1,500-gallon production vessels.
• High ratio of hydraulic to mechanical shear means less heat, which improves product consistency and increases overall safety (when processing temperature-sensitive products).
• Sanitary design means you pass government regulations with ease and save valuable cleanup time.
• High-velocity axial and radial product flow means production will never get clogged up or slowed down.
• Continuous high or low flow mixing head means you get the power you need when you need it most.
• Unique double-motion agitator offset frame means uniform scraping action and continuous product flow.
• Custom designs mean you get custom results, especially in difficult applications.
• Batch-to-batch uniformity means your customers can count on your product.
• Product scale-up means we easily grow with your operation.
• Our Process Guarantee, based on free testing in our 25-gallon lab Tri-Mix™ Turbo-Shear™, means you have peace of mind.

Particle Size Reduction

In a particle size reduction test, we used a 25-gallon style "D12T" Lee pressure kettle with Tri-Mix™ Turbo-Shear™ agitator. The preparation by approximate weights consisted of: epoxy resin (23%), emulsified in water (29.54%) with Cellosize thickener (.20%), and surfactant (.30%). Here are the results:

We started with double-motion scrapedsurface agitator at 30 RPM.

• After five minutes, particle size was 55 microns.
• After 60 minutes, particles were reduced to 30 microns.

Then we used the 3,450 RPM Turbo-Shear™ with a standard head configuration.

• After an additional 40 minutes, particle size was 5 to 7 microns.

Next we added Cellosize thickener (1.04%), flint (20.48%), and pyrophyllite (25.43%). The double-motion and Turbo-Shear™ agitators were run simultaneously for one hour.

• Final particle size was 2 microns.
• Final product viscosity was 40,000 CPS.

Lee Tri-Mix™ Turbo-Shear™ High-Viscosity Mixing System

1. Robust Double-Motion Scraped-Surface Agitation pushes high-viscosity ingredients down the sides of the vessel into the high-shear mixing head.

2. Inside Counter-Rotating Mixing Bars provide additional mixing power to move ingredients forcefully around the vessel.

3. High-Shear Mixing Head expels the product at high velocity through slots in the head, creating hydraulic and/or mechanical shear to force the product to the top or bottom of the vessel, depending on head configuration.
