– HORIZONTAL BATCH MIXING

INDUSTRIAL

TWIN SHAFT

mixer

Scott Equipment’s Industrial Twin Shaft Mixer uses two counter-rotating shafts to create fast, uniform mixing with excellent batch-to-batch repeatability. Paddle/ribbon and paddle/paddle agitator configurations move material efficiently, incorporate liquids quickly, and blend consistently across a wide range of powders, granules, pellets, feed ingredients, fertilizer, and other bulk materials.

Available in capacities from 1 to 1,500 ft³ with sanitary and custom configurations available.

WHAT IS A TWIN SHAFT MIXER?

An industrial twin-shaft mixer is a horizontal mixing machine that uses two counter-rotating agitator shafts to move and blend materials throughout the mixing chamber rapidly. The opposing shafts create a fluidized mixing zone while moving material from end to end and side to side for fast, uniform blending.

Twin shaft mixers are commonly used for powders, granules, pellets, feed ingredients, fertilizer, food ingredients, minerals, and other bulk materials that require short mixing cycles, consistent blend quality, or uniform liquid addition.

Paddle/Ribbon Design

Scott Equipment’s paddle/ribbon agitator is effective because it combines two distinct mixing actions into a single agitator. Rather than relying solely on paddles or ribbons, the design provides simultaneous conveying, lifting, folding, and blending, resulting in faster, more uniform mixing with less energy and shorter batch times.

HOW DOES SCOTT’S TWIN SHAFT MIXER WORK?

HOW TWIN SHAFTS MOVE MATERIAL

Inside the mixer, two horizontal shafts rotate in opposite directions. Each shaft has Scott Equipment’s paddle/ribbon combination.

The paddle/ribbon combination moves material from end-to-end and side-to-side.
Creates a continuous, efficient movement of material across the mixer.
Optional paddle/paddle design

RAPID, UNIFORM LIQUID INCORPORATION

Liquids are introduced through a top-mounted header pipe with multiple inlet ports for fast, uniform distribution.

Optional liquid manifold box
Available in a variety of header pipe and inlet port sizes
Nozzles tailored to your material for consistent liquid addition
