Colloid Mill

Our Greerco Colloid Mill is the most versatile high-shear mixer available.

Mixing Mechanism

1. The first mixing zone uses sharp stator teeth to mill the fluid.
2. Next, fine serrations accelerate the fluid between the ultra-smooth, hardened surfaces of the spinning rotor and stator gap.
3. Finally, centrifugal forces impinge fluid on the stator wall for additional refinement.

Versatility

The rotor-stator gap can be adjusted on-the-fly by turning a hand wheel.
Changing the gap setting allows the user to modify the shear rate applied to the fluid and achieve the desired process results.
Indicator dial defines gap-setting position and ensures process repeatability.
This machine is designed to handle a wide range of applications and empowers the user to make simple adjustments to achieve the precise product qualities required.
Vertical or horizontal mounting position makes the colloid mill ideal for batch, batch-continuous, or in-line applications.
Due to the nature of most high-shear applications, we offer an extensive rental pool for confirming the impact of Greerco™ high-shear technology on your process.
