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 they require
Vertical or horizontal mounting position makes 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
MIXING MECHANISM
The first mixing zone utilizes sharp stator teeth to mill the fluid
Next, fine serrations accelerate the fluid between the ultra-smooth, hardened surfaces of the spinning rotor and stator gap
Finally, centrifugal forces impinge fluid on stator wall for additional refinement

COLLOID MILL
Greerco Colloid Mills | Northern California & Western Nevada
A colloid mill is an in-line high shear mill that disperses solids and/or liquids into a carrier liquid by forcing them through an adjustable gap between a fast-spinning rotor and a fixed stator. It gives tight, repeatable particle-size distribution and stable emulsions to the submicron range. Cal West Mashy is the exclusive Greerco representative for Northern California and Western Nevada.
Why an adjustable gap matters
The rotor-stator gap is set on the fly with a hand wheel, and an indicator dial records the setting. You change shear rate during production and return to the same setting batch after batch.
Typical uses
Solids incorporation, homogeneous dispersions, deagglomeration, rapid blending and particle-size reduction, in batch, batch-continuous or in-line arrangements (vertical or horizontal mounting).
Frequently asked questions
What is a colloid mill?
A colloid mill is a high shear rotor-stator mill that disperses solids or liquids into a carrier liquid through an adjustable rotor-stator gap, producing uniform particle size and stable emulsions to the submicron range.
