• Colloid Mill

    Our Greerco Colloid Mill is the most versatile high shear mixer available. With a simple turn of the wheel, you can achieve the process results you have been looking for.



    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

    Standard Mill Construction

    • 316 SS wetted parts impregnated with Stellite for high wear resistance
    • Jacketed stator housing with SS connections
    • Lip seal shaft sealing
    • Explosion-proof motors
    • Painted base and supports
    • Viton elastomers
    • Sanitary, tri-clamp connections


     Optional Features

    • Alternative rotor-stator design
    • Mechanical seals
    • 440 harded SS rotor-stator
    • Alternative motor enclosures
    • All stainless steel supports and base
    • Push cart with casters for mobility
    • Macerating knife


    • 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
