- Hand wheel adjusts the rotor-stator gap on the fly, with an indicator dial marking gap position for repeatable process results
- Vertical or horizontal mounting supports batch, batch-continuous, or inline use
- Three-stage mixing action: sharp stator teeth perform initial milling, fine serrations accelerate fluid through the rotor-stator gap, then centrifugal force impinges fluid on the stator wall for further refinement
- Standard construction: 316 stainless steel wetted parts impregnated with Stellite for wear resistance, jacketed stator housing with stainless connections, lip seal shaft sealing, explosion-proof motors, Viton elastomers, and sanitary tri-clamp connections
- Optional features include mechanical seals, 440 hardened stainless rotor-stator, alternate motor enclosures, sanitary all-stainless supports/base, a mobile push cart, and a macerating knife
Greerco Colloid Mill
The Greerco Colloid Mill is a high-speed, high-shear rotor-stator mixer capable of batch, batch-continuous, or inline processing. The manufacturer positions it as the most versatile mill in its class, since the rotor-stator gap can be adjusted on the fly with a hand wheel to change shear rate without stopping the process.
Features & Benefits
Applications
- Manufacturer cites emulsification, solids incorporation, homogeneous dispersions, solids deagglomeration, rapid blending, particle size reduction, and prepackaging product refinement
- Available in horizontal models (W200V, W250 and similar) with the manufacturer noting time-tested design proven over years of continuous operation with minimal maintenance
Performance
- Gap setting indicator dial on the W250 model reaches a maximum reading of 39
- Flow rate varies by gap setting on horizontal mills, per the manufacturer's published flow rate vs. gap setting data
