A colloid mill is a machine used to disintegrate solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (Subjected to a massive shearing action that effects a time dispersion of uniform size) and an outlet.

Colloid mill works on the rotor-stator principle. The equipment breaks down materials by forming a dispersion of material in a liquid. Shearing takes place in a narrow gap between a static cone (the stator) and a rapidly rotating cone (the rotor). The rotor and stator construction using toughened steel or corundum to reduce wear.

The rotor of a colloid mill can differ from one machine to another. Still, the operating principle is the same for all. Each manufacturer incorporates specific features that result in changes in operating efficiency.

COLLOID MILL is suitable for Homogenizing, Emulsifying, Dispersing, Mixing, and Comminuting liquids to highly viscous products. Based on the rotor and stator principle. It.s are available in plain as well as water jacketed model which is suitable for heat sensitive product. In your case, as required, the machine will be of water-jacketed type.

Operation

The product is fed to a rotor’s active area, having a speed of 3000 rpm, by a specially designed feed device. The product is processed by high shear, pressure, and friction between the stator and rotor and subjected to intense vibration, which exerts its force on pressing and releasing action. Due to the slightly deviating tearing of the stator and rotor’s milling surface, the angular gap becomes narrower towards the discharge section. This processed product continuously leaves the mill through the drainpipe and recirculated if required.
