Collid Mill

A Colloid Mill is a high-shear mixing device used to reduce the particle size of solids in suspension, emulsify liquids, and homogenize semi-solid mixtures. It operates by using a rotor-stator mechanism that creates intense mechanical shearing forces, making it ideal for applications that require fine dispersion and emulsification.

Harsha Engineers India’s colloid mills are specially designed for precision processing in industries like pharmaceuticals, cosmetics, food processing, chemical manufacturing, and biotechnology. These machines are capable of handling both low- and high-viscosity materials, making them extremely versatile for producing creams, ointments, sauces, suspensions, and emulsions.

Constructed from high-grade stainless steel (SS304/SS316L), our colloid mills offer corrosion resistance, GMP compliance, and hygienic operation. The gap between the rotor and stator can be finely adjusted to achieve the required particle size distribution (typically 1–5 microns). The system ensures uniform particle breakdown, which enhances product stability, texture, and bioavailability in pharmaceutical formulations.

A Colloid Mill is a high-efficiency grinding and mixing machine designed for the homogenization, emulsification, dispersion, and fine grinding of liquid and semi-liquid materials. It reduces particle size and ensures a smooth, stable, and uniform mixture, making it highly suitable for industries that demand consistent product quality. At Harsha Engineers, we manufacture robust Colloid Mills in MS, SS 304, SS 316, and GMP-compliant designs, offering durability, hygiene, and versatility for a wide range of industrial processes.

Shearing, grinding, and high-speed mixing are the three main ways the Colloid Mill works:

Through a hopper, the product enters the mill.
The gap between the stationary stator and the high-speed rotor is small.
Intense shearing action, friction, and turbulence reduce the particle size and create a fine, uniform dispersion or emulsion.
The processed material is discharged as a smooth and stable product.

Available in Mild Steel, Stainless Steel 304/316, and GMP models.
Rotor-stator system with high speed for effective particle size reduction.
The gap between rotor and stator can be adjusted to the desired level of fineness.
