Lab Colloid Mill

These labs colloid mill finds its application in the processes where the superfine level of grinding with a homogenized mixture is required. High shearing force is applied to the optimum result for the even particle size reduction.


The Laboratory scale colloid mill is a machine that is used to reduce the particle size of a solid in suspension in a liquid, or to reduce the droplet size of a liquid suspended in another liquid. This is done by applying high levels of hydraulic shear to the process liquid. It is frequently used to increase the stability of suspensions and emulsions. The colloid mill is used for various applications such as Superfine grinding, homogenizing, emulsifying, dispersing, mixing and extracting of liquids, ointments and highly viscous products in pharmaceutical, cosmetics, suspensions & emulsion industry.

The product is fed to the hopper which leads the product into the gap between rotor and stator. The product is subjected to a high degree of shearing, cutting and rubbing between two metal toothed surfaces of rotor and stator and towards the discharge section. The processed product continuously leaves the mill through drain pipe if required, it can be re-circulated by three way cock and re-circulating pipe assembly.


  • Laboratory scale colloid mill is used for Homogenizing, Emulsifying, Dispersing, Mixing, Comminuting of Ointment, Liquid and highly viscous products research and development institutions, pharmaceutical laboratory, and pharmacy colleges.
  • Design is cGMP – Current Good Manufacturing Practices compliance.
  • All contact parts AISI 316 & non contact parts AISI 304.
  • Easy to adjustment gap between rotor and stator.
  • Three way cock assembly with re-circulating pipe.
  • Easy to Moveable and dismantle all contact parts for cleaning.
  • Silicon food grade seal.
  • Separate discharge spout for highly viscous products.
  • Optional: Horizontal or vertical drive model, water cooling systems, Explosion proof electrical.
