Colloid Mill

CLM Colloid Mill

A colloid mill1A 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 in emulsions. in the industry is used for grinding solid particles and mixing emulsions2An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable)., pastes, suspensions3In chemistry, a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out.colloidal4In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. solutions, etc. The particles are crushed in a liquid medium. This method is called “wet” grinding and is considered the most effective for obtaining emulsion, homogeneous5Homogenization or homogenisation is any of several processes used to make a mixture of two mutually non-soluble liquids the same throughout. This is achieved by turning one of the liquids into a state consisting of extremely small particles distributed uniformly throughout the other liquid. and dispersion6A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. mixtures


The colloid mill has a steel case with a thermal jacket to keep the temperature inside the unit at the stable level. The material in a liquid form is fed into the mill and enters the gap between a rotating rotor and a stationary stator. Centrifugal forces in the rotor-stator gap disperse the solid particles. The gap is generally 0.05 mm and can be adjusted for finer dispersion. The rotating rotor speed is 125 m / s. The dispension achieves the material particles size 1 – 0.5 microns.


GlobeCore manufactures colloid mills specifically for production of bitumen7Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. and polymer-modified bitumen8One of the many methods employed to toughen bitumen is to blend it with polymers, either virgin or scrap, to produce polymer modified bitumen.. Colloid mills CLM achieve ultrafine dispersions and homogenization of bitumen solutions. CLM can be easily  installed into bitumen plants, and provides a high productivity  with control of grinding and pumping. The fineness of grinding is determined by the physico-mechanical properties of the material. The fineness of bitumen particles after a colloid mill is 1 μm9The micron is an SI derived unit of length equalling 1×10−6 metre (SI standard prefix “micro-” = 10−6); that is, one millionth of a metre (or one thousandth of a millimetre, 0.001 mm, or about 0.000039 inch).. The materials in solid and aqueous phases are fed into the mill where they are influenced by a number of forces. One of the forces is cavitation10Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation of small vapor-filled cavities, in places where the pressure is relatively low. -the collapse of cavities under the influence of internal pressure. It intensifies the dispersion and emulsification of bitumen. The mill’s thermal jacket regulates the heat  inside the colloid mill


First peanut paste or peanut butter were produced in 1890. A preparation of a paste from solid nuts was a complex and time-consuming task. In a history of this product, there have been many paste making methods invented that simplified  the process of grinding the raw materials into a homogeneous mass. GlobeCore developed a colloid mill particularly for making peanut butter. This device is suitable for preparation of any homogenized, dispersed systems. Each colloid mill is made to order, according to requests and requirements of the customer. On average, the manufacturing and delivery of the device takes 45 – 60 working days. CLM can be used both  separately and as a part of the production line.

The CLM Colloid Mill is designed specifically for the production of highly stable colloidal solutions, fine suspensions, mixtures and emulsions. It uses the principle of “wet” grinding due to the conical rotor and stator that have larger width entries and narrower exits. Additionally, the complex geometric surface of the rotor creates greater turbulence which breaks the particles apart.
colloid mill
Under centrifugal force and high relative speed between the rotating rotor and the fixed stator, liquids and semi-liquids become emulsified, finely dispersed and homogeneous mixtures.

The CLM colloid mill is specifically designed for production of highly stable colloid solutions, super-fine suspensions and emulsions. The mill applies the wet milling principle due to the rotor and stator cones’ larger gap width at the input and smaller gap width at the outlet. Additionally, the complex geometry of the rotor surface creates intensive turbulence to shear particles



PRODUCTIVITY UP TO 4 M ³ / HOUR The mill features high production rate; it allows to produce highly emulsions as well as colloid suspensions, and ensures high degree of homogenization with particle size down to 1 micron. The mill can be retrofitted into existing lines of production. To facilitate high quality grinding, the product must enter the mill at designated solid to liquid phase ratio and constant rate.


PRODUCTIVITY UP TO 18 M ³ / HOUR The mill features high performance capacity, allows to produce highly emulsions, as well as colloidal suspensions, ensures high degree of homogenization and particle size to 1 micron. Processes are intensified by 100 – 600% compared to agitator. Besides, the device creates cavitation, i.e. explosion of caverns by internal pressure. The mill can be retrofitted into existing production lines.


PRODUCTIVITY UP TO 22 M ³ / HOUR The centrifugal force and high velocity of the rotor relative to the fixed stator cause liquid and semi-liquid materials to become homogenic and finely dispersed. The mill simultaneously disperses and homogenizes materials. A heat jacket allows to apply or dissipate heat to or from the grinding zone.

Colloid mills and their modifications are applied in:

  • road-construction industry – for bitumen modification by polymers etc, for producing anionic11The term anionic bitumen emulsion is derived from the migration of particles of bitumen under an electric field. The droplets migrate toward the anode (positive electrode), and hence the emulsion is called anionic. and cationic bitumen emulsions12The term cationic is derived from the migration of particles of bitumen under an electric field also. The droplets migrate toward the cathode (negative electrode), and hence the emulsion is called cationic., liquid rubber13Liquid Rubber is a waterproof coating suitable for a wide range of projects around the house, yard, or building site. and so on.
  • machine-building industry – for production of lubricating and cooling emulsions, lubricants, process mediums for cooling in heat intensive processes.
  • power industry – for “heavy oil + water” emulsion production and burning in boiler houses and other power generation systems (reduces heavy oil consumption by 7-10% due to increased degree of combustion efficiency, boiler efficiency increase by 2-3%, decrease of carbon and nitrogen oxide emissions to the atmosphere up to 50%,  waste product disposal). Conversion of liquid oil waste products into fuel (oil refinery, seaport, industrial waste). Mixing of stable fuel emulsions from oil sludge.
