Colloid mill works on the rotor-stator principle. The equipment breaks down materials by forming dispersion of materials in a liquid. Shearing takes place in a narrow gap between a static cone (the stator) and a rapidly rotating cone (the rotor). To reduce wear, the rotor and stator are constructed using toughened steel or corundum.
A 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. Colloid mills work on the rotor-stator principle: a rotor turns at high speeds (2000 18000 RPM ). The resulting high levels of hydraulic shear applied to the process liquid disrupt structures in the fluid. Colloid mills are frequently used to increase the stability of suspensions and emulsions, but can also be used to reduce the particle size of solid
Rotor Safety Stop The milling chamber has an optional positive stop mechanism that will never allow the conical rotor to contact the stator. Colloid Mill Chamber Versatility The Bematek mill chamber can be easily rotated 360° to accommodate different piping arrangements in
Mechanism of Action Colloid mills fall under the category of rotor-stator mixers. In this model, a quickly rotating rotor draws the sample up; it is then pushed in a centrifuge-like fashion through a stator that contains many small slots.
Mixing Mechanism The first mixing zone utilizes sharp stator teeth to mill the fluid Next, fine serrations accelerate the fluid between the ultra-smooth, hardened surfaces of the spinning rotor and stator gap Finally, centrifugal forces impinge fluid on stator wall for additional refinement
Colloid mill plays important role in the reduction of the particles or solid materials present in the emulsion or the suspensions. The colloidal mill uses shearing mechanism. We offer the colloid mill with unique qualities and our machine also available at reasonable rate. In general, this device contains inlet and an outlet.

A colloid mill is a type of rotor-stator mixer often used in the manufacturing of emulsions and dispersions. It can also be used to reduce the particle size of solids in suspension. Inside the colloid mill, a high-speed rotor pushes the fluid through small holes in a stationary stator, creating extremely high levels of mechanical shear.

grinding mechanisms of mills and crushers are shown in Fig. 4.3, and they are classified according to the stresses involved in Table 4.1. Types (a) (Fig. 4.3(h)), colloid mill and sand grinder, which apply a frictional force between two rolling discs, are also used for grinding ferrite.
Jul 01, 2015· Cutter mills, roller mills, pestle and mortars and runner mills may be employed for this purpose. In these milling operations, the dried crude drug may be cut by sharp blades (cutter mill), impacted by hammers or crushed/compressed by the application of pressure (roller mill, pestle and mortar). Mechanisms by which milling improves drug
Mayonnaise requires a very specific shear, which is adjusted on conventional colloid mills by changing the gap. This is done by dialing an external ring mechanism that is not always accurate or repeatable. Tightening the gap also causes increased and fluctuating back pressure which leads to added stress on seals and texture changes in the

Ball Mill an overview ScienceDirect Topics. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Oct 18, 2014· Colloid mills are the preferred technology for highly viscous emulsions (> 5000 cp) commonly encountered in industry. A typical colloid mill consists of a conical rotor that rotates inside a static stator. As the emulsion is passed through the narrow gap between the rotor and stator, drop breakage occurs due to intense shearing.
Mayonnaise-type emulsions are best prepared with a hydrophilic surfactant. The emulsion is prepared by adding the surfactant to the water and mixing this solution with an equal volume of oil to form a crude emulsion. The emulsion is then passed through a colloid mill or homogeniser. More passes are made to incorporate additional quantities of oil.
A colloid mill utilizes a motor-driven shaft configuration that connects to the rotor (180) of the colloid mill to the electric motor rotor (138). patents-wipo. Mixers with shaking, oscillating, or vibrating mechanisms (B01F 13/00 takes precedence)
Colloid mills: Colloid mills are now quite widespread in the industry. They can be easily implemented on small processes requiring a milling of a slurry. Colloid mills are basically achieving a size reduction by submitting the product to intense shear forces created by a high speed rotor.
