Colloid Mill
The design of colloid Mills is based on years of experience in wet communication, homogenization, emulsification, dispersion, fluidization mixing, etc.
The principle of the Colloid Mill is based on the Stator /Rotor Principle. The stator is ring-shaped with two different staggered special design tooth stages and conical shape tuning inside the stator with a special shape helical tooth system. The initial Rotor Stage is shaped with impeller blades as a preliminary drum, seizing the material, pre-breaking in, and throwing it into the first station tooth stage. The product is fed to the operating area of a Rotor, having a speed of approximately 3000 R.P.M. by a specially designed feed device. The product is processed by high shear, pressure, and friction between the Stator and Rotor, besides the high shear, beating, collisions, bombarding, and friction, the product is exposed to intense vibration which exerts its force in it through pressing and realizing actions. At the last stage of processing, the product is exposed to a basic oscillating frequency of 6000 Hz. The first upper oscillation of this stage lies with 18000 Hz utmost within the supersonic region, which explains high efficiency. The processed product continuously leaves the mill through the drain pipe, if required, it can be recirculated.
Due to the slightly deviating tapering of the milling surfaces of the stator and rotor, the annular gap becomes narrower towards the discharge section. The special design facilitates adjustment of the grinding gap by an exterior screw even during operation.
