      • To confirm the safe delivery of the equipment to the user site.
  •  To ensure that no un-authorized and or unrecorded design modifications shall take place. If at any point in time, any change is desired in the mutually agreed design, Change control procedure shall be followed and documented.
  • To ensure the proper installation and commissioning of the equipment.
  • MACHINE DESCRIPTION
  • The design of colloid Mills is based on years of experience in wet communition, homogenization, emulsification, dispersion, fluidization mixing etc.
  • The principle of Colloid Mill is based on the Stator /Rotor Principle. Stator is ring shaped with two different staggered special design tooth stages and conical shape tuning inside stator with special shape helical tooth system. Initial Rotor Stage is shaped impeller blades as preliminary drum, seizing the material, pre-breaking in and throwing it into the first station tooth stage. Product is fed to the operating area of a Rotor, having a speed of approximately 3000 R.P.M. by 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 exert their force in it by means of pressing and realizing actions. At last stage of processing product is exposed to be 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 though the drain pope, if required, it can be recirculated.
  • Due to the slightly deviating tapering of the milling surfaces of stator and rotor, the annular gap becomes narrower towards the discharge section. The special design facilitates adjustment of the griding gap be an exterior screw even during operation.
