    Oct 19, 2016· Colloids presentation slides 1. COLLOIDS BY DEVI PRIYA SUGATHAN MSc 2. COLLOIDS A colloid is a substance microscopically dispersed throughout another substance. The word colloid comes from a Greek word 'kolla', which means glue thus colloidal particles are glue like substances. These particles pass through a filter paper but not through a semipermeable membrane.

  • Working and Principle of Colloidal Mill : Pharmaceutical

    Jun 20, 2020· The basic principle used in the colloidal mill is known as rotor-stator which is placed in a cylindrical vessel. The rotor and stator are placed close enough to create a narrow passage where the material to be reduced in size are passed through.

    Apr 03, 2016· Principle of Colloidal Mill Colloidal mill works on the principle of rotor-stator. The size reduction is affected due to shearing, when the material is passed between the narrow gap of milling surfaces of rotor and stator. A rotor turns at high speeds of 3000 20000rpm.

  • Colloid Mill: Operating Principles, components, Uses

    Jan 11, 2016· 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.

    Peptization or Deflocculation is the process responsible for the formation of converting precipitate into colloid by shaking with it an electrolyte.. This is particularly important in colloid chemistry or for precipitation reactions in an aqueous solution.When colloidal particles bear a same sign electric charge, they mutually repel each other and cannot aggregate together.
