History of Colloidal Mills Essay - 967 Words

COLLOIDAL MILL Colloid mill is a machine that is used to reduce the particle size of a solid. It is mainly reduces the solids which are present n the suspensions or emulsions or the reduction the droplet size in the suspensions. It is almost used for the all types of materials for the reduction. Collidal mills HISTORY The Rolls Royce of Mixers the high shear colloidal mixer as used by Team Mixing Technologies, is the leading colloidal mixer in the industry by most grouting experts world-wide. High-shear colloidal mixers are internationally recognized as the most efficient method of mixing cement-based grouts and other materials. Colloidal mixing results in very stable mixes which resist bleed and water contamination. The invention†¦show more content†¦Rotors and the stator may be smooth surfaced or rough surface. With the rotor and the stator there is a thin uniform film of material between them and it is subjected to the maximum amount of shear. Rough surfaced mill add intense eddy current, turbulence and the impaction of the particles to the shearing action. Principle 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. The 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, emulsions and can also be used to reduce the particle size of solids in suspensions. Higher shear rates leads to smaller droplets of 1 micron. Based on a rotor rotating at high speed and very close to a conical stator, the particle size is done by modifying the gap between the rotor and the stator. Working The material is placed into the mill though the inlet hopper. It is then passed through the narrow gap between the rotor and stator and thus reduced the fine particle size. A colloid mill is a hydraulic shear producing device. The colloid mill works to reduce the size of the suspended droplets, creating a mixture within the liquids that is much more uniform and complete. The mill allows the solid particles toShow MoreRelatedEvolution Of Nanoscale Science And Technology5337 Words   |  22 Pagesa bad effect on the economy or natural systems . that leads to use rules about the using nanotechnology .
