Colloid Mill Works With Shearing, Grinding High-Speed Stirring Grinding Process Occurs In The Relative Movement Between The Two Teeth With One Revolving In High Speed And Another Still, Which Makes The Material Between The Teeth Receive Strong Shearing And Abrasion In Addition To High Frequency Vibration And High Speed Swirl.
The mill consists of two steel plates nearly touching each other and rotating in opposite directions with high speed. The solid particles are ground down to colloidal size and are dispersed in the liquid to give the sol. • 'Colloidal graphite' (a lubricant) and printing 25.
The colloidal solution is the solution that has the particle size ranging from true solutions and suspensions. The range of the diameter of the dispersed particle is from 10 Angstrom to 2000 Angstrom. Some of the methods of purification of a colloidal solution are stated below:
Milk fat. Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum, Figure 2.15. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3 – 4 µm and there are some 10 10 globules per ml.
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 rotorstator principle a rotor turns at high speeds lead to smaller droplets, down to approximately 1 m which are more resistant to emulsion separation.

This mill has been successfully employed for the production of nanoparticles of albendazole, danazol and omeprazole as well as probucol for the enhancement of their dissolution and absorption properties. A major drawback of media milling is the erosion of the balls arising from the intensive mixing forces in the vessel.

Colloidal Stability ESS5855 Lecture Fall 2010 Definition • Structure – In general, a colloid is a system consisting of one substance (the dispersed phase: a solid, liquid, or gas) finely divided and distributed evenly (relatively speaking) throughout a second substance (the dispersion medium or continuous phase: a solid, liquid, or gas)
COLLOIDAL SILICA. Composition: Despite the fact that colloidal silica has the same chemical formula as quartz sand, SiO 2, the two materials could hardly be more different in their effect on paper machine operations. The key difference is size. The subunits of colloidal silica particles are typically in the range of 1 to 5 nm.
