JET MILL :
Pulverization takes place in the central chamber of the jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself. The interior of the chamber is designed to allow recirculation of over-sized particles, enhancing the incidence and the effect of these collisions. As particles are reduced in size and progressively lose mass, they naturally migrate toward the central discharge port, making precise classification both automatic and precisely controllable.
COLLOIDAL MILL :
COLLOIDAL MILL is used to reduce the particle size of a solid present in different liquid forms or solid forms of the pharmaceutical ingredients in pharmaceutical industry.
Colloidal Mill reduces the size of particles of solids that are suspended in a liquid, when a liquid suspended in another liquid, meaning that they are immiscible, this machine is used alternatively to reduce the size of droplet.
It is mainly reduce the solids which are present in the suspension or emulsion or the reduction in the suspension droplet size. It is almost used for the all types of materials for the reduction. The end result of this type of mix is very stable mix which is able to resist contamination by water or bleed. In fact this is the method used in mixing cement base grout. The colloidalmill uses a method known as shearing.
