Jet Mills (Fluid Energy Mills) are used to micronize pharmaceuticals, chemical, pigments, minerals, agrochemicals, thermoplastics and other heat sensitive and abrasive materials.
Jet Mills operate in compressed air, gas, nitrogen or high pressure superheated steam. These mills have no moving parts and thereby eliminating contamination due to contact with external grinding media. Also on attritional heat is generated during grinding process hence suitable for heat sensitive, waxy substances and low melting point materials are easily micronized.
Jet Mill works on fluid energy. Micronizing and classification are to be done in Jet Mill by taking advantage of fluid energy. Mill is designed to inject high pressure air or steam in to shallow cylindrical chamber through specially designed nozzles. Nozzles are placed at equally spaced on wall peripheral to have each jet is tangential at imaginary smaller circumference. Venture system will control the feed rate of the material precisely to get productivity. Jets generate high velocity vortex during material feeding which create vacuum to suck product in to high speed vortex. Suspended particle of the material is collided with each other and reduce themselves by attrition as well as collision whenever it comes in strong velocity gradients near the jet. The micronization takes place due to the collision between the incoming particles and the particles, which are accelerated into the spiral path. The larger particles of the product get retained at the periphery of the chamber by centrifugal force and micronized particles exit with the exhaust air from the central port of the chamber and get collected in to the cyclone collector system. Heavier or oversize particles are stay in chamber until micronized due to centrifugal force. The material can, be miller to an average particle size 0.2 to 5 micron or coarse ground to 400 mesh depending upon characteristics of the product. In general, input feed size of 200 mesh with air pressure of 7 kg/cm2, adequate quantity of air and controlled feed give better results.
