fluid energy mill is meant for wet grinding true or false justify
Answers
Fluidized Energy mill, also known as micronizer or jet mill is a type of mill that consists of a hollow toroid that has a diameter of 20-200 mm depending on the height of the loop which can be up to 2 m. It operates by particle impaction and attrition.
A fluid or milling gas, usually air or inert gas is injected as a high-pressure jet through nozzles at the bottom of the loop. The powder particles in the mill are accelerated to high velocity.
The kinetic energy of the air plus the turbulence created causes interparticle (particle-particle collision) and particle-wall contact resulting in particle size between 2 and 10 micrometers. The fluidized effect transports the particles to a classification zone where the size classifier retains the particles until sufficiently fine to be removed.
true because
A size-reduction unit depending for its action on collisions between the particles being ground, the energy being supplied by a compressed fluid, (e.g., air or steam) that enters the grinding chamber at high speed. Such mills will give a product of 5 mu m or less; they have been used for the fine grinding of frits, kaolin, zircon, titania, and calcined alumina, but the energy consumed per ton of milled product is high.
