SIZE REDUCTION AND SIZE SEPARATION
Equipment free from wearing ( fluid energy mill) may be used in this case. Laws governing energy and power requirements of mills . During size reduction energy is supplied to the equipment (mill). Very small amount of energy (less than 2%) actually produce size reduction. Rest of the energy is dissipated (wasted) in: (i) Elastic deformation of particles (ii) Transport of material within

Jet mill works on fluid energy. Consider a pancake spiral jet mill as an example. Micronizing and classification take place in a shallow, cylindrical chamber. High pressure air or steam is injected in this chamber through the specially designed nozzles placed at regular distance, on the peripheral wall. The axis of each jet is tangential to the circumference of a smaller, imaginary, concentric

The mixed fluid is then expelled from the jet through the secondary nozzle. This forms a cone that entrains the surrounding liquid, and a plume that spreads horizontally before rising to the surface. The plume imparts most of its energy to the fluid in its path, causing circulation and mixing throughout the

The particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
