ABSTRACT We present a study of talc grinding in an Alpine 100 AFG opposed air jet mill with an inline laser granulometer. The conditions for steady state operation have been determined from continuous grinding experiments and show that overloading occurs above a critical value of feed rate classifier resulting in unstable product size distribution.

Process optimization of jet mills for metallurgical powder

Process Optimization Of Jet Mills For Metallurgical Powder

The jet mill operates on the principle of collisions between particles to grind ultrafine powder material without the introduction of heat or any other external force and is capable of particle size reduction from about 100 microns down to 250 nm. The optimization process depends on parameters such as feed rate, grinding air pressure, physical characteristics of the solids density, hardness ...
