Principle of Fluid Energy Mill: It operates on the principle of impact and attrition. The inlet and outlets are attached with the classifier which prevents the particles to pass until they become sufficiently fine, (a). It helps in the determination of particle size and shape. The speed of air/inert gas is directly related to efficiency.
