Fluid energy mills may be classified in terms of the mill action. In a fluidized bed jet mill, schematically illustrated in Figure 2.19, the grinding energy is created by gas streams from horizontal grinding air nozzles.Particles in the fluidized bed created by the gas streams are accelerated towards the center mill chamber colliding with slower moving particles

Jul 05, 2020 Jul 05, 2020 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
