Fluid Energy Mill Overview. ... A Fluid Energy Model 0808 Jet-O-Mizer utilizes 1,200-2,200 SCFM of air compressed to 100 psig for mineral and pigment grinding. It is equipped with replaceable cast Ni Hard liners for superior abrasion resistance. The outlet is equipped with adjustable vanes for fine-tuning the particle size distribution.
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.
The design of the Apex Fluid Energy Mill enables other processes and functions to be carried out such as: -. 1. Intimate mixing or coating one material with another while simultaneously grinding and classifying. 2. Simultaneous drying and grinding of moist materials by using heated compressed air or superheated steam. 3.

Fluid Energy mills such as pancake, loop, and fluid bed mills, are used to break down granular material to fine powders. All jet mills are continuously operating devices so an overall milling system requires additional equipment beyond just the mill. In the picture at the right, is a jet milling system using a Fluid Energy Jet-O-Mizer.

Uses: Fluid energy mill is used to reduce the particle size of most drugs such as antibiotics and vitamins. When strict quality control is desirable for the purpose of better absorption ( bioavailability ), this mill is the preferred one. Ultrafine grinding can be achieved. Moderately hard materials can be processed for size reduction.
In this study, the stochastic method is used to simulate the grinding process in a fluid energy mill: the product particle size distribution is regarded as the result of repeating elementary breakage events, i.e. M p =M 0 [T m] m, where M 0 is the row vector of the size distribution of feed particles, M p is the row vector of the size distribution of product particles, m is the …
The qualification fluid energy mill (FEM) (from Sturtevant Inc., Hanover, MA) was used in this study. It is 5.08 cm in diameter and 1.27 cm in thickness.Fig. 2(a) and (b) show the entire system of the grinding equipment and the cross-sectional view of the qualification FEM, respectively.The unit has three air inlets: two grinding air inlets and one feed air inlet.
A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heat-sensitive ...
fluid-energy mill. [ ¦flü·əd ′en·ər·jē ‚mil] (engineering) A size-reduction unit in which grinding is achieved by collision between the particles being ground and the energy supplied by a compressed fluid entering the grinding chamber at high speed. Also known as jet mill.

Principle Fluid energy mill : Fluid energy mill works on the principle of attrition and impact. The material is suspended in the air stream of high velocity, which helps in the milling of feed as the suspended particles collide with each other. Since fluid energy mill reduces the size of the particle up to 5um, it is also known as a micronizer.
High Speed Fluid Energy Mills. This type of equipment is used primarily for preparation of relatively low viscosity mill bases for inks and paints. The first is an impeller type which achieves dispersion by the appHcation of shear. The second type is in the form of a rotor—stator, and the dispersion is achieved by impingement or impact. [Pg.512]
