2. fluid-energy impact milling & micronization techniques 2.1. Spiral jet mill micronization The spiral jet mill is suitable for the fine and ultra fine size reduction of materials up to a Moh's hardness of 3 that display brittle crystalline grinding characteristics. They are typically used in applications where a ultrafine portion is required.
Fluid energy milling of ibuprofen was investigated and found generally hard to mill in its dry state due to its ductility and low melting point . In the study, ibuprofen crystals of different sizes (<40 μm or 50–250 μm) and morphologies (plate-like and needle-like crystals) were first produced by controlled crystallization.
cutting – energy consumption and energy savings due to tribology, saving on cutting tool consumption and quality improvement that could accrue from advances in tribology. The ASME Research Committee on Lubrication has studied the role of tribology in energy conservation. It concluded that about 5.5 percent of U.S. energy consumption is

Hydrodynamic systems use fluid motion to transmit power. Power is transmitted by the kinetic energy of the fluid. Hydrodynamics deals with the mechanics of moving fluid and uses flow theory. The pump used in hydrodynamic systems is a non-positive displacement pump.
Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling: The basic principle of fluid energy mill is to induce particles to collide against each other at high velocity, causing them to fracture into fine particles.
fluid can be a gas or a liquid; both have applications in aerospace technology. In convection heat transfer, the heat is moved through bulk transfer of a non-uniform temperature fluid. The third process is radiation or transmission of energy through space without the necessary presence of matter. Radiation is the only method for heat transfer ...
The kinetic energy of high-velocity jets of a gaseous fluid is employed to violently agitate and swirl solid particles. A gaseous fluid is introduced into the mill as plural jets, having supersonic velocity, which are directed at an angle around a circular section of the grinding chamber. Particulated solid is entrained within the jets to form a fluid mass which is swirled within the circular ...

F. Delogu, G. Mulas, in High-Energy Ball Milling, 2010. 5.2 Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).
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 ...

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.
