ABRASIVE JET MACHINING
In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The jet of abrasive particles is carried by carrier gas or air. High velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet.

Chapter 8 Air Jet Milling - ScienceDirect
1. Introduction. Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Albus [1] gives a brief history of air jet mills. The first versions, developed in the late 19th century, used a jet of compressed air to project solids against a target.
Manufacturing Processes – II
Beam Machining (EBM) and high-energy coherent photons in case of Laser Beam Machining (LBM). Thus these two processes are often classified as electro-optical-thermal processes. There are different jet or beam processes, namely Abrasive Jet, Water Jet etc. These two are mechanical jet processes. There are also thermal jet or beams.
Air-Jet Spinning - an overview | ScienceDirect Topics
Air-jet spinning is also known as Vortex or fasciated yarn spinning. It was introduced in the 1980s. A basic air-jet spinning system is shown in Figure 9.12.Before the sliver from the drawframe is supplied to the air-jet spinner, combing is often used, as it is imperative to get rid of any dust or trash that could obstruct the spinning jets.
Air Texturizing Process - TEXTILE LIBRARY
The air texturing process was developed about 50 years ago. However, it took nearly 30 years before the first commercial machine for the production of air jet textured apparel yarns was displayed at ITMA in 1979. The air texturing process transforms flat multi-filament yarns into yarns with a spun like character.
Overview of milling techniques for improving the ...
Fluid energy milling, sometimes referred to as air jet milling, effectively reduces the size of drug particles from the range of 20–100 μm to less than 10 μm. In this micronization method, high velocity compressed air streams are injected into a chamber where the starting raw materials are fed by a rate-controlled feeder ( Fig. 1 ).

But it wasn't until Sir Frank Whittle of the Royal Air Force in the 1930s made the rst patent for the jet engine and showed the possibilities through reliable energy conversion. He made the rst static test in 1937. Two years later, in 1939, it was a German physicist named Hans von ...

Some reverse-air baghouses employ a supplemental shaker system to assist cleaning by increasing the amount of energy delivered to the bag. The source of reverse air is generally a separate system fan capable of supplying clean, dry air for one or two compartments at a gas-to-cloth ratio as high or higher than that of the forward gas flow.
