Spiral jet mills have a static air classifier integrated into the mill housing, whereas fluidised bed opposed jet mills are equipped with a dynamic deflector-wheel classifier. The fineness is set as a function of the classifying wheel speed. All-important is a high product loading of the nozzle jets in order to achieve a high concentration of ...
Abrasive products will seriously erode most hammer mills, adding metallic contamination to the product. Materials that degrade with heat or have low melt temperatures are a problem in hammer mills because of the heat generated in the mill.In 1936 the first commercially practical jet …
The Spiral Jet mill has a simple structure with a classifying mechanism that utilizes the spiral airflow generated within the machine. It has the ability to ultra-fine grind raw materials with low-melting points to sizes of a few μm.

Jet milling or fluid-energy grinding via a spiral jet mill is a common method of comminution or pulverizing granular material into a fine powder with a narrow size distribution. The spiral jet mill, also called a pancake mill, is shown in the drawing to the left. This design was first described by NH Andrews in 1936 (US2032827)1.
Spiral Jet Mills. Most of the spiral jet mills currently on the market still have the original flat rectangular shape dating back to the 40's that creates turbulences (therefore caking problems) and do not allow laminar jet streams. Some mills still have the original lateral tangential product entry, with blowback problems, asymmetrical ...

Spiral jet mills, the most commonly used conventional micronizing machines, have a built-in mechanism of air classification. Particles are sorted by size using the forces of air on them within the grinding chamber. In a spiral jet mill, raw material is fed into the grinding chamber where high-speed, nozzle-fed gas accelerates the particles.
Dec's flexible, multi-format jet milling equipment is designed to satisfy the full range of these requirements. Available in open and contained arrangements our spiral jet mills provide the ability to micronize difficult and hard to handle products and serve many applications throughout the pharmaceutical, chemical, cosmetic and food industries.
Our spiral jet mills have been designed to guarantee precise scalability. This enables the active ingredient to be followed from its first R&D phases through to commercial launch; it allows us to operate with the same product from batches of 0.2 g up to several tons. We guarantee to reduce product build-up and achieve yields higher than 99% for ...

Laboratory mills are recommended for process and product development work. Laboratories are able to process just a few grams of a compound in the 1-in. jet mill, the smallest of its kind. The more common, 2-in. and 4-in. jet mills are the true workhorses of the laboratory applications. These mills are small, easy to disassemble and easily cleaned.
Spiral jet mill Jet mills are frequently used in the pharmaceutical industry and also for the production of fine-grade chemicals. Jet milling uses highly compressed air or other gasses to reduce particles into powders with dimensions as small as one micron across.
Jet Mills are often used in fine size reduction applications of hard or abrasive materials down to D97 > 2 µm or when high purity and minimal contamination is required. There are many specialized variation of 'The Jet Mill' that include fluidized bed jet mills, spiral …
Jet milling is vital to the toll processing industry. As a primary particle size reduction method, jet milling uses high-pressure, compressed air to create high-velocity collisions between the material's particles.. How small can jet mills grind? The grinding generally results in particle sizes in the 1- to 10-micron average particle size range. Some products require smaller particles, as ...

Jet Milling is a concept of feeding powder particles into a flat circular milling chamber and subjecting the same tangentially with pressurized air or nitrogen through a venturi. The Powder Particles are accelerated in a spiral movement inside the milling chamber by a number of angular holes in a ring and placed around the periphery of the chamber.

The objective of this work is to develop a milling model for a continuous self-classifying spiral air jet mill. Its foundation is a population balance model with selection and breakage distribution functions that have been related to a minimal number of mill-dependent and powder-dependent parameters.
Within a spiral jet mill the size reduction and the classification are accomplished simultaneously in the same volume. Size reduction occurs mainly near the outer walls as a result of particle–wall and particle–particle collisions. The size reduction intensity is …
