Spiral jet mill with integrated dynamic air classifier to achieve the desired end fineness; Size reduction via gas blasted from grinding jets in an annular arrangement; End finenesses from d97 m to 40 m (dependent on density) General. The ConJet#174; HighDensity Bed Jet Mill combines a spiral jet mill with an integrated classifier wheel.
Process optimization through the adaptation of grinding conditions provides energy savings of up to 30 % compared to the conventional operation of air jet mills. Products that in the past could only be economically processed in mechanical mills, can now be micronized even more economically in our CGS Fluidized Bed Jet Mill using the eJet
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media.

Opposed Jet Mill. Opposed jet mills are a type of microniser used for the superfine grinding of a wide range of materials where other forms of mill are unsuitable, particularly in cases where the feed material is hard, already relatively fine, has a low melting point or where high purity products, without contamination, are required.
A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. Particles leaving the mill can be separated from the gas stream by cyclonic separation.
A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding
It all began in 1976 with the Comil#174;, the original conical mill. A revolutionary concept at the time, that has since evolved into the global processing standard. For more than 40 years, we have been improving and refining the Quadro conical milling technology reaffirming our leadership with every generation.

Jet mills are impact mills which are used to achieve maximum fineness values at maximum product purity. Such particle sizes can only be obtained in connection with an air classifying step. Spiral jet mills have a static air classifier integrated into the mill housing, whereas fluidised bed opposed jet mills are equipped with a dynamic deflectorwheel classifier.
The Fluidised airflow jet Mill consists of an air supply unit, grinding unit, powder grading and powder collecting facility. The compressed air from the air supply unit mixes with the particles from the feeding unit in the grinding chamber and forms the air solid phase flow.
Comparison of various milling technologies for grinding pharmaceutical powders Mostafa Nakacha, JeanRene#180; Authelina, Alain Chamayoub,*, John Doddsb aAventis Pharma, 13 Quiai Jules Guesde, 94400 Vitry sur Seine, France bEcole des Mines dAlbiCarmaux, Campus Jarlard, 81013 Albi, France Abstract This paper examines fine grinding techniques in current use in the pharmaceutical industry
Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heatsensitive and waxy material because no attritional heat is generated. Jet mill
The grinding container is made up of a tube that is held in a frame that is supported by means of springs which is filled to approximately 80% total volume with porcelain or stainless steel balls. During milling, the entire body of the mill undergoes a small but frequent vibration that is generated by an eccentric motor, and size reduction occurs by repeated impact.
Final finenesses in the submicron range (example: d 50 #181;m) can now be achieved with fluidized bed jet mills, which was only possible by means of wet media milling process at the past. As opposed to conventional dry grinding processes with fluidized bed jet mills, the sJet #174; System uses superheated steam as its milling gas.
