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 heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

The compressed air via dryer is sprayed into the grinding chamber through Laval jet nozzle, the material at the intersection of airflow is crashed, the powdered material enters into the classifying area on the top together with uprising airflow, under the action of centrifugal force from classifying wheel and draught fan, the oversized powder is repulverized and the qualified powder is ...
Oct 01, 1999· Determine the compressed air load on a system consisting of two air-cooled, oil-free compressors, each rated for 165 scfm at a discharge pressure of 125 psig. These compressors discharge to a 240-gal. receiver (V = 32 cu ft) with a dial pressure indicator and pressure transmitter that tie into the compressor.
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.
The processing division is supported by a 12,000 SCFM modern compressed air plant with independent power sourcing, a nitrogen gas production unit and liquid nitrogen storage. We are here to provide you with precision jet milling systems, custom processing and R&D services. For all your polymer processing needs–size reduction, blending, ...
The ConJet ® high-density bed jet mill is a spiral jet mill combined with a patented dynamic air classifier. This classifier enables the ConJet ® to achieve highest finenesses independent of the product load, and therefore also highest throughput rates. Applicable for finenesses from 2.5 to 70 µm (d97).
