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.

These grinders are used for grinding round and hollow jobs whether the internal surface of this job is completely round, ditched round, or is in taper. Small grinding wheels of 3 cm to 5 cm, are used in such grinders. Sometimes grinding wheels of special shape 0.2 cm to 0.3 cm. These grinders can be divided into two parts. a. Chucking Grinder

The TDG is a fluidised bed opposed jet mill with integrated high-performance classifier.

The AFG is suitable for the production of powders with a steep particle size distribution and sharp top size limitation in the ...

Mills are essentially cylindrical in shape and this design has been selected for very definite reasons. Mill capacity is a function of the mill volume and the load of grinding media. Therefore to obtain a mill of greatest capacity for any given space, pure logic dictates a mill having the greatest volume.
