The crushing chamber of the flat jet mill is in the shape of a horizontal disc, and it is also called a horizontal disc jet mill. It is composed of grinding chamber, separation device, feeding device, air duct, etc. (Fig. 1).The working principle is like this: the compressed gas (air, superheated steam, or inert gas) generates a high-speed jet Today, most pigments used are of synthetic origin. Examples of organic pigments are phthalocyanine or quinacridone and examples of inorganic pigments are chrome oxide or iron oxide. The Fine Impact Mill Condux 680 with pin disc counter rotating design.

Effect of the milling method and particle structure on the color
The pigment peak intensities milled with the planetary mill were less than that of the Jet-mill (See 3.2). In SEM analysis, the particle shape after calcination was spherical, angular after ball mill, flaky after planetary, and rounded after jet mill. Jet mill was the closest milling method to the particle shape after calcination.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 mill or spiral jet mill was introduced. This was the predecessor to our current Micron-Master® design. Up to that time, dry grinding in the sub-sieve range of 625 toFrequently Asked Questions : Jet Pulverizer

Jet Mills
In a jet mill, the grinding gas (usually compressed air) is fed into the grinding chamber through special nozzles and accelerated so strongly that the particles are entrained. In the process, the particles repeatedly collide with each other and are thus comminuted.
