The new e-Jet^® System (efficiency, economy, ecology)

Were air jet mills not economical for your product and application in the past? Not anymore! We have closely examined the energy efficiency of this technology. The result is a completely new grinding method.
Until now air jet milling, due to its energy consumption, was only cost efficient when applied to high value products. Now many other materials can be economically processed in our fluidized bed jet mills.
Economy is only one of the distinguishing features of our new e-Jet^® System (patent pending). 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 e-Jet^® System.
Convince yourself! This energy efficient milling system is now available for direct comparison in our laboratory in Hanau!

The new s-Jet^® System (steam, superfine)

The s-Jet^® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d₅₀ 0,2 µm) can now be achieved with fluidized bed jet mills.
As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet^® System uses superheated steam as its milling gas.

Since steam moves at a higher speed of sound than air, the circumferential speed of the current inside the classifier wheel can rise, which in turn influences the G forces effecting the material being classified. This is the decisive step toward classifying particles into the submicron range for the first time, via dry grinding.

Above all, are the interesting economical aspects of the new s-Jet^® System: Compared to air, steam provides a considerably higher jet energy. Jet speeds of up to 1,200 m/s can be achieved and the kinetic impact energy of the particles inside the fluid bed rises fourfold! This leads to a distinctive increase in throughput as opposed to air operations (more than double the capacity). Therefore, the throughput of a machine can be increased immensely, without changing the fineness!!
