Process Technology for recovered Carbon Black (rCB)

Worldwide over 1,800,000,000 (1.8 billion) tires are reaching the end of their lifespan every year. A huge number, which leads to a high demand for recycling.

One way is to incinerate the tires to produce energy, which is not a sustainable future solution as the resources are lost. A second way is Pyrolysis, which generates oil, gas, steel and recovered Carbon Black (rCB) as final products. Especially the rCB can be used to replace the virgin Carbon Black in various applications. Most important is the fineness of the rCB, which determines the final use. To reach the fineness required, NETZSCH offers machines which meet the specific requirements of recovered Carbon Black to achieve the highest performance with the finest cuts.

CGS Fluidized Bed Jet Mill

The combination of an air jet mill and a dynamic air classifier represent fine dry grinding in perfection. The highest of final finenesses with an exact maximum particle size limitation become reproducible. The development of the new e-Jet® and s-Jet® grinding methods constantly yields new, interesting areas of application, both economically and technically. Applicable for finenesses from 1 to 70 µm (d97).

Machine sizes available for grinding air volumes from approx. 50 to 12,000 Nm³/h.

s-Jet® Steam Jet Mill

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.
