Course Content

This webinar gives an overview of the state of the art of jet milling technology and tells about advantages of optimized systems with air and steam as grinding media for recovered carbon black (rCB). Due to the parameters it will become clear that new technologies were required on a dynamic market. Motivated out of this, NETZSCH developed two new systems. The economic E-JET® system and the superfine S-JET® system which is operating with overheated steam. It will be shown, that the S-JET® system is not only for super fine applications, but also for very efficient grinding. The advantages will be introduced and the synergy with industries which already have a steam generation on sight will be shown.


After participating in the webinar, participants will:

  • Be familiar with the design of air jet mills with integrated dynamic air classifier for reproducible product quantities and efficient fine grinding of recovered Carbon Black (rCB)
  • Know about advantages and disadvantages of low- and high pressure operation
  • Understand importance and influences of air generation on the process
  • Know about advantages of steam operated jet mills with integrated dynamic air classifier
  • Know about differences between steam and air operation of jet mills by reliable results and performance data
  • Understand the economic impact of process and design parameters of jet mills
  • Understand one of the most important process steps for creating value out of rCB

Target Audience

This course will be most useful to:

  • Tire pyrolysis operators wanting to start creating value out of ELT (end of life tires) and who search for alternatives of selling rCB as waste to secondary fuel usage
  • Technical stuff and plant managers of tire pyrolysis plants
  • Start-ups in the tire pyrolysis industry
  • Engineering consultants for pyrolysis and recycling of ELT
