Pyrolysis System

1. The pyrolysis process employs an atmosphere rotary furnace, where crushed battery materials are dynamically and uniformly heated under inert gas protection to complete electrolyte volatilization, separator/PVDF decomposition and dissociation of black powder from electrode sheets;

2. Tail gas generated during pyrolysis undergoes high-temperature dust removal (to collect black powder) before entering a TO for combustion treatment;

3. The atmosphere rotary furnace is not only applicable for pyrolysis of crushed battery materials but also suitable for reduction or oxidative roasting of electrode powders.

Product Feature

Aiming at the special needs of lithium battery recycling industry, the rotary furnace has been optimized and upgraded in several key technical aspects such as material propulsion and conveying, sealing performance and corrosion resistance.

1. Stable and efficient material propulsion and conveying capacity ensures the stability of pyrolysis time.

2. Multi-stage sealing technologies including packing, end face and air ring effectively improves the sealing performance of the rotary kiln.

3. Preposed electrolyte volatilization, reliable sealing and corrosion-resistant composite materials enhances corrosion resistance and extends the service life.
