Pyrolytic cleaning works on the principle of material degradation which is deposited on the surface of the screw. When burning is complete, the screw is only mechanically cleaned. The process is running in the vertical position, therefore, there is no deformation of the screw.
Process of burning is completely automatic and operation of the device does not require any operator attendance.
Burning time is 3- 8 hours depending on the size of the screw and the degree of the pollution.
The process temperature is set between 400 and 500 °C.
Suitable for all thermoplastic materials.
Device is equipped with a water tank in which gases from burning are collected by using a water ring pump.
