The waste type processing method includes three processes of tyre crushing, thermal cracking and carbon black crushing and packing. During the tyre crushing processes, waste type is first-crushed in pre-crusher and washed, and then crushed for the second time into rubber grains below 25 mm size. During the thermal cracking process, the rubber grains are thermally cracked in thermal cracking furnace at 480-700 deg.c and 0.01-0.04 MPa negative pressure, the gaseous product is condensated and cooled in washing tower to obtain fuel oil, the uncondensated light components is reused as fuel gas in the furnace and excessive inflammable gas is for heat energy conversion to provide hot water. In the carbon black crushing and packing process, the mixed material of carbon black and steel wire obtained in the thermal cracking process is magnetic separated and the carbon black is ground and packed as product. |
