Discarded tyre is shredded into smaller cubes, after the removal of bead wire, steel wire, and nylon chord. The shredded pieces undergo further size reduction through set of pulverizers cost effectively wher the power consumption per ton of waste tyre is only 30 kilo watts per hour. Once the size is brought out to 30 mesh size through a unique pneumatic conveying system and passed on to a specially manufactured Finned Jacketed, Screw Conveyors. The heat energy required for the pyrolysis reaction is supplied by a hot air generator fuelled by the non-condensable gases evolving from the pyrolysis reaction.
