Automatic Devulcanizing and Plasticizing Device and Method for Using Same

摘要

Rubber to be recycled is first ground to rubber crumb and then is transferred to a plasticizing unit. The rubber to be recycled is mixed with chemicals including an aromatic, environmental-friendly, low volatility reaction oil, a thickening agent and an activator. This mixture is heated to a desired temperature under anaerobic conditions and then is maintained at that temperature for a suitable time. The processed material is then transferred to a cooling unit in which it is cooled to a temperature below 60° C. prior to being released from the machine.

主权项

1. A method of recycling rubber comprising:
(a) grinding a quantity of rubber to be recycled to a particle size between −10 mesh to-40 mesh, thereby producing rubber crumb; (b) providing a rubber plasticizing machine comprising a plasticizing unit comprising a plasticizing conveyor and a cooling unit comprising a cooling conveyor; (c) transferring the rubber crumb into the plasticizing unit; (d) mixing the rubber crumb with chemicals, thereby producing a mixture, said chemicals comprising a reaction oil, a viscosity increaser and an activator; (e) heating the mixture in the plasticizing unit to a temperature between 200-250° C. and maintaining the mixture at said temperature for a predetermined period of time; (f) transferring the mixture from the heating unit to the cooling unit; (g) cooling the mixture in the cooling unit to a temperature below 60° C.; and (h) releasing the mixture from the cooling unit.
