Abstract
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.
