Dry process for recycling rubber waste

摘要

A dry process for speedy and continuous treatment of discarded or used rubber waste is disclosed wherein discarded rubber waste is pulverized into particles of 20-40 mesh and is transmitted to an air tight vessel in which the pulverized rubber waste is indirectly preheated at a temperature between 100 degrees-200 degrees C.; and is then delivered to a fast reactor in which many additives, such as process oil, minerals, rosin and zeolite, are blended with the pulverized rubber waste. The mixture is further stirred by way of a motor to permit the process oil to effectively penetrate into the pulverized rubber waste; and is finally refined to get useful recycled rubber material.
