Abstract
Abstract A rubbish treating apparatus in which the rubbish is gathered, separated, and crushed, after that the crushed rubbish is transferred to a magnetic conveyor, such that ferro-metallic rubbish and non ferro-metallic rubbish are separated. The non ferro-metallic rubbish is then transferred to a pressing device in which the rubbish is pressed, and finally the rubbish is further crumbled and burned in a burner. The gas produced while burning is purified, therefore such procedure can be used to solve the problem of pollution due to rubbish.
