| 摘要 |
<p>The invention relates to an apparatus for the separation of heterogeneous waste into a relatively light fraction and a relatively heavy fraction, comprising a vertical or subtantially vertical air duct which is provided with a side opening for supplying the waste, means for drawing air or some other gas upwardly through the air duct and a vibrating conveyor for introducing the waste into the air duct. The vibrating conveyor comprises a conveyor belt, thus preventing the relatively light material from sticking to the vibrating conveyor. Moreover, it is possible to control the supply of the heterogeneous waste more accurately.</p> |
