ABSTRACT:
An apparatus for recycling waste materials includes a first conveyor for conveying a combination of waste material including magnetic responsive metals, magentic non-responsive metals, glass materials in both large and small particles, and plastics. A magnetic separator is positioned to receive the waste materials from the first conveyor and is capable of removing the magnetic responsive metals. A vibrating shaker screen then receives the waste materials and by virtue of its vibration causes the smaller broken glass to pass through spaces in the screen. Next, an air sorter including a large blower receives the waste materials and blows a stream of air across the waste materials so as to blow the lighter metals, such as aluminum and the plastics away from the remaining large glass materials, such as bottles. The glass bottles are carried away on a second conveyor, and the aluminum and plastics are carried away on a third conveyor.
