Abstract

A rotary kiln is charged with pneumatic tires by a lock chamber which carries two gates adapted to be opened in alternation. To ensure a desirable charging operation, the lock chamber provides a runway downwardly inclined towards the kiln inlet and having a length which is at least twice the tire diameter. The gate at the receiving end of the lock chamber is provided with a tire holder for holding each tire in a position for rolling on the runway. The tire holder comprises a gripping device having two gripping jaws operable to move in mutually opposite directions and engageable with the side wall of a pneumatic tire. The gripping jaws are mounted to be adjustable in a direction parallel to the runway and transversely to the direction of travel of the tire on the runway.
