Abstract: A screening finger assembly having a holder (19) and a set of generally parallel finger tines (16) spaced apart in a row and each mounted in cantilever manner in a respective mounting (20, 22) in the holder (19). Each tine (16) has an outboard end (17), and an inboard end (18) which is firmly clamped in the respective mounting (20, 22). The inboard end (18) of each tine (16) includes a tapered portion. Each mounting includes a mounting bush (20) which is securely mounted in position in the holder (19), and an intermediate load-absorbing sleeve (22) arranged internally of the bush (20) and having an internal surface corresponding in shape to the tapered portion (18) of the tine (16) which it receives. A fastening means (23, 24) moves the tapered portion (18) of the tine (16) axially into firm clamping engagement with the internal surface of the intermediate sleeve (22) to clamp the tine (16) in position.

Abstract: A screening plant having a main frame, a trammel drum mounted on the main frame to be rotatable about a rotational axis at a small angle to the horizontal, and having an input end and an opposite discharge end at a lower end than the input end, screening apertures provided in the wall of the drum, drive means coupled with the drum and operative to rotate the drum while screening takes place, an input hopper mounted on the main frame and arranged to supply bulk material to the input end of the drum, an inclined guide shoot which feeds material from the hopper laterally so as to enter the input end of the drum, and a cantilever type rotatable mounting assembly which rotatably mounts the input end of the drum on the main frame of the plant.

Abstract: There is disclosed an endless conveyor elevator with a foldable support frame, and which has a chassi (3), a tail conveyor section (1) pivotally connected at its tail end (2) to the chassis (3) and pivotally connected at its other end (4) to the lower end of an intermediate conveyor section (5). The upper end (6) of the intermediate conveyor section (5) is pivotally connected to one end of a head conveyor section (7). An actuator (12) is coupled with the conveyor sections to move them between an inoperative folded position, as shown in FIG. 1, to an unfolded rectilinear working position shown in FIG. 2. This movement of the conveyor sections between the inoperative and working positions is achieved by the geometry of the conveyor sections and that of a link member (9) which interconnects the chassis (3) and the head conveyor section (7).
