<p>A screening plant (10) which comprises: a main frame (11); a trommel drum (12) mounted on the main frame (11) to be rotatable about a rotational axis at a small angle to the horizontal, and having an input end (13) and an opposite discharge end (14) at a lower end than the input end (13); screening apertures provided in the wall of the drum (12); drive means (234, 236) coupled with the drum (12) and operative to rotate the drum while screening takes place; an input hopper (15) mounted on the main frame (11) and arranged to supply bulk material to the input end of the drum (12); an inclined guide shoot (17) which feeds material from the hopper (15) laterally so as to enter the input end (13) of the drum (12); and a cantilever type rotatable mounting assembly (231, 232, 235) which rotatably mounts the input end (13) of the drum (12) on the main frame (11) of the plant (10).</p> |
