A bulk material processing apparatus (10) which comprises: a longitudinally extending main frame (11); a supply conveyor (23) mounted on, and extending lengthwise of the main frame (11), and operative to convey a supply of bulk material from a forward lower end of the conveyor to an upper and rearward discharge end (24); a material processing device (13) mounted on the main frame (11) and arranged to receive material from the discharge end (24) of the supply conveyor (23), to process the material, and to discharge processed material; a discharge conveyor (32) mounted on the main frame (11) below the processing device (16) so as to be able to receive processed material discharged by the processing device, and to discharge the material to a discharge point located rearwardly of the apparatus; means (16, 17, 18) mounting the processing device (13) on the main frame (11) for movement between a raised operating position to a lowered transport position; and, means (34) mounting the discharge conveyor (32) on the main frame (11) for movement between a raised operative position and a lowered inoperative position; in which the discharge conveyor (32) has a first part (32a) which is mounted on the main frame, and a second part (32b) which is adjustable between an operative position in which it forms a prolongation of the first part, and a folded transport position in which it extends below the first part.
