There is disclosed a device for chopping-up bulk material and particularly long stem animal feed material and which comprises: a frame (11); an elongate cutter body (12) mounted in said frame (11) for rotation about a substantially horizontal axis; cutter blades (14) mounted on the outer periphery of the cutter body (12); an elongate housing (15) extending partly around said cutter body (12), said housing defining an inlet (16) which extends substantially throughout the length of the cutter body to admit bulk material to be chopped and an outlet (19) for discharging chopped up material after treatment by the blades (14) of the rotating cutter body (12); a feeder device (20) arranged on the frame (11) and operable to support and to feed the bulk material to the housing inlet (16); and, a grill (22) arranged at the inlet (16) so as to control the supply of material to the cutter body (12). The grill (22) comprises an arrangement of grill bars (23) which are spaced apart so as to define spaces (24) through which the cutter blades 14 can move during rotation of the cutter body (12), said grill bars (23) and said cutter body (12) being relatively adjustable so as to permit variation in the extent by which the cutter blades (14) project beyond the grill bars (23) during rotation of the cutter body (12), so that the device can be readily adjusted to treat different types of bulk material. |
