A cereal milling machine comprising a base frame (100) to be fixedly mounted on a mill floor and at least one removable roll pack consisting of a pair of rolls (2, 4) mounted in fixed and movable bearing housing (1, 5) respectively and rotatable to form a milling nip. The movable roll bearing housing (5) is pivotally attached at (6) to the fixed bearing housing (1), and an adjustable loading means comprises a handwheel (11) connected via a lever (12), a pneumatic cylinder (13), a lever (9), an eccentric pivot (10) and a top link (7), to the movable bearing housing (5) thus to provide fine adjustment of the milling gap. With this adjustment established the rolls may be thrown in and out of grinding relationship by expanding and contracting the pneumatic cylinder (13). Thus the roll pack combines the micro-adjustment of the milling gap with an engage/disengage mechanism by way of a single compact expandable link in the form of the cylinder (13), and the handwheel assembly (11). <IMAGE> |
