Abstract: 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).

Abstract: A cereal milling machine having a stock reservoir for incoming stock to be milled, a pair of motor driven feed rolls for metering the stock at a controlled rate from the reservoir, and a pair of grinding rolls for receiving the stock from the feed rolls. A stock level control system comprises a vertical array of spaced capacitive switches located outside the reservoir, each sensor producing an electrical signal according to the presence or absence of stock at the level of the individual sensor, a variable speed motor driving the feed rolls and a micro-computer connected to the sensors and to the motor via an inverter to accelerate or decelerate the motor as a result of changes in the level of stock in the reservoir. The control system ensures a substantially constant mean level of stock in the reservoir and protects the grinding rolls.
