ABSTRACT:
An improved roller mill construction. Material to be milled or ground such is fed through a discharge opening in a hopper to a pair of cooperating rolls that are mounted within a housing. The discharge opening is enclosed by a sliding gate which is biased to the closed position and can be opened by manual operation of a pull rod. An adjustable setting mechanism is incorporated with the pull rod and enables the gate to be held at an infinite number of open positions. To adjust the spacing between the rolls, the shaft of one of the rolls is journalled within bearing assemblies that are mounted for sliding movement with respect to the housing. A rod is secured to each slidable bearing assembly and is threadedly connected to a shaft which carries a sprocket. By driving the sprockets in unison, the shafts will be rotated to thereby move the bearing assemblies and adjust the spacing between the rolls. The movable roll is mounted for yieldable movement away from the fixed roll by compression springs which are located around the shafts and bear between an abutment on the shaft and the housing. Adjustment of the spacing between the rolls can be accomplished without changing the spring tension.
