Abstract
Apparatus for grinding cereal grain involving means for controlling of grinding forces between a pair of cooperating grinding rolls, by regulating the actual grain receiving gap between the rolls during rotation thereof and in accordance with a preset desired dimension. A pair of parallel grinding rolls are mounted for movement of one roll relative to the other in a generally radial direction. One of the rolls is yieldingly biased toward engagement with the other roll. Adjustment mechanism is operative to limit movement of the bias roll toward said other roll and to establish said preset dimension or gap between the rolls.
Claims4
A roller mill comprising:
- (a) a base;
- (b) a pair of tie members;
- (c) means mounting said tie members on said base in spaced parallel relationship;
- (d) first and second grinding rolls;
- (e) a pair of stationary bearings journaling opposite ends of said first roll, each of said stationary bearings being rigidly secured to a different one of said tie members;
- (f) a pair of movable bearings journaling the opposite ends of said second roll and being pivotally mounted each on a different one of said tie members on an axis parallel to the axes of said rolls for free movements of said second roll toward and away from said first roll;
- (g) a pair of levers each pivotally mounted on a different one of said stationary bearings;
- (h) a pair of adjustment members each mounted on a different one of said tie members and each connected to a respective lever to impart movement thereto;
- (i) a pair of connecting members each having portions engaging a respective one of said movable bearings and each having other portions engaging a respective one of said levers for limiting free movement of said movable bearings away from said stationary bearings;
- (j) and yielding means on said connecting members operatively engaging their respective movable bearings to yieldingly hold said movable bearings against movement away from their respective stationary bearings beyond the limit of free movement thereof, said adjustment members being operative to vary the limit of said free movement of said movable bearings in a direction away from said stationary bearings.
