Abstract: The invention proposes a novel automatic product feed in which an analog signal is formed and at least one other digital signal which is adjustable independently of the analog signal is generated and used for the automatic product feed for supervising the product feed functions by a mechanical probe (8) in the product flow. In this way, all previously known controlling and regulating functions can be realized with a minimum of electronics or at the highest level of computer control as a function of the product feed or for optimizing the grinding conditions, possibly with externally initiated digital signals for various stage adjustments and with the use of very simple automatic component means. The invention further proposes a corresponding method for grinding with a milling roller mill (1).

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.
