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).
