Abstract
In a method for setting the spacings of grinding rollers (2, 2') in roller frames (1) of a cereal milling plant, the roller frames are in each case followed by a screening system (14), from which a test signal is tapped and supplied to a computer (7), which compares it with a stored desired value and in the case of a variation brings about an automatic adjustment of the spacings of the grinding rollers by means of a control signal and adjusting means (4, 5). The test signal is only derived from the screen reject material (17) or screenings (18) of screening system (14) and is only supplied from certain selected key passages to computer (7). In a cereal milling plant for performing this method, a momentum weight measuring system (24, 29, 30, 31) for the continuous determination of the sifting work is associated with the gyratory sifter or sifters (14).
