ABSTRACT:
A method for regulating the material feed to a processing machine, particularly a comminuting machine wherein the actual value of the temperature of the motor winding or windings is measured with the aid of a temperature sensor and is compared in a control regulator with a predetermined theoretical or reference temperature which lies somewhat below the maximum permissible winding temperature of the motor. The difference between the actual value and the reference value effects production of a signal which is applied to an auxiliary regulator for comparison with the actual motor current to derive a reference speed signal for comparison with the actual speed of the aggregate feed conveyor for adjusting aggregate feed.
