ABSTRACT:
A regulating apparatus for automatically controlling the production of a minuted mixture having prescribed composition out of big-sized starting materials, comprising starting material flow meters responsive to the rates of flow of the starting materials, a plurality of multiplying devices each having its one input connected to the output of a flow meter responsive to the rate of flow of the comminuted mixture and its other input connected to the corresponding output of a means for determining the concentrations of the controlled components in the comminuted mixture, and a plurality of subtraction devices each having its one input directly connected to the corresponding starting material flow meter and its other input connected to the same flow meter through a delay unit and an a periodic unit. The apparatus further comprises a plurality of adders each having its one input connected through an integrator to the output of the corresponding multiplying device and its other inputs respectively connected through other integrators to the outputs of the subtraction devices. The outputs of the adders are connected to the inputs of the control means for adjusting metering devices which dispense the starting materials.
