Control of circulation mills, during which the control deviation is decisive for the active intervention on the setting of the material batcher. The deviation is formed by the difference of actual and set values of the circulating material or return fraction, or the ratio of return fraction and the ready product, and it is supplemented by the automatic compensation of the effect in changes in the mass of the milling fill, based on the permanent measurement of the energy input of the drive (11) of the mill (10) and, during a drop of the energy input, the size of the active intervention is reduced and vice versa. The regulatory system consists of sensors (18, 19) of the return fraction and ready product, connected to the block (20) adjusting the actual value of the signal, whose output (22) is connected along with the output block (23) of set values to the regulator (25). The output from the regulator (25) is conducted to the block (28) controlling the active elements of the material batcher (17) in into the mill (10). The regulator (25) is equipped with an additional circuit for setting the amplification, whose steering input (29) is connected to the output (31) of the adaptation block (30), connected by the input (32) to the sensor (34) of energy input of the drive (11) of the mill (10), whereas the adaptation block (30) is equipped with memory of the relationship between the energy input of the drive (11) of the mill (10) and amplification of the regulator (25).<IMAGE>
