Abstract (en)
[origin: EP0486898A1] With the invention the proposal is made of installing a control on the continuous measurement of the number (z) of impacts of the impact piston or the number (z) of impacts of the impact piston and of the input quantity stream (Qe) into the impact mechanism (6) and to implement said control at an actuator (20) in such a way that if required the internal resistance of one of the two cooperating work units, namely the conveyor unit (3) and the impact mechanism (6) is changed. <??>The control is constructed in such a way that the internal resistance is increased with the rise of at least one of the measurement variables to an adjustable desired value of a performance characteristic variable - with which value a threshold value (z0 and (z/Q)0) which comprises at least the number of impacts is preset. <??>The two aforesaid performance characteristic variables (z) and (Qe) are determined here outside the impact mechanism (6). <IMAGE>
