FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used for clearing articles of dirt, for example, the container for transfer loose and fragile goods. In clearing, hammer pulse impact force is constrained by elastic limit of container shell. Said limit is set experimentally or by calculation to transmit data on amplitude of oscillations produced thereat to rpm controller. Said amplitude is compared with previous magnitude to adjust rpm to amplitude increase to its maximum.
EFFECT: efficient removal of dirt without damaging the container shell.
