A machine using such process comprises a rotary vat (101) rotating about a horizontal axis, provided with an axially arranged inlet opening (112), a discharge orifice (115) situated at the periphery of the vat, and a helical baffle (122) for causing a longitudinal displacement of the parts in the treatment chamber (121) of the vat. The vat may be filled during its rotation. It is simply emptied by reversing the rotational direction. The machines of this kind are particularly appropriate for the clipping and the snagging of metal or synthetic castings or for the deburring, degreasing and drying of metal parts. | |
