ABSTRACT:
An improved vibratory finishing apparatus with a vibratory finishing tub formed like a hollow circular annular trough disposed in a horizontal, ascending- or descending-slope arrangement, the tub having therein a limited accumulating space defined by a known stationary dam of triangular shape at the bottom, a known movable flap member provided with an anti-backflow member thereon, at least one guide plate for guiding a mass including workpieces and media into the space and preventing the backflow of the mass, and at least one closure rigidly or removably mounted on upper open portions of the tub and for controlling the flow of the mass moving up in the space. As a flow of the mass is pushed into the space, it is accumulated to form an accumulated mass which is then pushed out onto the mass separating device or sieve. The space so constructed serves to prevent the backflow of the accumulated mass, and ensures an increased rate of finishing work and a better mass separation.
