Vibratory finishing machine with annular helical chamber - has downwardly sloping separator sieve underneath with discharge flap at top

摘要

The vibratory finishing machine for grinding and polishing workpieces has a ring shaped chamber with a trough cross section, which follows a descending helical path. The upper part overlaps the lower part, and the separator sieve (25) and delivery opening are at the overlap region. Entry to the sieve is controlled by a swinging flap (27) across the lower end. The pivot axis (28) of this flap is horizontal and radial to the chamber. The sieve surface (25) slopes downwards from this pivot axis.
