An adjustable splitter assembly at any position along the spiral trough and the splitter is angled to a fixed position pressed against the trough and locked against movement by a long arm selectively clamped in one hook of a retainer having spaced hook sockets, the retainer being attached to the outer rim of the trough either upstream or downstream from the splitter. The splitter may be angularly adjusted to position its leading edge at different locations along an arc with respect to the stream of particles flowing down the trough by moving the arm to another selected hook socket.
