<p>In a spiral separator of the kind used for the wet gravity separation of solids (Figs. 5 /A 6) there are provided splitters (70,71,72) in troughs (20,21,22) which are operatively connected by means (80) permitting adjustment of splitters in unison. Preferably the splitters are at corresponding locations of separate troughs and are in vertical register.</p> |
