Apparatus for transporting, agitating, rotating and treating discrete objects, such as metallic parts, has an endless band which is trained over two sets of rollers and forms a trough between the two sets of rollers. The band is driven by at least one set of the rollers and is tensioned at a level below the trough. The objects are admitted into one end of the trough and move up and down in response to movement of the band as well as in a direction toward the other end of the trough, either because the trough slopes downwardly toward the other end or under the action of a helix in the trough. The helix can form part of the band, or it can constitute a discrete part which is rotated in the trough. One or more impellers and/or nozzles are provided above the trough to spray solid or liquid treating agents onto the objects. |
