Conveyor Spiral Drum – developed for use in situations where the self-cleaning and self-tracking features of the opposing spirals can be considered to be advantageous. As with conventional, tubular drums these are supplied with either a crowned or flat profile.

The conveyor spiral drum scrape the material off the back of the belt and into the cage area from where it is displaced to the outside. Extra deflector plates can also be fitted to ensure a more positive discharge if required.
