The rotation of the spiral combined with the friction of the trough creates a forward movement. The drive can be pushing or pulling with shaftless spirals or shafted screws. The wear linings are low friction plastic or wear resistant steel bars.

These conveyors can be placed and designed in various configurations to solve transportation of screenings or sludge, inclined, horizontal or even vertical.

The conveyor can also be made as a flush launder. The flush launder uses clean or filtered water that flushes the trough to carry screenings to the compactor or dewatering equipment.
