Pre-separation phase: Since not all material is being pushed through the front sieving plate in position 1, the second step is to pre-separate larger rock fragments (first step of size separation). In this position, which orientates the front sieving plate horizontally, both spring-loaded gates are still closed, and the vibration motor starts operation to facilitate size separation. Once there is no more material present on top of the screen, the vibration motor stops, and the mechanism moves into position 3 where both the inlet and arm are at the same angle of ~ 45°.
