The only moving part contacting material is the inner screw, which self-centres as it rotates, providing ample space between the screw and tube wall to minimise or eliminate grinding. The lower end of the screw requires no bearing, while the upper end is driven beyond the point of discharge, preventing material contact with bearings or seals.
Fully enclosed, the conveyor tube prevents product and plant contamination, while the gentle rolling action imparted by the screw prevents the separation of blends.
Available with an optional start-stop control panel and a range of flow-promotion devices, the product is also available on a Quick Ship basis in the Americas and in Europe.
