helical conveyor

The screen scroll centrifuge has an advantage of having a driven scroll helical conveyor which gives a small differential speed relative to the conical basket.

The helical conveyor is installed in the centrifuge to control the transport of the incoming feed, allowing the residence time of the solids in the basket to be increased giving enhanced process performance.

In 2003, the firm hired Spooner Industries to supply and fit a helical conveyor – known as a heliveyor – in a bid to reduce wastage by transporting naan from the oven.

Moreover, the helical conveyor and conical basket sections are designed in certain angle of 10 , 15 and 20 being common such that solid particles are dragged on the conveyor along the cone towards the discharge point.
