Weighing Screw Conveyors

Ice is delivered by a screw conveyor into a weighing hopper with load cells and pneumatically operated discharge gate.

This weighing screw conveyor could be placed above the aggregate belt or above the mixer. An advantage of the weighing screw conveyor is the concept of discharging in a controlled and adjustable speed.

It is used to feed the ice through the rotary air-lock valve into the high velocity air stream from the air blower after weighing the ice. Sizes from 300 kg up to 1000 kg are available.
