Saxlund were chosen by Costain Limited to design, manufacture, and install a dewatered sludge cake truck loading silo and infeed chain conveyor for the Coleshill Sewage Treatment Works near Birmingham.

The truck loading silo is fed by a Saxlund elevating chain conveyor, and is discharged by the Sliding Frame which is fitted onto the baseplate of the flat bottomed silo supported high above the ground.

The Saxlund Sliding Frame reciprocates across the silo floor promoting mass flow and discharges the sludge cake into a screw conveyor. The screw conveyor conveys the material towards the outlet and discharges through a hydraulically operated slide gate valve and into the truck waiting below.
