Pneumatic conveying system for a limestone plant.

Conveying system over a distance of 160 metres horizontal, 30 metres vertical lift with 6 conveying bends.

The system's requirements were to convey very fine and abrasive limestone powder from a silo inside the production building, over a railway line and into the second silo at the railway loading point. The previously installed pneumatic lean phase conveying system was no longer able to meet these stringent requirements.

The Gericke dense phase PTA conveying system provided the perfect solution. Incorporating twin-transmitter vessels it met all the client's production requirements by considerably raising the output whilst at the same time reducing abrasion and wear and also minimising the amount of air required.
