Spirotech-SRD has recently built and delivered another high-end pressurised screw conveyor for its continuously expanding overseas market.
This pressurised screw conveyor is designed to operate at 1.3 bar pressure (nitrogen) and also to contain any internal explosion. It has been designed for a conveying rate of 124 metric tons per hour and it will also operate 24/7 with minimal maintenance as the screw is of the single span type so that the only maintenance required is external on the bearings and shaft seal housings. Had the client requested mechanical seals for the shafts then the maintenance would have been carried out annually.
Spirotech research and development meets high demands of its clients
Spirotech has now eliminated the need for hanger bearings and are regularly manufacturing single span screws up to 9 meters in length for the high-end market place which require a maintenance free operation. With Spirotech’s proven track record over the last 35 years this pressurised screw conveyor is expected to run 10 to 15 years with no mechanical issues. The Spirotech team continues with its research and development to meet the high demands of its clients for reliability and service.
