PDF Cement & Building Materials Conveying - Macawber

The screw pump was introduced for cement handling about 75 years ago. Cement is continuously fed into a high speed screw. The screw is designed so that a pressure boundary is formed between the inlet and discharge of the pump. As the cement is discharged into the pipeline it is fluidised for conveying. The pump screw is powered by a large motor.
