PGD Operating principle
The material to be separated is added into the high-speed rotating centrifuge drum through the feed tube. Under the action of centrifugal field, the material is filtered through the filter cloth, the liquid phase is discharged through the outlet tube, and the solid phase is intercepted in the drum. When the material is full, stop feeding, wash the cake, and filter out the washing liquid. The centrifuge continued to rotate and the cake was dried. After the filter cake meets the separation requirement, the centrifuge reduces the speed and scrapes the filter cake down from the bottom and discharges it out of the machine through the scraper. The centrifuge reduces the speed again, and the pneumatic bag shaking device moves up and down to shake off the residual filter cake, so as to realize the complete removal of the filter cake, thereby realizing the regeneration of the filter cloth.
PGD Main Features
In solid–liquid separation processes, incomplete cake removal can significantly reduce efficiency and increase downtime. This article explains why automatic vertical scraper centrifuges are an effective solution, helping users understand how advanced scraping and bottom discharge designs address common discharge challenges in industrial centrifugation.
