Paste Production Storage Mechanism

The Dorr-Oliver® Paste Production Storage Mechanism is a recent development in densification technology to provide a simple, low cost system that allows the production of paste consistency material from mill tailings and other similar granular materials. While the PPSM was conceived for mine paste backfill applications, it is also useful in mineral processing flowsheets for tailings/waste disposal, CCD circuits, high compression thickening and storage.
