Optimizing screen parameters. Detail analysis. Roller screens are our specialty, mainly in the area of mineral (iron ore) processing. Thanks to WooDEM and custom-developed pellet contact model, we can capture results from these complex machines quantitatively. Screen types ¶ Screens segregate feed into 2 or 3 resulting streams:
3 Screening machines for iron ore and coal. The crushing and screening systems for iron ore processing vary widely, depending on whether a magnetite or hematite deposit is being mined. While good quality magnetite is now dry-processed, hematite from deposits below the water line requires wet processing due to sticky quartz and clay contaminations.
The roller screening process is a probabilistic process depending on the movement of the green pellets over the equipment, screen deck inclination, particles orientation (if not …
