The drier the rock is (1–2%), the more dust can be removed, often allowing air classifiers to replace water wash systems altogether. When higher surface moisture is present in stone sand (2.5–3.0%), the fines stick to the rock and larger air classifiers are required with more airflow than usual to be effective.

Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause …
Air classifier working principles involve airflow, classifier aperture, feed rate to air ratio, classifier wheel speed, and size and quantity of classifier blades. A fan generates air velocity and controls the drag force on particles entering this classification zone. Lower airflows permit only finer particles to go through the rejector cage ...
The amount of remaining.phosphate rock reserves and resources worldwide has become an issue of speculation.It has been hypothesized that phosphorus (phosphate rock) production will "peak" in 20033-2034 and then production will unavoidably decrease as the reserves are depleted Because phosphonas is one of the three elements critical to plant …
