Quarry By-Products - Material Description - User

Screenings are a uniformly sized, fine, sandy material with some silt particles. Screenings commonly range in particle size from 3.2 mm (1/8 in) down to finer than 0.075 mm (No. 200 sieve). Normally, the percentage of particle sizes finer than 0.075 mm (No. 200 sieve) is 10 percent or less by weight. Stockpiles of screenings may contain some particles up to 4.75 mm (No. 4 sieve) in size, which

Dewatering Screens | McLanahan

Dewatering Screens can be used to dewater -4 mesh (5 mm) particles of sand, coal, iron ore, salt, etc. They can also be used to dewater fines in fines recovery circuits, typically +400 mesh (+38 µm), as well as to rinse and dewater jig discharge — nominally -2" (50 mm). Dewatering Screens can be used for limited efficiency fine sizing at or above 10 mesh (2 mm) to create differential

Beneficial Uses of Spent Foundry Sands |

Beneficial Uses for Spent Foundry Sands. EPA's risk assessment for the beneficial uses of spent foundry sands found that that silica-based spent foundry sands produced by iron, steel and aluminum foundries can be safely reused to save energy, reduce the need to mine materials, and reduce costs for both producers and end users. EPA supports the use of silica-based spent foundry sands
