Hands on advice for successful sand reclamation Castings

For a reclamation plant to realise the full value of a sand reclamation system, it must operate at optimal efficiency. Without the careful monitoring of outputs and control parameters in place, the foundry could risk an unacceptably high level of casting defects as well as lost production – and thus revenue. What is ‘dry reclamation’

Introduction Reclamation Systems - ASK Chemicals

Fundamentals of Sand Reclamation The crushing and scrubbing operations are generally followed by an exhaust step to remove lines and then a mechanical device to separate large particles, metallics and various tramp materials. Dry reclamation is emerging as the most accepted way to reclaim nobake systems other than silicates.

Land reclamation in Singapore - Wikipedia

The reclamation of land from surrounding waters is used in Singapore to expand the city-state's limited area of usable, natural land. Land reclamation is most simply done by adding material such as rocks, soil and cement to an area of water; alternatively submerged wetlands or similar biomes can be drained. In Singapore the former has been the most common method until recently, with sand the predominant
