Sand molds are shaken out by shakeout machine. Used sand is transferred by belt conveyor with magnetic device on it to bucket elevator. Hexagonal sieve crush green sand to fine powder and then fluidized sand cooler cool down sand. And finally >95% foundry sand is reclaimed to sand hopper reservoir for recycling.
Foundry sand is at the very center of sand casting. It can handle the heat of the molten metal, create a huge variety of shapes and details, and be reused again and again. Learn how foundry sand is made, used, and recycled.
· A green sand mixture in a cast iron foundry is characterized by the following properties: • constant particle-size distribution (from 0.1 to 0.4 mm): to obtain a smooth and uniform surface of the metal piece. This property is measured using the thinness index •
Unlike green sand, chemically-bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets its strength through chemical reaction, which is irreversible in nature. Each sand particle is coated with this reacted

Foundry Sand Making Plant and recycling Machine in India with specific casting process. The new raw sands to make casting the waste, most spent foundry sand are of regular sand.
· As foundry sand is an integral part of the casting process, using sand that is too hot or too cold leads to reduced casting quality, with lasting negative affects along the entire production line. When the molten metal is poured into a mold with green sand that is too hot, it can result in higher scrap rates as well as more consumption of bentonite.
Green sand moulds are softer than dry sand moulds. This allows greater freedom in construction when the castings solidify and cool. Green sand moulds are quite strong for small depths, as the gases escape from them. Green sand moulds do not require any backing operations or equipment, but dry sand …
