Modern Sand Reclamation Technologies For Economy
main methods of sand reclamation are mechanical attrition reclamation and thermal sand reclamation. In mechanical attrition reclamation, rubbing of sand grains against each other takes place by mechanical means like vibration, fluidisation etc. all the binder coatings cannot be removed by this process.the sand can now be either reclaimed for reuse in the casting process or removed for disposal. thermal reclamation is the most efficient, complete method of nobake sand reclamation. vulcan engineering co. provides a large line of nobake equipment, including mold pouring, mold handling and sand conditioning.pattern casting, and sand casting. the main process divisions for manufacturing castings include molding and casting. molds and cores are the consumable parts of sand casting. for hollow castings cores are needed and after solidification of metal, cores must be removed the figure shows classification of sand molds by molding technology.
