  1. 1. Foundry Sand Reclamation A Presentation by Abhishek.V.Hukkerikar,
  2. 2. 1. Increased interest in reclamation in recent years. 2. Consistent & adequate supply. 3. Uniform properties & characteristics. 4. Delivery cost & delay in maintaining considerable stock.
  3. 3. Background • Economical Increase !! (40% in Purchase & 125% in freight) • Environmental Federal regulations & Chemical Composition of sand • Technical Pre- coated with resin & catalyst & strong grains
  4. 4. Requirements of SR Systems • It should remove lumps. • Removal of magnetic & non magnetic impurities. • Removal of inert organic material. • Good grain distribution. • It should give casting a good finish & appearance. • Removal of fines. • Removal of coatings to a uniform level.
  5. 5. Shakeout Crushing Cooling ScrubbingClassification Storage & mould making Metal Pouring Basic Steps
  6. 6. Types of Reclamation 1. Dry reclamation -No restoration of original quality -Does not remove the organic matter completely 2. Wet reclamation -Partly removes coating -Partly removes organic matter 3. Thermal reclamation -Suitable for oil bonded sands with no clay -Suitable for non-ferrous foundries (Core molding) 4.Combined wet + thermal reclamation -Restores original quality -Removes organic matter completely
  7. 7. The Process Shakeout Bucket conveyor RD1 FBCT1 RD2 FBCT2 CT To Reclaimed sand silo
  8. 8. The Process
  9. 9. Advantages • Offers economic utilization • Self sufficiency • No freight charge & delay • No necessity of bulk inventory • Character specific
