A Method and a Device for Reclaiming Green Waste Foundry Sand
Abstract

Disposing of waste foundry sand (WFS) is a major challenge for the foundry industry today. Utilizing reclaimed sand within the foundry can enhance the economics and efficiency of the process while reducing environmental impact. This invention aims to reclaim waste foundry sand using a two-stage attrition device designed to recycle WFS, allowing it to be reused for making molds and cores.

Societal Impact

Helps in prevention of air and groundwater pollution by reclaiming waste sand efficiently in a cost-effective manner

Salient technical features and Advantages of the Technology
  • Reclaims waste sand at rates as low as 50 kg/hr 
  • Minimizes the need for thermal treatment which is usually required in conventional methods 
  • Uses only mechanical methods to reclaim green sand 
  • Significantly reduced reclamation costs makes the process much more affordable compared to traditional high-temperature treatments 
  • Eliminates the need for high-pressure treatments and fluidized beds 
  • Suitable for large-scale foundries, as it can be easily scaled up due to its simple construction, compact design, and cost-effectiveness
