What is 'dry reclamation' There are three main types of reclamation systems: Wet, thermal, and mechanical. For the purpose of this editorial, the focus is on mechanical reclamation of silica sand, specifically for ester-cured alkaline phenolic systems. Dry reclamation is fast emerging as the most accepted way to reclaim no-bake systems.
Plans call streamlining coremaking operations and adding new capabilities for future resin systems and alternative materials. The plan is to increase coremaking capacity from 5,000 to 10,000 tons/year. A second goal is to install sand-reclamation as an option for core production.
