GTI - Thermal Sand Reclamation and Mechanical Sand

Thermal sand reclamation was an exotic option for foundries and the Gudgeons wanted to develop a machine that was compact, unique in design with a low thermal mass, fuel efficient, easy to maintain and affordable. Out of this ambition Thermfire was born. The Company invested in a prototype and installed it in their London plant.

Fundamentals of Sand Reclamation - Home: ASK Chemicals

2015-8-25 · When chromite sand is reclaimed, or is present in the reclaimed silica sand system, it required special attention. Normally, chromite sand is used in combination with silica sand to produce surface chill or to promote directional solidification. During the recycling steps of the reclamation process, the chromite and silica become thoroughly blended unless some separation device is used.
