Question

Thermal reclamation system removes the organic as well as the inorganic binders associated with the sand.

(a) True

(b) False

The question was posed to me in examination.

This interesting question is from Sand Reclamation Techniques topic in portion Sand Reclamation & Control Test of Casting-Forming-Welding II

Answer 1

The correct answer is (b) False

The explanation is: Thermal reclamation systems burn away and remove all the organic binders from the sand, but it does not remove the inorganic binders associated with the sand mass, which are generally fused with the sand grains. Thermal reclamation units can be either electrically operated or gas fired, depending on the degree of reclamation and convenience.
