Question

Burning of organic binders can be possible in thermal reclamation systems for reclaiming the sand.

(a) True

(b) False

The question was asked in an online interview.

I want to ask this question from Sand Reclamation Techniques in chapter Sand Reclamation & Control Test of Casting-Forming-Welding II

Answer 1

The correct choice is (a) True

To explain: Thermal reclamation system provides heat to the sand and high temperature is achieved which is enough to burn the organic binders. These systems can be gas fired or electrically operated for the reclaiming of sand. Thermal systems are specifically suitable for organically bonded sands, but the higher temperature gas fired systems can also be utilized for the clay bonded sands.
