Question

In the dry reclamation system, a strong metal plate is used on which used sand is blasted to get converted into fine powder.

(a) True

(b) False

This question was posed to me by my college director while I was bunking the class.

My question is based upon Sand Reclamation Techniques in division Sand Reclamation & Control Test of Casting-Forming-Welding II

Answer 1

Right option is (a) True

The best I can explain: Dry reclamation process crushes the sand lumps into grain size, and then the binders are removed from the sand grains by the use of mechanical abrasion. Released fines particles are separated and then dry sand is prepared by crushing the sand to the metal plate by blasting which removes all the metal particles and the resulting fines are taken to a dust collector.
