Abstract

PURPOSE: To control securely the oil content of the regenerated blasting material by regulating the amount of solvent used or the amount of blasting material to be treated in regeneration process of used blasting material with a solvent.
CONSTITUTION: Part of a solvent attached to the blasting material discharged from the cleaner 2 is fed into a percolator 6 to make it transparent, and this transparent solvent is put in an extinctive photometer 7 to measure its degree of extinction. The degree of extinction is proportional to the oil content of the solvent, and there is a known relation between this oil content and the oil centent of blasting material. Accordingly, the oil content of the regenerated blasting material is controlled constant by regulating the feed of blasting material from the foreign matters separator 1 to the cleaner 2 or of solvent from the solvent regenerator device 5 to it 2 on the basis of signals emitted from the extinctive photometer 7 at the stage the degree of extinction gives a constant value.
