METHOD AND SYSTEM FOR INSPECTION AND CLASSIFICATION OF PARTICLES BY GRANULAR PARTICLES Russian patent published in 2015 - IPC B07C5/342 

FIELD: process engineering.

SUBSTANCE: invention relates to sorting of particles, particularly, to process for qualification of ACS for inspection and sorting of particles by feed of preset amount of granular particles to processed flow. Besides, it relates to production and qualification of granular particles that have at least one property, magnitude or range of magnitudes approximating to those of appropriate properties of known undesirable particles. Proposed method comprises the steps that follow. Produced are multiple particles that feature identical shape and size distribution. Conformal surface ply is formed on said particles to get granular particles with coating to impart at least one property with magnitude or range of magnitudes approximating to those of undesirable particles. Multiple granular particles are added to processed flow including multiple particles subjected to processing by inspection and sorting ACS. Said ACS is programmed for selective removal from processed flow of granular particles that feature the preset properties of the range of said properties. Granular particles detected and removed from ACS processing flow are memorised.

EFFECT: better stability and reliability, lower costs, improved testing and calibration.
