A system and method for sizing and separating granular particles within the bulk granular solids by creating a graded granular flow comprising multiple sized fractions with gradation of the particles according to particle size between relatively fine fractions and relatively coarse fractions; and capturing at least a portion of granular flow. The system (11) comprises means (25) for creating the graded granular flow, and means (30) for capturing at least a portion of the graded granular flow. The graded granular flow is split into separate streams, one of which is subsequently captured by intercepting that stream. The intercepted stream may be collected or redirected for further processing.
