Abstract RU 2236310 C1

FIELD: agriculture, mining, construction and other industries.

SUBSTANCE: invention can be used for sizing round and ellipsoidal products. Proposed riddle is provided with hexagonal calibrating slot-like cells consisting of rigid longitudinal members orientated parallel to axis of movement of riddle case and connected by cross elastic cords. Provision of rigid longitudinal members makes it possible to increase stability of cross sizes of holes and, consequently, accuracy of mixture calibration, and elastic cross members cushion shocks of riddle case on material.
