FIELD: sampling of comminuted loose materials given to dusting, ground sinter of alumina production included. SUBSTANCE: proposed sampler of loose material has sampling box mounted on ends of levers-rockers for turning-over that are anchored with one ends on immobile axle and actuating mechanism. Length of levers-rockers is determined by expression l ≥ 3.82 h, where h is depth of flow of material at point of sampling. EFFECT: enhanced operational reliability of sampler. 3 dwg
