Energy-Efficient Vibratory Feeder of Bulk Construction Materials
Any processing of bulk materials requires their moving and uniform feed (dosage). On this depends the quality and efficiency of many technological processes. For uniform and controlled supply of bulk, materials for transporting or processing machines use feeders. Among feeders in recent years, an increasing distribution received disk vibrating feeders, which are characterized by small size, without moving parts, prostate, reliability, accuracy and smooth control supply. Disk vibrating feeder has a horizontal spreading disk, which is located coaxially and with a gap below the outlet of the hopper. Spreading disk is connected with vibratory drive. This research was aimed at finding technical solutions ensuring the reduction of specific energy consumption of disk vibrating feeder. The study showed, that if the spreading disc perform with a central hole, which is closed by an elastic membrane, then this can significantly reduce the specific energy consumption per unit of production.
