Energy-Efficient Vibratory Feeder of Bulk Construction Materials

Abstract

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.

Energy-Efficient Devices for Transporting and Feeding Bulk Materials in the Construction Industry

“…In the work [35] the energy-efficient design of the disc vibratory feeder is proposed. The spreading disc is formed with a central hole, overlapped with elastic membrane.…”

Energy-Efficient Technology Supply Bulk Materials

“…To reduce the specific energy consumption allows the vibrating feeder of loose materials containing fixed base of the feed hopper and installed under his exhaust pipe solid plate and at least one distribution plate with a Central hole. Distribution plate located between the outlet and the solid plate attached to the vibrator and connected with a solid plate by means of elastic elements [15,16]. This is equivalent to the diameter of the distribution plate must be equal to 0.6 to 0.9 equivalent to the internal diameter of the exhaust pipe feed hopper.…”
