Dynamic analysis of vibratory feeder and their effect on feed particle speed on conveying surface

The vibratory feeder is a forced vibrating system mostly used in industries to feed material from hoppers, bins, silos and storage piles to belt conveyors. It is used to control the feed rate of material being transported. In this paper, dynamic analysis of the vibratory feeder is conducted theoretically and the obtained results are validated with experimental values corresponding to the various operating frequencies of the feeder unit. Further, speed of feed particles are identified experimentally at various operating frequencies. The actual vibration behavior of the particle on conveying surface is examined experimentally and movement of the particles are shown graphically. The experimental work is conducted on the fabricated vibratory feeder with 1HP motor installed on it with variable speed controller. The instruments used are the B&K 4-channel analyzer, accelerometer and the force transducer. The post processing of data analysis was done in ME'Scope software.
