What is vibrating feeder?

Vibrating feeder is used to feed rocks to primary crushing equipment continuously and evenly in the sand and gravel production line to avoid blockage of the crusher receiving port. In the production process, it can feed the lumpy and granular materials from the storage bin to the receiving device continuously, evenly and regularly, thus preventing the receiving device from dying due to uneven feeding and prolonging the service life of the equipment. Vibrating feeder is widely used in crushing and screening operations in metallurgy, coal mining, building materials, chemical industry, abrasives, mineral processing and other industries.

Working principle

Vibrating feeder is made of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator consists two fixed eccentric shafts whose gears are jogged. When installation, the two gears must be jogged according to the sign. By drive of the motor, the two eccentric shafts start rotating to generate a linear huge power which forces the feeder to vibrate back and forth. Through the vibration, The materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller material will fall down, avoiding the further crushing, so screening purpose is reached.
