► Brief introduction:

Vibrating Feeder is a kind of linear direction feeding equipment, It consists of feed spout, vibration body, vibrating motor, damping device. It can feed material for belt conveyor, vibrating conveyor, bucket elevator, vibrating screen, crusher etc.

► Working principle:The feed process of the vibrating feeder is achieved by the feed spout do line reciprocating vibration periodically which is forced by the special vibrating motor. When the vertical component of the feed spout vibration accelerated speed is bigger than the gravitational acceleration, the material will be upthrow and jumping forward along a parabolic path. Because of the continuous exciting of the vibrating motor, the feed spout will
Vibrating continuously and the material in the feed spout will jumping forward continuously, so that achieves the purpose of feeding material.

► Features:
   1.Smooth operation, large feeding capacity with high efficiency.
   2.Low energy consumption.
   3.Characterized by even feeding, excellent continuity and adjustable vibrating force.
   4.Eccentric block as the main source of vibration.
   5.Double screening and embodies the functions of dirt removing, screening and feeding.

► Advantage:
      Stable vibration, reliable operation and long service life;
      The excitation force and materials quantity moving in the feeder can be adjusted conveniently and easily.
      The vibrating motor, as the excitation source, has low noise, small power consumption, good adjusting performance and without material splash.
      Simple structure, reliable running, convenient installation, light weight, small size, easy maintenance, and the enclosed type can prevent dust pollution.
► Application:
      ZG Vibrating Feeder is a kind of linear direction feeding equipment, which is widely used in pharmaceutical, automotive, electronic, food processing, packaging, glass, steel, construction, recycling, plastic industry etc.

► Operation and Maintenance:
      A.Problems occurring in Vibratory Feeders
Four basic malfunctions that bring attention to vibratory feeders need to be concern:
    1.Declining feed rate due to low amplitude. This will occur gradually over a period of time.
    2.A dead spot in the bowl – parts will not feed past a certain point in the bowl, even though they are moving elsewhere in the bowl.
    3.Intermittent operation. The feeder will spontaneously run at excessive amplitude or possibly no amplitude without apparent cause. Included in this category is for a feeder not to work at all.
    4.Noise from the vibrating feeder.

       B.Overhaul and Readjustment of Vibratory Feeders
   Here are the methods to solve the problems:
       1.Remove the bowl, and clean the mating surfaces between the bowl and the top casting of the base.
      These surfaces can accumulate dirt, sometimes, and other material that will make it difficult to draw the bowl tightly down on the top casting of the base. These surfaces should be flat and clean. Using emery paper or a flat file is adequate to recondition the surface.
      2.Operating on one bank of springs at a time, loosen the springs top and bottom and remove them.
      Both ends of each springs, as well as the spacers and mounting surfaces should be thoroughly cleaned with either emery paper, a wire brush or glass bead shot peened.
    3.Examine each spring for cracks and corrosion
The cracks will always occur adjacent to the hole punched in either end, on this type of spring. Sometimes these cracks are not visible to the naked eye, and a simple test is to hit the spring on something solid (dropping it on the floor). Usually this will cause the spring to break thru.
    - Any pitted springs or spaces should be replaced.
    - Reassemble the springs and spaces in the manner in which they were prior to disassembly.
    - Draw up the screw snug.
    - Do this on each remaining banks of springs.
