► 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.

Dewatering Screen for coal industry

Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.

Working principle:
      To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
      When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

   1. Low noise, easy to maintain
   2. Large capacity
   3. High screening efficiency
   4. Light weight, easy to disassemble and replace
