Trouble Shooting Vibratory Feeders 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. (1)Any pitted springs or spaces should be replaced. (2)Reassemble the springs and spaces in the manner in which they were prior to disassembly. (3)Draw up the screw snug. (4)Do this on each remaining banks of springs. ------------------------------------------------------------------------- Henan Pingyuan Mining Machinery Co., Ltd is the most professional manufacturer of Beltconveyor, and Vibrating screen, Bucket elevator, Screw conveyor, Scraper conveyorusing the world's most advanced technology,we are willing to serve every company to meet your custom needs. our goal is "be the futureglobal leader of mining machinery industry". have any questions, please contact us without anyhesitation.

In case the conveying track has no steady running speed or height amplitude, but at the discharge side a higher running speed or height amplitude than on the feeding side, the spring angle has been wrongly adusted to the gravity center angle (See Operating Instructions chapt. 5.2.2) In this case proceed as follows:
In case the conveying track has no steady running speed or height amplitude, but at the feeding side a higher running speed or height amplitude than at the discharge side, the spring angle is wrongly adjusted to the gravity center angle (See Operating Instructions chapt. 5.2.2) In this case proceed as follows:
If the running behaviour is unsteady at a steady conveying track speed and if the material to be transported jumps too much between bearing surface and cover, the gravity center angle and the adjusted spring angle of the total system is too large and consequently the height amplitude too high. In this case proceed as follows:
If the running behaviour is unsteady especially at material to be conveyed with large surface or which is fouled by oil, the gravity center angle and the adjusted spring angle of the total system is too small. The height amplitude is too low. Owing to that the motion of projection cannot take place and in case of oily workpieces the adhesive power is higher than the projectile power, i. e. the workpiece cannot be lifted. In this case proceed as follows:
In case the conveying track cannot be adjusted according to the above mentioned criteria, and, if eg. lateral vibrations or in certain areas dead points occur, the track stiffness is insufficient. The points of impact or separation work towards each other or asymmetrical structural parts of the track lead to unsteady running behaviour. In this case proceed as follows:
