Vibrating Grizzly Feeder Specs

Vibrating Grizzly Feeder Common Fault Handling

1, No-Load Test Is Normal, The Amplitude Is Reduced During Production

After the Vibrating Grizzly Feeder is in the normal test, the amplitude is reduced and the working efficiency is low during normal production. It is likely that the feeding port of the equipment is improperly designed, and the tank of the equipment is subjected to excessive load and pressure. At this time, it is necessary to improve the feed port in time, reduce the feed pressure of the equipment, and ensure that the equipment works in a stable production environment.

2. After The Power Is Turned On, The Device Does Not Vibrate Or Work Intermittently, And The Current Is Unstable.

Vibrating Grizzly Feeder vibration motor fuse blown or coil wire short circuit will directly affect the normal operation of the equipment, resulting in vibration feeder does not produce vibration, it is necessary to replace the new fuse in time, check the coil motor layer or turn of the vibration motor To eliminate the short circuit, connect the lead line.

3, The Vibration Amplitude Is Small, The Shaker Can Not Adjust The Amplitude Normally

After the Vibrating Grizzly Feeder is powered on, the device does not vibrate or work intermittently, and the current is unstable. This is the case when the exciter thyristor is broken down by excessive voltage and current, or the air gap between the components of the device is blocked by excess material. It is necessary to clean the clogged material in time and replace the shaker thyristor. It should be noted that after the long-term operation of the Vibrating Grizzly Feeder, a short circuit occurs between the solenoids of the thyristor, and the rectifier of the thyristor is burned, causing the equipment to stop, and the electromagnetic coil of the thyristor needs to be replaced in time.

4, Noise And Impact When Working

When the amplitude of the device is irregular, an abnormal impact is likely to occur.

If the plate spring of the Vibrating Grizzly Feeder breaks, or the connecting bolt of the exciter and the tank is loose, the vibration of the equipment will be irregular. It is necessary to tighten or replace the new connecting bolt and spring structure in time, and keep the equipment parts such as iron core. There is a certain air gap between the armature and the armature. At the same time, it is necessary to adjust the motor control to maintain the rated working voltage to avoid collision and voltage instability of the machine components during the vibration process.

5, The Vibration Feeder Amplitude Is Abnormal

1. When the rated voltage is unstable, the thyristor in the vibrator of the Vibrating Grizzly Feeder will be broken by excessive current, and the short circuit will occur between the electromagnetic coils. In severe cases, the thyristor will be burned. The amplitude cannot be adjusted. Therefore, to ensure the stability of the rated voltage of the equipment, at the same time replace the burned electromagnetic coil or thyristor, check whether the connection line of the thyristor is connected correctly, and whether the over-current protection works normally.

2. In order to keep the Vibrating Grizzly Feeder from running when the components do not collide with each other, a certain gap is left between the components during installation. When the material is transferred, sometimes the material will jam in the gap of the device and cause the blockage. At this time, the exciting force will be restricted, which will cause the amplitude adjustment to be abnormal. Therefore, it is necessary to keep the material transfer normal, clean the stuck materials in time, keep the Vibrating Grizzly Feeder running normally, and the amplitude adjustment is flexible and reliable.

6, No Feeding Or Insufficient Feed

Cause Of Issue:

  • The silo load squeezes the feeder chute, causing fatigue damage or breakage of the spring plate and the connecting fork;
  • Too much feed, causing the material to accumulate in the machine base, the resistance of the screw conveyor is increased, and the hopper is not running smoothly;
  • The vibration amplitude of the feeder is small, and the shaker cannot adjust the amplitude normally. The exciter thyristor is broken down by excessive voltage and current, or the gap between the components of the device is blocked by excess material;
  • The iron core and the armature air gap are not in the range of 2.0±0.1mm, which is too large or too small to affect the feeding capacity.

Solution:

  • Note that the feed port and the discharge port of the trough cannot be fixedly connected with other equipment, but the chute should have a certain swimming range so that it does not affect the normal amplitude of the Vibrating Grizzly Feeder;
  • Reduce the amount of feed immediately and keep the feed even;
  • Clean the clogged material in time and replace the shaker SCR;
  • Make an appropriate adjustment to the air gap.

In the operation of the Vibrating Grizzly Feeder, in addition to the faults to be repaired in time, it is necessary to strengthen the daily maintenance work. Reasonable maintenance can effectively reduce the wear and prolonged service life of the Vibrating Grizzly Feeder.
