The coal weighing feeder in the coal grinding system often experiences deviations; how should this be dealt with?
The coal weighing feeder in the coal grinding system often exhibits deviations; as long as these are within the allowable tolerance range, it’s acceptable. If they exceed that range, further parameter adjustments and tuning are necessary, and the problem is likely related to the conveying mechanism and the pressure mechanism.
Generally, it is necessary to calibrate the scale after some time.
Analysis of the reasons for fluctuations in the coal supply amount of the coal feeder: 1) The coal feeder experiences fluctuations up to their maximum level or loses control; there are many possible causes for this, such as damaged bearings in the slip motor, or damaged bearings in the mechanical rolling sleeves of the belt. It could also be caused by severe wear of the gearbox gears, or a broken output connection pin in the gearbox; it might also be due to unstable signals inside the CCS cabinet. Such significant fluctuations can only be resolved by identifying the problem and replacing the faulty components; simply increasing the capacity will not solve the issue. 2) Slight fluctuations in the coal feeder: This situation is more complex ； Unstable signals can be caused by a faulty speed control board or unstable operation of other components in the control cabinet; it may also result from minor damage to the mechanical parts, improper adjustment of the belt, or uneven thickness of the coal layer. The complexity of this situation lies in the unclear nature of the causes. Generally, operating at a reduced capacity can help alleviate and eliminate these fluctuations. The fundamental solution is to readjust the settings of the coal feeder.

Regular calibration also requires adjustment based on the slurry concentration; if necessary, the feeder control should be set to manual mode
Mainly, the weight sensor needs to have the dust on it cleaned regularly, as there are generally no major issues with speed
