Equipment Operation and Maintenance Guidelines: Common Issues and Solutions for Belt Weighing Feeders

The belt weighing feeder is an automated device designed for continuous weighing, metering, and quantitative feeding of bulk materials. It not only enhances production and batching efficiency but also reduces material waste.

Additionally, when integrated with computer management technologies, it provides users with production management capabilities. This equipment is widely utilized across various industries, including coal power, cement, chemicals, environmental protection, metallurgy, building materials, and food processing.

To ensure stable and continuous production, the reliable operation of the belt weighing feeder is crucial. Therefore, proper application, maintenance, and an understanding of common issues and their solutions are necessary.

1. Cleaning of Belt Weighing Feeders

    (1) Promptly remove materials adhering to the scale frame, especially for feeders used in the food processing industry, which require frequent cleaning.

    (2) Exercise caution during cleaning to avoid damaging sensors or other components. Use lowpressure water for rinsing and ensure the power is turned off.

    (3) After rinsing, inspect all signal wires and junction boxes to ensure they are not wet.

2. Material Overflow

    (1) Check the sidewall baffles of the feeder and install additional baffles or use skirted belts if necessary.

    (2) Verify that the prefeeding device is dispensing materials accurately, uniformly, continuously, and at a constant rate.

    (3) Confirm that the belt load is correct and that the shaper height is appropriate.

3. Material Flow Disruption or Blockage

    (1) Disruptions or blockages are typically caused by issues with the prefeeding device, with high moisture content often leading to blockages.

    (2) If the material flow is too large, consider replacing the prefeeding device, such as using a screw prefeeder.

4. Belt Misalignment

    (1) Check if the idlers are operating normally and smoothly.

    (2) Verify that the belt tensioning device is functioning correctly.

    (3) If the belt is excessively worn and cannot maintain constant tension, consider replacing it.

    (4) Ensure that the material load does not exceed the specified limit and feed materials according to specifications.

5. Material Adhesion to the Belt

    (1) Confirm the viscosity of the material and whether the belt can transport it normally.

    (2) Inspect the belt scraper and the cleaning of the return belt.

    (3) Consider adding an additional automatic belt cleaning device.

6. Inaccurate Weighing Accuracy

    (1) Confirm if the zeropoint calibration is accurate. If not, recalibrate.

    (2) Check the feeding flow rate at the maximum belt speed to ensure it is within the specified range and stable.

    (3) Verify that the idler spacing is uniform and use appropriate tools to check.

    (4) Ensure that there are no issues with large mechanical vibrations in the surrounding environment.

7. ZeroPoint Drift, Poor Repeatability, and Poor Linearity

    (1) If the idler spacing is uneven, recheck and adjust.

    (2) Check the weighing bridge frame, head and tail wheels for any stuck materials or foreign objects and remove them promptly.

    (3) Check if the belt is misaligned and adjust it accordingly.

    (4) Check if the connecting bolts of the weighing sensors are loose and tighten them if necessary.

    (5) Check if the connection part of the speed sensor is vibrating, properly contacting the belt, and operating smoothly.

    (6) Check for any stuck materials between the baffles and the belt and remove them promptly.

Numerous practical application cases have demonstrated that understanding common issues and solutions for belt weighing feeders is crucial for quickly troubleshooting problems and maintaining equipment stability.

Additionally, when purchasing a belt weighing feeder, users should consider the manufacturer's aftersales service, including onsite installation and debugging, as well as postsale maintenance. This helps prevent issues that users cannot resolve on their own during subsequent use.

Guonuo Technology, for example, can arrange technicians to provide onsite services according to user needs, ensuring proper installation of the belt weighing feeder and providing training on operation, maintenance, and common issues. They also offer a postsale warranty to safeguard users' subsequent use.
