How to solve the malfunction of the cold material feeding device in the asphalt mixing plant

There are several potential reasons why the cold material feeding device in the asphalt mixing plant may malfunction. The following steps may help identify and address the issue:

1. Check for Obstructions: The first step is to check for any obstructions in the cold material feeder. It is possible that dirt, debris or other foreign objects may have entered the feeder, disrupting the flow of materials.

2. Inspect the Material Flow: Next, inspect the flow of the cold materials. If the materials are not flowing smoothly, this could indicate a blockage or a misaligned feeder belt. Check the feeder belt tension, if it is loose, adjust it.

3. Check the Feeder Belt: A worn or damaged belt can cause the feeder to malfunction. If the belt is damaged, it should be replaced immediately.

4. Check the Drive System: The drive system of the feeder should be inspected next. A malfunctioning motor, pulley, or gearbox can cause the feeder to fail. Check the motor, gearbox, and belts for wear or damage.

5. Review the Feeder Settings: The settings on the feeder, including the speed and rotation, should be reviewed to ensure they match the requirements for the material being fed. The feeder should be adjusted accordingly if required.

6. Schedule Maintenance: Regular maintenance can help prevent problems with the cold material feeder. It is important to have a schedule set for proper cleaning, lubrication, and replacement of worn or damaged parts.

If the problem persists even after performing these steps, it may be necessary to seek help from a professional to identify and address the issue.
