In concrete mixing plants, the batching scale weighing system is one of the key components, and its accuracy and stability directly affect the quality and production efficiency of concrete. However, due to various reasons, the weighing system of the ingredient scale may sometimes malfunction and require timely inspection and troubleshooting. This article will introduce common faults that may occur in the batching scale weighing system of the mixing plant and corresponding inspection methods.

1、 Inaccurate ingredient scale

Inaccurate batching scale is one of the common faults in the batching scale weighing system. Possible reasons include sensor damage, poor circuit contact, incorrect settings, etc.

Inspection method:

1. Check if the sensor is damaged, and replace it promptly if any damage is found.

2. Check if the circuit has good contact, and if any poor contact is found, it should be repaired in a timely manner.

3. Check the parameter settings of the ingredient scale to ensure they are set correctly.

2、 The silo does not discharge materials

The failure of the silo to discharge materials is usually caused by sensor failure, silo blockage, and other reasons.

Inspection method:

1. Check if the sensor is working properly. If any abnormalities are found, they should be replaced or repaired in a timely manner.

2. Check if the silo is blocked, and if any blockage is found, it should be cleaned up in a timely manner.

3. Check if the discharge port is unobstructed, and if any debris is found, it should be cleaned up in a timely manner.

3、 Abnormal weighing display

Abnormal weighing display may be caused by sensor failure, signal line connection issues, and other reasons.

Inspection method:

1. Check if the sensor is working properly. If any abnormalities are found, they should be replaced or repaired in a timely manner.

2. Check if the signal line connection is good, and if poor contact is found, it should be repaired in a timely manner.

3. Check the parameter settings of the weighing controller to ensure they are set correctly.

4、 Uneven mixing

Uneven mixing may be caused by incorrect ingredient ratios, insufficient mixing time, and other reasons.

Inspection method:

1. Check if the ingredient ratio is correct, and adjust it promptly if found to be incorrect.

2. Check if the mixing time is sufficient, and if insufficient time is found, the mixing time should be extended in a timely manner.
