Troubleshooting of 5 common faults of spiral classifier

June.18,2020

The spiral classifier is used in the artificial sand production line and the commonly used classification equipment in the washing operation. It is mainly used to wash off the mud powder in the sand so that the artificial sand can reach the standard of construction sand. Some faults will inevitably occur during work and use. Here are some common fault causes and solutions for the spiral sand washer.

Equipment failure repair method

1. Shaft break

The main reasons for the broken shaft are uneven sand return, insufficient strength of the hollow shaft, an uneven operating load of the classifier, poor quality of the shaft material processing, incorrect installation of the hollow shaft or bending of the shaft, and improper operation.
Solution: It can be solved by replacing the hollow shaft or re-welding.

2. Abnormal vibration or noise

When the spiral sand washer is running, the oil is abnormally loud or vibrating.
Solution: Stop the feeding immediately, wait for the remaining materials to be processed, stop the generator, stop the machine and check it, and then restart the operation after the inspection is correct.

3. Bent spiral blades or spokes

Generally, it is due to the excessive amount of sand returning during the operation, which causes the sand returning tank to be blocked; or before the start, the screw lifting is not enough;
Solution: By repairing or replacing new spiral leaves and spokes.

4. Gears are easily damaged

The gears are worn for a long time and cause damage;
Solution: The damaged gear should be replaced in time and maintained regularly, and the sand washer shaft should reach the specified level.

5. Vibration of lifting rod

The shaft head is bent, sand enters the lower shaft head or the ball of the shaft head wears out, which easily causes the vibration of the lifting rod;
Solution: Clean the lower shaft head regularly, and check whether the shaft head is bent and the wear of the balls in time.

The above introduces the common causes and solutions of the five spiral sand washer. In addition to the need to pay special attention to the choice of sand washer, we should also pay attention to the maintenance and repair work of the sand washer. Regular maintenance can be Improving the sand washing efficiency of the sand washing machine can also increase the service life of the sand washing machine. Therefore, the maintenance work of the sand washing machine is essential.
