Some questions about spiral sand washing machine in South Africa

2021-06-16

The spiral sand washer in South Africais an indispensable piece of equipment in the artificial sand production line. The function of the spiral sand washer is mainly to wash off the mud powder in the sand so that the artificial sand can reach the standard of construction sand. A spiral sand washer will inevitably have some failures in long-term work and use. Below, we will introduce the common failure causes and solutions of spiral sand washers.

1. Broken shaft

The main reasons for the broken shaft are uneven sand return, insufficient strength of the hollow shaft, the uneven running load of the classifier, poor shaft material processing quality, improper installation of the hollow shaft or shaft bending, and improper operation.

Solution: It can be solved by replacing the hollow shaft or re-welding.

2. Abnormal vibration or noise

The spiral sand washing machine makes abnormal noise or vibration when it is running.

Solution: Stop feeding immediately, and after the remaining materials are processed, stop the generator, shut down for inspection, and restart operation after the inspection is correct.

3. Spiral blades or bent spokes

Generally, it is caused by the excessive amount of sand returning during operation, which causes the sand returning tank to be blocked; or the spiral lifting is not enough before starting.

Solution: Repair or replace new spiral blades and spokes.

4. Gears are easily damaged

Gears wear for a long time and cause damage.

Solution: The damaged gears should be replaced in time and maintained regularly. At the same time, the shaft of the sand washer should reach the required level.

5. Lifting rod vibration

The shaft head is bent, sand is inserted into the lower shaft head, or the balls of the shaft head are worn 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 the time.

The above has introduced five common failure causes and solutions of spiral sand washing machines. In addition, the sand washer must be regularly repaired and maintained at ordinary times, which will increase the sand washing efficiency of the sand washer and increase the service life of the sand washer. Therefore, the maintenance work of the sand washing machine is essential.
