5 common faults of sand washing machines

The sand washing machine is indispensable production equipment in the mechanism sand production line. The function of the sand washing machine is to wash off the soil and dust-covered the surface of the sand so that the mechanism sand can meet the standard requirements of construction sand. However, if the sand washing machine is used for a long time, there will inevitably be failure problems. Here are 5 common failure reasons and solutions for the sand washing machine.

1. Sand washing machine broken shaft

There are two main reasons for the broken shaft of the sand washing machine. One is the problem of the shaft itself, such as the quality of the hollow shaft processing material is not good, the strength is not enough, or the hollow shaft is not handled properly during the installation process. Another is the uneven amount of sand returned by the sand washing machine, the uneven operating load of the classifier, or the improper operation of the technicians.

Solution: If the degree of fracture is small, it can be re-welded, and if the degree of fracture is serious, a new hollow shaft can be replaced.

2. Abnormal vibration or sound of sand washing machine

The sand washing machine has abnormal vibration or noise during operation, which may be caused by the blockage caused by the excessive particle size of the material or the improper installation of the sand washing machine.

Solution: stop feeding, wait for the remaining materials to be processed and stop for inspection, and then restart the sand washing machine after confirming that it is correct.

3. The spiral blade or spoke of the spiral sand washer is bent

This may be because the amount of sand returned by the sand washing machine is too large, which blocks the sand returning tank or the screw lift is not enough before the sand washing machine is started.

Solution: replace the new spiral blades or spokes to reduce the throughput of materials and make the spiral reach the specified height.

4. Sand washing machine gears are easily damaged

The sand washing machine is used for a long time, and the gears are damaged after wear.

Solution: Regularly maintain the sand washing machine and replace the new gear.

5. Vibration of the lifting rod of the sand washing machine

The shaft head of the sand washing machine is bent, sand enters the shaft head, and the balls of the shaft head are worn, which will cause the lifting rod to vibrate.

Solution: Clean the shaft head regularly, and check the bending and wear of the shaft head and balls.

The above introduces the causes and solutions of 5 common failure problems of sand washing machines. During the operation of the sand washing machine, attention should be paid to the maintenance and repair of the sand washing machine. Regular maintenance can improve the sand washing efficiency of the sand washing machine. and service life.
