The sand washing machine is essential production equipment in the machine-made sand production line. The sandstone washing machine can not only wash away the soil and dust covering the surface of the sand but also has a low loss rate of fine sand and stone powder. The stone that has been cleaned by the sand washing machine can meet the national construction sand standards to meet the diverse needs of users. However, if we use the sand washing machine for a long time, it will malfunction. Today, I will introduce the common faults and solutions of sand washing machines.
1. Abnormal vibration or noise in the sand washing equipment:
Causes: the particle size of the material is too large; the blockage is caused by improper installation of the sand washing machine.
Solution: Stop feeding, stop the machine to check after processing the remaining materials, and then restart the sand washer after confirming that it is correct.
2. The frame of the sand washing machine vibrates
Cause: the bolts of the connecting frame are loose; the bolts of the bearing seat are loose
Solution: Check and tighten the bolts.
3. The sand ore washing machine makes repeated noises
Causes: lack of lubricating oil in the bearings of the sand washing machine; damage to the bearing steel ring; impurities or wear in the bearing.
Solution: Add an appropriate amount of lubricating oil to the bearing; replace the bearing sealing ring; regularly clean and maintain the bearing.
4. The amount of sand washed by the sand washing machinery is decreased or the sand is leaking
Cause: The sand net of the sand washing machine is damaged; the fixing bolts of the sand net fall off
Solution: check and repair or replace with a new sand net; tighten bolts
5. Worn or damaged gears of sandstone washing equipment
Causes: Do not pay attention to daily maintenance and lubrication; the shaft of the sand washing machine for mining does not reach the specified parallelism.
Solution: add lubricating oil to the gear regularly to ensure the lubrication of the gear and increase the utilization rate of the gear; adjust the shaft of the sand washing machine to the specified standard
Correct operation and maintenance of Sand washing machine:
1. Before starting the sand washing machine, the operator should check whether enough grease has been added to each lubrication point and tighten the connecting bolts.
2. After starting the motor, wait for the machine to run normally, turn on the water pump first, adjust the water flow, and then start to feed gradually.
3. Stop feeding before the machine stops running. After all the materials in the tank are exhausted, make sure that there is no material in the water tank before stopping the machine.
4. Regularly check the abrasion of the blades of the sand washer, and replace the blades with a greater degree of wear in time to avoid affecting the efficiency of the machine.
5. Regularly open the bearing cover of the sand washer to check the wear of the bearing and replace it in time.
The above are the common faults and solutions of the sand washing machine, and how to operate the sand washing machine normally. In the operation of the sand washer, paying attention to daily maintenance and maintenance can make the sand washer have a longer service life, thereby improving the working efficiency of the sand washer.
