What to note when operating a secondary water-washing sand mining vessel. Qingzhou Yongsheng Environmental Pollution Control Equipment Co., Ltd. reminds you:

1. The second washing sand dredger must be flexible in movement and lifting with the bridge frame according to actual working conditions. When挖掘 large rocks and mud with the bucket, they must be manually cleared out.

2. Regularly inspect chain bolts, pins, and all fixed points and fasteners in the drive system.

3. When shutting down, ensure the sand in the hopper is less than 1/2 full, then slowly lift the bridge until the four corner wheels are above water. Once the hopper is sand-free, shut down all pumps, cylindrical screens, conveyors, etc., and then turn off the diesel engine.

4. In the event of strong winds (above 6 levels), the machine should be temporarily shut down to prevent malfunctions. When conducting repairs or replacing parts, the machine should be powered off to avoid any personal injury accidents.
