Fine Sand Recovery Unit FAQ

The function of the fine sand recovery unit is to recover a large amount of fine sand lost by the sand washing machine and improve the sand gradation, so it is widely used. About the fine sand recovery units, there are 6 questions that are often asked.

1. Is the fine sand recovery unit used in conjunction with the sand washer?

In the sand and gravel production line, the fine sand recovery unit is mainly used to recover a large amount of fine sand lost by the sand washer (more than 20% when the loss is serious) after the sand washing machine. It not only improves the economic benefits, but also reduces the pollution and damage to the environment caused by the loss of fine sand.

2. What are the structural components and main functions of the fine sand recovery unit?

The fine sand recycling machine is mainly composed of a washing tank, cyclone, slurry pump, motor, vibrating screen, return box, etc. The main function of the fine sand recovery system in the sand and gravel plant is to separate and recover fine sand. The main function of the concentrator is tailings recovery, so it is also called the tailings recovery machine.

3. What is the difference between the dewatering fine sand recovery unit?

The dewatering fine sand recycling machine has two functions dewatering and recycling. It can carry out secondary cleaning and dewatering operations for the finished sand of the sand washing machine, and fine sand recovery for the wastewater discharged from the sand washing machine.

4. What is the reason for the sudden decrease in sand recycling?

When the amount of fine sand recovered is significantly reduced or a large amount of sand is leaked, check whether the screen is broken or the bolts fixing the screen are loose. The solution is to replace the screen or tighten the bolts. When the screen mesh is worn too seriously, it will lead to the phenomenon of a broken screen, which will reduce the recovery efficiency. Therefore, the screen mesh must be checked regularly and replaced in time after wear.

5. Are there other ways to prevent fine sand loss?

It is also possible to use multi-stage sedimentation tank precipitation, equip with a dewatering screen, add chemical agents, configure sand washing and recovery machine integrated machine, and other methods for fine sand recovery. When configuring a sand washing and recycling integrated machine, it is not necessary to add a separate sand washing machine.

6. What should do if the frame of the fine sand recovery unit has vibration and noise?

The vibration of the frame may be caused by the loose bolts on the connecting frame or the loose bolts on the bearing housing. The troubleshooting method is to tighten the bolts and check them carefully. The noise may be caused by the gear spacing change, generally, add enough grease, adjust the reducer anchor bolts and tighten them. In addition, the damaged bearing and the breakage of the screen carriage will also produce noise, and the bearing or screen carriage needs to be replaced at this time.
