The fine sand recycling system is a device that specifically solves the serious problem of fine sand loss often encountered in the sand washing operation in the traditional sand making industry. The recycling operation of the fine sand recycling machine improves the sand grading and the economic benefit of the enterprise, so it is widely used. The following 7 lists are the questions that more concerned.
1. Should the sand recycling machine be used in conjunction with the sand washing machine?
The fine sand recycling machine should be used in conjunction with the sand washing machine in the sand and gravel production line. It is mainly used to recover a large amount of fine sand lost from the sand washing machine in the traditional sand making industry after the sand washing machine (it can be more than 20% when the loss is serious).
2. What are the structural components of the fine sand recycling machine? What is the main role?
Fine sand recycling machine is mainly composed of washing tank, slutty pump, motor, cyclone, vibrating screen, and return box.
3. What is the difference between the dewatering type fine sand recycling machine and the ordinary fine sand recycling machine?
The dehydration type fine sand recycling machine has both dehydration and recovery functions. Perform secondary cleaning and dewatering operations on the finished sand washed by the sand washing machine. Perform fine sand recovery on the wastewater discharged from the sand washer.
Dehydration area: composed of vibration motor and dewatering screen. The finished sand of sand washer directly enters the dehydration screen for secondary cleaning, classification, and dehydration.
Sand recycling area: composed of high-pressure slurry pump, motor, separator, return tank, and cleaning tank. The sand-water mixture discharged from the sand washer enters the cleaning tank and is sent to the cyclone separator via the pump to separate the sediment and extract the fine sand. Then the fine sand enters the dewatering screen to dehydrate. Other impurities pass through the overflow port of the separator and enter the return tank to be discharged.
4. What is the main difference between fine sand recycling machine and sand washing recycling machine?
Basically, the sand washing and recycling machine is composed of two main parts: the wheel sand washer+sand recycling machine. But the sand recycling system only has the recycling part.
5. What is the reason for the sudden reduction of fine sand recovery?
If find that the amount of fine sand recovered is significantly reduced or there is a lot of sand leakage, check whether the screen is broken or the bolts fixing the screen are loose. The treatment method is to change a screen or tighten the bolts.
6. What other methods can be used to recycle fine sand besides sand recycling system?
Multi-stage sedimentation tank, equipped with dewatering sieve, adding chemical agent, equipped with sand washing and recycling machine integrated machine for fine sand recovery.
7. What to do if the frame of fine sand recycling machine vibrates?
Frame vibration may be caused by loose bolts on the connecting frame or bearing housing. The remedy is to tighten the bolts and check carefully.
