Product introduction
???? Fine sand recovery machine, also known as fine sand recovery device, fine sand extraction machine, tailings recovery machine, etc., is often used for the recovery of fine sand in waste water discharge of sand washing production line. The last process of artificial machine-made sand production line is usually to clean the sand by sand washing machine. In the process of sand cleaning, a large number of fine sand (particles less than 0.25 mm) will be washed away by water, resulting in serious loss of fine sand The effective fine sand reclaimer can recover the sand washed away by water and reduce the economic loss caused by the loss of fine sand.
The advantages of fine sand reclaimer are as follows: 1) reducing the loss of fine sand and reducing the treatment capacity of discharged sludge; 2) the recovered fine sand can increase economic benefits; 3) there must be a certain proportion of fine sand in the sand to make the sand grading more reasonable; No matter what kind of sand washing machine is used, most of the existing sand washing machines have serious loss of particles (less than 20.5 mm). This not only lost the output, but also seriously affected the grading of sand, resulting in unreasonable gradation, increased fineness modulus and greatly reduced the product quality of manufactured sand. In the process of concrete mixing, not only the amount of cement is increased, but also the cost of budget is increased. Moreover, excessive discharge of fine sand will cause waste of land resources and environmental pollution. In view of the above problems, our company has successfully developed a professional fine sand recovery equipment - AQS fine sand recycling machine. This equipment is a high-tech environmental protection equipment specially designed by our company to absorb advanced fine sand recovery technology at home and abroad, combined with the serious loss of fine sand in the actual production of customers.
working principle
??? The mixed water is discharged into the reservoir, and the special centrifugal slag pump pumps the sand water mixture in the reservoir to the hydrocyclone. The fine sand concentrated by centrifugal classification is provided to the vibrating dewatering screen through the sand setting nozzle. After dewatering by the vibrating screen, the fine sand and water are effectively separated. A small amount of fine sand and mud are returned to the cleaning tank through the return water tank to mix with the mixture returned from the hydrocyclone and then sent to the hydrocyclone for separation. When the liquid level of the cleaning tank is too high, it will be discharged through the water outlet. The fineness modulus can be adjusted by changing the speed of centrifugal pump, changing the concentration of mortar, adjusting the overflow water volume, and replacing the sand nozzle, so as to realize the three functions of cleaning, dewatering and grading.
Fine sand recovery machine can be widely used in: artificial sand field, sand washing field, secondary processing enterprise of mine stone powder, marble processing plant, tailings slag treatment, commodity concrete company, sand absorption of wharf and other industries.
Highlight advantages
Reduce the loss of fine sand, reduce the amount of wastewater treatment
The fine sand is recovered and the subsequent workload of wastewater treatment is reduced.
The recovery rate is high and the economic benefit is increased
It can recover 85% of the lost fine sand and greatly increase the economic benefit.
With the increase of fineness modulus, the sand gradation is better
The recycled fine sand can increase the fineness modulus and make the sand grading better.
Less investment, faster results
It has the advantages of less investment, simple operation, faster return to cost and outstanding later benefit.
