Fine Sand Recycling Machine

What is Fine Sand Recycling Machine?

Fine sand recycling machine is for slurry material dewatering, de-mediation, desludging development of equipment, through the slurry pump will be the concentration of ≤ 40% of the slurry injected into the hydrocyclone separator for separation, separation of coarse particles into the dewatering screen dewatering and recycling, to solve the problem of fine sand loss in the sand industry, to enhance the utilization rate of resources, to achieve greater benefits!

The main role of the fine sand recycling machine is to wash, dewater and classify sand and gravel, which can well recover a large amount of fine sand lost from the traditional sand washing machine in the sand industry, and enhance the economic benefits while reducing the cost of treatment of tailings and the loss of fine sand will cause pollution and damage to the environment.

Working Principle of Fine Sand Recycling Machine

Pump slurry sand-water mixture transported to the mud and sand high-pressure separator, centrifugal grading concentration of tail sand through the sedimentation nozzle provided to the dewatering screen, dewatering by the dewatering screen, tail sand and water effectively separated, a small amount of tail sand, mud, etc. through the return box and then back to the cleaning tank, cleaning tank liquid level is too high, discharged through the discharge port.

Dewatering screen recycling material weight concentration of 75%-85%. Adjusting the fineness modulus can be realized by changing the pump speed, changing the slurry concentration, adjusting the overflow water volume and replacing the slurry outlet. Thus three functions of cleaning, dewatering and grading are accomplished.

Advantageous features of Fine Sand Recycling Machine

• It also has the function of dewatering and recovering fine sand.
• The cyclone is lined with high-quality polyurethane sieve plate, which is anti-impact and wear-resistant.
• Adopt energy-saving vibration motor, motor and eccentric block with integrated design, use and maintenance is more convenient and fast.

Fine Sand Recycling Machine FAQ

1. Q: What is a fine sand recycling machine used for?
A: It is used to recover, dewater, and recycle fine sand particles (typically 0.2mm – 0.16mm and smaller) that would otherwise be lost in the waste water during sand washing or slurry processing. This reduces material loss, cuts settling pond cleaning costs, and increases final sand production.

2. Q: How much fine sand can a fine sand recovery machine save?
A: A well-designed fine sand recycling system can recover up to 85-95% of lost fines, typically adding 5-15% more finished sand from the same feed compared to washing without a recovery unit. This directly improves your profitability.

3. Q: Does the fine sand recovery machine also dewater the sand?
A: Yes. Most fine sand recycling systems use a hydrocyclone + dewatering screen combination. The hydrocyclone separates the fines, and the dewatering screen removes excess water, producing stackable sand with moisture content typically around 12-18% – ready for transport or further processing.

4. Q: Can I use a fine sand recycling machine with my existing sand washing plant?
A: Absolutely. The unit is designed as an add-on module. You simply connect the overflow slurry from your existing sand washer (screw or wheel type) into the fine sand recovery system. It works with both natural sand and crushed sand production lines.

5. Q: What’s the difference between a fine sand recovery machine and a thickener?
A: A thickener settles all solids for water clarification, while a fine sand recycling machine specifically recovers sand-sized particles (above 75 microns) and dewaters them. For best results, many plants use a recovery machine first, then send the remaining fines to a thickener.

6. Q: What wearing parts need replacement on a fine sand recycling machine?
A: The main wear parts are the hydrocyclone inner lining (usually polyurethane or ceramic), the dewatering screen mesh, and the slurry pump impeller & casing. With proper maintenance and depending on feed abrasiveness, the polyurethane cyclone liner typically lasts 6-12 months.

7. Q: How much water does a fine sand recycling system consume?
A: The system itself is a closed-loop design – it separates sand from water and returns clarified water back to your washing circuit. Actual water consumption is very low (only loss from evaporation and final sand moisture). Most users see a significant reduction in fresh water intake after installation.
