double wheel sand washing and fine sand recovery machine

Double wheel sand washing and fine sand recovery integrated machine is optimized and designed on the basis of traditional wheel sand washing, which realizes the segmented washing of sand and gravel materials through the double impeller system, and at the same time combines with high-efficiency dewatering screen and fine sand recycling device, which reduces the loss of fine sand, improves the quality of finished sand and gravel products, and enhances the utilization rate of resources.
It is widely used in artificial sand production line, washed sand system, mechanism sand shaping and recycling process and all kinds of environmentally friendly sand and gravel aggregate plants, and is one of the important washing and recycling equipment for the current green building materials production.

Features of double wheel sand washing and fine sand recovery integrated machine:

1. integrated structure design: organic combination of sand washing system, dewatering screen, fine sand recovery system, small footprint, easy to install, easy to integrate into various types of sand and gravel production lines.
2. Double-wheel high-efficiency cleaning: Adopting two sets of impellers running in series before and after, the first cleaning removes large particles of soil and impurities, and the second cleaning further finely washes and effectively reduces the content of mud and powder.
3. customized screen configuration: the screen is made of polyurethane, which is not only wear-resistant, but also the screen holes can be flexibly customized according to the demand, which is suitable for the dewatering of fine sand with different particle sizes.
4. Intelligent adjustment system: adjustable fineness modulus, pump speed, flow rate, concentration and other parameters can be adjusted according to the demand of the production line, which can be flexibly adapted to a variety of operating scenarios.
5. low noise, low energy consumption operation: the use of rubber shock absorbing base, equipment running low vibration, low noise, stable work, suitable for projects with high environmental requirements.

Advantages of double wheel sand washing and fine sand recovery integrated machine:

1. fine washing, secondary purification: double-wheel washing design, compared with the traditional single-wheel sand washing machine, can further reduce the mud powder content in the finished sand by 20%~50%, effectively improving the cleanliness of sand.
2. Effective recovery of fine sand, high resource utilization: the tailing sand enters the dewatering screen after concentration by high-pressure cyclone separator, which effectively recovers the fine particle sand and reduces the waste of raw materials.
3. Excellent dewatering effect: the water content of the material recovered by the dewatering screen is low, the efficiency of the sand is high, and the water content of the finished sand is controlled below 15%, which is convenient for direct transportation and use.
4. compact structure, reliable operation: the whole machine structure is reasonable, the key parts are made of high-strength materials, prolonging the service life of the equipment, easy maintenance and easy replacement.
5. customized service, strong adaptability: non-standard customization can be made according to the user’s output, material characteristics, water content and other parameters to meet the needs of different working conditions of washing and recycling.

The working principle of double wheel sand washing and fine sand recovery integrated machine:

When the equipment is running, the pump transports the sand-water slurry mixed with fine sand to the high-pressure cyclone, which centrifugally classifies the mixed slurry, so that the coarse and fine particles can realize preliminary separation. The separated fine sand is deposited and enters the dewatering screen through the sand sinking nozzle to complete the water-sand separation and dewatering operation.

The small amount of sediment and water that is not recovered enters the front cleaning area through the return tank to realize re-cleaning and re-cycling. At the same time, the water level in the cleaning tank is equipped with an automatically adjustable overflow port, which can export the excess water and keep the system running stably.

The fineness modulus and the composition of the finished sand particles can be flexibly controlled by adjusting the pump speed, slurry concentration, cyclone feed pressure, etc., realizing the fine management of the cleaning, grading and dewatering process.

Application areas of double wheel sand washing and fine sand recovery integrated machine:

1. Mechanized sand plant: It is widely used for cleaning and recovering fine sand in the production line of mechanized sand to improve the quality of finished sand and gravel products.
2. Sand and gravel aggregate plant: wash away the mud powder in natural or mechanism sand, improve the cleanliness of sand and enhance the performance of concrete.
3. Hydroelectric power station project: supporting sand and gravel system for cleaning and grading of sand and gravel materials after river dredging.
4. Environmental sand plant/sand processing station: for the recycling and reuse of construction mud, tailing sand and other waste resources.
5. Dry mortar enterprises: used in the pre-treatment process of dust and mud removal for raw sand.
