Which is Better, the Fine Sand Recovery Equipment

For many users (such as Sri Lanka, Nepal), losing fine sand during sand washing is a major problem. Usually, depending on the actual situation of the user production line, we will recommend a slight sand recovery machine or sand washing recovery machine to solve this problem. They are typically used in the cleaning and recycling of artificial sand, and they all have the function of superb sand recycling. However, there are still some differences in the functions of the two. This paper is a simple analysis for you, in the sand production line, to solve the problem of adequate sand loss, fine sand recovery machine, and sand washing recovery machine in which case?

To analyze which situation the two apply to, first, we must get a basic understanding of the composition and processing principles of the two machines.

Fine Sand Recycle

Structure: The fine sand recovery machine is mainly composed of a motor, a vacuum high-pressure pump, a sediment separator, a vibrating dewatering screen, a cleaning tank, a return box, and so on. It mainly recovers the fine sand in the sand washing waste-water generated during the operation of the sand washing machine dehydration operation.

Working Principle: When the fine sand recovery machine is working, the sand washing waste-water is transported to the cleaning tank of the equipment, and then the sand-water mixture in the cleaning tank is transported to the cyclone through the slurry pump, and the concentrated fine sand is passed through the cyclone centrifuge. The vibrating dewatering screen is supplied through the discharge box and dehydrated by the vibrating dewatering screen, and the fine sand is output from the front of the screen. A small amount of fine sand, mud, etc. will be returned to the cleaning tank through the return box, cyclically, to achieve the purpose of recycling, dewatering, and full discharge of the fine sand in the sand washing waste-water.

Sand Washing Recovery Machine

Structure: Sand washing and recycling integrated machine is mainly composed of a high-pressure separator, dewatering screen, impeller separator, reducer, vacuum high-pressure pump, cleaning box, high-position return tank, motor, vibration motor, and other components. It has water-washed sand, concentrated dewatering of coarse and fine sand. And fine sand. Recycling and other functions.

Working Principle: When and washing and recycling integrated machine is working. It was cleaned by the impeller separator and the sand and mud are separated. The sand and gravel materials enter the lower dewatering screen for dewatering treatment, and the waste-water overflowing from the cleaning tank (containing a large amount of fine sand, mud, dust, and other impurities) transported to the high-pressure separator by the vacuum high-pressure pump, the fine sand concentrated by centrifugation is discharged into the upper layer of the dewatering screen through the sand settling nozzle for dehydration treatment, and the remaining waste-water, mud, dust, and other impurities are passed through the high-pressure separator The overflow port is discharged into the high-level return water tank.

Conclusion: Through the above introduction, it can be pointed out that the function of the fine sand recovery machine is mainly the extraction and recovery of the lost fine sand. In the sand production line, the fine sand recovery machine is mainly used after the sand washing machine (used with the sand washing machine), and the washing The sand recovery integrated machine adds the function of sand washing based on the fine sand recovery machine. When using this equipment, there is no requirement to configure a sand washing machine, and it can be configured as a dual-wheel or according to the mud content of the material and cleaning requirements. Single-wheel and washing machine.

According to relevant statistics, most of the sand production lines that use the wet separation process have the problem of superb sand loss, which can even reach more than 20% when the loss is profound. Therefore, most users will configure fine sand recovery devices to recover outstanding sand and improve economic benefits. At the same time, it also reduces the costs of tailings and the pollution and damage to the environment caused by the loss of fine sand, which has played a twofold role in increasing efficiency, energy conservation, and environmental protection.
