The current artificial sand production line equipment, for sands containing large amounts of mud or for mixtures of sand containing large amounts of sand, will not meet the requirements of the final product sands alone, regardless of the type of sand washing machine chosen, which is expressed as having a large amount of mud and a serious defect of fine sand loss. What's the effect of dehydration and sand recovery
I. Description of dehydration
The main function of dehydration screening is dehydration, de-slubling, de-salubling, often used in conjunction with wet rule-of-law sand production lines and sand washing machines, and may also be used alone. Sandstones are washed through sand washing machines to achieve a reasonable ratio of grain sizes through sand-de-scrutinization, de-slubling, recovery of fine sands, reducing the amount of mud to less than 0. 7 per cent。
Advantages of dehydration screening equipment:
1. The dehydrated sift is advanced, small in size, light in weight, works efficiently and with low noise and selects a new type of vibrating machine for direct driving。
2. Dehydration sift beams are connected to the sift selection with a high-strength bolt, without welding。
3. Polyurethane (pur) screening network with high screening rate, high production volume and long service life。
Dehydration screening has a range of advantages, such as high production volumes, sound performance parameters, high structural intensity, serialization, interoperability, high standardization levels and ease of maintenance and repair。
Ii. Introduction to the sand recycler
Fine sand recovery machines are commonly used as sand recovery devices, which need to be used in conjunction with sand washing machines, to recover large amounts of sands lost by sand washing machines in traditional sand-making industries (more than 20 per cent in cases of severe loss), and to increase economic efficiency while reducing the cost of handling tailings and the environmental pollution and damage caused by the loss of sand。
A sand recovery machine is more powerful than a dehydration sift and not only cleans up, but also recovers fine sand. A sand recovery machine can separate sand from sand in a sand water mixture and extract and collect fine sand, improving the quality and yield of sand by washing, dehydrating, grading and significantly reducing the sediment content of sand with a recovery rate of over 85 per cent。
Advantages of sand recovery machine equipment:
1. Fine sand recovery is more than 85 per cent efficient。
2. Long-lasting grinding, durability and excessive useful life。
3. Economic and environmental protection to reduce pollution and generate revenue。
4. The wide range of applications, industries and practicalities。
Iii. Sewer dehydration collectors — sand recovery dehydration aircraft
The fine sand recovery dehydrator is divided into two systems: dehydration, which consists of dehydration sifting and vibration engines, and recovery, which consists of vacuum high-pressure pumps, electric generators, high-pressure separators, water-returners, and washing boxes。
It is usually possible to assemble directly in the tail of the washing machine equipment, to re-clean the sand after washing the washing machine equipment, or to separate the waste water from the washing machine equipment, which adequately addresses the shortcomings of the washing machine equipment (e. G., the high water content of the finished sand, the high amount of mud, the high dust content, the difficulty of removing the impurities, etc.) and further improves the grade of the finished sand。
