In the sand production line, the content of impurities and mud mixed in sand is relatively high. In order to produce the high quality of sand, sand washing machine is usually used to wash sand and remove the impurities and mud in sand. However, no matter what type of sand washing machine used, it is inevitably lead to the loss of fine sand, which will affect the gradation of coarse and fine grain size of sand and greatly reduce the sand quality. And excessive fine sand discharge will also cause environmental pollution.
The traditional sand production line generally uses a sedimentation tank to recover fine sand after sand washing machines. However, the construction of sedimentation tank requires a large area, and the muddy water from sand washing equipment is easily fouled in sedimentation tank. And cleaning the sedimentation tank once is labor intensive and expensive. But the amount of fine sand recovered is very low.
In order to solve this situation, LZZG absorbed foreign technology and combined with the actual situation, designed dewatering screen with cyclone equipment, which is also known as fine sand recycling machine, fine sand recovery system, and fine sand recovery equipment. The dewatering screen with cyclone system is widely used in sand and gravel production plant, glass raw material processing system, coal mining plant, slurry recovery and environmental protection engineering, which can effectively solve the problem of fine sand loss. The machine can effectively recycle more than 95% of fine sand in muddy water after sand washing machine and reduce the loss of fine sand. Thereby greatly improve the quality of final sand and increase the production of sand production line. The fine sand recycling machine has a small footprint, saves water resources, and has high efficiency in electric production.
A sand production line with sand washing machines is also indispensable for sand recycling machines. The cost of adding a fine sand recovery machine is about thousands of dollars, but the amount of fine sand recovered every day is thousands of tons, and the fine sand price in current market is indeed high, so the benefits of using a fine sand recycling machine are considerable. So sand washing equipment and fine sand recycling machine are also known as the golden partner in sand production line.
