The fine sand recovery device can be used in the dehydration process of ceramic raw material processing systems, tailings recovery and treatment in mineral processing plants, quartz sand processing systems, hydropower station sand and gravel processing systems, etc., which can effectively solve the problem of fine sand and fine material recovery. For example, in the dehydration process of some ceramic raw materials, a vacuum filter is used, which requires high investment and power consumption, and requires frequent replacement of filter cloth, making it particularly inconvenient to use. A fine sand recovery device can be used instead of the filter to dehydrate the materials, meeting the requirements of dry stacking and transportation. In addition, the fine sand recovery device has low investment, low power consumption, and easy operation and use.
