[0002] In many rapidly developing industrial fields, sand, as an indispensable basic raw material, has always played an important role. However, the moisture content of wet sand has always been a key factor restricting its application effect. Sand with too high a moisture content not only affects its performance, but is also directly related to a series of production quality and cost issues. Therefore, how to effectively reduce the moisture content of wet sand and improve processing efficiency has always been an important research direction in the field of industrial application technology.

[0003] Traditional methods for reducing the moisture content of wet sand mainly include centrifugal dehydration, sun drying and heating and drying. Although these methods can reduce the moisture content of wet sand to a certain extent, they have inherent disadvantages and limitations in terms of cost and efficiency.
