Description

Technical Field

[0001] The utility model mainly relates to the technical field of sand screening, in particular to a sand screening device for construction. Background Art

[0002] In the process of screening and sorting sand, we need to use a screening machine to accurately screen according to different requirements for sand quality. During the screening process, when the sand passes through the screen, due to the difference in its particle size, the fine sand can pass through the bottom of the screen smoothly, while the coarse sand will be intercepted by the screen.

[0003] Normally, in order to recycle the coarse sand, we need to remove the screen from the screening machine and then carry out subsequent recycling work. This process is not only cumbersome to operate, but may also lead to a decrease in screening efficiency and even affect the service life of the screen. Utility Model Content
