AI Technical Summary
Traditional rotary screen sand and gravel separators have small screen apertures that are prone to clogging, requiring regular manual cleaning. Furthermore, the screen replacement process is complex and maintenance costs are high.
A sand and gravel separator was designed, comprising a frame, a screening base, a screen, and a vibrating motor. The screen is detachably connected by bolts and equipped with a fixing mechanism, which facilitates quick disassembly and replacement, reducing the disassembly steps of the core parts of the equipment.
It enables quick disassembly and replacement of the screen, reduces maintenance costs, and improves the convenience and efficiency of equipment maintenance.
