AI Technical Summary
In the screening process of manufactured sand, existing construction waste screening devices are prone to sand accumulation, which can cause screen hole blockage, affecting screening quality and reducing screening efficiency.
The system employs a quantitative screening assembly, including an upper screening plate and a lower screening plate, combined with a vibrating motor and a rotating roller. It quantitatively feeds and classifies and collects manufactured sand, avoiding screen clogging and improving screening efficiency. A silicone flexible plate is used to prevent jamming.
It achieves efficient classification and collection of manufactured sand, avoids screen clogging, improves screening quality and efficiency, and extends the service life of the equipment.
