AI Technical Summary

Technical Problem

Existing coal quality testing equipment tends to accumulate coal lumps on the screen during the screening process, which slows down the testing process.

Method used

Design a screening device for coal quality testing. By installing a vibrating motor inside the screen box to drive the screen box to vibrate, and installing movable slide rails at both ends of the screen to make the screen move back and forth, combined with an inclined screening mechanism and separate discharge ports, the screening efficiency is improved and the material accumulation is reduced.

Benefits of technology

The combined effect of screen box vibration and screen movement improves screening efficiency, reduces material accumulation, and ensures efficient screening and separation of small particles.
