The drum screen is a multifunctional auxiliary device used for **raw material pretreatment and finished product grading** in wood chip charcoal production lines. During the raw material preparation stage, its primary function is to screen crushed wood chips through a rotating drum, removing oversized particles and impurities to ensure uniform particle size of the material entering the dryer.

Featuring a rotating drum structure, this equipment enables flexible grading by adjusting screen mesh apertures. It operates smoothly with high screening efficiency and minimal clogging. As a pivotal link in the production chain, the drum screen ensures consistent raw material quality for both drying and briquetting processes while enhancing the final charcoal product’s quality and market competitiveness.
