Before delving into Leizhan’s innovation, it’s essential to understand the Drum Screen’s function. Positioned early in the stock preparation line—often after pulping and before fine cleaning—the drum screen’s primary task is to remove oversized, abrasive, or non-fibrous contaminants from the pulp slurry. By removing these impurities, the Drum Screen prevents downstream blockages, reduces wear on pumps and cleaners, and significantly improves the final sheet quality.

Built with heavy-duty stainless steel and fortified at critical wear points, the Leizhan Drum Screen withstands the abrasive nature of recycled pulp. The screen cylinder features precisely perforated or slotted plates, available in various hole/slot sizes to match specific separation needs—whether for coarse removal or fine screening applications. Leizhan Drum Screens can be tailored to specific mill requirements—whether for OCC (Old Corrugated Containers), ONP (Old Newspapers), mixed waste, or virgin pulp systems. The Drum Screen can be installed in a gravity-fed or pressure-fed setup, offering flexibility in plant layout and process integration.

For mills aiming to boost productivity, improve product consistency, and reduce operational costs, the Leizhan Drum Screen stands as a proven, high-performance guardian at the gateway to the papermaking process.
