Chain Conveyor for Recycled Stock Preparation

In a modern pulp mill, the conveyor that feeds the pulper is not just a transport device — it is the gatekeeper of the entire stock preparation process. An unreliable conveyor causes bottlenecks, uneven pulper loading, and unnecessary downtime. Leizhan’s drag chain conveyor was developed with this reality in mind, drawing on decades of field experience from mills running 24/7 operations.

One of the key strengths of this conveyor is its adaptability. It handles everything from loose post-consumer cardboard to tightly wired bales with equal confidence. The V-profile feeding plate and wide effective conveying surface ensure that material enters the pulper at a controlled, steady rate, which helps maintain consistent pulp quality and protects downstream screening and cleaning equipment from overload.

Features of Chain Conveyor for Recycled Stock Preparation

1. Trough plates are produced by precision punch forming, resulting in high structural strength and effective crushing or loosening of compacted waste paper as it moves.
2. Closed-design chain boards prevent material leakage, keeping the mill floor clean and reducing housekeeping labor.
3. Dual-row idler traction chains with hollow roller shafts allow centralized lubrication; oil is fed through the pin roll to lubricate both the shaft sleeve and the durable zinc-copper bushing inside.
4. A long-axis connection between the two chain rows effectively counters chain running deviation, even when loads are unevenly distributed.

From single machines to complete pulping lines, Leizhan supports paper mills worldwide with engineering, manufacturing, and project management under one roof. We also offer full EPC services for greenfield and expansion projects, covering layout design, civil coordination, equipment supply, installation supervision, commissioning, and training.
