Kraft Liner Pulping Line: Maintenance Best Practices and Service Intervals

The kraft liner pulping production line requires carefully integrated equipment to achieve optimal performance. Modern systems from Zhengzhou Leizhan Technology incorporate advanced process control, energy-efficient components, and robust construction for reliable 24/7 operation.

Core Equipment: Fractionation Screen

Separates long fiber (>1.2mm) from short fiber, capacity 100-300 TPD, slot/hole combination baskets.

This equipment plays a critical role in the kraft-liner line by optimizes fiber utilization by grade. Mills upgrading to this technology report enabling 100% recycled fiber processing without compromising paper strength.

Capacity Planning and Production Scaling

Beyond individual equipment performance, the integration between processing stages determines overall line efficiency. The kraft liner pulping system is designed as a complete solution where each stage is sized for balanced throughput.

Supplementary Equipment: Pressure Screen MZS Series

Slot sizes 0.15-0.50 mm, capacity 80-800 TPD, fiber recovery above 95%, feed consistency 0.8-1.5%.

When paired with the primary equipment, the Pressure Screen MZS Series delivers precision contaminant removal while preserving fiber length, reducing annual operating costs by $50,000-120,000 on a 400 TPD line.
