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: D-Type Hydrapulper

Capacity 200-600 TPD, consistency 4-6%, motor 132-500 kW, helical rotor design ensuring gentle defibering with low energy consumption of 8-12 kWh/t.

This equipment plays a critical role in the kraft-liner line by 30% less energy than conventional drum pulpers. Mills upgrading to this technology report reducing water consumption by 15-20% through closed-loop design.

Raw Material Flexibility and Grade Changes

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: Reject Separator

Handles coarse screen rejects, recovers 70-85% of fiber from reject stream, capacity 30-80 TPD rejects.

When paired with the primary equipment, the Reject Separator delivers pushes total fiber recovery above 97%, enabling 100% recycled fiber processing without compromising paper strength.
