Kraft Liner Pulping Line: Quality Control and Performance Metrics

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 enabling production flexibility to switch between paper grades in under 2 hours.

Energy Efficiency and Cost Optimization

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: Flotation Deinking Cell

Capacity 50-120 TPD per cell, ink removal 85-92%, brightness gain 10-15 points ISO, air-to-stock ratio 0.3-0.5.

When paired with the primary equipment, the Flotation Deinking Cell delivers achieves iso brightness above 90% for cultural paper, enabling 100% recycled fiber processing without compromising paper strength.
