Kraft Liner Pulping Line: Process Flow and Key Operating Parameters

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: Low Density Cleaner System

Operating consistency 0.6-1.2%, pressure drop 1.2-1.8 bar, lightweight contaminant removal above 90%.

This equipment plays a critical role in the kraft-liner line by superior stickies and plastic removal. Mills upgrading to this technology report lowering spare parts costs by 25% through standardized components.

Maintenance Best Practices and Service Intervals

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: 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.

When paired with the primary equipment, the D-Type Hydrapulper delivers 30% less energy than conventional drum pulpers, enabling production flexibility to switch between paper grades in under 2 hours.
