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

System Integration and Line Balancing

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: Disc Thickener

Inlet consistency 0.8-1.2%, discharge 8-12%, disc diameter 2500-3500 mm, water removal 3-5 tons/hour.

When paired with the primary equipment, the Disc Thickener delivers energy-efficient dewatering with minimal fiber loss, extending equipment service life by 2-3 years with proper maintenance.
