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: Disc Thickener

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

This equipment plays a critical role in the kraft-liner line by energy-efficient dewatering with minimal fiber loss. Mills upgrading to this technology report reducing annual operating costs by $50,000-120,000 on a 400 TPD line.

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: Fractionation Screen

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

When paired with the primary equipment, the Fractionation Screen delivers optimizes fiber utilization by grade, achieving consistent product quality with less than 2% variation.
