Leizhan 300,000T Kraft Board Paper Making Line
Recycled fiber is no longer a compromise — it is a competitive advantage when the pulping system is built right. Leizhan’s 300,000-tonne-per-year kraft board line starts with that premise. Whether your furnish is 100% OCC, a mix with virgin pulp, or a blend tailored to local fiber availability, the stock preparation section removes contaminants, preserves fiber length, and delivers clean, consistent pulp to the wire.
The key is in the details most buyers overlook. Our high-consistency pulpers operate at the optimal consistency window for OCC defibering without excessive cutting. Downstream, a cascade of high-efficiency cleaners and fine screens catches stickies, plastics, and sand before they reach the headbox. The result is a sheet with the tensile and burst values your customers spec, even when the raw material coming in the gate is far from perfect.
Specification of 300,000T Kraft Board Paper Making Line
Raw material: wood pulp, OCC
Paper type: High-grade kraft paper
Base weight: 100-200GSM
Trimmed width: 5660mm
Production capacity: 1200tpd
Annual production capacity: 300000t
On the paper machine itself, the 5660 mm width and 100–200 GSM range give you room to move. Run heavier grades for export containerboard when the price is right, then shift to lighter testliner for domestic corrugated markets without a major grade change. The press section is configured for efficient water removal at both ends of the weight spectrum, and the dryer section recovers enough exhaust heat to measurably cut your steam bill.
Installation and startup follow the same tailored approach. Our project managers coordinate shipping, customs clearance, and site logistics based on experience from mills in similar regions. Commissioning includes running your actual furnish through the line, tuning the process parameters, and training your operators on real production data — not textbook examples. After handover, our service team remains on call for remote troubleshooting, annual inspections, and process optimization visits.
If your mill is sitting on a growing supply of OCC and looking for the most profitable way to convert it into saleable board, this line deserves a place in your evaluation. Email address:paperproductmachine@gmail.com
