Fujian Biomass Pellet Line: 12-16 t/h JWZL-1068 Forestry Waste Project

Project Summary

A complete biomass pellet production line centered on Kingwood’s JWZL-1068 vertical biomass pellet mill was assembled and shipped to Fujian Province in 2024. The facility is designed to process 100,000 metric tons of local forestry waste annually, converting sawdust, wood chips, and logging residues into standardized biomass fuel pellets at a rated capacity of 12 to 16 tons per hour.

Fujian’s timber processing sector generates substantial volumes of forestry residues that historically went underutilized. This installation addresses both waste management and renewable energy supply by establishing a closed-loop system where mill waste becomes feedstock for pellet production. The operator selected Kingwood based on the company’s 27 years of R&D experience and proven track record across 2,000 production line projects globally.

The line represents a typical wet-feed pellet production configuration: crushing, coarse grinding, drying, fine grinding, pelletizing, cooling, and packaging stages integrated with dust removal systems. For procurement teams evaluating similar projects, this case demonstrates the scale and equipment selection appropriate for regional forestry waste volumes in the 80,000-120,000 ton/year range.

Equipment and Capacity

The JWZL-1068 serves as the core pelletizing unit. This vertical ring die pellet mill features multi-station die configuration, allowing continuous pellet extrusion while individual die sections undergo maintenance or replacement. The transcript indicates stable, high-quality pellet production through what Kingwood terms “multi-station synergy”—likely referring to the ability to maintain output even during partial die servicing.

Supporting equipment includes a hammer mill for initial size reduction, drum dryer to reduce moisture content from field levels (typically 40-50% for fresh forestry waste) down to the 10-15% range required for pelletization, and a counter-flow cooler to bring finished pellets from extrusion temperature (~80-90°C) down to ambient plus 5-8°C for safe storage. The complete line operates as an enclosed system with integrated dust collection, meeting China’s industrial emission standards for biomass processing facilities.

Rated throughput of 12-16 t/h allows the facility to process its annual 100,000-ton feedstock target with approximately 6,500-8,000 operating hours per year, accounting for maintenance downtime and seasonal feedstock availability variations. This operating schedule aligns with typical industrial pellet plant utilization rates in China’s southeastern provinces.

For context on equipment selection, Kingwood’s JWZL-928 vertical biomass pellet mill offers 4-5 t/h capacity and serves as the mid-range option for operators processing 30,000-50,000 tons annually. The JWZL-1068 represents the next capacity tier for regional-scale operations.

Watch the Project

The following footage shows the complete line during final assembly and pre-shipment inspection at Kingwood’s Liyang facility:

The video confirms the line’s modular construction, with individual processing stages pre-assembled on structural frames for efficient installation at the Fujian site. This approach reduces on-site commissioning time from 8-12 weeks (typical for field-assembled systems) to 4-6 weeks for pre-integrated modules.

Procurement teams should note the enclosed conveyor systems visible in the footage—these prevent material loss during transfer between processing stages and maintain consistent moisture content by limiting atmospheric exposure. The integrated dust collection hoods on the hammer mill and pellet mill sections indicate compliance with GB 16297-1996 emission standards for particulate matter in industrial facilities.
