Ring Die Pellet Mill Product Range

Kingwood’s core product line centers on the ring die pellet mill — the preferred configuration for industrial-scale wood pellet production due to its higher throughput, die longevity, and consistent pellet density versus flat die alternatives.

Vertical ring die pellet mills:

Model	Capacity
JWZL-420	1–1.5 t/h
JWZL-688	2–2.3 t/h
JWZL-688D	3–3.5 t/h
JWZL-928	4–5 t/h
JWZL-1068	Contact sales

Horizontal ring die pellet mill:

Model	Capacity
JZWH-860	4–5 t/h

Each model is engineered for biomass feedstocks including wood chips, sawdust, agricultural straw, rice husk, and mixed woody residues. Buyers sourcing a China wholesale wood pellet press making machine for mid- to large-scale operations can configure any model into a complete automated line.

Auxiliary equipment available from Kingwood includes hammer mills, drum chippers, drum dryers, counter-flow coolers, and pellet packaging machines — all designed for integration into a single enclosed production system.

Complete Wet-Feed Biomass Pellet Production Lines

Beyond individual machines, Kingwood’s primary commercial offering is the complete wet-feed pellet production line — designed to handle high-moisture raw biomass without pre-drying, reducing energy input at the front end of the process.

A standard Kingwood complete line covers:

1. Coarse size reduction — drum chipper or hammer mill stage
2. Drying — rotary drum dryer reducing feedstock moisture to process-ready levels
3. Fine grinding — secondary hammer mill to target particle size
4. Pelletizing — ring die pellet mill (vertical or horizontal configuration)
5. Cooling — counter-flow cooler bringing pellet temperature and moisture within storage and shipping specifications
6. Packaging — automated pellet packaging integrated into the line

Maximum designed line output: 200,000 metric tons per year. All lines are built to Kingwood’s proprietary Three-Standardization Framework, meaning every installation is Integrated, Dust-Free, and fully Automated — reducing manual labor requirements, eliminating fugitive dust hazards, and enabling remote process monitoring.

Documented installations include a 24 t/h wood chip pellet production line in Vietnam (2023), a 12 t/h line in Vietnam with a 23-month payback period (2024), a 30 t/h line in Chongqing, China (2021), and Beijing’s first biomass pellet demonstration project (2024).

Biomass Pellet Fuel Quality and Compliance

Pellets produced on Kingwood lines consistently meet the following specifications:

• Calorific value: ≥ 4,800 kcal/kg
• Moisture content: < 15% (EU standard compliant)
• Sulfur content: < 0.3% (below Japan’s ≤ 0.5% threshold)
• Ash content: < 18% (below ISO’s < 20% ceiling)
• Dioxin emissions: < 0.5 ng TEQ (well within China GB ≤ 1.0 ng TEQ)

All combustion emissions from Kingwood-line-produced biomass fuel fall below GB13271-2001, China’s national Emission Standard of Air Pollutants for Boilers. Industrial buyers switching from coal or heavy fuel oil to biomass pellets produced on Kingwood lines report 40–50% reductions in fuel costs.
