Kingwood: Industrial-Grade Wood Pellet Press Machines from China
Jiangsu Kingwood Industrial Co., Ltd. — operating under the brand name Kingwood — is a China-based wholesale wood pellet press machine factory with 27 years of dedicated R&D in biomass pellet equipment. Founded in 1999 and headquartered at #568 Hongsheng Road, Liyang City, Jiangsu Province, Kingwood designs, manufactures, and commissions ring die pellet mills and complete biomass pellet production lines for industrial buyers across 30+ countries.
Kingwood is listed on the NEEQ (National Equities Exchange and Quotations) under stock code 871765, operates a 25,000 m² production facility alongside 6,200 m² of engineering and office space, and employs a 20-strong R&D team. The company’s track record spans more than 2,000 planned and designed production line projects — a body of applied engineering experience that directly informs every machine that leaves the Liyang factory.

Wood Pellet Press Machine Models and Specifications
Kingwood’s core product range centres on the ring die — both vertical and horizontal configurations — to match the mechanical demands of high-throughput biomass pelletizing.
Vertical ring die pellet mills:
| Model | Rated 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 | Rated Capacity |
|---|---|
| JZWH-860 | 4–5 t/h |
For buyers requiring a full processing solution, Kingwood supplies complete wet-feed biomass pellet production lines rated up to 200,000 metric tons per year. Each line integrates a hammer mill for fine grinding, a drum chipper for raw material size reduction, a drum dryer for moisture control, the pellet mill itself, a counter-flow cooler for post-pelletizing temperature management, and automated packaging. The entire process runs in an enclosed, dust-controlled environment — a direct application of Kingwood’s Dust-Free production line pillar.

Three-Standardization Framework: The Engineering Standard Behind Every Line
Kingwood differentiates its offering through the proprietary Three-Standardization Framework, which governs how every production line is engineered, commissioned, and handed over:
- Integrated production lines — all process stages (size reduction through packaging) are designed as a single mechanical and control system, eliminating inter-stage compatibility issues.
- Dust-Free production lines — enclosed conveyance, integrated dust extraction, and sealed transitions reduce airborne particulate at source, supporting operator safety and regulatory compliance.
- Automated production lines — PLC-based control, sensor-driven process monitoring, and remote diagnostics reduce manual intervention and support consistent pellet quality across shifts.
This framework is not a marketing label. It is an engineering checklist applied across all 2,000+ projects Kingwood has planned and designed. The 2024 Guizhou Dust-Free biomass pellet workshop is one documented example of the framework applied at greenfield scale.
Verified Project Performance and Fuel Quality
Kingwood’s equipment is validated through documented field deployments. Key reference projects include:
- Vietnam, 2023 — 24 t/h wood chip to pellet production line (full case study)
- Vietnam, 2024 — 12 t/h wood pellet line with a verified 23-month investment payback period (case study)
- Chongqing, China, 2021 — 30 t/h wood pellet mill (case study)
- Beijing, China, 2024 — Beijing’s first biomass pellet demonstration project
The biomass fuel produced on Kingwood lines meets the following verified specifications:
- Calorific value: 4,800 kcal/kg
- Moisture content: < 15% (meets EU standard)
- Sulfur content: < 0.3% (within Japan’s ≤ 0.5% threshold)
- Ash content: < 18% (within ISO < 20% ceiling)
- Dioxin content: < 0.5 ng-TEQ (below China GB ≤ 1.0 ng-TEQ limit)
- All combustion emissions comply with GB13271-2001
At current energy prices, operators switching from fossil fuels to Kingwood-produced biomass pellets report fuel cost reductions of 40–50%.
