Kingwood: Industrial Wood Pellet Press Machine Manufacturer Since 1999
Jiangsu Kingwood Industrial Co., Ltd. (NEEQ stock code: 871765) is a China-based wholesale wood pellet press machine manufacturer headquartered at #568 Hongsheng Road, Liyang Zhongguancun Industrial Park, Jiangsu Province. Founded in 1999, the company brings 27 years of focused R&D and a 20-strong engineering team to the design, manufacture, and commissioning of ring die pellet mills and complete biomass pellet production lines for industrial buyers across 30+ countries.
Kingwood operates from a 31,200 m² facility — 25,000 m² of production floor and 6,200 m² of technical and administrative space — supporting the full manufacturing cycle from component fabrication through line integration and factory acceptance testing.
Certifications include ISO 9001, ISO 14001, and CE. Institutional recognitions cover Jiangsu Provincial High-Tech Enterprise, Jiangsu Provincial Gazelle Enterprise, Jiangsu Provincial Specialized & Innovative Niche Leader, and Deputy Director Member Unit of the China Biomass Energy Industry Alliance.

Pellet Mill Models and Complete Line Specifications
Kingwood’s pellet mill range addresses throughput requirements from entry-level industrial installations to high-volume commercial fuel production.
Vertical Ring Die Pellet Mills
- JWZL-420 — 1.0–1.5 t/h
- JWZL-688 — 2.0–2.3 t/h
- JWZL-688D — 3.0–3.5 t/h
- JWZL-928 — 4.0–5.0 t/h
- JWZL-1068 — contact sales for capacity specification
Horizontal Ring Die Pellet Mill
- JZWH-860 — 4.0–5.0 t/h
For buyers sourcing turnkey plant solutions, Kingwood engineers wet-feed biomass pellet production lines scaled up to 200,000 metric tons per year. These lines process high-moisture raw materials — wood chips, agricultural residues, forestry waste — through an integrated sequence: drum chipping, coarse hammer milling, drum drying, fine grinding, ring die pelletizing, counter-flow cooling, and automated packaging. All material handling is fully enclosed with integrated dust removal throughout.
Auxiliary equipment manufactured in-house includes hammer mills, drum chippers, drum dryers, counter-flow coolers, and pellet packaging machines — enabling single-source procurement across the complete production line. See the full auxiliary equipment range for specifications.
Three-Standardization Framework: Kingwood’s Engineering Standard
Kingwood applies its proprietary Three-Standardization Framework across all production line designs and project engineering engagements:
- Integrated production lines — process stages are designed as a unified system with matched throughput at each stage, eliminating bottlenecks that arise when unrelated equipment is assembled into a line.
- Dust-Free production lines — fully enclosed material handling combined with integrated dust extraction eliminates fugitive emissions, meeting occupational safety requirements and environmental permit conditions. A 2024 installation in Guizhou, China demonstrates this standard at commercial scale.
- Automated production lines — PLC-driven controls, automated material feeding, and remote monitoring capability reduce operator headcount requirements and improve process repeatability across shifts.
This framework is the basis for Kingwood’s position as a standardized biomass pellet plant supplier rather than a provider of one-off custom builds — a distinction that matters for buyers managing multi-site rollouts or replicating proven production models.
Verified Project References
Kingwood’s export and domestic installation history provides verifiable performance benchmarks for procurement teams conducting technical due diligence:
- Vietnam, 2023 — 24 t/h wood chip pellet production line: large-scale export installation using Kingwood ring die mills and complete line equipment.
- Vietnam, 2024 — 12 t/h wood pellet line with 23-month payback: full investment recovery achieved in 23 months under commercial operating conditions.
- Chongqing, China, 2021 — 30 t/h domestic wood pellet mill: high-throughput installation for an industrial biomass fuel producer.
- Beijing, China, 2024 — Beijing’s first biomass pellet demonstration project: urban biomass fuel flagship, establishing a replicable model for municipal biomass adoption.
Across more than 2,000 planned and designed production line projects since 1999, Kingwood equipment supports an aggregate annual biomass fuel output capacity of 10 million metric tons.
Fuel Output Quality and Cost Economics
Biomass pellets produced on Kingwood equipment meet the following verified specifications, benchmarked against major international standards:
| Parameter | Kingwood Output | Reference Standard |
|---|---|---|
| Calorific value | ≥ 4,800 kcal/kg | USA: > 2,500 kcal/kg |
| Moisture content | < 15% | EU: < 15% |
| Sulfur content | < 0.3% | Japan: ≤ 0.5% |
| Ash content | < 18% | ISO: < 20% |
| Dioxin emissions | < 0.5 ng TEQ | China GB: ≤ 1.0 ng TEQ |
All emission indicators comply with GB13271-2001, China’s national Emission Standard of Air Pollutants for Boilers. Under documented operating conditions, substituting biomass pellets for fossil fuel alternatives reduces fuel costs by 40–50%.
