Kingwood: Industrial Wood Pellet Press Machine Manufacturer Since 1999
Jiangsu Kingwood Industrial Co., Ltd. — operating under the brand name Kingwood, NEEQ-listed at stock code 871765 — is a dedicated biomass pellet equipment manufacturer headquartered at #568 Hongsheng Road, Liyang City, Jiangsu Province, China. Founded in 1999, the company has accumulated 27 years of focused R&D in biomass pellet machinery and renewable energy equipment.
Kingwood’s engineering and production infrastructure covers 31,200 m² in total, including 25,000 m² of production floor space and 6,200 m² of office and R&D facilities, located within the Liyang Zhongguancun Industrial Park. A team of 20 dedicated R&D experts supports continuous product development across pellet mill design, process engineering, and automation integration.
The company is ISO 9001 and ISO 14001 certified, CE-marked, and holds multiple provincial designations: Jiangsu Provincial High-Tech Enterprise, Jiangsu Provincial Specialized & Innovative Niche Leader, and Jiangsu Provincial Gazelle Enterprise. Kingwood is also a Deputy Director Member Unit of the China Biomass Energy Industry Alliance.
Wood Pellet Press Machine Models and Production Line Configurations
Kingwood’s core product range centers on ring die biomass pellet mills in both vertical and horizontal configurations, supported by a full suite of auxiliary equipment for complete-line installations.
Vertical biomass 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 biomass pellet mill:
| Model | Capacity |
|---|---|
| JZWH-860 | 4–5 t/h |
Beyond standalone pellet mills, Kingwood engineers complete wet-feed biomass pellet production lines designed for high-moisture raw materials. These lines integrate every process stage: crushing, coarse grinding, drum drying, fine grinding via hammer mill, pelletizing, counter-flow cooling, and automated packaging. All lines are fully enclosed with integrated dust removal systems. Single-line engineered capacity reaches up to 200,000 metric tons per year.
Auxiliary equipment supplied includes drum chippers, hammer mills, drum dryers, counter-flow coolers, and pellet packaging machines — enabling turnkey project delivery under one manufacturer.
For detailed specifications on the JWZL-928 and JWZL-688D models, see the Kingwood vertical pellet mill product pages.
Three-Standardization Framework: Engineering Standard for Industrial Lines
Every Kingwood production line is designed and delivered under the company’s proprietary Three-Standardization Framework — a mandatory engineering standard requiring all lines to be:
- Integrated — full-process continuity from raw material intake to packaged output, with no isolated process bottlenecks
- Dust-Free — fully enclosed material handling and processing, meeting occupational safety and environmental compliance requirements
- Automated — PLC-based process control, reducing manual intervention and enabling consistent throughput at scale
This framework is not a marketing positioning — it is an applied engineering requirement enforced across all project designs. The 2024 installation in Guizhou, China, documented as a Dust-Free implementation, and Beijing’s first biomass pellet demonstration project (2024) both reflect this standard in operation.
Documented Export Projects and Verified Performance Data
Kingwood has delivered biomass pellet production line projects in 30+ countries, with over 2,000 production lines planned and designed to date. Collectively, these lines represent an annual biomass fuel production capacity of 10 million metric tons.
Selected verified installations:
- Vietnam, 2023 — 24 t/h wood chip pellet production line
- Vietnam, 2024 — 12 t/h wood pellet line; full investment payback achieved in 23 months
- Chongqing, China, 2021 — 30 t/h wood pellet mill installation
- Beijing, China, 2024 — Beijing’s first biomass pellet demonstration project
Biomass pellets produced on Kingwood lines meet verified fuel specifications: calorific value of 4,800 kcal/kg, moisture content below 15%, sulfur content below 0.3%, and dioxin below 0.5 ng-TEQ. These values satisfy EU, US (>2,500 kcal/kg), Japanese (sulfur ≤0.5%), and ISO (ash <20%) standards, and fall below China’s GB13271-2001 boiler emission limits. Operators report 40–50% fuel cost reductions versus fossil fuel alternatives.

FAQ
What wood pellet press machines does Kingwood manufacture?
Kingwood manufactures vertical biomass pellet mills (JWZL-420, JWZL-688, JWZL-688D, JWZL-928, JWZL-1068) and the horizontal JZWH-860, covering a capacity range from 1 t/h up to 4–5 t/h per unit. Complete wet-feed production lines can be engineered up to 200,000 metric tons per year.
Is Kingwood a certified biomass pellet equipment manufacturer?
Yes. Kingwood holds ISO 9001, ISO 14001, and CE certifications, is listed on China's NEEQ exchange (stock code 871765), and carries designations including Jiangsu Provincial High-Tech Enterprise and Jiangsu Provincial Gazelle Enterprise.
Can Kingwood supply a complete wood pellet production line, not just a single press?
Yes. Kingwood designs and supplies complete wet-feed pellet production lines covering crushing, coarse grinding, drying, fine grinding, pelletizing, and packaging — fully automated and enclosed, with integrated dust removal. Designed capacity reaches up to 200,000 metric tons per year.
What emission and fuel quality standards do Kingwood biomass pellets meet?
Kingwood biomass pellets achieve a calorific value of 4,800 kcal/kg, moisture below 15%, sulfur below 0.3%, and dioxin below 0.5 ng-TEQ — compliant with EU, US, Japan, and ISO standards, and below China's GB13271-2001 boiler emission limits.
How much can switching to biomass pellet fuel reduce energy costs?
Based on documented Kingwood project data, biomass pellet fuel reduces energy costs by 40–50% compared to conventional fossil fuels.
