What certifications does Kingwood hold as a wood pellet press machine factory?

Kingwood holds ISO 9001, ISO 14001, and CE certifications, and is recognized as a Jiangsu Provincial High-Tech Enterprise, Jiangsu Provincial Gazelle Enterprise, and a member of the China Biomass Energy Industry Alliance as Deputy Director Member Unit.

How many countries has Kingwood exported biomass pellet equipment to?

Kingwood has served customers in 30+ countries and has planned and designed over 2,000 production line projects globally since 1999.

What feedstocks can Kingwood's wood pellet making machines process?

Kingwood's wet-feed production lines handle high-moisture biomass feedstocks including wood chips, agricultural residues, and forestry waste through integrated crushing, drying, grinding, pelletizing, and packaging stages.

What fuel quality do biomass pellets produced on Kingwood lines achieve?

Pellets produced on Kingwood lines achieve a calorific value of 4,800 kcal/kg, moisture content below 15%, sulfur content below 0.3%, and ash content below 18% — compliant with EU, ISO, and China GB standards.

Is Kingwood listed on any stock exchange?

Yes. Jiangsu Kingwood Industrial Co., Ltd. is publicly listed on the NEEQ (National Equities Exchange and Quotations) under stock code 871765.

China Wood Pellet Press Machine Manufacturer — Kingwood

Kingwood: China Wood Pellet Press Machine Manufacturer Since 1999

Jiangsu Kingwood Industrial Co., Ltd. — operating under the brand Kingwood — is a China-based wholesale wood pellet press making machine manufacturer headquartered at #568 Hongsheng Road, Liyang City, Jiangsu Province, within Liyang Zhongguancun Industrial Park. Founded in 1999, the company brings 27 years of focused R&D to the biomass pellet equipment sector and is publicly listed on the NEEQ under stock code 871765.

Kingwood operates a 31,200 m² facility — 25,000 m² of production floor plus 6,200 m² of office and engineering space — and employs 20 dedicated R&D experts. The product range covers ring die pellet mills, hammer mills, drum chippers, drum dryers, counter-flow coolers, and fully integrated wet-feed biomass pellet production lines scaled up to 200,000 metric tons per year.

Ring Die Pellet Mill Product Line for Industrial Buyers

Kingwood’s core product is the ring die pellet mill, available in vertical and horizontal configurations sized to match plant throughput requirements:

Model	Type	Capacity
JWZL-420	Vertical	1–1.5 t/h
JWZL-688	Vertical	2–2.3 t/h
JWZL-688D	Vertical	3–3.5 t/h
JWZL-928	Vertical	4–5 t/h
JWZL-1068	Vertical	Contact sales
JZWH-860	Horizontal	4–5 t/h

For buyers sourcing wholesale wood pellet making machines for multi-machine installations, Kingwood engineers complete process configurations that integrate auxiliary equipment — including hammer mills for coarse size reduction, drum chippers for log and branch preprocessing, drum dryers for moisture control, and counter-flow coolers for pellet stabilization before packaging.

All equipment lines are built under Kingwood’s proprietary Three-Standardization Framework, which mandates integrated production, dust-free enclosed processing, and automated control across every line. This framework is the basis for Kingwood’s differentiation in the industrial biomass pellet equipment market and is embedded in every project specification.

Wet-Feed Production Lines: Technical Scope and Compliance

Kingwood’s complete wet-feed pellet production lines are engineered to handle high-moisture biomass feedstocks — wood chips, forestry residue, crop stalks — without pre-drying at intake. The process sequence is: crushing → coarse grinding → drying → fine grinding → pelletizing → packaging, all within a fully automated, enclosed environment with integrated dust removal.

Lines are designed for outputs from small industrial installations up to 200,000 metric tons per year. Pellets produced on Kingwood lines consistently meet international fuel quality benchmarks:

Calorific value: 4,800 kcal/kg
Moisture content: <15% (meets EU standard)
Sulfur content: <0.3% (below Japan ≤0.5% threshold)
Ash content: <18% (below ISO <20% limit)
Dioxin emissions: <0.5 ng TEQ (below China GB ≤1.0 ng TEQ)
All combustion emission indicators comply with GB13271-2001, China’s national boiler air pollutant emission standard

Biomass fuel produced on these lines delivers a 40–50% cost reduction versus conventional fossil fuel alternatives, a figure that directly supports project ROI calculations for industrial operators and energy utilities. See the Vietnam 12 t/h wood pellet line case study for a documented 23-month payback period example.

Export Reach and Project Track Record

Kingwood has supplied wood pellet press machines and complete production line engineering to customers in 30+ countries and has planned and designed more than 2,000 production line projects since 1999. Verified international deployments include a 24 t/h wood chip pellet production line in Vietnam (2023) and a 30 t/h installation in Chongqing, China (2021).

Domestic reference projects include Beijing’s first biomass pellet demonstration project (2024) and a dust-free biomass pellet mill workshop in Guizhou (2024), which showcases the dust-free pillar of Kingwood’s Three-Standardization Framework in a live production environment.
