What fuel quality do the finished biomass pellets achieve?

Biomass 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.

China Wood Pellet Press Machine Manufacturer — Kingwood

Kingwood: Industrial Wood Pellet Press Machine Manufacturer Since 1999

Jiangsu Kingwood Industrial Co., Ltd. (NEEQ: 871765) is an industrial-grade wood pellet press making machine manufacturer headquartered at #568 Hongsheng Road, Liyang City, Jiangsu Province, China. Founded in 1999 and publicly listed on China’s National Equities Exchange and Quotations, Kingwood operates from a 31,200 m² facility — 25,000 m² of production floor and 6,200 m² of engineering and office space — within Liyang Zhongguancun Industrial Park.

With 27 years of focused R&D in biomass pellet equipment and a team of 20 dedicated R&D experts, Kingwood has moved well beyond single-machine supply. The company now engineers, manufactures, and commissions complete biomass pellet production lines for clients across 30 countries, having planned and designed more than 2,000 production line projects with a combined annual output capacity exceeding 10 million metric tons of biomass fuel.

Kingwood holds ISO 9001 and ISO 14001 certifications, CE marking, and is designated a Jiangsu Provincial High-Tech Enterprise and Jiangsu Provincial Specialized & Innovative Niche Leader.

Wood Pellet Press Machine Models and Capacity Range

Kingwood’s core product line centers on the ring die pellet mill — the preferred configuration for industrial-scale, continuous biomass pellet production. The range spans both vertical and horizontal configurations to match facility layouts and throughput requirements.

Vertical Ring Die Pellet Mills (JWZL Series):

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 operations requiring higher throughput, Kingwood engineers parallel multi-unit configurations and complete integrated lines. A 24 t/h wood chip pellet production line was delivered and commissioned in Vietnam in 2023. A 30 t/h pellet production line in Chongqing, China has been in operation since 2021. Complete lines are engineered to annual capacities up to 200,000 metric tons.

Auxiliary equipment available for line integration includes the hammer mill, drum chipper, drum dryer, counter-flow cooler, and pellet packaging machine.

Complete Wet-Feed Biomass Pellet Production Lines

Single pellet press machines address replacement and capacity-expansion needs. However, Kingwood’s principal offering for new projects is the complete wet-feed production line — a fully engineered system designed to accept high-moisture biomass input and deliver finished, packaged pellets at the output end.

The processing sequence covers six stages: crushing, coarse grinding, drying, fine grinding, pelletizing, and packaging. All stages are integrated with automated controls, enclosed material handling, and dust removal systems — eliminating the environmental and safety issues common in open-floor biomass processing facilities.

This architecture reflects Kingwood’s proprietary Three-Standardization Framework, which mandates three design principles across all production line projects:

Integrated — all process stages unified under a single control architecture
Dust-Free — fully enclosed conveyance and processing to suppress airborne particulate
Automated — PLC-based operation reducing manual intervention and improving consistency

The Dust-Free pillar was implemented in a 2024 project in Guizhou, China, where Kingwood constructed a fully enclosed biomass pellet workshop meeting both environmental compliance and worker safety requirements. Beijing’s first biomass pellet demonstration project, also completed in 2024, applied the full Three-Standardization Framework under municipal environmental scrutiny.

Finished pellets produced on Kingwood lines meet internationally recognized quality benchmarks: calorific value of 4,800 kcal/kg, moisture content below 15% (EU standard), sulfur content below 0.3% (within Japan’s ≤0.5% threshold), ash content below 18% (below ISO’s <20% limit), and dioxin content below 0.5 ng TEQ/m³ (well within China’s GB ≤1.0 ng TEQ/m³ standard). Operating costs for biomass fuel run 40–50% lower than equivalent fossil fuel consumption.

Wholesale Supply and Global Project Support

Kingwood supplies wood pellet press machines and complete biomass pellet lines to industrial buyers in 30 countries. The company’s export experience spans Southeast Asia, South Asia, Europe, and other markets requiring both machine supply and turnkey engineering.

For buyers sourcing through wholesale or OEM channels, Kingwood provides factory-direct pricing, technical documentation in English, and dedicated engineering consultation for line layout, civil works reference drawings, and process integration. A 12 t/h production line in Vietnam completed in 2024 returned full capital investment within 23 months — a benchmark the project team uses in ROI modeling for prospective clients.
