Can Kingwood supply a complete wood pellet production line?

Yes. Kingwood designs and supplies wet-feed complete lines covering crushing, coarse grinding, drying, fine grinding, pelletizing, and packaging, with automated controls, enclosed processing, and integrated dust removal. Maximum designed capacity reaches 200,000 metric tons per year.

What certifications does Kingwood hold?

Kingwood holds ISO 9001, ISO 14001, and CE certifications, and is recognized as a Jiangsu Provincial High-Tech Enterprise and Jiangsu Provincial Specialized & Innovative Niche Leader, among other provincial and national credentials.

Which countries has Kingwood supplied equipment to?

Kingwood has supplied biomass pellet equipment to customers in 30+ countries. Documented project references include Vietnam (12 t/h and 24 t/h lines) and multiple sites across China including Beijing and Chongqing.

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

Pellets produced on Kingwood lines typically 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.

What is Kingwood's Three-Standardization Framework?

The Three-Standardization Framework is Kingwood's proprietary production philosophy built on three pillars: integrated production lines, dust-free production lines, and automated production lines. It drives quality consistency and differentiates Kingwood's engineering approach.

Where is Kingwood located and how large is its facility?

Kingwood operates from #568 Hongsheng Road, Liyang Zhongguancun Industrial Park, Liyang City, Jiangsu Province, China. The facility covers 31,200 m² total — 25,000 m² of production space and 6,200 m² of office space.

Wood Pellet Press Machine: China Manufacturer

Industrial-Grade Wood Pellet Press Machines from a Verified China Manufacturer

Jiangsu Kingwood Industrial Co., Ltd. — operating under the brand name Kingwood — has manufactured biomass pellet equipment since 1999. Headquartered at Liyang Zhongguancun Industrial Park in Jiangsu Province, the company holds ISO 9001, ISO 14001, and CE certifications and is publicly listed on the NEEQ exchange under stock code 871765.

With 27 years of focused R&D, a team of 20 dedicated R&D experts, and a 25,000 m² production facility, Kingwood operates at a scale suited to B2B procurement — whether for a single pellet mill or a fully integrated production line designed to process 200,000 metric tons of biomass per year.

Kingwood equipment has been deployed in 30+ countries across Asia, Europe, and beyond. The company has planned and designed more than 2,000 production line projects, underpinning an aggregate annual biomass fuel capacity of 10,000,000 metric tons across its installed base.

Ring Die Pellet Mill Models: Capacity and Configuration Options

Kingwood’s core product range covers both vertical and horizontal ring die pellet mill configurations, designed for continuous industrial operation on wood chips, agricultural residues, and other lignocellulosic feedstocks.

Vertical 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 pellet mill:

Model	Rated Capacity
JZWH-860	4–5 t/h

Each model uses a ring die pressing mechanism suited to high-throughput biomass pellet production. For buyers evaluating multi-press installations or parallel-line configurations, Kingwood’s engineering team provides layout and load-balancing consultation as part of the project design process.

Auxiliary equipment — including hammer mills, drum chippers, drum dryers, counter-flow coolers, and pellet packaging machines — is available as part of a complete line package or as standalone supply.

Complete Wet-Feed Biomass Pellet Production Lines

For operators processing green or high-moisture biomass, Kingwood’s wet-feed complete production line handles the full process sequence: primary crushing, coarse grinding, drum drying, fine grinding, pelletizing, cooling, and packaging. The line is fully automated, runs in an enclosed configuration to control dust and emissions, and integrates dust removal at each transfer point.

This configuration directly addresses the operational compliance requirements increasingly imposed on biomass fuel producers in China, the EU, and other regulated markets. Kingwood’s proprietary Three-Standardization Framework — built on integrated, dust-free, and automated production lines — is the engineering foundation behind every complete line design.

Documented deployments include:

A 24 t/h wood chip pellet production line in Vietnam (2023)
A 12 t/h wood pellet line in Vietnam (2024) with a documented payback period of 23 months
A 30 t/h installation in Chongqing, China (2021)
Beijing’s first biomass pellet demonstration project (2024)
A dust-free biomass pellet workshop in Guizhou, China (2024)

Pellet Fuel Quality Standards Met by Kingwood-Equipped Lines

Biomass pellets produced on Kingwood lines are designed to meet the fuel quality thresholds required for boiler and industrial combustion applications across multiple regulatory frameworks:

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

For industrial buyers replacing coal or heavy fuel oil, Kingwood-equipped biomass fuel operations typically achieve fuel cost reductions of 40–50% versus fossil fuel alternatives.
