What pellet press machine models does Kingwood manufacture?

Kingwood produces five vertical ring die pellet mills (JWZL-420 at 1–1.5 t/h, JWZL-688 at 2–2.3 t/h, JWZL-688D at 3–3.5 t/h, JWZL-928 at 4–5 t/h, and JWZL-1068) plus one horizontal model, the JZWH-860, rated at 4–5 t/h.

Can Kingwood supply a complete biomass pellet production line, not just a single machine?

Yes. Kingwood designs and delivers complete wet-feed pellet production lines handling high-moisture biomass through crushing, coarse grinding, drying, fine grinding, pelletizing, and packaging — fully automated, enclosed, and integrated with dust removal — up to 200,000 metric tons per year capacity.

What quality certifications does Kingwood hold?

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

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 is designed to drive high-quality development in the biomass pellet equipment industry.

What fuel quality do Kingwood 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% — meeting EU, ISO, and China GB standards, with all boiler emissions below GB13271-2001.

Which countries has Kingwood supplied equipment to?

Kingwood has supplied biomass pellet equipment and production lines to customers in 30+ countries, with documented projects in Vietnam (12 t/h and 24 t/h lines) and multiple sites across China including Beijing, Chongqing, and Guizhou.

How can B2B buyers source Kingwood pellet press machines wholesale?

B2B buyers can contact Kingwood directly through kingwoodpellet.com for wholesale pricing, custom line design, and technical consultation. Kingwood serves industrial-scale buyers and EPC contractors requiring configured production lines, not retail-quantity orders.

China Wood Pellet Press Machine Manufacturer — Kingwood

Kingwood: Industrial Wood Pellet Press Machine Manufacturer Since 1999

Jiangsu Kingwood Industrial Co., Ltd. is a China-based manufacturer of biomass pellet equipment, operating from a 31,200 m² facility at #568 Hongsheng Road, Liyang Zhongguancun Industrial Park, Jiangsu Province. Founded in 1999 and publicly listed on the NEEQ (stock code: 871765), Kingwood has accumulated 27 years of R&D experience in wood pellet press machines and complete biomass pellet production lines.

The company’s engineering team of 20 R&D experts has planned and designed over 2,000 production line projects to date. Kingwood equipment is operating in 30+ countries, with documented large-scale deployments in Vietnam, China, and Southeast Asia.

Kingwood holds ISO 9001, ISO 14001, and CE certifications and is recognized by the Jiangsu provincial government as a High-Tech Enterprise, a Specialized & Innovative Niche Leader, and a Gazelle Enterprise.

Wood Pellet Press Machines: Model Range and Specifications

Kingwood’s core product line covers vertical and horizontal ring die pellet mills for industrial biomass processing.

Vertical 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 pellet mill:

Model	Capacity
JZWH-860	4–5 t/h

Auxiliary equipment supplied alongside pellet mills includes hammer mills, drum chippers, drum dryers, counter-flow coolers, and pellet packaging machines — enabling Kingwood to serve as a single-source supplier for complete line projects.

For buyers requiring higher throughput, Kingwood’s complete wet-feed pellet production lines are configurable to a maximum capacity of 200,000 metric tons per year. These lines handle high-moisture raw biomass through a sequential process: primary crushing → coarse grinding → drum drying → fine grinding → ring die pelletizing → counter-flow cooling → packaging. The entire line operates under enclosed processing with integrated dust removal and full automation — consistent with Kingwood’s Three-Standardization Framework.

Three-Standardization Framework: The Engineering Basis for Quality

Kingwood’s Three-Standardization Framework differentiates its equipment and line design from standard OEM offerings. The three pillars are:

Integrated production lines — all unit operations engineered as a coordinated system, not assembled from independent components
Dust-free production lines — enclosed material transfer and negative-pressure dust extraction at every processing stage
Automated production lines — PLC-controlled sequencing, real-time monitoring, and reduced manual intervention throughout

This framework is applied in practice: the 2024 Guizhou dust-free biomass pellet workshop and Beijing’s first biomass pellet demonstration project are both documented implementations. In Vietnam, a 12 t/h line commissioned in 2024 achieved investment payback within 23 months.

Biomass Fuel Performance and Compliance

Pellets produced on Kingwood lines meet the following specifications:

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

Compared to coal and heavy fuel oil, biomass pellets produced on Kingwood equipment reduce fuel costs by 40–50% at equivalent thermal output, based on documented operator data.

Wholesale and B2B Procurement

Kingwood supplies equipment on a wholesale and project basis to industrial operators, EPC contractors, and biomass fuel producers. The company does not serve retail or small-batch buyers. Scope of supply ranges from single pellet mill units to complete turnkey production lines designed for specific raw material types, moisture profiles, and annual output targets.
