Import Biomass Briquetting Machine — Buy in wholesale FOB from Supplier in China

The biomass briquetting machine from Zhengzhou Dingli New Energy Technology Co., Ltd. is a mechanical press designed to compress fluffy agricultural residues into dense cylindrical or square briquettes. The unit processes straw, sawdust, grass, and wood chips with fibre length below 50 mm and moisture content between 12% and 25%, producing briquettes with a finished density of 0.7 to 1.2 g/cm3. The machine integrates a feeding conveyor, briquetting chamber, and discharge section, all controlled via a distribution cabinet. A motor drives the spindle, which rotates pressure rollers against a horizontal ring die to extrude material through square or circular die holes.

The core working mechanism relies on high-pressure mechanical compaction rather than binding additives. Raw material first passes through a cutting or grinding machine to reduce fibre length, then enters the feed port via conveyor. The transmission system transfers rotational force to the rollers, which force material through the horizontal die openings. The nubby extrusion falls from the discharge port as a finished briquette. Typical ring die materials are alloy steel with surface hardening to resist abrasion from silica and lignin present in straw and sawdust. Standard pressure roller clearance and die hole taper vary by material type and required density.

This equipment suits biomass fuel producers, agricultural cooperatives, and wood-processing operations seeking to densify waste streams for transport or combustion. Briquettes reduce volume by up to 90% compared with loose straw, lowering storage and freight costs. Buyers should confirm motor power rating, hourly throughput in kg/h, and die hole specification with the supplier, as these determine compatibility with local raw material availability and desired output shape. The complete production line configuration, including pre-processing equipment, should be discussed to match feedstock characteristics.

Zhengzhou Dingli New Energy Technology Co., Ltd. is located at No.12 Hongye Road, Zhengzhou, Henan Province, 450001, China. The company holds a harbor trust tier on the platform, with a response rate of 0.00% and an average response time of 0 hours. These signals suggest the listing is present but supplier responsiveness has not been recorded or is currently inactive. The profile does not state year of establishment, registered capital, factory size, or number of employees.

The supplier lists biomass briquetting equipment including feeding conveyors, briquetting machines, discharging units, and distribution cabinets. No certifications, patent numbers, or client references appear in the source data. Buyers should verify the company's manufacturing scope, whether it produces the ring dies and rollers in-house or sources them, and request references for installed machines in similar feedstock conditions. Direct factory inspection in Zhengzhou is advisable given the low response signals.
