Import Biomass Screw Extrusion Briquette Machine — Buy in wholesale FOB from Supplier in China

The Biomass Screw Extrusion Briquette Machine from Zhengzhou Dingli New Energy Technology Co., Ltd. is a screw-extrusion type densification unit designed to compress pulverised biomass feedstock into solid cylindrical briquettes. The machine employs a heated die and tapered screw to generate the 40-60 MPa typical compression pressure needed to lignify and bind cellulosic material without external binders. The source indicates processing capability for wood chips, agricultural residues and mixed biomass waste, though the supplier does not specify rated motor power, hourly throughput or screw diameter, and buyers should confirm these directly.

Screw extrusion briquetting relies on the thermoplastic behaviour of lignin at 200-250 degrees Celsius under friction and pressure. The typical screw tip speed of 300-600 rpm generates sufficient heat to soften natural binders, producing briquettes with standard density of 1.0-1.4 g per cubic centimetre and calorific value 16-19 MJ per kg depending on feedstock. Die wear rates vary with silica content in raw material; hardened alloy dies are standard for abrasive agricultural residues such as rice husk. The machine frame and hopper are typically fabricated from carbon steel with hardened screw flights, though the supplier's exact material grades are not stated in the listing.

Primary buyers include biomass pellet plants, agricultural co-operatives, sawmills and renewable energy project developers in Southeast Asia, Africa and Eastern Europe. The briquettes suit domestic stoves, industrial boilers and gasification units. The source mentions FOB and CIF shipping terms, flexible MOQ and ISO certification, but does not state the actual minimum order, confirmed price band or lead time. Buyers should request a formal quotation specifying screw geometry, motor rating, die specification and wear-part availability before committing.

Zhengzhou Dingli New Energy Technology Co., Ltd. is located at No.12 Hongye Road, Zhengzhou, Henan Province, China, with postal code 450001. The company holds a harbor trust tier on the platform. The response rate is listed as 0.00 percent with zero average response hours, which indicates no response data is available rather than active non-response. Buyers should test communication channels directly before relying on platform metrics.

The supplier's profile does not state year of establishment, registered capital, factory size, headcount, annual revenue or specific export markets. The source description frames the company as offering flexible MOQ, competitive pricing and efficient shipping terms, but provides no verifiable figures. No client references, patent holdings or additional certification details beyond ISO are present in the listing. Buyers should conduct independent due diligence including factory audit and reference checks.
