Coal Powder Ball Press Machine

The Coal Powder Ball Press Machine from Zhengzhou Zhongzhou Briquette Machinery Plant is a four-roller double-press system designed to convert fine coal powder, coke, lignite, and similar waste materials into dense, durable briquettes. The machine operates with adjustable host RPM and a spiral feeding device to ensure consistent material flow. Output briquettes achieve a density sufficient to withstand drops from 150 to 180 cm without breaking, making them suitable for transport and storage. Production capacity ranges from 2 to 30 tonnes per hour, with options for standalone units or full turnkey plants including conveyors and dust control systems.

The machine is engineered for materials with particle sizes under 3 mm, ideally with 30 to 40% of the feed below 1 to 2 mm and no more than 10% exceeding 2 mm. Moisture content must be maintained between 8% and 20% to ensure proper binding and structural integrity of the final briquette. The rollers are constructed with hardened steel, and the housing can be supplied in standard iron casing or customized per request. This design is typical for industrial briquetting systems handling low-grade fuels and metallurgical residues, where high compaction pressure is required to achieve combustion efficiency.

End users include power plants, metallurgical refineries, and waste-to-energy facilities that need to convert coal fines, slag, or desulfurization gypsum into transportable solid fuel. Buyers typically source this machine to reduce waste disposal costs and improve energy recovery rates. The machine is shipped as a complete assembly with basic electrical controls, and installation support is available upon request. Packaging is standard industrial crate with moisture-resistant lining. Lead time and Incoterms must be confirmed directly with the supplier.

Zhengzhou Zhongzhou Briquette Machinery Plant is a manufacturer based in Gongyi, Henan Province, China, specialising in industrial briquetting equipment for coal, metallurgical waste, and energy recovery applications. The supplier is listed as imported with harbor trust tier, indicating verified export activity and compliance with shipping documentation standards.
