This RUF Lignum Classic Wood Press is an industrial briquetting press — sometimes referred to as a wood briquette machine or log maker — designed to compress wood waste into uniform rectangular briquettes suitable for sale as fuel or biomass. RUF is a well-established German manufacturer with decades of specialisation in briquetting technology, supplying machines to the timber processing, woodworking, and biomass energy industries worldwide.
This 2024 machine is offered used and is described as ready for immediate delivery. An important condition of supply is that the press must be paired with at least one system component — such as a chipper, cutting mill, hammer mill, screw conveyor, conveyor belt with overbelt magnet, or suction unit — which must be sourced accordingly.
On the production side, the press achieves a throughput of up to 425 kg per hour, though actual output depends on the bulk weight of the raw material; the quoted figure is based on a bulk weight of 200 kg per cubic metre. Briquettes produced measure 150 × 60 mm in cross-section, with a length that is adjustable between 40 and 105 mm, allowing some flexibility in the finished product. Pressing pressure reaches approximately 1,700 kg/cm², generated through a hydraulic system incorporating both a pre-compressor and a main compressor, backed by a 260-litre oil tank. The pump motor is rated at 30 kW and runs on 400 V, 50 Hz, three-phase power, with total power consumption for the press standing at approximately 33 kW.
Control is handled by a PLC unit with a touch display, housed in a dustproof switch cabinet, and all cylinders can also be operated manually. The press is built for continuous 24-hour operation and is noted for its compact footprint, low maintenance requirements, and high energy efficiency attributed to its hydraulic design. Standard equipment includes a packing table with drawer and a top-mounted silo with discharge.
Raw material entering the press must meet specific requirements: moisture content (atro) must fall between 6% and 15%, maximum chip dimensions are 20 × 2 × 2 mm, the material must be entirely free of metals and mineral contaminants such as sand or stones, and the installation environment must be maintained at a minimum ambient temperature of plus 8 degrees Celsius. The machine is located in Germany.
