Sawdust and Straw Pellet Press GFD-0.4 - Briquetting Technology

PellTech GFD-0.4 Farmer Pellet Press for Sawdust and Straw The PellTech GFD-0.4 Farmer pellet press is designed for producing pellets from wood-based and plant-based materials. The machine uses a rotating flat die and is suitable for processing raw materials with the appropriate particle size. The model can achieve a production capacity of up to 300–400 kg/h. The resulting pellets can have a diameter of 6 mm for sawdust or 8 mm for straw, with an adjustable length of 10–30 mm. This is a technical solution designed to produce pellets with clearly defined parameters, depending on the feedstock and the die used. Technical Specifications The pellet press is equipped with a rotating flat die with a working diameter of 350 mm, a thickness of 45/50 mm, and a rotational speed of approximately 125 rpm. The pressing rollers have a diameter of 175 mm, while the main drive pulley has a diameter of 800 mm and operates with 8 V-belts. Main motor: 1 × 30 kW Total installed power: 30 kW Power supply: Three-phase, 400 V Control coil voltage: 24 V / 230 V, within a tolerance of ±5% Frequency: 50 Hz Machine dimensions (L × W × H): 1,400 × 1,000 × 1,200 mm Machine weight: 1,000 kg The raw material moisture content should be within the 12–16% range, as moisture affects both pellet quality and production capacity. Compatible Raw Materials Wood sawdust (particle size: 1–3 mm) Cereal straw Alfalfa Sunflower husks Manure Other compostable agricultural waste The recommended raw material particle size is 1–3 mm for sawdust and 3–6 mm for straw, supporting pellet production in accordance with the machine specifications.
