Flat Die Pelleting Machine: The optimal choice for small-scale production

Working Principle: The Union of Pressure and Nature The core working principle of the flat die pelleting machine is clever and efficient. After the operator feeds the raw material into the hopper, the press rollers inside the machine begin to rotate, forcing the material against a flat die plate with many small holes. Under the high pressure and the heat generated by friction, the lignin in the biomass raw material (especially plant-based material) softens, acting as a natural binder that tightly bonds the material together. Finally, it is extruded through the small holes, forming uniform cylindrical strands. A cutter then chops these “strands” into pellets of standard length. The entire process essentially mimics nature’s compaction process but greatly accelerates and standardizes it through mechanical force. Core Features: Simple, Flexible, User-Friendly The design of the flat die pelleting machine fully considers the practical needs of small-scale production, boasting several standout features: Simple and Compact Structure: It mainly consists of a flat die, press rollers, a transmission device, and a feeding system. Its mechanical structure is straightforward, and it has a small footprint, making it very suitable for locations with limited space. Wide Raw Material Adaptability: It can handle everything from agricultural waste (straw, rice husk) and feed ingredients (corn, soybean meal) to organic fertilizer materials (livestock and poultry manure). It also offers good tolerance for variations in particle size and moisture content (typically between 10%-20%).
