Flat Die Pellet Machine: The Efficient Compressor for Biomass Conversion
In the global wave of renewable energy, flat die pellet machines are becoming core equipment for biomass pellet production with their unique compression technology. This efficient machinery can convert loose agricultural waste, forestry by-products, and other biomass raw materials into solid pellet fuels with high density, high calorific value, and easy storage and transportation through high-pressure physical compression, contributing significantly to clean energy development.

Flat Die Pellet Machine: The Art of Pressure and Friction
The core working principle of flat die pellet machines lies in the synergistic action between the horizontally placed die plate (flat die) and vertically rotating press rollers. When raw materials are fed into the machine, the press rollers roll on the surface of the flat die, forcing the raw materials into the forming holes on the flat die. Under immense pressure (typically 50-150 MPa) and frictional heat, the lignin in the raw materials softens, acting as a natural binder that firmly bonds the biomass particles together.
This compression process requires no chemical binders, relying entirely on physical pressure and the inherent properties of the raw materials for forming. The forming holes on the flat die can be designed with different diameters (typically 6-12 mm) as needed to produce pellets of corresponding specifications. The entire process is continuous, efficient, and relatively low in energy consumption.
The unique advantage of flat die pellet machines lies in their simple structure and strong adaptability. Whether it's fresh raw materials with high moisture content or dry crushed materials, efficient and stable pellet production can be achieved by appropriately adjusting process parameters.
