Operating Principle and Process of Pelleting

Fote Machinery has been known for high-quality and economic flat die pelleting presses for decades. Pellets with a diameter of 2 to 40 mm can be produced with these presses. Do you need constantly uniform, optimally compacted pellets ? There are many pellet machines in our company such as: ring die pellet mill, flat die pellet mill, flat die wood pellet machine. Our machines process also materials which are difficult to compact: powdery, fibrous, lumpy and pasty substancessubstances with different particle sizes, moisture, and bulk density

Pelleting is compressing a product (usually agricultural) through a small hole in a metal die in a process called extrusion. In this process a natural glue called Lignin is released from the cellulose molecules of the raw material. It becomes semi liquid under the heat of extrusion and small amounts of water in the raw material turns into steam and carries the lignin to the surface of the pellet. When the pellet cools it has a shiny surface coating of Lignin that holds the pellet together. Fote machinery pellet mills has the featured with flexible, uerer-friendly, low cost, energy saving and environmental, high quality and excellent performance.

Large pelleting chambers ensure operation without blockages. The roller gap can be adjusted during operation, the dies can be rapidly replaced, and the roller bearings are lifetime-lubricatedAnother common use for pelletized products these days is for energy production. Waste wood products like sawdust are treated to obtain the correct moisture content by drying or humidifying and then extruded into pellets. The pellets are bagged and then burned when needed to generate heat in a special stove called a pellet stove. They are also commonly used in power plants that would normally use coal to generate electricity without generating extra carbon dioxide. Many believe extra carbon dioxide is causing our planet to become warmer. Thus pelleting is considered to be a green project.
