What is a Straw Pellet Machine?

A straw pellet machine is a straw pellets molding machine that presses straw materials like corn stalk, cotton stalk, wheat/rice straw, palm fiber, and rice husk, sunflower shells, peanut shells, etc. into biomass pellets. The pressed pellets are mainly used as biomass fuel replacing oil and coal fuel.

Main Steps of Straw Pellets Production

1. Straw Shredding (use shredders to process the straws into smaller pieces);
2. Drying (reduce the straw material’s moisture to the next pelletizing);
3. Grinding (grind the small pieces into powdered materials);
4. Pelletizing (the key step, press the straw materials into straw pellets);
5. Cooling (cool down the output pellets to avoid accumulation of heat that may destroy pellets);
6. Sieving (remove the dusts and crushed pellets);
7. Packing (pack the pellets into bags of required sizes);
8. Electric Cabinet (control equipments).
