Production Line Description
Giant King Grass
Giant King Grass is a fast growing, high yield, perennial grass with many applications including bioenergy and animal feed. Giant King Grass is not genetically modified and is not invasive.The fertilizer requirements are modest and no pesticide is required in the current cultivation.

Yield comparison of giant king grass VS corn stalk VS miscanthus
Notes:Giant King Grass has 10 times the yield per acre compared to corn stover. Due to the different growth environment, the above comparison isn’t entirely apples to apples. However, the advantage of Giant King Grass is obvious.
Giant King Grass Compared to Coal Pellets
Notes: Above data shows that Giant King Grass pellets have higher energy density and lower nitrogen, sulfur and chlorine content than coal.
Advantages of giant king grass as raw materials for pellet production
High yield, but low cost
Neither special care nor pesticide is needed.
Little fertilizer is used.
Easy grow and easy to process into bio-fuel, such as pellets.
How To Produce Giant King Grass Pellet?
Giant King Grass Pellet Production Line flow chart
Generally speaking, in order to get the fuel pellets from freshly harvested giant king grass, a series of procedures must be closely followed. The whole production process of giant king grass pellet include raw materials crushing, drying, pelletizing, cooling and packing.
Crushing: The giant king grass for making fuel pellet is 3-5m in height, so it must be crushed first. The grass needs to be crushed into small pieces with the size smaller than the hole diameter of the pellet mill die. Our hammer mill is no doubt a nice choice.
Drying: When pelletizing, the moisture really plays an important role. Too high or too low can affect the final pellet quality. The moisture of freshly harvest grass is approximately 70-75%, which needs to be lowered to around 10% by sun drying or the rotary drum dryer.
Pelletizing: As the core procedure of fuel pellet production, pelletizing directly influence the pellet quality. We have both flat die pellet machine and ring die pellet machine for your selection.
Cooling: Newly pressed pellets are hot and soft, which need to be cooled down to ensure the hardness and durability.
Packing: After cooling, the pellets can be packed according to your requirement.
