Corn Stover Pellet Mill

Superior fuel pellets are catching on in many regions where high coal and fuel oil costs make pellet heat very feasible. As the pellet industry is booming, more and more biomass materials are considered as alternative energy for replacing traditional fuel.
Corn Stover—Good Choice for Making Biomass Pellets
Corn stover is usually regarded as a “waste” material or a by-product from corn grain production. It consists of stalk, leaves, cob and husk, which are left in the field after the harvest of grain. Every year, a large number of corn grain are harvested, whereas each 35-45 bushels of corn grain per acre will produce approximately one ton corn stover per acre. What’s more important, corn stover has many important characteristics, it is typically composed of 38% cellulose, 26% hemi-cellulose, 19% lignin, 4% acid detergent lignin, 5% crude protein and 6% ash. The lignin and water-soluble carbohydrates in stover make it easier to be pelletized without binders than some energy crops, such as  switchgrass or miscanthus with low lignin content. It is clear that the corn stover as biomass energy is renewable and it will do great help if we can utilize this endless energy.


What are the Benefits of Turning Corn Stover into Biomass Pellets?
1.Increased yield of corn makes surplus supply of corn stover available. Many farmers treat them as useless materials and often burn them off directly, which causes serious air pollution. If the farmer process this waste in a pellet mill, it can not only solve this tricky problem but generate additional income through producing free fuel for their own energy needs.
2.Corn stover pellets contain 7000 to 7500 BTUs per pound and actually produce less ash and less corrosive than many other biomass pellets such as those made from straw and hay.
3.Corn stover pellets made by our corn stover pellet mill are smooth, dense and hard, they can be used for home heating or cooking. Additionally, you can also make profit by selling them if there are some extra pellets.



Flat Die Corn Stover Pellet Mill
To turn corn stover into biomass pellets, a corn stover pellet machine is necessary. Corn stover pellet machine is also called corn stover pellet mill, corn stover pellet making machine, or corn stover pellet press. Usually the corn stover pellet mill is designed with flat die and mainly suitable for small scale pellets production. What’s more important, you can make corn stover pellets at home. Equipped with alloy steel components, our corn stover pellet press has good durability, high efficiency and high yield. It’s also important to remember that this corn stover making machine has long usage life, and continuous production can be realized.

Pelletizing Process of Corn Stover Pellets
Crushing – Drying – Pelletizing – Cooling – Packing
1. Crush the corn stover into powder with diameter of less than 3mm by hammer mill.
2. Before making corn stover pellets, you need to make sure that the moisture content of crushed corn stover is less than 15%. If not, they need to be dried in the sun or by a dryer machine.
3. Now it is the right time to pelletize the corn stover. In a pellet machine, corn stover will be compressed into columned granules with uniform length.
4. The corn stover pellets discharged from the pellet machine are of high temperature and moisture, so these pellets need cooling. You can choose free cooling or with a pellet cooler.
5. Packing and storing the final pellets into a silo or bags in case of dust, rain or mildew.
