Corn Stover Pellet Machine

Corn Stover Pellet Machine 

Corn stover is the by-product of corn harvesting, plants left in a field after harvest and consists of the residue: stalk; the leaf, husk, and cob remaining in the field following the harvest of cereal grain. Stover makes up about half of the yield of a crop and is similar to straw. It is one of the sustainable biomass energy of largest potential. However, due to corn stover’s low bulk density, transportation costs are very high. In order to reduce the costs of handling, storage and transportation of corn stover, densification is the way. The most common densification methods of corn stover are stacking, baling, briquetting and pelletizing. Pelletizing is the most effective method.

Before you start making pellets with corn stover, you should gather the materials together and dry them in the sun for a few days. Then pelletizing corn stover mainly involves the using of the hammer mill to reducing the size of corn stover into less than 5mm and corn stover pellet machine to extrude pellets. Due to its low bulk, the pelletizing corn stover is not so easy as pelletizing wood, so the unique pellet machine for converting corn stover into fuel pellets is necessary. For farmers and small scale corn stover pellets manufacturers, the most suitable corn stover pellets machine is flat die corn stover pellet mill such as AZSPLM200 electric flat die corn stover pellet machine and AZSP-200D diesel flat die corn stover pellet machine offered by us.

The main technical parameters are as follows

The corn stover pellets made by the corn stover pellet mill are in the form of cylinders with the diameters of 6 to 12mm and lengths of 13 to 25mm. If you want to use corn stover pellets for home heating, cooking or farm heating, the best diameter is 6mm, and if you want to make corn stover pellets for industrial use, the best diameters are 8mm and 10mm.

Suggestions for the Corn Stover Pellets Producers

To get the most out of corn stover pellets, it is recommended that the corn stover pellet plant be located within 50 miles of the feedstock supply, and the finished corn stover pellets should not have to travel more than 200 miles to get to their point of use. Corn stover pellets can be used wherever wood pellets are used, such as in cogeneration plants, gasification and cellulosic ethanol production facilities, or in home pellets heaters.
