Grass is familiar to everyone, and you can see it everywhere (square lawn, residential green belt and farmland) and anytime in a year. Grass can not only be used for making feed pellets but also can be used for making biofuel pellets. Grass biofuel pellet is a kind of pellet produced by pressing chopped grasses into a form similar to wood pellets. Making pellets from grass cost less than making pellets from wood. Large scale production of grass fuel pellets can be of a benefit to agriculture and the rural economy, as well as ecologically attractive.
Grass pellets are one kind of green energy resource. With the wide distribution and sustainability of raw materials, the biomass pellets have been an available alternative to traditional fuels. Compared with coal and gas, grass pellets are of equally efficiency but lower cost. The most important point is, they can be made at home completely. All you need is a grass pellet mills
Benefits of Grass Pellets
1. The growth and utilization of the fodder are greatly influenced by seasons. Forage turn wither and yellow with less nutrients in winter . Yet, forage grow vigorous with more nutrients so that livestock can’t eat them up in warm seasons. So, in order to make full use of grass in the warm season to make the effect to come true, the livestock and poultry can be fed in winter with the grass pellets conserved in process of mowing, drying, crushing.
2. High transform rate. Feeding the livestock and poultry with the grass feed pellets in winter, we can gain more meat, egg and milk with less forage.
3. Small volume. Grass pellet is only around 1/4 of the raw materials in volume in favorable for storage and transportation. In addition, less dust is beneficial to the health of human and animals.
4. To increase palatability and improve the quality of forage.
For instance, sweet clover possesses a flavor of coumarin which livestock more or less don’t like it. However, it becomes another forage with a strong palatability and high nutritional value.
5. To spread the source of fodder
such as caragana, optimal quinoa, hedysarummaxim. Etc which have the thick branches turn to the favorable forage once processed into the grass pellets after crushing. Moreover, secondary product of other crops such as abortive shell, straw as well as all kinds of leaves also can be processed into grass pellets and feed livestock and poultry.

Grass Pellets Production Process
How to make grass pellets? This is a six steps procedure of pellet production plant that is followed to make awesome and very high quality pellets with exceptionally good output. The process involves the use of grass pellet mills that take the following production stages.
The first stage involves collecting the mowed grass. It is after collecting the materials that one is supposed to lay them in the sun for drying, while laying them in a thin layer after which pilling is done.The second step is starting the grass pellet mill and preheating it for some minutes. This is done to ensure that ones the grass is put inside the machine, the little left moisture is dried. It is also done to melt the lignin part of the grass to allow for gluing which makes the resulting pellets to come together.
Thirdly, a container is put under the chute of grass pellet mill.This container serves as a collecting pit for the resultant pellets.
The fourth step involves adjusting of the moisture content depending on the finished pellets. This process involves accessing the ready pellets where by, if the pellets are crumbly, then the implication is that the pellets are very dry and thus the grass should be mixed with some water. Mushy pellets thus imply that the pellets have high moisture content and so the grass has to be dried longer in the sun.
The fifth step is to cool the cool the pellets in the air before storing. This step prepares them for burning and thus one can comfortably use them as fuel.
The last step is generally collecting the unspent pellets and parking them in bags for future use.
