Making Hay Pellets with Pellet Mill for Feed and Fuel
What Is Hay Pellet Mill?Hay pellet mill is especially designed for making pellets from hay, including dry grass, straw, alfalfa, and so on. Traditionally hay or hay pellets are used as feed for cattle, rabbit, sheep, etc. But recently, there is an emerging demand of using hay pellets for heat.
First of all, ensure you have plenty materials. Then a feed grinder is needed to make the raw material well prepared for pelletizing (length shorter than 10mm). Then these small particles should be crushed into powder by using a hammer mill (diameter less than 3mm). At last, a dry machine is needed to keep the moisture percentage of the hay around 15%.
How Does Hay Pellet Mill Make Hay Pellets for Feed?
Then the material is available for the hay pellet mill. Feed the hay into the pellet mill, and the powder will be compressed into density pellets. However, this is not the end! The pellets coming out off the pellet mill is very hot (about 85 degrees). You should use a cooler machine to cool the pellets to 35 degrees. After cooling, the pellets need to be packed with a packing machine and then they can be stored for a long time.
Hay pellets made by the hay pellet mill contain many necessary ingredients which many animals such as horses and rabbits need in their growth. Plus, the pellets are easy to store, which allows animals to eat nutritious hay pellets all year round.
Hay Pellets Used as FuelHay pellets used as fuel have some advantages:
- Hay pellet is a kind of green heating source since than produces 90% less greenhouse gases than fossil fuels like coal, and is 10 times under the EPA emission limit.
- Hay pellet has a surprisingly high energy input-to-output ratio of as high as 20:1, while wood has 10:1, and biodiesel has 5:1.
- One pound of hay pellets will produce nearly 8,000 BTUs, which is almost equal to hardwood, and close to the heat that coal releases in combustion. Therefore, it is quite a fantastic heat source.
- Hay is cheap to get and quite plentiful than fossil fuels.
