The Abundance of Pellet Press Machine Raw Material

The beauty of the pellet mill is that there is an abundance of pellet press raw material especially for pellet fuel production. Due to this fact, more and more families prefer buying a small pellet press to make their own pellets. Besides, compared with electricity and gas, fuel pellets is more affordable and effective. Pellet press is not that hard to operate as it may seem, all you need is a complete guide for pellet press beginners. However, perhaps next to the equipment needed in this business, the next most important thing is the raw material that is needed for this. Before feed the materials into the machine, they must be well prepared such as dry the material to certain moisture content. The drying part can be done at the pellet mill or at a different location and then it can be transported, ready for pelletizing to the mill. In areas renowned for pellet fuel production, there are drying entities set up whose work is to dry and condition the materials to the right state before pelletizing can take place.

Among plenty of biomass materials, rice husk, grass, straw, corn stalk and sawdust are the most common use raw materials for pellet production. There many more types of raw materials that you can use for pellet fuel production. However, the choice will depend on where you come from and what is readily available there. Asia for example, rice is the main grain that farmers planted. So in Asia, rice straw becomes the most popular biomass material for pellet press machine. In some other countries where there is abundant forest resource, sawdust and wood co-products become the most common raw mateiral. 

The pellet press raw material for the process has to be gathered in advance, and then after conditioning to the right moisture, note that the best moisture content for all raw materials should be 15%. This is the best moisture content if the pellets produced are to be of very high quality. However, wood material needs no binders since they have already contained kind of glue that can bind the material together - lignin. 

For some materials, chipper or crush machine is needed. In chipping, if the wood materials are thicker than 50mm wide and 10mm long, they have to be resized to smaller sizes. After this, you need to use a crush machine to grind the raw material into powder form so that they are available for pelletizing. Then, make sure the moisture percentage is no more than 15%. Most pellet presses have a rotary dryer, which is really a combination of a stove and a dryer. This can reduce the moisture content from, say 65% to about 10%. Remember that the raw materials especially if they are wood will have high moisture content and therefore they must be dried before they can be fed into the pellet mill, where more processes will take place.

Remember that the quality of the pellets that one produces will depend on the type of pellet press raw material used. For example, if the raw material was hard wood, then the pellets will be indeed very high quality.
