biomass pellet mill
Biomass is refers to all kind of plants or plant-derived materials like trees, grasses, crops, etc. As a renewable energy source, biomass can either be used directly for combustion to produce heat, or indirectly after converted into various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.
The most popular way in recent years is to make biomass into pellets, which is realized by a set of biomass pellet mill.

Why use biomass pellet mill?
The original shape biomass can be directly burned to get heat, but it may cause some bad results, such as:
- Not fully burned and high ash content,
- more air pollutants emission of oxy carbide and sulfur oxide,
- takes quite some space for burning, but release not much heat,
- not easy to transport or store because of large volume, or loose form,
- some can’t be burned in virgin state, such as sunflower husk, peanut shell, etc.
By using a set of biomass pellet mill, all the above problems can be solved. When made into pellets, there is less ash, less air pollutants, easy to transport or store, and all can be burned in stoves.
Advantages of biomass pellets
Biomass pellets have the following advantages:
- Higher density
- Wide range of raw materials like straw, grass, hay, wood, sawdust, peanut shell, sunflower husk, rice husk, alfalfa, pine, and many other materials
- Can be fully burned, thus contributing to the environment protection. The ash is also a good source of fertilizer for farmland
- Low cost. If you have some kind of biomass at hand, you do not need to worry about the cost of raw materials.

Does biomass pellet mill cost too much?
Actually the cost of biomass pellet mill depends on your capacity requirement and other auxiliary machines. In fact, if you count in a long time as 3-5 years or even longer (which can be the service-life of a biomass pellet mill), and the productivity all together, it is just a small amount of cost per year. You can make pellets not only for own use, but also for sale to make profit!
What’s more, if you choose a reliable biomass pellet mill manufacturer as GEMCO, you will also save a sum of money on purchasing the pellet mill, since we are the manufacturer, and we have the most competitive price and professional service and help.
