Making biomass pellets is a process which can be achieved on both a large as well as small scale. As by means of most industries, the development of large scale biomass pellet plants at this time dominates the biomass pellet manufacture market. Yet, there is a mounting number of biomass pellet machines accessible for even small residence owners to use to make there own pellet energy. However there is very little information obtainable on which wood pellet making machine is suitable to process dissimilar biomass materials for energy pellets.

The pellet appliance has been an industrial tool for over a hundred years. The first intended use of the pellet machine was to create a superior animal feed. The idea was to process the grasses, straws, vitamins along with minerals into pellet form. The compensation of such were that it would be much cheaper to transportation the feed, much easier to get the animals to take the required mineral plus vitamins as well as eat the correct amount of food to achieve the best price to profit ratio. Pellet machines were very successful in the animal feed industry plus today, pelleted animal feed in the market leader as a way to control feed to stock animals.
On the other hand, the type along with design of pellet appliance used form making animal feed, is not the same type of pellet appliance that can be used for making a biomass pellet. Wood as a raw matter is very different to straws in addition to grasses. Biomass has a much higher density plus stronger fibres. These differences mean biomass performs very differently in the pellet machine. To compress a matter into a pellet requires ample heat in addition to pressure to melt the materials untreated lignin. Due to the increased density of biomass, means that biomass has to reach a higher heat than grasses in addition to straws to form a pellet. Also, owing to the increased density of the wood, more power is needed to compress the wood owing to the die template in the pellet machinery. This generally means the pellet machine needs to be geared down to provide more torque. There are a mixture of other changes in design of the pellet appliance to compress wood into pellet form.

Not all wood pellets are the same, depending on the type of wood residue used to produce the pellets the ash content of the pellets can change. For example, to produce a pellet by as little ash as probable, practically all bark must be removed from the pellets. In many cases yet, this is not practical, in addition to also bark contains a lot of fuel. However the pellets produced will have a higher ash content, plus this may limit the number of pellet stoves plus boilers the pellets can be burnt in successfully. Generally pellet stoves as well as boiler which have a drop down design will not be able to burn the pellets. Therefore it is much better form consumers to avoid this design of pellet burner. When making a wood pellet, before placing the matter into the machinery, it is very important to monitor the moisture content as well as make sure it is dry sufficient but still have ample moisture to melt the natural lignin to help bind the biomass pellet together.
