Pellet making is a subject that is interesting more and more people, particularly in the area of producing fuel pellets, for example wood pellets.
So what is involved in pellet making, and what materials can be processed into pellets. Making wood pellets today is what most people are interested in. Due to the general rising price of oil and gas and concerns over global warming, wood pellets have seen a rapid growth. With the increase in the purchase of pellet stoves and boilers more people are interested in how this fuel is made, and is it possible to make the pellets on a small scale. The next few years will see a dramatic rise in large scale pellet production plants, however there is also an opportunity to produce wood pellets on a small scale. To produce wood pellets the wood must have a low moisture content, or drying equipment will be required. The wood must also be reduced to a small uniform sized dust before it can be compressed into a pellet. Once a dry uniform dust is obtained the material can then be processed into pellets. Through sufficient heat and pressure the wood is shaped into pellets. Other raw materials besides wood can also be used in pellet making, see left for examples. This includes purpose grown energy crops such as miscanthus, switchgrass and hemp. It also includes agricultural waste materials left over from food production, for example wheat straw, barely straw and corn stalks. All of these raw biomass materials can be processed for making pellets. Making pellets from these biomass materials is often easier and has a lower power consumption than producing wood pellets, so are worth considering.
