Wood Pellet Mill

Features of Wood Pellet Mill

Unlike other biomass materials such as straw and grass, wood have a high density because the consist of wood fiber and lignin. That is to say, wood is harder than many other biomass materials. Pellet mill is originally produced for making fertilizer pellets and animal feed from soft materials. However, on the second hand market, lots of feed pellet mills are sold as wood pellet mills by distributers in order to make bigger profits. Many customers who are planning to make wood pellets are given the wrong machine. Once they start the mill, they will find this machine cannot deal with wood material. To avoid buying the wrong mill, you need know the difference between wood pellet mill and other pellet machines. First of all, wood pellet mill can supply a higher power than other machines so that the hard wood can be pressed into density pellets of high quality. Secondly, wood pellet mill operates a much lower speed than feed pellet mill machine and other machines used to pelletize low density materials. The reason for this is a lower speed can increase the torque to the mill effectively and also have enough time to make sufficient compression in the pellet die template. Last but not least, wood needs a higher temperature to release the lignin, kind of natural binding agent.

Wood Pellet Mill and Heating Units

Compared with the raw form, wood pellet fuel has many advantages. Each wood pellet contains the same value of energy because of uniform shape, size, high density and low moisture content. This means with wood pellets, heating system can easily control the feed rate of the fuel, so that a specific and consistent temperature could be achieved. However, this is impossible for log heating systems and also very difficult for wood chip heating systems. To sum up, wood pellets produced by wood pellet mill are the ideal fuel for heating. That is also the reason why pellet stoves and boilers are getting more and more popular.

The Truth of Making Wood Pellets

It is wrong to think wood pellet making is simply about putting materials into a wood pellet mill. Pellet making is more than just knowing how to operate pellet mills. The raw material needs to be well prepared before start your wood pellet mill. Ensure the materials are crushed to correct particle size by hammer mill and dry the materials to an appropriate moisture content by dryer machine or natural wind and sunshine.
