How To Make Wood Pellets – Wise Investment

How to make wood pellets at home

We have recently seen how efficient that pellets stove are, an alternative which is worth taking seriously for those after heating their homes with less costs than using classic fuels, such as gas and wood. We will now take a look at how to make wood pellets so that your investment is complete. However enterprising you may be, you will still have to turn to technology which involves, for a full line of production, a grinder, a dryer, a mixer and the pellet mill or press.

Making pellets also implies a series of steps, which range from preparing the gross material for the pellet mill or a press and their production. These steps are chipping or shredding the raw materials until the pieces are no larger than 2.5 cm, grinding, drying, refining and stocking the gross material, producing the pellets, cooling them and finally packing them.

The first stage is grinding the raw material, usually wood waste. The grinder is equipped with feeding rolls which can be controlled in both directions so the material is broken into small pieces. In the next stage, the dryers dry the grinded material so that the content moisture should be 10 to 20 percent. The device dries the raw material in a few minutes, preparing it for the final stage.

The mills or the presses can also be used in households, farms and small production units to granulate cattle fodder or to recycle various raw materials and turn them into pellets which boast a caloric power superior to the raw material’s. If used with grinders and dryers, then you have the whole production line. The mills/presses feature a die and roller. The die is a metal piece with holes drilled through it. The roller goes across the die and presses the wood through the holes into pieces the size of finished pellets. Pellet presses are flat die or round die. Either types can be used to make wood pellets that are consistent in density and moisture level.

You can rely solely on the press if you can cover the initial two steps by own resources, but the process of chipping/shredding the wood and then drying the war material is a time and effort consuming. The price for such a whole production line starts at about 20,000 Euros and can go as up as 120,000 Euros. A press alone sells from 3,000 Euros, depending on the engine capacity.
