In this article we will discuss how wood pellets are made. Pellets can be made from many forms of biomass besides wood including paper, cardboard, grain, straw, corn husks, yard wastes and more. The process for making pellets from all these materials is basically the same but in this article we will focus on making wood pellets. pellets

A pellet is simply material that has been compressed into a pellet form and held together with a binding agent. With some materials the binding agents are naturally occurring but in others they have to be added.

Before wood can be made into a pellet it is broken down into small pieces like sawdust. To do this larger pieces of wood can be run through a chipper. Most chips are still too large so a hammer mill can be used to break them down even more.

The pellets are made by pressing this material into a pellet die. A die is a piece of metal that is full of pellet sized holes. The top of the holes are tapered like a funnel so as the material is pressed deeper into the hole it gets compressed as the hole becomes smaller.

The compression and friction heats the pellet and melts the binding compounds. As soon as the pellets are extruded out of the other side of the die they cool and the binding compounds harden and act like a glue that holds the pellet together.

Some materials like softwood have enough natural lignins in them that work as a binder. But other materials need to have some kind of binder added. These are usually organic materials like vegetable oil, flour and corn starch.

In order for a pellet to form properly the material must be dry but still have some moisture. Depending on the material it should be somewhere between 10 and 20% moisture content. In most cases if the material isn't already air dried to the proper moisture level it will have to be dried in a dryer. Dryers are usually the most electricity demanding and dear the main course of action so a great deal of blow dryers are let go with the mill's individual pellets.

This is the simple breakdown of how wood pellets are made. Generating pellets is a bit like preparing food in this often you will need to research somewhat to have the crooks to appear ideal. Seeing that small pellet mls can be purchased house owners and corporations may make their unique pellets because of their individual heat as well as to offer. pellets
