How To Make Wood Pellets from Sawdust : A Step-By-Step Guide

In this guide, you will learn how to make wood pellets from sawdust. It is a step by step guide that will walk you through the process and show you exactly how to make wood pellets from sawdust at home.

Wood pellets are a great way to reduce your carbon footprint, but heating your home or commercial space with them can be a hassle. This is especially true if you have to keep buying pellets to burn.

Making your own pellets may sound like a bit of a daunting task at first, the good news is that there are ways to make your own pellets. If you already have a wood pellet stove but don’t feel like buying wood pellets constantly, make your own pellets can be a great way to save money and reduce the amount of waste your facility creates.

What are sawdust pellets?

Before we go any further, let’s get this question out of the way—what are sawdust pellets?

Sawdust pellets, also known as wood pellets and biomass pellets, are made from sawdust, a byproduct of the lumber industry. Sawdust can be made from pine, fir, birch, poplar and fruit woods as well as crop straws. Sawdust pellets are used for burning, barbecue and furnace fuel; they’re also applied in industrial boilers and electricity generation plants.

The Benefits Of Sawdust Pellets

Sawdust pellets were once considered a waste product that was thrown away by the lumber industry. Now this waste product is being transformed into a valuable resource that can be used as an alternative to fossil fuels such as coal or oil. Sawdust pellets are made from sawmills that process trees into lumber products such as furniture, flooring and cabinets. These mills normally have large quantities of sawdust left over after processing wood into lumber products and they need to find somewhere to dispose of this leftover material.

The benefits of using sawdust pellets include:

  • They produce little ash when burned which means less pollution in the air;
  • They have a high calorific value which means they produce more heat per unit than other types of biomass;
  • They have low moisture content which makes them easy to store and transport;

The Basics of How to Make Wood Pellets From Sawdust

Step 1—Pre-treat Your Sawdust

To make wood pellets from sawdust, it is necessary to use sawdust of uniform standard, which means that the size is uniform at 3-5mm and the humidity is 8-12%. If your sawdust do not meet this standard, you need to pre-treat your sawdust raw materials. If your sawdust too large in size, you will need to use a hammer mill to reduce the size. If your sawdust has a high moisture content, you will need to use a dryer to dry them first .Until the sawdust meet the requirements, you can proceed to the next step

Step 2—Compress Your Sawdust into Wood Pellets with a Pellet Machine

Now that you have ready sawdust, it’s time to start making pellet. The process is simple: You feed the sawdust into the hopper, and then push it through the pellet mill. The pellet mill will press the sawdust in the pelletizing room, the sawdust will be shaped into pellets by continuous pressing process. Then the pellets will pressed out from the pellet machine die.

Pellet mills can be divided into industrial wood pellet mill and homemade pellet mill, depending on their usage scenarios. Industrial wood pellet mill has relatively large outputs and high power. Their outputs range from 1 ton per hour to over 100 tons per hour, and their power ranges from 90kW to 1500 kW. Homemade pellet mills are relatively small but still have significant outputs, ranging from 100 kg per hour to 500 kg per hour. Their power ranges from 1.5 kW to 15 kW. You can choose the appropriate model according to your needs and budget.

Step 3—Pellets Cooling, Packaging and Storage

After you have pressed the sawdust into wood pellets, it is time to cool them down and then package them for storage. The reason for cooling the pellets is to allow them to solidify so that they can be safely stored without degrading in quality or losing any of their fuel value.

Typically, you will want to cool the wood pellets for about 10 minutes before packaging them up so that they do not have any chance of melting or degrading during transport.

If you have access to a large air conditioning unit, this can be used for cooling the pellets. However, if you do not have access to such equipment, you can use simple passive means for cooling your sawdust pellets. This involves placing the container of pellets in an area where there is good air circulation so that heat from them can dissipate into the surrounding air rather than being trapped inside the container itself.

When it comes time to package up your finished sawdust pellets into storage bags or other containers, you’ll want to make sure that they are completely dry first. If they aren’t dry enough when packaged up and stored away, they could start breaking down into smaller pieces over time due to mold growth within them (which could cause them not only to lose their shape but also become less effective as fuel).

Conclusion

Making wood pellets at home can save you a lot of money over time. It’s also a great way for you to reduce waste and recycle, which will help the environment. Plus, it’s not hard to do. Just keep the information from this guide in mind, and you’ll be able to easily producing wood pellets from sawdust on your own.
