How to Make Wood Pellets at Home: Easy Step-by-Step Guide

Making wood pellets at home saves energy, money, and helps the environment. In this article, we’ll show you how to make sawdust pellets, list the tools you'll need, walk you through the process, and answer common questions to get you started quickly.

Why Do You Want to Make Wood Chips at Home?

Making wood pellets at home can help reduce energy bills, improve heating efficiency, and provide reliable energy for your home. Wood pellets are a greener fuel, burning cleaner and more efficient than traditional wood or coal.

The biggest benefit of making sawdust pellets at home is cost savings. It also reduces dependence on external energy sources. However, there are a few points to note: 

• Space Requirements：The machine and raw material storage take up considerable space
• Equipment Investment ：The pellet machine requires a significant initial investment
• Noise Problem：Sawdust particle machine in the running process will produce a larger noise 

Raw Materials and Tools to Be Prepared

We’ll explain the materials and tools you need, how they work, and how to use them. This will help you get started fast.

Raw Materials for Wood Pellets Production: 

Sawdust particles are mainly made of wood waste such as sawdust, sawdust fragments and sawdust powder. Other common raw materials include straw, lawn waste and other biomass materials. 

Device Need to Be Prepared:

Specific operating steps for wood chips 

Step 1: Prepare Raw Materials

Raw materials like wood chips need to be cut to a size of 2-5 mm. You can do this at home using an axe or chain saw. You also can opt to buy pre-crushed raw materials or invest in a wood shredder to break down large pieces into smaller ones.

Step 2: Dry the Raw Materials

The moisture content of the raw materials is critical for pellet quality. Ideal moisture levels should range between 10-15%. You can dry the sawdust using specialized equipment or by spreading it evenly in the sun.

Step 3: Prepare the Pellet Machine

Place the dried sawdust or other raw materials into the pellet machine's feed port. Depending on the machine model, you may need to adjust pressure and temperature settings for optimal pellet production.

Step 4: Compress the Raw Material into Pellets

Start the pellet machine. The raw material is compressed under high pressure to form pellets. You can adjust the pellet size by changing the settings.

Step 5: Cool and Screen the Pellets

After forming, cool the pellets to keep their shape during storage. Then, screen them to remove any unqualified particles and ensure consistent size.

Important Notes:

Proper Moisture Content: If the sawdust is too wet, the pellet machine may struggle to compress it effectively. 

Regular Cleaning: Clean the pellet machine regularly to remove accumulated residues and extend the life of your equipment.

Safety Precautions: Wear gloves and safety glasses while operating the pellet machine to prevent injury.

Frequently Asked Questions (FAQ)

What is the best way to store wood pellets?

Store wood pellets in a dry, ventilated area. Use waterproof bags or sealed containers and keep them off the ground to prevent moisture and mold.

Do homemade pellets provide enough heat?

Yes, with the right raw materials and process, homemade pellets typically have a calorific value of 4500-5000 kcal/kg, making them ideal for heating and fuel.

What type of wood is best for raw materials?

Hardwoods like oak, maple, and walnut are best due to their high density and calorific value. Softwoods like pine and fir are also good but have slightly lower calorific value.

Is it expensive to produce pellets at home?

The initial equipment cost may be high, but once you have the equipment, the main cost comes from raw materials like sawdust. If you have access to cheap or free sawdust, production costs are low.

Are homemade pellets legal?

In most places, homemade pellets are legal if they comply with safety and environmental regulations. Ensure the pellet machine you buy meets local laws and is safe to operate.
