Sawdust, also known as wood shavings, is a common by-product of woodworking operations such as sanding, milling, sawing, planing, and routing. However, with proper recycling, the value of this waste material can be significantly increased. One effective way to achieve this is by converting sawdust into sawdust charcoal using a sawdust charcoal machine. This machine carbonizes or heats the sawdust under high temperatures in an oxygen-free environment. Despite the term "sawdust" in its name, this machine can process various types of biomass, including coconut shells, palm shells, rice husks, sewage sludge, and municipal solid waste.

In addition to sawdust charcoal, this process also produces other valuable by-products like biogas, tar, and wood vinegar. The benefits of investing in a sawdust charcoal making machine are substantial, and there is much to gain from using this machine. If you're considering purchasing Beston sawdust charcoal making machine, you may wonder how it works and what the applications of its end products are. This post aims to address those questions.

The Sawdust Charcoal Making Process

The entire process of making charcoal from sawdust usually takes 15 to 20 minutes. It's important to note that the raw materials fed into the machine should have a size smaller than 50mm and contain less than 20% moisture. A specific shredder is used to crush the sawdust or other biomass materials to meet these requirements. The crushed materials are then sent to the drying system through a quantitative feeder.

Once the drying process is completed, the dry sawdust is transferred to the carbonization furnace. At a temperature of approximately 350 degrees Celsius, sawdust charcoal is produced and subsequently delivered to the cooling system for discharge.

Throughout the carbonization process, combustible gas is generated. This gas passes through a cyclone dust remover and spray washer for cleaning before moving on to the condenser. The condenser separates and collects wood vinegar and tar.

The combustible gas is then directed to the carbonization reactor, where it is used for heating purposes.

Applications of the Final Products

i) Sawdust charcoal:

The charcoal produced serves various purposes in daily life, such as fuel for BBQ, cooking, and heating. It is also widely used as a fuel source in industries. In agriculture, sawdust charcoal is utilized to improve soil quality through long-term adsorption of heavy metal pollutants. Additionally, it can be used to manufacture clay construction bricks.

ii) Biogas:

Biogas has diverse applications, including use as a fuel for cooking, greenhouse agriculture heating, and electricity generation. It is also used within the sawdust charcoal making equipment for heating and drying purposes.

iii) Tar and Wood Vinegar:

These products are commonly employed as raw materials in chemical and medicinal product manufacturing. They are also used in the paint and shipbuilding industries.

In conclusion, a sawdust charcoal machine offers numerous uses for its end products. From producing sawdust charcoal as a versatile and efficient fuel source to generating biogas for various applications, and obtaining tar and wood vinegar for industrial purposes, this machine provides an effective solution for recycling and utilizing biomass waste. Investing in a sawdust charcoal machine can bring significant benefits both economically and environmentally.
