Common Auxiliary Charcoal Making Machine

When it comes to producing charcoal, the briquetting machine is undoubtedly the star of the show. It’s the key equipment that extrudes the raw material, giving you an immediate, satisfying look at the finished product. However, briquetting is just one step in a complete charcoal production line. To successfully manufacture high-quality charcoal briquettes, you also need auxiliary equipment to properly pre-treat your raw materials. In this article, we will guide you through the essential supporting machinery needed to complete your setup

The traditional method of manufacturing raw wood charcoal involves digging an earthen pit, loading it with wood, igniting it, and covering it with soil. The heat generated by burning a portion of the wood is sufficient to carbonize the remainder. Alternatively, an “earth kiln” can be created by covering a wood stack with earth and sod, then lighting it through specialized openings in the cover.

In contrast, modern charcoal production utilizes advanced machinery and equipment. The primary advantages of a contemporary wood carbonization furnace over a traditional earth kiln include:

Simplified Operation: The process is highly user-friendly, allowing even beginners to operate the equipment with ease, whereas traditional kilns require a high level of technical expertise.

Enhanced Efficiency: Modern furnaces drastically shorten the production cycle. While a traditional earth kiln typically requires 5 to 7 days to complete a batch, modern equipment can produce charcoal within a single day—with some compact models finishing a cycle in just a few hours.

There are two types of carbonizer for choice.

This type of carbonization furnace has a variety of specifications, and customers can choose models with different production capacities according to their needs.

If you want small household processing, it is recommended to use a small carbonization furnace. After all, the footprint is relatively small, the volume is also small, and it is simple and convenient to use. The advantage of a horizontal carbonization furnace is that it can recycle and reuse the combustible gas produced.

This type of furnace can carbonize both raw wood materials and machine-made charcoal briquettes.

Its biggest feature is the continuous production of smokeless carbonization throughout the entire process. And a carbonization furnace can have multiple inner tanks. This can lead to multiple carbonizations in one furnace.

After a batch of carbonization is completed, the inner liner can be removed for cooling and the next batch of carbonization can continue. This cycle carbonization saves time. Charcoal production lines or large charcoal plants can consider using the vertical carbonization furnace.

If your end product is not raw lump charcoal, but rather shaped charcoal briquettes, a complete production line will require additional auxiliary machinery.

Carbonized raw materials—such as carbonized logs, branches, coconut shells, and wood waste—are typically too large and irregular in size. To achieve the optimal briquetting and molding effect, these materials must undergo a pretreatment process before entering the briquette machine. Therefore, alongside the carbonization furnace, the following auxiliary machines are essential:

• Charcoal Powder Crusher/Grinder: To pulverize the bulk charcoal into a fine, uniform powder.

• Charcoal Roller Mixer: To thoroughly blend the charcoal powder with binders and water, ensuring a consistent mixture for high-quality molding.

To produce machine-made wood charcoal, the standard process is briquetting first, followed by carbonization.

A sawdust briquette machine is used for this process. Before briquetting can begin, the raw wood materials must first be crushed and dried to the proper moisture level. Once the briquettes are formed, they undergo final carbonization.

Therefore, in addition to the briquetting machine, the essential equipment used in this production line includes a wood crusher, a sawdust dryer, and a carbonization furnace (please see Part 1 for detailed specifications regarding the furnace).

Wood Crusher

The wood crusher is a highly versatile and practical piece of equipment. It handles a wide range of raw materials, including logs, branches, and various wood processing residues. The output size can be adjusted from 3mm to 20mm to meet diverse production requirements. Featuring a compact structure and a small footprint, this machine is exceptionally easy to operate.

Offering a low initial investment paired with high output capacity, it serves as essential preprocessing equipment for charcoal production lines, as well as a valuable asset for various wood processing plants.

Materials such as sawdust, bamboo shavings, wood shavings, particles, rice husks, crushed shavings, branches, and wood chips larger than 5mm must be crushed.

Sawdust Dryer

To produce machine-made wood charcoal, the wood sawdust briquette machine has a requirement for the moisture content of the raw materials, which should be below 12%. If the raw materials are too wet or too dry, the wood briquettes produced will either not be in shape, or the sawdust briquette machine will not produce the wood briquettes.

Another thing is that if your raw materials are not dried, the produced wood charcoal is not easy to ignite and is prone to smoking when ignited.

We know that there are two types of dryers. One is a Drum Dryer, and the other is an Air Flow Dryer. How should we choose?

If the humidity of your raw materials is high, above 50-70%, and the production demand is also high, then you need a drum dryer. If it is a small charcoal production plant or wood pellet factory, it is recommended to use an air flow dryer.

The above are various auxiliary equipment that will be used in different charcoal production lines. Customers can make reasonable choices based on their actual situation.
