A small charcoal-making machine usually consists of a crusher, dryer, carbonization furnace, briquette machine, and a set of production lines. The production lines have biaxial points and spiral feeding systems to ensure that you don’t need to manually pour the ingredients into the crusher.
Production process
There are four steps to using the small charcoal making machine: crushing, drying, making briquettes of charcoal, and carbonization. The machine uses a combination of various ingredients, such as bamboo dust, bamboo chips, shavings, peanut shells, rice husks, sawdust, and wood chips. It grinds these ingredients into a fine powder and then applies high pressure to produce charcoal briquettes. Here’s the step-by-step process of making charcoal in this machine:
1. Crushing – In this step, the crusher breaks down the above-mentioned ingredients into small pellets. The pellets then go through another chamber whether they are grounded properly before sending to the drying chamber.
2. Drying – Drying is a crucial part of making charcoal since even the smallest percentage of moisture may affect the quality of the final products. The pellets go into the drying chamber where the high temperature eliminates moisture from the mixture.
3. Shaping – Once the machine gets rid of the moisture in the ingredients, it sends the powder into the briquette machine to give shape to the charcoal. You will notice the briquette machine making bar-shaped charcoal within a few minutes.
4. Carbonizing – The charcoal maker for sale cools the charcoal briquettes down. Cooling is essential to ensure that the charcoal burns quickly when you light a briquette.
Working principle of a small charcoal-making machine
A small charcoal-making machine consists of a molding cylinder with a heating ring. The cylinder first heats up to as much as 350℃ before going through its spiral extrusion molding. An advantage of using a small machine is that it can utilize rice husk, sawdust, and even straw to make charcoal. The machine presses these ingredients and grinds them properly to produce charcoal.
Most ingredients usually contain at least 6 to 12% moisture before they go into the drying chamber. The drying chamber meets the temperature requirements of the machine to ensure that it produces high-quality charcoal within a few minutes.

Carbonization of charcoal
The carbonization of charcoal involves two stages: pre-carbonization and carbonization. Drying the ingredients is a part of the pre-carbonization stage. Here, the machine’s interior temperature may go up to 150℃, thus providing a slow pyrolysis rate. The external heat supply quickly evaporates the moisture in the wood and bamboo chips.
In the next stage, the biochar equipment for sale performs thermal decomposition by increasing the temperature to a maximum of 275℃. A hammer mill simultaneously keeps breaking the raw materials and ensures that they meet the size requirements of the briquettes in the next stage. The briquette then finally gives shape to the charcoal before sending it out from the exit chamber.
Small charcoal-making machines are available in various types, such as roller, piston, hydraulic, and screw. Buy one that fits your budget and the amount of charcoal you plan to manufacture every day.
