what is briquetting machine

A briquetting machine, also called briquette press, is a kind of industrial forming machinery that compresses loose powdery raw materials into compact solid briquettes under mechanical, screw or hydraulic pressure.

Loose powder such as coal dust and charcoal dust is scattered, difficult to transport and inconvenient for direct combustion. With the briquetting machine, these materials are shaped into regular solid blocks. This greatly improves raw material utilization, facilitates storage and transportation, and upgrades the commercial value of waste powder materials.

Although different models have different structures, the core principle stays consistent.

Raw powdery materials are fed into the molding chamber. Under continuous pressure, the gaps between powder particles are squeezed out. Loose powder is tightly combined and shaped into standardized briquettes. After molding, finished briquettes are discharged automatically.

Different machine types adopt different pressure methods:

Adopts twin roller extrusion structure. Suitable for mass production of coal powder, coke powder and mineral powder. It can produce pillow-shaped, round coal briquettes, widely used in large-scale coal briquette production lines.

Rely on powerful hydraulic pressure to produce high-density charcoal blocks. Finished briquettes feature high hardness, low breakage rate, ideal for high-grade BBQ charcoal for export.

Specialized equipment for cylindrical charcoal sticks. Simple operation, cost-effective for small and medium charcoal processing factories.

Our briquetting machines are mainly designed for carbon-based powder materials:

Coal dust, slack coal, lignite powder, charcoal dust, bamboo charcoal powder, coconut shell charcoal powder, coke powder and other mineral powder.

✅ Convert waste powder into marketable solid fuel

✅ Reduce dust pollution and raw material waste
