Charcoal Ball Press Machine

A charcoal ball press machine is a versatile device designed to compress various powdered materials—such as charcoal dust, coal powder, dry powder, coke powder, carbon powder, iron scale, slag, and iron powder—into spherical shapes of diverse sizes and forms using customizable molds. Its primary applications include fuel production, boiler heating, cooking, barbecuing, and other industrial or household uses. The machine can produce briquettes in various shapes like oval, egg-shaped, pillow-shaped, square, and more, tailored to meet specific demands across different scenarios.

This equipment is widely used in charcoal, coal, and metallurgical industries, functioning as a critical production tool due to its efficiency and adaptability. The final briquettes feature high density, strength, hardness, and overall performance. The main rollers are crafted from hard wear-resistant materials, which not only improve molding quality but also extend the lifespan of the roller dies, ensuring stable and efficient long-term operation.

The machine is mainly composed of key components including a hopper, gears, compressing rollers, conveyor belt, motor, and speed regulator. Its core working mechanism involves two gears driving two opposing roller dies to compress materials into two hemispheres, which are then merged to form a complete spherical shape. This design ensures a compact structure and stable operation, enabling efficient molding of charcoal briquettes.

The raw material of the coal ball press machine ：

1.Coal/charcoal powder/coke.

2.Metal powder: Iron powder, copper powder, magnesium oxide powder, lead, chromium ore,  zinc scrap, bauxite, nonferrous metal powder, silicon manganese alloy powder etc.

3.Mineral powder: toner, aluminum powder, gypsum, sludge, desulphurization gypsum powder etc.

Note: the briquettes shape and size are defined by customers.

a) Particle Size Specifications:

Particles smaller than 1mm: 30-40% proportion.

Particles between 1-2mm: 30-40% proportion.

Maximum particle size ≤3mm, with proportion ≤20%.

b) Moisture Content Requirements:

Material moisture must be maintained at 8-12% to ensure molding efficiency and equipment functionality.

c) Prohibited Materials:

Do NOT mix sieve fragments, hard block debris, or impurities into the material to avoid damaging rollers/main shafts and reducing equipment lifespan.

d) Binder/Additive Guidelines:

Users should prepare suitable binders or additives based on coal type and application environment to guarantee briquette quality and performance.

（1）If your raw materials are sawdust, rice husks, or coconut shells, we recommend processing them into charcoal using our carbonization furnace. This converts organic waste into high-quality charcoal feedstock for subsequent production stages.

（2）The carbonized charcoal is then crushed into fine powder using a grinder. This ensures uniform particle distribution, facilitating efficient mixing and shaping in later steps.

（3）Use a charcoal mixer to thoroughly combine the powdered charcoal with binder. Proper mixing guarantees homogeneous consistency, which directly enhances the strength and integrity of the final briquettes.

（4）Mix starch and water in precise proportions using a stirrer until a lump-free, smooth solution forms. This creates an effective binder solution ready for application.

（5）Finally, our briquette machine compresses the mixed material into customizable shapes based on your specific needs, accommodating diverse industrial or domestic applications.
