What machine is used to make briquettes?

The machine commonly used to make briquettes is called a briquette press or briquetting machine. There are various types of briquette presses available, but they all work on the same principle of compressing biomass or other materials into compact, solid briquettes.

Briquetting machines typically consist of a hopper, a screw or piston-based system for feeding the material into a compression chamber, and a mold or die that shapes the material into briquettes. The material, often biomass such as sawdust, wood chips, or agricultural residues, is fed into the machine, compressed under high pressure, and then extruded through the die to form briquettes of a specific shape and size.

The briquetting process usually involves the use of binders or additives to help hold the briquettes together. These binders can be natural substances like starch or lignin, or synthetic binders depending on the specific application and requirements.

Briquettes produced by briquetting machines have various applications, including as a fuel source for heating or cooking, as a substitute for traditional charcoal or coal, and in industrial processes where a compact and energy-dense fuel is needed.
