Charcoal briquette is made of carbonized biomass powder which combined with other adhesives, and then the mixture is pressed by the briquette machines.

Its raw materials sources are various, like crop straw husk, peanut shell, cotton shell, corn cob, rice husks, and other forestry residues which can be used for briquettes.

There are many types of briquette machines that can be used for charcoal briquetting on the market. Users can choose a suitable one according to their own production requirements, shape and size, quality requirements and the use of binders.

According to the different devices they are equipped, there are mainly 5 types of machines for briquetting.

1. Strong pressure briquette machine
The high-pressure briquetting press uses two opposing moving rolls to press the dry powder into different shapes which can be square, egg, oval, pincushion shape and the like. The size of the briquette is 20-75 mm.
Production capacity: 1-8.5 t/h
Finished product shape: Round, pillow, oval, square, etc.
Applied materials: Charcoal powder, aluminum powder, activated carbon, clay, coke breeze, coal, cryolite, fertilizers, plastics, limestone, etc.

2. Hydraulic briquetting machine
The entire hydraulic system ensures the molding pressure, and the system is reliable and easy to operate. In addition, it also acts as hydraulic protection to adjust the roller pressure.
Production capacity: 4-18 t/h, 25-70 t/h
Finished product shape: Round, pillow, oval, square, etc.
Applied materials: coal powder, charcoal, wood charcoal, coconut charcoal, coal slime, coke powder, ore powder, gypsum, quicklime, mineral powder, etc.

3. Static pressure briquette making machine
The static pressure briquetting machine is used to press the wet powder, that is, a certain proportion of water and other liquid binders are added to press the ball.
Production capacity: 2.2-40 t/h
Finished product shape: Round, pillow, oval, square, etc.
Applied materials: Charcoal and coal powder, coal slime, coke powder, ore powder, gypsum, quicklime, mineral powder, etc.

4. Dry powder briquette machine
The dry powder briquette machine has a cushioning device to better protect the equipment from hard objects. It is designed with an adjustable device so that the mould is always within the adjustable range without displacement.
Production capacity: 0.5-15 t/h
Finished product shape: Round, pillow, oval, square, etc.
Applied materials: Coke powder, graphite powder, fly ash, oxide, vanadium and titanium ore powder, steel refining agent, manganese, iron powder, blue carbon dust, lime powder, magnesium oxide powder, etc.

5. Twin-Roller briquette machine
Production capacity: 1-30 t/h
Finished product shape: Round, pillow, oval, square, etc.
Applied materials: Graphite powder, steel refining agent, manganese, ceramics, refractories, etc.
