How does the charcoal briquette machine work?

April 28,2024

Charcoal briquette machine, also known as charcoal ball press machine, is a key equipment for charcoal production. It utilizes the principle of screw extrusion to compress the prepared charcoal powder or coal powder into solid briquettes.

Working Principle

The working principle of the charcoal briquette machine is relatively simple yet highly efficient. Here’s how it works:

1. Raw Material Preparation

Firstly, the raw material needs to be prepared. This usually involves grinding or crushing charcoal or coal into powder with a maximum particle size of less than 3mm.

2. Mixing and Stirring

The powdered raw material is then mixed with a binder and water in a certain proportion. The binder helps to hold the briquettes together, while water improves the binding process. Other additives, such as curing agents, can also be added at this stage.

3. Compression Process

The mixed raw material is fed into the hopper of the charcoal briquette machine. Inside the machine, a rotating screw forces the raw material through a heated chamber. The high pressure and temperature generated by the screw extruder compress the raw material into solid briquettes.

4. Forming and Cooling

As the compressed raw material passes through the die of the machine, it takes on the shape of the die holes and forms into solid briquettes. The briquettes are then discharged from the machine and allowed to cool and solidify.
