Screw Conveyor or Auger:

  • In screw press briquette machines, a screw conveyor or auger transports the raw biomass from the hopper to the compression chamber.
  • It helps in evenly distributing the material and ensures a continuous flow.

Compression Chamber:

  • This is the heart of the briquetting machine, where the actual briquetting process takes place.
  • The chamber contains the necessary mechanisms to compress the biomass materials under high pressure.

Die or Mold:

  • The die or mold is a critical component within the compression chamber.
  • It defines the shape and size of the briquette.
  • Different dies can be used to produce briquettes of various shapes and sizes.

Rams or Pistons:

  • In piston press and hydraulic briquette machines, rams or pistons apply pressure to the biomass material within the compression chamber.
  • They are responsible for compressing the material into briquettes.

Briquette Ejection System:

  • After the briquettes are formed, there needs to be a mechanism to eject them from the compression chamber.
  • This can be a simple hydraulic cylinder or a mechanical system, depending on the machine type.

Pressure Gauge

  • Many briquetting machines are equipped with pressure gauges or sensors to monitor and control the pressure applied during the briquetting process.
  • This helps ensure consistent briquette quality.

Drive System

  • The drive system provides the power needed to operate the machine.
  • It can be electric, hydraulic, or mechanical, depending on the machine type and size.

Control Panel:

  • Modern briquetting machines often have a control panel that allows operators to set and adjust various parameters, such as pressure, temperature, and production speed.

Cooling System:

  • Some machines include a cooling system to cool down the newly formed briquettes as they exit the compression chamber.
  • This helps solidify the briquettes and prevent them from sticking together.

Safety Features:

  • Safety features like emergency stop buttons and protective guards are essential components to ensure the safe operation of the machine.

Frame and Structure:

  • The frame and structure of the machine provide stability and support for all the other components.
