What is a screw bio briquettes machine

Screw bio briquettes machine is a kind of briquette machine used to briquette biomass materials with stick shape. As the briquette is usually used to make charcoal, so it also has another common name charcoal briquette machine.

Material

Following are some of the materials can be used in screw briquetting machine:

  • Sawdust
  • Wood shaving
  • Branch
  • Peanut shell
  • Corn stalks
  • Bamboo dust
  • Bagasse residue
  • Coconut shell
  • Coffee husk
  • Cotton stalk
  • Tobacco waste
  • Jute waste

How the briquette is made

For answering this question, first let’s find the structure of the screw bio briquettes machine below:

1. Charging hopper 2. Heating rings 3. Shaping drum 4. Screw Shaft 5,9. Oil seal 6,7,8. Bearing 10. Spindle 11.Electric control board 12. Motor 13. Sensor

The working process is as follow:

The whole briquette process is to compress the raw material under high pressure and high temperature. The machine uses a large screw to grind, compress and extrude the biomass into briquettes. The self bonding of biomass to form a briquette involves the thermo-plastic flow of the biomass. The natural lignin content in biomass is liberated under high pressure and temperature(200-300°C). Lignin serves as the glue in the briquette process, binds the particles of biomass together, thus binding, compressing the biomass to form into high density briquettes.

A briquette process without binder

The briquette is much pure, clean and green fuel as we use the natural lignin to make the briquette without any other materials.

Requirement for raw materials.

  1. Size: less than 5mm;
  2. Moisture: 6-12%; If the moisture is less than 6%, the briquette will with lower strength as the viscosity and the conversion of raw materials is in low level. Besides, if the moisture is more than 12%, the briquette will be soft and always with crackles, also with a low density.

Final product

product from screw briquetting machine

Size: Diameter 45-80 mm; Inner hole 15-20 mm; Length 200-500 mm;

Shape: Square, hexagonal, pentagon, pentagon with edge, hexagon with edge, etc.

Density: 1.2-1.4 kg/m³;

Usage of the final briquette

The briquette can be used as fuel for burning, and because of the hollow shape as well as the high density, it is an ideal product for making charcoal.

Reference Specifications of charcoal made by briquette with screw briquetting machine:

carbon content> 85%, the calorific value> 4000-7000 kCal, ash <5%, volatile matter <15%, moisture <4%, no impurities, smokeless and odorless, burning time> 3 hours. Density 3 times compare to traditional charcoal.

Crush-Drying-Briquette

It’s easy to run a briquette plant with screw briquetting machine and always with low cost. Normally the briquette line will be with these kinds of machines:

1. Crusher: A crusher will help you to reduce the size of your raw material to proper size (normally less than 5 mm).

2. Dryer: For small capacity drying, you can choose the air flow dryer with small investment as well, if your capacity is bigger, a rotary dryer will be a better choice.

3. Briquette machine: This is how you make the raw material into briquette.

4. Other accessories: Conveyor, material distributor, etc.

An ideal product as raw material for charcoal making

As the high density and the hollow shape, the briquette becomes an ideal material to make charcoal, the high density ensures a long burning time, and the hollow shape makes it easy to turn into charcoal, which not only helps you to save time as well as the energy cost on the charcoal making process.

If you want to make the charcoal with briquette, you can choose our carbonization furnace for further producing.
