Low Cost Wood Chips Sawdust Briquette Making Machine Briquette Extruder

Malaysia Kenya Hot Sale Briquette Machine to make fire wood sawdust biomass briquettes

Raw Material → Crusher → Dryer → Briquette machine→Carbonization Furnace.

The whole charcoal production line mainly includes four needed machines: crusher, dryer, briquette making machineand carbonization furnace.

1. Crusher:

Crusher is to reduce the size of raw materials at 3-5mm, which is suitable for making the briquette.

This crusher can crush: small tree branch, cotton stalks, tree bark, coconut shell, rice straw wheat straw, corn straw, grass river reeds, palm husk, soybean stalk or husk, coffee husk, paddy straw, sunflowers stalk, bamboo and many other agrowastes etc. And the whole production line can help you make the materials into the excellent wood fibers, flour and sawdust directly, save energy and high efficiency. So the invested cost of the charcoal making can be zero.

 2. Dryer:

Air current type dryer is to control the moisture content of raw materials at 8-12%, suitable for making briquette. Too dry or too wet will make the briquette loose, can’t have high density. It is professionally designed for drying different kinds of wood sawdust.

The whole system consists of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock. In this sawdust dryer machine system, wet material is input into hopper by screw feeder. Fuel furnace

produces large volume of hot air. The hot air is driven into steel pipes, mixed with wet sawdust and moved through curving pipes and drying chamber by the power of fan blower.

Fast moving hot air sustains and is mixed with raw material sent by spiral feeder in the suspending state through the steel pipe; moisture evaporates as the material traverses along the steel pipe and is rendered dry at the discharge end. Humid air is continuously exhausted, thus the material is dried.

3. Briquette making machine:

Briquetting is a process during which raw materials are compressed under high pressure and high temperature. After the processing of drying and pressing, the briquette is characterized by high density, small in size, better combustion, capable as the substitute for the superior coal or firewood.

This bio-fuel briquette is 45-80mm in diameter, occurs in the hollow quadrangular or hexagonal cylinder or hollow hexagonal with a 15-20mm hole through the body.

• The available shape: square, hexagonal, pentagon, pentagon with edge, hexagon with edge
•  The available diameter could be: 50mm,.60mm,.70mm.80mm and so on
• The available length could be :20cm,30cm, 40cm, 50cm
• The feature of the final product : Specific gravity: 1300—1900kg/m   Calorific value: 4500—5000kcal/kg

Technical Parameter: 

4. Carbonization furnace:

Carbonization furnace is to carbonize the biomass briquette into wood charcoal.

Carbonization furnace for biomass charcoal can greatly increased carbonizing ratio (increased from about 88% to 99%) and shortened the carbonizing time (from 24 hours to 6 hours), and shows the features of easy operation, higher safety, high efficiency, and energy saving. This furnace is ideal equipment for wood briquettes to have anoxic distillation carbonization.

After carbonizing, the electrical conductivity and thermal conductivity will be enhanced; the graphite structure increased, fixed carbon content increased, calorificvalue higher, ash content lower, volatile

material reduced, density higher, more solid etc.
