sawdust briquette machine/ coal briquette machine/ coal briquetting machine
Brief introduction:
1. It uses the principle of spiral extrusion, compressed the prepared pulverized coal
into a certain intensity of cylinder or plum-flower shaped through extruding.
2. It is the main equipment in the system of molding fuel, it squeeze powder coal into
a certain hardness coal briquette sticks of various shapes according to customer's
requires, in place of block coal, it can make full use of coal dust to reduce fuel cost.

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.
The lignin content that occurs naturally in biomass is liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process, thus binding, compressing the biomass to form intohigh density briquettes. During this process,no binder needs to be used. So the outputting briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires.
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.

Questions:
1. What is capacity of your machine?
--- One inner pot can load 2.5tons machine-made briquettes, 8hours will get one ton machine-made charcoal.
one Inner pot can load 2tons natural wood, 8-10hours will get 600kg-800kg natural charcoal.
Therefore, one furnace can get: 3tons machine-made charcoal, 1.8-2.5tons natural wood charcoal.
2. What is carbonization time?
--- Normally, 8-10hours. If your natural wood is fresh, it takes long time to remove moisture of wood, therefore, carbonization time is longer.
3. When the charcoal is finished?
--- There is no smoke and smoke is blue lucid,the process is finished.
4. How many times should we cool the cahrcoal?
It takes 10-16hours. When the inner pot goes down to 50℃ or less, charcoal can be packaging and collecting.
