Charcoal Briquette Production Line

Charcoal briquette has the advantages of high density, small volume, good flammability, smoke-free, tasteless, non-toxic, etc. It’s widely used in heating, BBQ market. In the industrial area, it’s the alternative raw material of coal or heavy oil. 

Many materials suitable to make the charcoal briquette, if the wood logs are available, they are very suitable to make the charcoal briquette directly. But since the forest resources are limited, and also this will add the cost, so more wood waste, branches, sawdust, agro waste become alternative raw materials. But these materials need some special process before they become charcoal briquette. 

3.1Crushing the material into granules less than 10mm. Below are the crushing machine for wood logs, branches, straws, agro waste.
 

3.2 Dry the granules to reduce the moisture between 8%-12%,this process needs special attention. Below are the 2 styles dryers for different capacities.
The airflow dryer usually match small capacity production line, for large capacity line, it can't reduce too much moisture. Rotary dryer is very suitable for large capacity line, and for the material with above 30% or 40% moisture. Because its effect of removing moisture is obvious.
 

3.3 Forming the raw materials into hexagonal shape through the high temp and pressure stick machine. We have machines with different yields as the below chart:

Model	Motor Power(KW)	Weight(KG)	Packing Dimensions(MM)	Capacity(KG/H)
50	15	600	1500*600*1600	160-200
50-new	18.5	700	1600*600*1700	250-300
70/80	18.5	750	1850*650*1300	350-400
140	7.5	700	2000*1000*1100	380-400
180	18.5-22	1200	2400*1200*900	800-100

 3.4 Carbonizing the sawdust stick into charcoal briquettes. This process will heat and burn the stick in the carbonization furnace, in order to save cost, some customers will build the carbonization furnace by themselves. 
 
3.5 Cooling the sawdust stick to room temp.
Since the temperature of charcoal briquettes is very high, the charcoal briquette needs cooling for 8-24 hours.
