Coal/charcoal briquette extruder is also called screw type briquette press, which can not only process various kinds of charcoal materials, like wood charcoal, coconut charcoal, carbon blacks, also can process other materials, coal, coke, etc. The advantages of the this extruding machine are high forming ratio, easy operation and maintenance, low cost and so on. The finished products are used in BBQ, coal gas industry, fertilizer filed, etc. The cross-section shape of the finished briquettes produced by this extruder can be designed and produced according to customers' requirements, like square, triangle, hexagonal, stars, etc. 

Working principle: 
The electric motor transfers the power to the gear reducer through the V-belt, and the gear reducer continue to transfer the power to the driving shaft by coupling, finally the screw propeller in the driving shaft pushes the materials inside the molding part and get the briquette bars come out.  
Features: 
1. The finished briquettes are with high density and good briquetting ratio, easy for transportation and storage. 
2. The maintenance of this extruder is easy and few cost. 
3. This charcoal extruder is also one kind of shisha charcoal making machine, it can make silver charcoal and cube charcoal. 
4. The automatic cutting system is equipped in the extruder, which solved the problem of manual cutting work and increase the working efficiency.
