Honeycomb coal briquette machine is to regard the well-processed coal dust as raw material, after crush, mix, and then compress to coal briquettes. This good quality iron raw coal charcoal honeycomb briquette machine uses iron powder charcoal/raw coal charcoal as raw materials. But, at first, the raw materials should be crushed into small pieces (the diameter < 1 mm). And this machine has a large capacity, so it is high efficiency. The holes on the surface of the coal briquette make them can be easily and completely burned, reducing energy waste. At the same time, this machine owns a lot of molds, and you can change the molds easily per your special needs. After many improvements, our honeycomb coal machine has the advantages of reasonable structure, high finished product density, superior performance and long service life. https://www.charcoal-machines.com/coal-an , d-charcoal-extruder-machine.html
