Chinese compressed coal production line includes 7 machines: 1- Coal press machine - compressed or extruder that includes anti-wear cylinder with long life and Mardon with long life. 2- Dryer, which includes dryer pipes and drying fan. 3-milling machine 4- Traditional furnaces that include vacuum and choke. 5- sawdust sieve 6- Gas burner or diesel. 7. Cyclone The pressurized charcoal press or extruder is able to produce 150 to 200 kg of raw coal per hour. This production line works with wood waste, which is the same as sawdust and charcoal soil, and because the raw materials of this machine are almost cheap and the product is very high. It is more expensive than raw materials and can be very profitable. Sawdust is used as the main raw material and 30% of charcoal and walnut bark, each of which is found in abundance. Industrial furnace: Due to the non-excretion of tar and charcoal vinegar, charcoal is empty and fragrant and is not economical due to the use of torches and electric lamps, and because the industrial furnace is made of iron, it disappears after one month of oxidation. Traditional furnace: The input capacity is 550 kg due to the fact that the smoke does not burn in the afternoon. Due to the lack of burners and electricity, it is economical to have a 100% guarantee that China is the inventor and user of these furnaces.
