Nowadays, following industry and technology development, environment is a big problem, especially industrial waste water. Water purification is becoming more and more important and popular. There are so many kinds of raw materials to make water purification products, and coal powder and carbon black powder are common. The water purification industry is also looking for ways to reduce production costs. The final products processed from coal powder can be used as water purification materials and as fuel for stoves.
Our coal pellet machine for water purification can meet these requirements and can also process carbon black powder. Coal powder pellet machine is used to press different powders below 3 mm into pellets. The coal pellet making machine can process coal dust, coke powder, charcoal powder, carbon black powder, and other mineral powders into cylindrical pellets. This flat die coal pellet mill for water treatment ensures smooth, dense, and uniform pellets suitable for water purification and fuel applications.


How the Coal Pellet Machine Works: High-Pressure Extrusion and Friction
The Pelleting Process & Moisture Requirements
The secret of our flat die coal pellet mill is in high-pressure extrusion and friction between the rollers and the die. During the pelleting process, the powdered coal is first mixed with a binder, such as starch, and stirred evenly. To achieve optimal pelletizing results, the moisture content of the coal powder must be strictly controlled at 8%-12%, and the binder (such as starch or coal tar) addition ratio is generally maintained at 3%-5%.
Extrusion Friction & Mechanical Hardness
Then the mixture enters the pelleting chamber. The rollers apply instantaneous high pressure while friction generates heat, compacting the powder into dense, smooth, and bright pellets. This process allows direct pelleting and ensures high-quality 5 mm coal pellets for water purification. The final extruded cylindrical pellets boast a mechanical hardness of over 95%, ensuring they maintain their structural integrity and will not easily dissolve or turn to sludge during long-term water immersion.
