Coal Ball Press Machine

Coal Ball Press Machine is mainly used for pressing materials with low water content such as all kinds of coal briquette, ore powder and refractory. Dongfang Machinery coal briquette ore powder ball press machine is a new type of briquette machine with high efficiency, energy conservancy and environment protection. Materials after being briquetted by coal briquetting machine is smaller, energy saving, environmental friendly, easy to transport and improved in wastes recycling rate, which make it have good economic and social benefit.

Coal Ball Press Machine

Application of Coal Ball Press Machine

Coal briquetting machine can be used to press all kinds of powdery materials like coal power, iron powder, coking coal, aluminum powder, iron slag, oxide scale, carbon powder, slag, gypsum, tailings, sludge, kaolin, clay, activated carbon, coke and waste residue in refractory, power plant, metallurgy, chemistry, energy, transportation, heating and other industries.


Structural Features of Coal Ball Press Machine

The performance of the coal briquetting machine is mainly determined by the roller skin of the main engine. This type of coal briquette machine is casted with 65 manganese, and with special heat treatment, its hardness can reach over 58 degree. The roller skin adopts composite assembly, so that it can be changed when abraded. This briquette machine has a shock absorber which can better protect the equipment from the impact of hard materials. The briquette machine is designed with ball bowl adjustable device to make sure the ball bowls of the two rollers are always in the adjustable range.

Working Principle of Coal Ball Press Machine

Host gets power from the electromagnetic adjustable speed motor, and drives the driving shaft rotating by a reducer. The driving shaft and driven shaft keep synchronization operation. After the pressed material enter the feeding mouth, it is pressed into ball under great pressure. At the back of ball press machine, the hydraulic devices are installed, and it can protect the ball press machine from damaging when super hard material enters it.


Process FLow of Coal Briquetting Plant

1. Get raw material prepared: sieving, pulverizing the charcoal lumps/chunks or coal mateirals into fine powder.

2. Get appropriate binder.

3. Mixing process: mixing coal / charcoal powder with binders and some other additives if needed.

4. Briquetting process/Extruding process: briquetting/extruding mixed charcoal powder into specific shape with charcoal making machine.

5. Drying process: sun drying or automated tunnel type continuous drying

6. Packing process: carton packing, gunny packing, paper packing.
