Product Details
Ring die type GEMCO supply wood pellet mill is a high-capacity industrial pellet mill designed for the production of pellets from wood and other biomass materials. Gemco supply wood pellet mill is a fully automatic ring die pellet mill with a much larger capacity than the flat die pellet mill, normally 1 -2 ton/h. Therefore, the ring die straw pellet mill has been accepted by the majority of the global wood pellet plants. By connecting several ring die wood pellet mill together, the capacity of a wood pellet plant can reach to 20 ton/h.
| Model | Capacity (kg/h) | Power (kw) | Dimension (mm) | Weight (kg) |
| BPM250 | 200~300 | 0.75 | 1700*1200*1000 | 800 |
| BPM350 | 500-800 | 30*2+0.75+0.75 | 2150*1950*1900 | 2200 |
| BPM420 | 1000-1500 | 90+1.5+3 | 2600*1000*2000 | 3400 |
| BPM508 | 1500-2000 | 132+1.5+3 | 2990*1200*2410 | 4500 |
The “ring die” in a GEMCO supply wood pellet mill is the first and the most important part you shall exam while buying a pellet mill. For a wood pellet plant running 10 hours a day, the ring die is the most worn part because it finishes most of jobs of a wood pellet mill. Which means a quality wood industrial pellet mill comes with a quality ring die. The “die” is a metal with multiple holes on it, and during the process, the raw materials are heavily pressed to pass through the holes so that it can be pelletized.
The electrical machine drive the main shaft via reduction gearbox, the main shaft drives the rollers, the rollers rotate around the main shaft and also spin on their axes.
The biomass raw materials will be fed in the feed chamber manually. Under the influence of the material distributor and scraper, the biomass materials will be spread on the flat die evenly. The rollers keep pressing the biomass materials continuously, then the materials will be pressed into the die holes. Finally, the materials will be extruded out as the uniformed biomass pellet.
Force feeding system: the ring die straw pellet mill has a much larger production capacity than the flat die pellet mill, the manual feeding system is no longer suitable for a large scale pellet production. Therefore, ring die straw pellet mill mainly adopts the spiral conveyor to feed the biomass materials into the press chamber.
Suitable electrical machine: the forming of biomass pellet is more difficult than the forming of feed pellet. The moisture content of the biomass materials before pelletizing must be controlled between 13% – 18%. The ring die straw pellet mill has a much faster rotary speed than the flat die pellet mill, so during the pelletizing process, the rotary speed of the ring die must be controlled. There must be a proper time for the biomass material to stay in the holes of the ring die to complete its forming need. During the pressing, the pressure is between 50 -100MPa, and that is why we need the high torsion low rotational speed electrical machine. Most of the ring die straw pellet mill use thegrades 8 electrical machine, the rotate speed is about 750r/min, when the torsion enhanced, the rotate speed is about 141r/min.
High quality forging parts: all the shaft parts of GEMCO ring die industrial pellet mill are made by the high quality forgings, which will definitely add the serve life of the ring die pellet mill.
The size of wood pellet making pellets has various choices: 4, 6, 8, 10, 12mm, or other customized diameter. At the same time, you can customize the ring die of the industrial pellet mill with different thickness and compression ratio to adapt to different materials and realize best pelleting result.
