A Dual Track Ring Die is a specialized ring die used in high-performance pellet mills. Unlike single-track dies, it features two concentric compression tracks that allow for simultaneous production of pellets in a double ring pattern. This results in higher throughput, uniform pellet formation, and longer service life.
โ Key Benefits:
- โ๏ธ Increased Throughput: Dual tracks enable higher pellet production (2โ5 TPH).
- ๐พ Improved Biomass Compression: Achieves tighter compaction, enhancing pellet density.
- ๐ฅ Higher GCV: Better compression and lower voids lead to improved Gross Calorific Value (up to 4,000โ4,200 kcal/kg for biomass).
- ๐ฏ Uniform Pellet Quality: Reduces fines and dust; results in consistent size and shape.
- โณ Extended Die Life: Balanced wear on both tracks increases die longevity.
- ๐จ Better Heat Distribution: Maintains uniform temperature, reducing overheating or material burn.
- ๐ช Higher Density Pellets: Densities increase from 550โ650 kg/mยณ (standard) to 700โ750+ kg/mยณ with dual track dies.
- ๐งฑ Improved Binding: Lignin activation improves due to enhanced heat & pressure dynamics.
- ๐งฐ Reduced Machine Load: Efficient discharge of material lowers strain on rollers and gearbox.
- โป๏ธ Suitable for All Biomass: Works well with wood chips, rice husk, wheat straw, napier grass, bamboo, coconut waste, etc.
