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.
β Key Benefits:
- βοΈ Increased Throughput: Dual tracks enable higher pellet production (2β5 TPH).
- πΎ Improved Biomass Compression: Achieves tighter compaction, enhancing pellet density.
- π₯ Higher GCV: Better compression and lower voids lead to improved Gross Calorific Value (up to 4,000β4,200 kcal/kg for biomass).
- π― Uniform Pellet Quality: Reduces fines and dust; results in consistent size and shape.
- β³ Extended Die Life: Balanced wear on both tracks increases die longevity.
- π¨ Better Heat Distribution: Maintains uniform temperature, reducing overheating or material burn.
- πͺ Higher Density Pellets: Densities increase from 550β650 kg/mΒ³ (standard) to 700β750+ kg/mΒ³ with dual track dies.
- π§± Improved Binding: Lignin activation improves due to enhanced heat & pressure dynamics.
- π§° Reduced Machine Load: Efficient discharge of material lowers strain on rollers and gearbox.
- β»οΈ Suitable for All Biomass: Works well with wood chips, rice husk, wheat straw, napier grass, bamboo, coconut waste, etc.
