📢 Why These Specifications Matter?

Pellet Diameter & Counter Bore: Determines the final pellet size and smooth extrusion.
Compression Bore Length & L/D Ratio: Affects pellet durability, density, and production efficiency.
Relief Hole & Depth: Prevents blockage, ensures smooth die operation.
Gross Calorific Value (GCV): Higher GCV means better combustion efficiency and energy output.
Bulk Density: Higher density pellets are easier to transport, store, and burn efficiently.

By selecting the right die bore specifications, you can enhance production efficiency, reduce maintenance costs, and maximize pellet fuel quality.
