A fertilizer granulator should match your formula, feed condition and required output rather than only the machine price. If you process low-moisture powder and want a shorter production route, a dry double roller granulator can form pellets at room temperature without adding water or installing a conventional drying section.
When Does Dry Extrusion Fit Your Material?
In dry granulation, powder is compacted under pressure instead of being agglomerated with a liquid. For fertilizer production, this route can suit NPK materials, bentonite, phosphate rock, limestone and other powders that respond well to compression.
The target page recommends keeping feed moisture below 10%. Stable particle fineness and uniform mixing also matter because inconsistent feed can affect compaction and final granule quality. Before selection, test your actual formula rather than assuming every powder behaves in the same way.
How Much Capacity Do You Need?
For an initial project, an industrial roller fertilizer granulator can operate as the core machine in a compact line. When your target exceeds one machine’s output, 4–20 TPH dry extrusion granulation systems can use multiple granulators with a distributor and higher-capacity upstream and downstream equipment.
A 120 TPD NPK granulation project shows how two roller granulators can be combined when the daily output and operating schedule require about 6 TPH.
What Determines Pellet Size and Shape?
The machine page presents a roller press fertilizer pelletizing solution for producing 3–10 mm granules. Pellet size and profile depend mainly on the ball sockets machined into the roller sheets. Therefore, confirm diameter, shape and strength before ordering.
Different custom fertilizer pellet roller sheets can produce pillow, semicircular, stick, pill, walnut, flat-ball or square-bar profiles. Screening then separates qualified pellets, while off-size material returns for reprocessing.
