Granulation using roller compaction is an efficient method for transforming powder materials into solid granules. The roller compactor dry granulator achieves this by compressing powders between rollers with semi-circular grooves, producing stable granules without the need for steam or binding agents. With a design that includes a feeding system, roller compaction unit, and shaping/screening mechanism, it offers stable, continuous production. This granulating technology is suitable for fertilizers like ammonium sulfate, which can be challenging to granulate using other methods. Additionally, its application extends beyond fertilizers to other industries requiring efficient granulation of powder-based materials, thanks to its ability to handle a wide range of granular products.
