How Does A Double Roller Granulator Pelletize Your Powdery Materials By Dry Granulation Technology?

October 26, 2019

fertilizer granulator

Comments Off on How Does A Double Roller Granulator Pelletize Your Powdery Materials By Dry Granulation Technology?


In contrast to wet granulation, which requires the use of a liquid binding agent, dry granulation is the process of turning dry powdery materials into granules using extrusion forces. During the process, the tiny powder particles are forced to adhere to each other due to large compression forces, resulting in larger, multi-particle entities, ie. granules or pellets.

Double roller granulators work be forcing fine powdery materials between two counter-rotating rollers with pitted surfaces. As the powdery material is squeezed between the counter-rotating rollers with pitted surfaces, it is compacted into hundreds of separate, dense granules.

A typically double roller fertilizer granulator will produce granules with diameters ranges from 3.5mm to 10mm one at a time. However, a machine designed for large-scale production can produce dozens of granules at the same time. The granulating ratio of double roller fertilizer granulating machines is over 85%, which makes them very efficient machines for a commercial compound fertilizer production line.

The reason why dry granulating methods are popular is that no-drying processes are needed and the machines can operate at room temperature. The result is lower energy costs and fast granulating for fertilizer manufacturers. It’s not hard to see how double roller fertilizer granulators can offer great ROI rates.
