Granulation Principle: Dry Granulation Technology

✅Dry Granulation
Unlike wet granulation methods (like rotary drum granulators), this process does not require the use of binders or drying steps. It relies purely on mechanical pressure for granule formation, making it cost-effective and energy-efficient.
✅Extrusion Process
A powerful motor drives two counter-rotating rollers that compress powder materials into flat, dense sheets or tablets under high pressure.
✅Crushing & Sizing
The large tablets formed during extrusion are directed into a crushing chamber, where they are broken into uniform granules suitable for agricultural use.
✅ No Drying Required
Since moisture isn’t added during granulation, there’s no need for a separate drying process, which significantly lowers energy consumption and streamlines production.

Working Flow:

✅Feeding
Powdered fertilizer materials are introduced into the machine through a specially designed hopper.
✅Extrusion
The materials are tightly compressed between the two rollers, forming solid flakes or tablets.
✅Crushing
These tablets pass through a crushing unit where they are fragmented into granular form.
✅Screening
The granules are screened to separate out oversized or undersized particles, ensuring consistent granule size.
✅Powder Recycling
Unqualified fine powder or non-granulated material is collected and recycled back into the feed hopper for reprocessing.
