Granulation technology is a critical stage in Technologie de production de biofertiliser. It transforms fine fermented materials into uniform, stable, and easy-to-apply granules. Dans un usine de fabrication de biofertilisants, the choice of granulation system depends on raw material moisture, capacité, and the physical properties of the desired product.
Bio Fertilizer Pelleting Technology and Equipment Selection
1.1 Roller Compactor Granulation Method for Dry Biofertilizer Materials
Le granulateur de compacteur à rouleaux is ideal for dry materials with low moisture content. It compresses fine biofertilizer powder into dense sheets and then crushes them into granules. You can control roller pressure and spacing to adjust particle size and compactness. This method requires no drying or binder, which saves energy and reduces cost. It is often used in bio NPK fertilizer production or other formulations that need high mechanical strength.
2.2 Disc Granulation Technology for Small-scale biofertilizer manufacturing (1-5TPH)
For plants focusing on medium to small-scale production, the disc granulator (banc de panoramique) offers a cost-effective option. It works through rolling and layering, where powdered materials and liquid binders agglomerate into spherical granules on a rotating disc. Operators can easily regulate granule size by adjusting disc angle, rotation speed, and binder amount. This method is highly efficient for compost-based biofertilizers with moderate moisture content.
3.3 Rotary Drum Pelleting Process for Large-Scale Biofertilizer Production
Le granulateur de tambour rotatif is suitable for continuous and large-scale bio fertilizer production lines. The rotating drum rolls and sprays materials, forming round and compact granules. It features uniform coating, fonctionnement stable, et une longue durée de vie. Combined with automatic feeding, séchage, and cooling units, this system ensures high capacity—up to 30 ème in some plants. It is widely applied for NPK-based biofertilizers requiring large output and consistent quality.
