The Granulator compactor cu role 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.

For plants focusing on medium to small-scale production, Granulatorul de discuri (peletizator de tigaie) 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.

The Granulator de tambur rotativ 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, stable operation, și viață lungă de serviciu. Combined with automatic feeding, uscare, and cooling units, this system ensures high capacity—up to 30 t/h in some plants. It is widely applied for NPK-based biofertilizers requiring large output and consistent quality.
