Our company recommends the double roller extruder granulator as the ideal machine for producing 3mm lime fertilizer pellets. This limestone granulator uses a dry granulation method, where powdered lime forms pellets under high pressure. Thus, it preserves the chemical properties of the lime. Unlike wet granulation, it requires no drying stage, reducing energy consumption. Ngoài ra, we can customize the roller skin with different shapes of ball socket, so customers can get precise 3mm limestone granules. Do đó, its compact design, high efficiency, and suitability for low-moisture materials make dry granulator superior to other granulation methods. Fertilizer manufacturers can reliably produce 3mm lime pellets with excellent quality.

Proper pre-processing of lime is essential for successful mineral fertilizer granulation. Before granulation, lime powder undergoes essential pre-processing steps. Firstly, grinding machine like Raymond mill ensures fine powder preparation. It can thoroughly ground the lime stone to a fine powder of 0.038 mm. Then, single shaft horizontal mixer create evenly a blend of fine lime powder with 20% water or additives.  Ngoài ra, after limestone granulation, a rotary screening machine can separate oversized or undersized particles, ensuring consistent 3mm lime mineral fertilizer pellets. By incorporating these auxiliary machines, the limestone powder granulation process becomes more efficient and consistent.
