On February 24, 2026, a customer from Indonesia inquired about an NPK fertilizer granulation line. He wants a production line with a daily capacity of 100 tons (24 hours). He also requires the fertilizer granules to be round and measure between 2 and 5 mm in diameter. Based on his raw materials—using urea or ammonium sulphate for nitrogen, diammonium phosphate for phosphate, and potassium sulphate or potassium chloride for potash—we recommended the following NPK production turnkey: dynamic batching machine → SXSJ-0830 double shafts horizontal mixer → 1.5m*6m drum granulator → SXGS-1240 rotary drum screening machine → SXHG-1212 rotary dryer → rotary cooler → coating machine → packing machine.
What’s the design of a NPK granule production factory?
Would you like to know the design of a NPK granule production factory? The design connects all equipment in a continuous material flow. It starts with the dynamic batching machine weighing each raw material in sequence. The double shafts horizontal mixer then blends them into a uniform powder, which feeds directly into the drum granulator. Inside the granulator, tumbling action with water or steam forms soft 2–5 mm granules. Next, the rotary drum screening machine separates the granules: qualified sizes continue, while rejects cycle back for re-granulation. The accepted granules then go through the rotary dryer to remove moisture and harden, followed by the rotary cooler to bring down temperature. After that, the coating machine adds an anti-caking layer, and finally the packing machine weighs and bags the finished NPK product. This sequential design keeps the process simple and efficient.
Granulator recommended for a 100 ton/day NPK production line (2-5mm granules): A rotary drum granulator
If you need a steady 100 tons per day of 2–5 mm NPK granules, and your raw material is a mix of urea, DAP, and potash, you should choose a rotary drum granulator. This is because it handles sticky materials smoothly. When you add a little water or steam inside the drum, the tumbling action forms round NPK fertilizer granules and prevents potash from caking. As a result, this machine scales easily for your 100 t/d target and gives you uniform, strong NPK fertilizer pellets without clogging.
What equipment is needed for a 100TPD NPK granule production factory that produces 2–5 mm fertilizer granules?
Do you want to learn about what equipment is needed for a 100TPD NPK granule production factory that produces 2–5 mm fertilizer granules? A wet fertilizer granulation line provides the answer. It includes: dynamic batching machine → SXSJ-0830 double shafts horizontal mixer → 1.5m*6m drum granulator → SXGS-1240 rotary drum screening machine → SXHG-1212 rotary dryer → rotary cooler → coating machine → packing machine.
After screening, the rotary dryer removes extra moisture. It helps improve granule strength. Then, the rotary cooler lowers the pellet temperature. This helps prevent caking during storage. Next, the coating machine adds anti-caking agent or nutrients. It improves the appearance and flowability of NPK fertilizer. Finally, the packing machine weighs, fills, and seals the bags. This makes shipment faster and easier.
