Roller granulator is commonly used in the NPK fertilizer production line, it is ideal granulator machine for fertilizer, let’s see the advantages of the roller granulator:

1. The material is forced to be compressed and molded by the pressure of the roller granulator, without adding any wetting agent, and the purity of the raw material is guaranteed.

2. The compound fertilizer production line has the advantages of short process flow, low energy consumption and large output.

3. Dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process.

4. The strength of the granules is large, and the increase in the bulk density is more significant than that of other granulation methods. It is especially suitable for occasions to increase the specific gravity of the product.

5. Large operating flexibility, suitable for a wide range of raw materials, high output, low power consumption, and the size of the extrusion force can be adjusted by adjusting the hydraulic pressure.


The compound fertilizer production line is equipped with a twin-roll fertilizer granulator machine with short process flow, low energy consumption and large output. The dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process. The particle strength is high, and the increase in bulk density is more significant than other granulation methods. It is especially suitable for increasing the bulk density of products. The operation flexibility is large, the adaption range is wide, and the squeezing force can be adjusted by hydraulic pressure.
