In the fertilizer production line, the sifter is an important equipment to ensure the uniformity of fertilizer particles and product quality. Whether it is organic fertilizer production or npk fertilizer production lines, the screening process directly affects the particle size, purity and market competitiveness of the finished product. Reasonable configuration of the sifter can not only improve the production efficiency of the fertilizer granulator, but also reduce waste and improve the overall economic benefits.

1. The role of sifting machine

The main function of the sifter is to classify different specifications of granular fertilizer, screen out qualified products, and return unqualified particles to re-granulation or crushing. This process can ensure the uniform particle size of the finished fertilizer and avoid the effect of fertilization due to too large or too small particles.

2. How does the sifter affect the quality of fertilizer?

• Improve particle uniformity: The fertilizer particles after screening are more uniform, which is conducive to precise control of fertilization and avoid uneven fertilizer efficiency caused by different particle sizes.

• Reduce dust and impurities: effectively eliminate powder, debris and impurities, improve the purity of the finished fertilizer, so that it meets market standards.

• Improve granulation efficiency: After screening, the particles that do not meet the standard can be returned to the fertilizer granulator for reprocessing, reducing raw material waste and improving the yield.

• Optimised packaging and transport: uniformly sized pellets are easier to pack, store and transport, avoiding impact on product quality due to powder or caking.

3. Common type of sifter

In npk fertilizer production lines and organic fertilizer production, common sifters include:

• Roller screener machine: suitable for large particles of fertilizer, screening accuracy is high, stable operation.

• Vibration screener machine: suitable for fine particle fertilizer, screening speed is fast, strong adaptability.

Conclusion

The sifter plays a key role in the fertilizer production line, which not only affects the quality of the finished product, but also determines the work efficiency of the fertilizer granulator. Choosing the right sifter can effectively improve the overall level of npk fertilizer production line and make fertilizer products more competitive in the market.
