In the fertilizer production line, the main role of the screen is to grade the fertilizer after granulation, ensure the uniform size of the finished particles, remove too large or too small particles, and improve product quality. The accuracy of the screenermachine directly affects the production effect of the fertilizer granulator and the market competitiveness of the final fertilizer.
1. The screeneraccuracy affects the uniformity of fertilizer particles
In the NPK fertilizer production line, the particle size of the fertilizer is directly related to the fertilization effect. If the accuracy of the screenermachine is too low, a large number of particles that do not meet the standard will be mixed into the finished product, resulting in uneven particle size, affecting the dissolution rate of fertilizer and nutrient release, and ultimately affecting crop absorption.
2. Low precision screenerleads to high return rate
If the screeneraccuracy is insufficient, too many unqualified particles need to re-enter the fertilizer granulator for secondary granulation, which not only increases energy consumption, but also reduces production efficiency. At the same time, too many times of return may lead to uneven water content of the material, affect particle strength, and even cause the granulator to block the material.
3. Affect the appearance and market competitiveness of fertilizers
High quality compound fertilizer products need to have a uniform appearance and round particles. If the screeneraccuracy is not enough, it will lead to the inclusion of powder or debris in the finished product, which will reduce the appearance quality of the product and affect the market sales. Especially in the export or high-end market, customers have higher requirements for the consistency of fertilizer particles, and the quality of screeneraccuracy directly determines the competitiveness of the product.
4. Select the right screenermachine to improve the screeneraccuracy
Common fertilizer screenerequipment includes drum screenermachine and vibrating screenermachine. Roller screen is suitable for large-scale production, high screenerefficiency, suitable for NPK and other compound fertilizer production. The vibrating screen is suitable for fine screening, which can effectively remove the fine powder and improve the quality of the finished product. When selecting the screenermachine, enterprises should choose the appropriate screenermethod according to the production capacity requirements and particle specifications, improve the screeneraccuracy and optimize the quality of fertilizer.
