Compound Fertilizer Production Line

Generally, SX fertilizer batching machine adopts electric weighting technology. So it can strictly feed various raw materials according to the required proportion. In this way, you can produce compound fertilizer with richer nutrients and higher quality.

Because new type vertical ferilizer shredder employs special steel crushing blades. It have a longer service life and can grind batching material into fine powder quickly. In addition, we especially use polypropylene plate as lining and there is no screen mesh. Therefore, it has strong applications for high moisture materials and is not easy to block.

In order to prepare better compound fertilizer, screening is necessary. Powder rotary screener can help you separate waste and large particles from fine batching powder. Then the waste (stones, cigarette butts, etc) will be discharged and large particles will be returned to shred again. This is beneficial for improving the purity of final fertilizer product and reducing material waste.

This mixer processes compound fertilizer with a group of double helical ribbon type blade. It can blend various organic materials evenly. This can ensure you produce fertilizer with balanced nutrients.

For large scale organic fertilizer granulation, the best hot selling equipment is rotary drum pelletizer. On the one hand, it has a large capacity, which means it can granulate more batching material into pellets. Therefore, you can finish large scale organic fertilizer granules manufacturing more quickly. On the other hand, it has low energy consumption. The power of SXZGZ-3210 rotary drum pelletizer, which can process 15-30 tons of organic fertilizer pellets per hour (100,000 ton/year and more), is only 37 kw.

In order to improve the purity of final compound fertilizer granules, it is advisable to screen it after granulation. For this, SXGS-2080 rotary screener is an excellent option. It can separate the required size compound fertilizer pellets from small or large particles. Then you can return unqualified fertilizer pellets to re-crush and re-granulate. So you will complete large scale compound fertilizer production with nearly no material waste.

Because rotary drum granulator adopts wet granulation method, which uses liquid as binder to make batching material powder into pellets. The water content of produced compound fertilizer pellets is about 15%-20%. However, in order to make fertilizer more convenient for transport, store and use, it is necessary to lower the moisture to below 10%. Here, SXHG-2424 rotary dryer and SXLQ-2424 rotary cooler are excellent choices for the excessive water removing in 150,000 t/y compound fertilizer production project.

Automatic bagging equipment can help you package finished compound fertilizer powder or pellets into 10 kg/bag, 25 kg/bag, 50 kg/bag, etc. So you can sell fertilizer to your customers in a targeted way. For capacity of 150,000 tons per year, SX especially design double buckets packaging scale and ton bag packing machine for your choice.

The higher the moisture content, the larger the size; the lower the moisture content, the smaller the size. Why? The high water content makes materials easier to stick to each other and combine with more materials. So it is easier to roll into larger fertilizer granules.

The sharp the slope, the smaller the size; the slower the slope, the large the size. However, what you need to focus on is that it is advisable to keep the angle of disc between 35° and 55°.

On one hand, you still can regulate compound pellet size by adjusting the moisture content. On the other hand, you can finish it by changing the rotating speed of drum. The higher the rotating speed, the smaller the size; the lower the rotating speed, the larger the size.

But in the process of double roller extrusion granulation, the compound granule size is only related to the size of ball sockets on rollers. The smaller the ball socket size, the smaller pellet size; the larger the ball socket size, the larger the pellet size.
