What are the methods to produce water-soluble granular fertilizers

In the production process of water-soluble fertilizer granules. Granulation technology is one of the key links. The main granulation methods are wet granulation and dry granulation. The choice of granular fertilizer production method depends on the production conditions. Production equipment and nature of fertilizers. The methods of producing dry granular fertilizers are presented in detail below..

What is the dry granulation process?

Dry granulation is a production method of granular fertilizers. Normally it is not necessary to add liquid adhesive. This method mainly relies on high pressure or friction to compress powdered fertilizer raw materials into water-soluble fertilizer particles.. The dry granulation process is as follows:

Raw material processing. First, sift the raw powder. Remove impurities. Then mix as needed and add necessary auxiliary materials and additives.

Extrusion. In dry granulation, the raw material powder is extruded through high pressure equipment, like a roller granulator. The extrusion process compresses powder materials into sheets or strips.

Crushing and screening: The compacted material must be processed by crushing equipment and screening to form the required water soluble fertilizer particle size. The crusher breaks the flakes or strips into small particles and then passes through screening equipment to leave water soluble fertilizer particles that meet the standards.

Packaging: Finally, The prepared water-soluble fertilizer particles are packaged by a packaging machine. The packaging is to facilitate subsequent storage and transportation. Packaging machines YUSHUNXIN They are divided into single-bucket and two-bucket automatic packing machines..

What are the advantages of dry methods for producing granular fertilizers?

The advantages of dry granulation are mainly reflected in the following aspects:

Cost savings: Dry granulation does not require a drying process, and does not require the use of dryers and refrigerators, making the production process more environmentally friendly.

Simple process: since it does not involve the addition or evaporation of liquid . The dry granulation process is relatively simple and suitable for large-scale, continuous production of water-soluble fertilizers..

Great adaptability: Dry granulation can handle moisture sensitive materials and is suitable for substances that may undergo chemical changes or degradation during processing. wet granulation.

High particle hardness: Dry granulation can produce water-soluble fertilizer particles with high mechanical strength by optimizing the compaction and shaping process..

Regardless of the method used to produce water-soluble granular fertilizers. The final granulation product and the solubility of the fertilizer it can produce satisfy the market. Quality standards requirements. As technology advances. Our granulation equipment and processes are constantly improving. To improve production efficiency, reduce costs and reduce environmental impact.
