With the development of science and technology, people began to make waste into fertilizer for recycling to protect the environment and soil quality. Humans use these organic wastes to produce organic fertilizers, and also use fertilizer spreaders to produce organic granules, which is a great way to turn waste into treasure. Therefore, as a favorable substitute, organic granulation is returning to people’s lives. Common organic fertilizer granulators include: npk fertilizer granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, all kinds of granulators have their own production characteristics, and the fertilizer granulator machine price vary.

Compared with powdered fertilizers, organic matter granulation has several advantages:
•Easy to use: Powdered fertilizers have low relative density and are easily blown away by the wind when applied to field crops. So granular fertilizers are dry and dense compared to powdered fertilizers. Therefore, they are easier to handle and apply. The dry granules are also odourless, thus alleviating the unpleasant odor associated with raw manure.
•Convenient storage: thousands of granules can be used as needed. It can be stored on the farm, if required, and transport costs are much lower.
•Environmental protection: granular fertilizer can reduce the hygroscopicity of fertilizer, therefore, it can reduce environmental pollution.
•Enhance fertilizer efficiency: adding some inorganic components to granular fertilizer can enhance fertilizer efficiency. If inorganic ingredients are added to the powdered fertilizer, it is easy to absorb moisture and agglomerate.
• Reduce runoff: Excessive application of raw fertilizers can lead to excessive nutrient loss from the soil and can harm the surrounding environment. Dry granules help prevent run off as they are only used when needed.
• Obtaining powdery materials must be carried out under low moisture conditions, and the materials need to be crushed. The biggest limiting factor in the production of organic fertilizers is that the water is difficult to remove, and the fertilizers need to be dried. Making granules does not require drying, and high heat will be generated during the granulation process, so it is very convenient to just cool the fertilizer.
