How to Make NPK Granules?

NPK granules play a crucial role in the agricultural industry by providing plants with the essential nutrients needed for growth. NPK stands for Nitrogen, Phosphorus, and Potassium, the three key components in fertilizers. Let’s explore the different methods of producing NPK granules and highlight the advantages of each technique.

Wet Granulation Technology

Among the various methods available, wet granulation is one of the most widely used approaches for NPK granule production. This process involves combining NPK raw materials with water to form a wet mixture. The mixture is then passed through a granulator, where it is shaped into granules. Two common types of granulators utilized in this process are the drum granulator and the disc granulator.

The drum granulator features a large rotating drum that applies a tumbling action to form the granules. On the other hand, the disc pelletizer utilizes a spinning disc to achieve the same result. Both machines are highly efficient and capable of producing high-quality NPK granules. Notably, Shunxin’s NPK granulation machines are specifically designed to handle the wet mixture and shape it into uniform-sized granules.

Dry Granulation Technology

Dry granulation technology, in contrast, involves compacting the raw materials without the addition of liquid. This method is particularly suitable for materials that are sensitive to moisture or heat. SX double roller press granulator is a perfect choice for NPK dry granulation. This granulator employs two rollers that press the material into a sheet or ribbon. The sheet is then broken down into granules through a process known as extrusion. The press granulator operates with great efficiency and produces granules with uniform size and shape.

The selection between wet and dry granulation methods depends on several factors, including the characteristics of the raw materials, desired granule properties, and production scale. Regardless of the chosen method, Shunxin’s NPK granulation technlogy are versatile and capable of meeting the requirements of both small and large-scale production. These machines are designed with user-friendliness in mind, featuring easy-to-use controls and maintenance-friendly attributes.

In addition to the granulation machines, Shunxin offers a comprehensive range of equipment that can be used in the production of NPK granules. This includes static batching machines, double shaft mixers, rotary screening machines, packing machines, and palletizer robots. These machines work in harmony to create a complete and efficient production line that ensures reliability and cost-effectiveness.

The Difference Between Dry And Wet Granulation

Are you searching for difference between dry and wet granulation machines? Here’s everything you need to know about the difference in these processes and when it’s appropriate to choose one over another.

In the wet granulation process, the dry primary powder is mixed with a liquid solution. This liquid solution is a volatile solvent. The solvent needs to be volatile as it needs to be removed later by drying. Also, it needs to be non-toxic. Some of the common solvents used in this process include ethanol and water, among others. These liquids can be used alone or in various combinations.

As far as the liquid solution is concerned, it can be solvent based or aqueous based. In some cases, water is not enough and in such situations, a liquid solution containing a binder is used. Once powder has become denser, the process of granulation is started. As far as this process is concerned, its complexity depends on the powder characteristics as well as the equipment used in the process. In the typical method, a sieve is used where the wet mass is forced through this sieve for production of organic fertilizer granules or compound fertilizer manufacturing.

These wet granules are then dried in order to produce the final product. In the subsequent stages, the granules are broken apart. Wet granulation is often preferred as many active substances cannot be processed through direct compressing which is nothing but dry granulation. Thanks to the use of modern technology, there is absolutely no problem with wet granulation method is even when used with sensitive active substances.

As far as the dry granulation method is concerned, it should be clear from its name that no liquid solution is used in this process. This is typically due to the reason that the product that needs to be granulated is too sensitive to heat or moisture or does not compress effectively. Making granules without use of moisture is a challenging process. It typically involves compaction and reduction of the size of the mix in order to produce a free flowing granular blend. In this process, the powder particles are put under high pressure using various machines. This processing can be done in various ways that involves use of various machines such as a roller fertilizer granulator. All these methods have their own advantages and are used for different kinds of materials. In short, a variety of machines and processes are used for dry granulation method of processing.

When it comes to choosing between these 2 processes, it should be clear by now that dry granulation is much more challenging and complex process as compared to wet granulation. This is why, wet granulation is the preferred method of processing though in some cases, dry granulation becomes necessary due to the active substances being too sensitive to the moisture or due to other problems. Various types of machines are used for both these processes. The machines need to be chosen carefully and after thorough research as even a slight mistake can lead to huge problems in the granulation process.
