Learning The Working Process Of A Dry Granulation Machine

Posted on April 13, 2020 by grxksr

Dry granulation machine implements a granulation technique that never requires the addition of water or binder when granulating. In addition, you don’t have to dry the finished pellets by using the drying machine. Generally speaking, this technique makes use of the crystal water available in the raw materials, which shapes them by strong extrusion.

So, the dry granulation equipment combines compressing, crushing, and granulating. And to some extent, this equipment makes up for the deficiency that comes with the wet granulation method. This is in terms of the requirements of raw materials and the granulating process.

What Entails the Dry Granulation Process?

Typically, the dry granulation machine implements the dry granulation process to create fertilizer granules. It’s also applicable to creating pellets without using liquid solutions. This is mainly because the granules might be sensitive to the heat or moisture. So, it shapes the granules by simply pressing on the materials.

It’s also worth noting that you could use a double roller press machine to create fertilizers through dry granulation. Usually, the counter-rotating rollers offer a strong extrusion force that helps in pressing materials into relatively large tablets. Inside the machine, it consists of a unique structure that plays a vital role in crushing these tablets and making them into pellets.

What Are the Dry Granulation Steps?

In general, we can divide the entire granulation process into three steps. These include the preparation of materials, feeding into the equipment uniformly, and granulation. Let’s take a look.

– Preparation of materials. When it comes to dry granulation, the raw materials should contain crystal water, or perhaps the moisture content is approximately 5%. For granulating, you’d instead use the 80 mesh to 300 mesh materials. When it’s too crude, the finished pellets might be uneven. On the other hand, for the fine powder, it is quite challenging to granulate. As a result, you must prepare appropriate raw materials before starting dry granulation.

– Feeding uniformly. When you are feeding materials into your dry type granulation machines, continue feeding uniformly. This is very important to the entire process. The roller sheets are usually easy-to-damage parts. That means that uniform feeding might prolong the service life of those roller sheets. What’s more, they will also play a significant role in improving the granulation rate.

– Granulation. In this stage, the counter-rotating roller sheets will basically press the materials you fed into large tablets by making use of strong extrusion force. After that, the inner structure of your machine will crush those tablets and granulate. Lastly, the finished pellets will be discharged from the machine’s outlets.

You should know that the dry granulation process has no wastewater or gas emission. That means you won’t be causing any harm to the environment when using this piece of equipment. Are you concerned about the high prices of dry granulation facilities? Or perhaps you are looking for a professional manufacturer of fertilizer equipment? You can undoubtedly get a supply which meets your needs, whether for the profession or costs.

The Function Of Compound Fertilizer Granulation Equipment

Posted on September 11, 2019 by grxksr

Compound fertilizer pellets granulation machines are used to produce NPK pellet fertilizer from powder. When it comes to investing in the best equipment for your production line, you need to understand the difference between the two main methods of producing fertilizer granules: dry granulation and wet granulation. With the dry method, extrusion force is used to mechanically press and compress NPK powder into pellets. With wet granulating, a liquid is added to fertilizer powder before it is added to a drum pelletizer. The liquid is needed to provide a binding agent for raw powders that have a low moisture content. Buying the right type of granulation pelletizing machinery for the raw materials you have access to is essential for the running of a profitable compound fertilizer production line.

Double roller extrusion granulator in fertilizer granulation plant

Wet Granulating Technology

When using the wet granulation method, the fertilizer pellets produced have a high-moisture content, so they require drying, solidifying and cooling processes before packing. There are various machines that can be used for wet granulation including spray granulation machines, disc pan granulation machines, rotary drum granulators, and tow spray granulating equipment. The liquid to facilitate the formation of compound fertilizer granules from low-moisture content powder must be a good binding agent. It needs to be volatilizable and non-toxic. Some of the most common liquids used are ethyl alcohol and isopropanol. If the right liquid binding agent is not used, the end product will crumble and separate following the drying process.

Double Roller Press Granulator

A double roller press granulator uses extrusion forces to produce NPK fertilizer pellets. No drying processes are necessary with this type of machine. It can be used to produce fertilizer granules in a wide range of sizes and shapes. During the extrusion granulation process, powder fertilizer is vigorously aggregated at high pressure. The power is then forced through rollers to produce granules. Since no cooling, drying or solidifying processes are needed, double roller press granulators are perfect for small to mid-sized compound fertilizer plants that perhaps don’t have the floor space or funds to invest in industrial drying machinery.

Disc Pan Granulation Machine

One of the main benefits of a disc pan granulator is that the cost is much lower than that of a rotary drum granulator. Furthermore, the machine can be used for a multitude of applications. The disc pan is manufactured from reinforced iron to make it durable. Furthermore, the interior of the disc pan is coated with anti-corrosion plastic glass material, which is very easy to clean and maintain. During production, a disc pan granulator has a surprisingly low noise output and such granulators are loved around the world because of their reliability. Some of the fertilizer manufacturers already using disc pan graduations can produce over 50,000 tons of compound fertilizer granules annually.

Final Production Processes

During the final stages of compound fertilizer production, the pellets undergo screening and unqualified granules are routed back to the start of the production line. The screening equipment used depends on the unique sieving specifications of the manufacturer. After screening, the pellets are often coated to improve the physical characteristics of the end product.
