Dry Granulation Machine

Dry granulation machine is a type of fertilizer granulating machine that utilizes the dry granulation method. This process only involves mechanical manipulation of the powder material, without any chemical reactions taking place. Hence, there is no need for subsequent drying procedures, resulting in low energy consumption. Moreover, the equipment requires fewer auxiliary materials, leading to improved particle stability as well as convenient storage and transportation. As a professional fertilizer equipment manufacturer, SX has developed two dry granulation machines to cater to customers’ diverse needs. These machines include the double roller extrusion granulator and the flat die pelletizer, both of which allow for the easy production of high-quality fertilizer granules.

What is the dry granulation method for fertilizer?

In the realm of fertilizer manufacturing, dry granulation and wet granulation stand out as the two most widely recognized methods. Dry granulation is a process where granules are formed purely through mechanical means, devoid of any liquid solution. Unlike its wet granulation, dry granulation does not involve any chemical reactions. Instead, it employs a roller extrusion process to compress powder materials containing less than 10% moisture content, transforming them into flakes or blocks. Following this, crushing and sieving the flakes and blocks, ultimately becoming granular materials that meet the required standards for application. In essence, dry granulation epitomizes an efficient and controlled method, yielding high-quality granules for optimal agricultural use.

What machine is used in dry granulation?

The double roller extrusion granulator and flat die pellet mill are the primary equipment used for dry powder fertilizer granulating. As their names imply, these machines transform fertilizer materials into pellets through extrusion. And this unique granulation process eliminates the need for additives as the raw materials are directly extruded into compact balls. So, what sets these two dry powder granulator machines apart?

Double roller granulator

The double roller extrusion granulator is a highly sought-after machine for the production of NPK fertilizer. With its capacity of 1-3 t/h, it has the capability to produce granules ranging in diameter from 3-10 mm. Not only that, it can also support other equipment, allowing for the creation of a small production line that enables continuous, mechanized production, meeting the desired capacity. Additionally, it can cater to specific requirements for granule size and shape. So we offers versatile ball socket customization options, including pillow, semicircle, stick, pill, walnut, fat ball, and square ball shapes. In other words, it is a versatile and efficient solution for all your fertilizer production needs.

Flat die pellet mill

The flat die pelletizer holds a crucial role in the granulation of various organic substances following fermentation. With a capacity of approximately 1-2.5 t/h, it is well-suited for initiating small-scale organic fertilizer production. Additionally, this device is capable of combining with a diverse range of molds, allowing for the production of columnar particles with varying diameters to cater to the diverse needs of customers. The particles processed by this machine possess not only a smooth surface and moderate hardness but also the ability to maintain the internal nutrients within a dry granulation process.

Why dry granulation machine is favoured to make fertilizer pellets?

As mentioned above, both dry granulation and wet granulation are good granulation methods in fertilizer preparation. According to statistics, in the process of fertilizer production, a large part of fertilizer producers like to use dry granulation method. So why can dry granulation attract them?

More choices in granular sizes

Our dry granulation equipment offers you a wide range of options when it comes to shaping your fertilizer. Unlike wet granulation equipment, which only produces spherical granules, our machinery can transform your fertilizer into various specific shapes. What’s more, you have the flexibility to pre-set the desired diameter of the granules. With our efficient extruding method, there’s no need for binders during the granulation process. This not only prevents clumping, but also significantly improves the overall granulating rate. So why settle for limited choices? Choose our dry granulation equipment and enjoy the benefits of enhanced customization and improved efficiency.

More safety and efficient in granulating process

You don’t need add binders to the granular materials. It can make the granulator work more efficiently and continuously in a long time. Meanwhile, it also ensures the pure, quality of the granular fertilizer. Working in a no binder added environment, the operator can run it more safety.

Simplify the granulating process

If you choose dry granulation method to make fertilizer pellets, you don’t need dry or cool fertilizer granules, that will greatly simplify the granulating process. For this, it can save you a lot of production cost and bring you wonderful income.

How to choose a professional dry granulation equipment manufacturer?

In addition to determining the type of machine you need, it is also important to choose a reliable company. SX Engineering Equipment Co.Ltd. is absolutely an excellent choice for you because we can provide you with the best service.

Pay attention to the qualification and scale of the factory

It’s obvious that the longer the factory is established and the large the scale is, the more worth it is worth knowing and choosing, since the foundation of SX Machinery in 2005, with 15-year business qualification, we have been the leader in Chinese fertilizer equipment factory for a long time.

The design of dry granulation machine

Dry granulator designed with great technology would have higher quality and makes more profits for you. According to the dry granulation principle, we designed our double roller dry granulator and flat die pellet mill with advanced technology. shorten the granulating time, improve the granulating rate and ensure the high quality of fertilizer pellets.The materials of which the machine is made are mainly medium carbon steel plate and channel steel The high hardness of them makes the granulator more wearproof. That will prolong the working life of the machine and reduce your maintenance cost.

Good service experience

Good service is an important aspect of improving your user experience. That not only can help you choose you ideal equipment, but also is the guarantee that you can use the machine for a long time. Through 15 years domestic and foreign trade experience, we have attached different kinds of customers.We have also made amounts of orders According to different questions from customers feedback and their assessment, we are constantly improve the relevant service, such the pre-sales service installation and commissioning guide, operation and maintenance guide and after-sales service. If you want to learn more about our machine and contact us,we will arrange customer service agent to recommend the appropriate equipment for you. And there are technicists help you install and operate the machine, if the equipment has some something wrong, they can also teach you how to deal with the matters.
