Dry granulation equipment is one of the granulating methods widely used in compound fertilizer producing plant. The method by which dry powder materials are directly extruded into particles of a particular shape is called dry granulation method.

The main machine used in dry granulation method is double roller extrusion granulator. It mainly turns fertilizer material into pellets by the extrusion of two rollers. The fertilizer balls produced by this way always have nice quality and high purity. As a professional dry roller pressing granulator manufacturer, ShunXin fertilizer machinery has developed different types of dry granulators for meeting customers requirements.

  • What machine is used in dry granulation?

Double roller extrusion granulating machine is the most typical dry granulation equipment. It’s a newly designed granulating machine in compound fertilizer manufacturing industry. It can granulate many kinds of fertilizer materials, like sulphur, limestone, organic fertilizer dry powder, etc; and you can adjust the pellets strength according to different materials.
Based on dry granulation method, the materials are turned into balls by extruding. So the granulation process needn’t use any additives, raw materials are directly extruded into balls. That can also ensure the purity of fertilizer, make fertilizer transport and storage easily.
Furthermore, ShunXin roller dry granulation machine has a small and compact structure, that will make the operation more smoothly and improve the automation degree, reduce the production cost for customer.

  • How the machine of dry granulation is work?

As its name suggests, this type of fertilizer granulator adopts dry granulation technology. So how does it work? Let’s look at how you can use it to make dried powder fertilizer into granules.
ShunXin Double roller dry granulation machine has a simple structure. By the compact structural design, it enables your operator run the machine freely. There is an open design feeding hopper in the machine, so you can put powdery fertilizer materials into it continuously.
When making fertilizer granules, all its components, like motor, belt, gears and roller, working together naturally and high efficiently, shaping fine fertilizer granules by extrusion forces finally. If customers want to increase the hardness of the finished fertilizer granules, you can adjust our dry granulator’s roller pressure.
Moreover, if you want to make granular fertilizer with certain sizes, our engineer can tailor its roller sizes for your sides. By this way, you can get fertilizer granules with the sizes of 4 to 10 mm diameters.

  • Why dry granulation is favoured to make fertilizer pellets?

More choices in granular sizes:

Wet granulation equipment always make fertilizer into balls. But dry granulation equipment can turn fertilizer into many specific shapes. That will give customer more choices. And the diameter of granules can also be set in advance. Because of the extruding way of dry granulation, your powder material can be granulated without binder. It will avoid clumping during granulation and greatly improve the granulating rate.

More Safety and efficient in granulating process:

No binders added 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:

The fertilizer pellets produced by dry granulation method needn’t to be dried or cooled, that will greatly simplify the granulating process, save you a lot of production cost and bring you wonderful income.

  • How to choose a professional dry type granulator factory?

At first, 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 ShunXin Machinery in 2005, with 15-year business qualification, we have been the leader in Chinese fertilizer equipment factory for a long time.

Secondly, 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 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.

The last is service.

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-sale 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.

  • How to choose a suitable equipment for yourself?

1.Based on your raw materials moisture

The dry granulation equipment is suitble for compound fertilizer making plant, and also can be used in some organic fertilizer manufacturing plant. But only of the organic fertilizer raw material moisture is under 10%. If the moisture of your fertilizer material is higher than 10%, we can provide the matched drying machine to help you reduce the moisture content. If your fertilizer material is too dry, we can also equip a spray system for you.

2.What capacities do you need?

Capacity and power are the basis of choosing granulation equipment. As for our roller dry granulator, there are 3 types can be your choices. The first one is 1t/h, it costs 15kw/h. The second one is 1.5t/h, it costs 18.5kw/h. And the last one is 2t/h, it costs 22kw/h. If you care more about energy consumption, the SXDG-1T is suitable for you. Its volume is not very big, it greatly matches with small scale fertilizer making factory. If you have many dry fertilizer material and want to granulate them as soon as possible, you can choose the third one. Its capacity is the largest and the power consumption is acceptable.
