Double roller press granulator is the key equipment for fertilizer granulation. And it is suitable for making small scale organic fertilizer pellets and compound fertilizer granules. But if you want to make large scale fertilizer granules, it can also meet your requirements. In addition, it adopts dry granulation method to make fertilizer, which can reduce the cost of drying and cooling. So top 1 dry fertilizer granulation machine is none other than it. Besides double roller granulator, we can also provide you with corresponding machines to setup a complete double roller fertilizer granulation plant.

What kind of pellets can extrusion granulator make?

When you want to use extrusion granulator to make pellets, you need to know what kinds of granules can it produce. In general, there are three types of granules in the following:

npk compound fertilizer making from double roller granulator

Compound NPK Fertilizer Pellets Making

Double roller press granulator is widely used in compound NPK fertilizer production. It can supply nitrogen, phosphorus and potassium to crops in a balanced way. And if you want to make 17:17:17 and 20:10:10 NPK fertilizer pellets, it can also meet your needs. In addition, you can also use ammonium chloride, potassium chloride, ammonium bicarbonate and potassium sulfate, etc as materials to make compound fertilizer pellets in extrusion granulator.

Organic Fertilizer Granules Production

This machine is also suitable for making organic fertilizer granules. When you want to dispose of animal manure and organic waste, you can use double roller granulation machine to produce organic fertilizer granules. Compared with other organic fertilizer granulators, you can turn material into organic fertilizer pellets by using this machine at a lower cost.

Other Chemical Particles Manufacturing

In addition to the above two types, the roller granulator can also produce other chemical granules. Such as snow melting agent and bentonite particles, etc. It can finish the task quickly and easily. So as a multi-functional granulator, double roller press granulator is the best choice for you.

What method does double roller granulator adopts?

If you want to produce high-quality fertilizer, you must start with the equipment itself.At this time, the double roller granulator produced by our company can meet this requirement.

If you want to use this machine to make granules, you need to further know what granulation method is suitable for it. For this, it adopts dry granulation method, which turn dry powder materials into pellets without adding binder and water. Because this machine accepts the moisture of material below 10%. In addition, it makes use of extrusion force between the two rollers to granulate fertilizer. And after granulation, you don’t need to dry and cool fertilizer granules. It can effectively reduce the cost of drying and cooling.

What is the different from rotary drum granulation machine?

Both double roller press granulator and rotary drum granulation machine are the pelletizers. And they can produce organic fertilizer and compound NPK fertilizer. But there are some differences between them.

What is the price of double roller press granulator?

Double roller press granulator price

The favourable price is also an important advantage which attracts fertilizer production projects to purchase extrusion granulator. Generally speaking, the price of a double roller press granulator is $3,500-$5,000. Why does it has such an economical price? For one thing, it has a compact design and a capacity of 1-2 t/h. The smaller the capacity, the lower the price. For another, SX is a source factory for fertilizer equipment manufacturing. So there is no extra charge during the transaction.

Top 2 double roller extrusion granulation fertilizer line in SX

In order to produce fertilizer pellets continuously with double roller granulation machine, double roller granulation line is a better option. There are 2 hot selling double roller extrusion granulation fertilizer line for your choice. Capacity of 1 t/h and 3 t/h fertilizer making lines. The details are as follows:

1 t/h Double Roller Fertilizer Granulation Plant

Provided you plan to make more small scale organic fertilizer and compound fertilizer, you can choose our 1 t/h double roller extrusion granulation fertilizer making line. By batching machine, crusher, mixer, screener, double roller granulator and packaging scale, it can help you finish fertilizer production quickly and easily. In addition, because of less equipment using, it has an economical price.

3 tph extrusion granulation line

3 t/h Extrusion Granulation Manufacturing Line

And when you need a business plan for producing 3 t/h fertilizer pellets, but no need wet granulation method. SX 3 t/h extrusion granulation manufacturing line is a better option. You only increase one double roller granulator in this production line. This means two roller granulators. And the other fertilizer making machines is the same as 1 t/h double roller extrusion fertilizer granulation plant.

How to solve the problems when you use the extrusion granulator?

During the granulation process, there may be problems with the pressure roller gap and the alignment of the ball and socket in the double-roll extrusion granulator. This is when you need to require adjustments.

5 reasons to make you convince to choose our double roller granulator

Double-roller extrusion granulation is the granulation of materials at room temperature. Compared with other methods, drying measures such as fuel oil and gas are not required.

You only need to use the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.

Due to the omission of the drying process and the low return ratio (accounting for about 15% of the total feed volume of the extruder), the process is simple and you can invest lowly.

There is a wide range of raw material routes for roller extrusion granulation. There are more than 20 kinds of materials that have been successfully used for extrusion granulation: ammonium nitrate, potassium sulfate, etc. In addition, the extrusion granulation process can flexibly realize the replacement of product formulas in a very short period of time. And a set of equipment can produce more than 30 formulas of products.

The capacity consumed by roller extrusion granulation is only electricity. Environmental protection has no discharge of three wastes, which is in line with the country’s basic national policy on environmental protection. And it also in line with the development strategy of our company’s environmental protection.
