Powder Granulator Machine

Because of rich nutrients contained, manure or compound material are ideal materials for fertilizer production. They are not only beneficial for daily farm manure management but also help you make more profits. But how to turn manure into organic fertilizer pellets or batching materials to make compound granular fertilizer? You need some suitable powder granulator machines. For this, SX can provide you with various powder granulator machines for your choice. They can help you finish powdery granular fertilizer manufacturing quickly and smoothly.

How to Manufacture Fertilizer Granules from Powder?

How to produce granular fertilizer from powder? This is a thing you must know when you plan to make granular fertilizer. As a professional fertilizer equipment manufacturer, SX can provide you with powder granulation process and various powder granulation machines for your choice. And in general, process of complete fertilizer granules from powder manufacturing system you need the following machines to achieve:

load type feeder for powder granules

Load Type Feeder

You need to transport powder fertilizer to load type feeder, which can feed fertilizer making material effectively. For one thing, the steel mesh at the inlet can filter the existing powder to improve the purity of the final powder. For another, its belt conveyor can not only withstand the impact of falling materials,but also adjust the material conveying speed according to your needs. So you can produce quality powder granular fertilizer smoothly.

Powder Screening Machine

Because your material is powdery fertilizer, you cannot crush them. But if you are not satisfied with their size, you can also grind them. Then in order to prepare better powder, you need to add a powder screener after load type feeder. Rotary screening equipment will further remove waste from fine powder fertilizer.

Powder Granulator Machine

Granulation equipment plays an important role in the preparation of powder granular fertilizer. It is used in making powder chemical materials into granules. For this, you can purchase disc granulator, rotary drum pelletizer and double roller granulation machine.

Dryer and Cooler

If you use double roller granulator to prepare granular fertilizer, it is dispensable to buy dryer and cooler. However, when you start powder granular fertilizer with disc granulator or rotary drum pelletizer. You’d better use the dryer and cooler to remove excessive moisture from your granular fertilizer.

Packaging Equipment

Provided you want to make granular fertilizer continuously, an automatic bagging machine is necessary. It can help you finish powder granular fertilizer packaging  quickly and easily, so you can deliver it to your customers in a short time.

What Method Machine is Used in Organic Powder Pellets Production?

If you want to produce granular organic fertilizer smoothly, it is necessary to know how compost powder forms into organic fertilizer pellets. In general, it mainly relies on two forces to make powdery organic material in to granules. One is cohesive force between materials caused by liquid binder. Another is the resulting mechanical force of machine working. So usually , there are two kinds of granulation methods you can adopt in organic fertilizer granule production.

Wet granulation method machine for commercial fertilizer pellet making

Do you plan to prepare organic powder fertilizer pellets for commercial purpose? We recommend you choose the wet granulation method, which makes use of not only liquid cohesive force but also resulting mechanical force of machine working to process powder organic fertilizer into granules. So the final organic fertilizer particles have characteristics of beautiful appearance, uniform particle size, low pulverization rate, etc.

In order to make it more convenient to add liquid, we especially design spray devices for our wet granulation machines. Moreover, in order to fully meet your requirements, we design wet granulation machines with different mechanical forces. Therefore, there are disc granulator, stirring teeth granulation machine and rotary drum pelletizer for your choice.

Dry powder granulator machine for low cost organic fertilizer granulation

Dry granulation equipment is more suitable for those who want to prepare powder granular organic fertilizer in a simple process or at a low cost. It mainly relies on an extrusion force between two rollers to turn powder organic fertilizer into pellets. So there is nearly no water involved. In addition, the moisture of feeding material is below 10%. So you can save your money on drying and cooling, then finish the granulation of small scale organic fertilizer making at a low cost.

The typical organic fertilizer dry powder granulator machine is flat die organic fertilizer pellet making machine. In the process of granulation, the rotating roller of flat die pelletizer will press organic powder into mold. This mold will form powder compost into long cylindrical particles with the required diameter. Then the inside high strength alloy steel knives will cut them into proper length. What a simple process!

How Much Does NPK Powder Granulator Machine Cost?

In addition, in the process of choosing NPK powder granulator machine, cost is also an item you must focus on. In general, when you plan to buy disc NPK fertilizer granulator for your fertilizer production line, you need to prepare about $1,000-$16,000 for it. How about drum NPK granulation equipment? The price of a rotary drum pellet making machine is $7,200 and $69,000.

What Types of Equipment is Commonly Used in Small or Large NPK Powder Granulation?

Summarizing the feedback of our past customers, there are two kinds of NPK powder granulation that are popular. Pan pelletizer and rotary drum granulation machine. What is the difference between them? The most obvious difference is that they are commonly used on differen scales. For example:

Pan pelletizer for small scale NPK granule manufacturing

If you only plan to start a small scale NPK fertilizer pellets making, we recommend you choose pan pellet machine. A disc granulator can produce 1-6 tons of NPK powder pellets in an hour. In addition, its granulation rate can reach over 93%. That is, when you use the same amounts of N, P, K to prepare compound fertilizer particles, disc pelletizer can help you granulate more chemical fertilizer powder. There is less material that needs to be returned to re-regulate, so you can finish small scale NPK pelleting effectively.

Drum granulation machine for large scale NPK granulation

But for those who want to produce NPK powder into pellets in a large scale, rotary drum granulator is a better choice. There are two reasons. For one thing, it has a larger capacity, which can reach 30 t/h. So it can help you finish large scale NPK powder granulation more quickly. For another, this fertilizer machine is designed with rubber lining, angle irons and cleaning holes. They greatly contribute to reducing the possibility of wall sticking. Therefore, drum pelletizer can withstand the erosion of a large amount of chemical materials processing.
