Why Fertilizer Manufacture Use Machine to Convert Powder to Granules?

To improve the utilization rate of powder fertilizer

Powder fertilizer granulation technique is a manufacturing method that converts powdered materials into granular fertilizer. Кроме того, this technology not only reduces dust pollution, but also enhances labor operations, material storage and transportation, and fertilizer utilization.

To meet requirements of the granulation production line

You can use our pelletizers for making the powder into granules to satisfy the needs of the finished product production process. They can prevent segregation, bubble pulse, agglomeration, obsorption and bridge actions, as well as other negative impacts in succeeding operating processes such as drying, screening and packaging.

To provide plant nutrients by powder granulation

Granular fertilizers produced by our granulators are more easily absorbed and utilized by plants than powdered forms, and the release rate of granular fertilizers is more stable to meet the growth needs of plants.

To improve the physical properties of materials

The granulator can improve the physical properties of powder materials, such as improvement of porosity, specific surface area, heat transfer, и т. д..

Wide range of applications

Powdered fertilizer granulation technology has a wide range of applications, including not only the production of various types of fertilizers such as chemical, organic and compound fertilizers, but also the manufacturing of granular substances in other industries such as chemical products and food additives.

Вершина 2 Powder Granulation Techniques You Must Know

According to different process requirements and material properties, the main powder fertilizer granulation technology includes wet granulation и dry granulation. The powder granulation machine currently available on the market can also be divided into various types.

Wet Powder Granulation Machine

А wet granulator is a device that mixes powdered or granular materials with a certain percentage of liquid, and then shapes and treats them to form pellets by the action of specific equipment and mechanical forces. Кроме, this granulation method is commonly used in the treatment of suspensions и the coating of granules.

Our typical wet granulation equipment include new type organic Fertilizer granulator, rotary drum churning granulator, disc granulator и Ротари -барабанный гранулятор.

Stirring granulation method makes liquid or binders infiltrating into the solid fine powder by properly stirring, so that the liquid and solid fine powder come into close contact with each other, resulting in bonding force and squeezing into balls.

The most common mixing method is accomplished by the turning and rolling motion of a disc или drum. The forming method can be divided into rolling, mixed and powder agglomerates.

They mainly consists of cylinder (disc), feeder machine, spraying device and driving device.
After the powder or granular raw material enters the drum (disc), you need to spray the liquid evenly on the powder surface by the spraying device. Under the specific pressure produced, the machine begins to rotate and extrude to agglomerate into balls.

It is suitable for pharmaceutical, еда, ceramic, fertilizer, mineral processing, fine chemical industry, и т. д..

Simple equipment structure; easy to operate and maintain.
High transmission efficiency; large single machine output of granular fertilizer.
The pellets formed are easy to dissolve quickly and have strong moisture permeability, which makes plants absorb quickly.

Poor granule uniformity; low moulding rate.
It often requires dewatering and drying after granulation.
The fertilizer plant needs to set up drying equipment.
The decrease of moisture after granulation has an effect on reducing pellets’ compactness and hardness,or even making them easily broken.

Dry Powder Granulation Machine

The dry granulator is a device for shaping powder or granular materials through compression, сокрушительный, and vibration. Более того, it frequently occurs in the production of biological granules, powder metallurgy, ferrous metallurgy, chemical materials, and other applications.

Dry granulator usually applies the compaction granulation method, which can confine the powder materials to be granulated in a specific space and compress them into a dense state by applying an external force. According to the physical properties of the external force, this method contains two types: die pressing method и extrusion method.

Relatively, we have two types of dry granulators, which are flat die granulator и double roller extrusion granulator.

Flat Die Pellet Mill for Powder Granulation

Our company has flat die granulator for organic fertilizer production. The machine has simple mechanism and reasonable design, and the granules are easy to dry with low water content. The granular materials processed by this machine have smooth surface, moderate hardness, and can well maintain the internal nutrients during processing.

The main structure of flat die pellet mill consists of feeding and discharging system, granulation system, transmission system and control system. Среди них, а flat die и extrusion rollers are this kind granulators’ main components.
А flat die granulator uses extrusion rollers and molds to extrude. It is used to granulate various organic substances after fermentation. Before granulating, you needn’t primarily dry and pulverize the raw materials. The columnar particles can be processed directly by batching.

It is mainly used for the granules processing of organic fertilizer and aquaculture processing industry.
It also can be applied chemical metallurgical materials granulation and powder materials like coal, carbon black, kaolin and stone powder.
Тем временем, it is the ideal granulation equipment for producing biomass energy pellets.

Reasonable structure to make machine run smoothly; lower energy consumption and production costs.
The pellets processed by the flat die extrusion granulator have smooth surface, uniform composition and neat shape.
Without the purchase of drying equipment; low investment cost in equipment and drying energy consumption.
Wide range of use; high finished products rate.

The requirements of materials is strict, and it is not easy to demold for some materials with high moisture content.

Double Roller Granulator for Powder

Extrusion method is the main method of granulation by compaction technology in powder processing industry currently. Our company has designed double roller extrusion granulator that has the advantages of advanced technology, compact structure and low energy consumption.

We can make pillow shape, semicircle shape, stick shape, pill shape, walnut shape, flat ball shape and square bar shape according to the customers’ needs.

It consists of electric control cabinet, conveying machine, feeding machine and hopper, broken studio and screening machine.
The double roller extrusion granulator adopts the dry extrusion process technology to extrude the powder with appropriate humidity into different shapes based on the shape and size of ball socket on the roller sheet.
After crushing, screening and getting the whole granules, then the granulator makes other powder extrusion and granulation again to make the material into the finished products that meet the requirements.

This equipment widely occurs in petrochemical, organic chemical, fine chemical, pharmaceutical, еда, feed, fertilizer and other fields.

Energy saving and consumption reduction.
Strong adaptability of materials.
The granulation products has uniform particle size, good particle strength and high granulation rate.

If there is no maintenance of equipment, the roller sheet will be seriously broken.

Powder granulation machine is a very promising device, which can not only improve the utilization rate of fertilizer, but also reduce the loss and pollution of fertilizer, which is of great significance to both agricultural production and environmental protection.

We suggest you should actively promote and apply these powder granulation machines to make a greater contribution to gain much benefits of social, economic and ecologic perspectives.
