The rotary drum granulator plays a crucial role in the NPK fertilizer production line, as it completes the granulation process of NPK compound fertilizer through an efficient wet granulation technology. The following are detailed granulation steps and principles:

Introduction to NPK Fertilizer

NPK fertilizer refers to a compound fertilizer containing three main nutrients: nitrogen (N), phosphorus (P), and potassium (K). It is widely used in crop cultivation to improve soil fertility and crop yield.

Working principle of rotary drum granulator

The core of a rotary drum granulator is a large drum shaped container that is tilted and slowly rotated, filled with the material to be granulated inside. This device utilizes a combination of centrifugal force and frictional force to promote the collision and agglomeration of materials during continuous rolling, ultimately forming uniform spherical particles.

Specific granulation steps

Raw material mixing: Firstly, accurately measure and thoroughly mix the pre proportioned basic fertilizer raw materials such as urea, diammonium phosphate (DAP), potassium chloride, etc. to ensure accurate distribution ratio.

Wetting and spraying: The mixed powdered raw materials are fed into a rotary drum granulator, while introducing an appropriate amount of water or other liquid binders to increase the adhesion between the materials.

Rolling forming: Under the slow rotation of the drum, the material begins to roll and gradually gather and increase, forming small balls with initial shape through the collision and aggregation between particles.

Growth and development: By adjusting the speed, angle, and time of the drum, the movement trajectory and dwell time of the material inside the drum are controlled, so that the small ball gradually grows to the required particle size.

Solidification: Heating may occur during the granulation process to help evaporate water and further enhance the stability of the particles; It is also possible to promote particle hardening by spraying a small amount of water vapor before discharging.

Cooling and screening: Finally, the particles are cooled down by a cooling tower and then separated into qualified products through a vibrating screen. Unqualified products are returned to the granulation area for reprocessing.

Key technical points

Material ratio: Ensure precise mixing of each component to achieve ideal fertilizer efficiency.

Adhesive selection: Reasonably select adhesives that promote particle formation without affecting fertilizer efficiency.

Controlling humidity: Moderate humidity is crucial for particle formation, as too high or too low can affect the quality of granulation.

Drum parameter tuning: including speed, tilt angle, filling rate, etc., directly affecting the size, strength, and appearance of particles.

Through careful design and precise regulation, the rotary drum granulation machine can produce uniform and sturdy NPK fertilizer particles, which not only improve the convenience of fertilizer storage and transportation, but also ensure the uniform application of nutrients, maximize fertilizer efficiency, and promote healthy crop growth.

The organic fertilizer granulator plays a key role in the process of treating manure in aquaculture farms, effectively achieving harmless treatment and resource utilization of manure. Below is a detailed introduction to how the organic fertilizer granulator achieves this goal:

1. Reduce environmental pollution

Biological deodorization: In the early stage of organic fertilizer granulation, microbial agents are added to accelerate fecal fermentation, which can effectively degrade harmful gases such as ammonia and hydrogen sulfide, reduce odors, and minimize negative impacts on the environment.

Solid liquid separation: using solid-liquid separation technology, the liquid part is used for sewage treatment, and the solid part is used as granulation raw material, avoiding the waste of water resources and reducing the possibility of water pollution.

2. Kill pathogens

High temperature fermentation: During the composting process, natural heating or a heating system is used to raise the internal temperature of the feces to above 70 ° C for several days, which can effectively kill most pathogens, parasite eggs, and other harmful microorganisms, ensuring the safety of the product.

3. Enhance nutritional value

Nutritional balance: By mixing different types of organic waste, such as cow manure, chicken manure, pig manure, and plant residues, the organic fertilizer processed by the granulator is nutritionally comprehensive, rich in essential plant elements such as nitrogen, phosphorus, and potassium, as well as various trace elements and active substances, which are more conducive to crop absorption.

Stabilization treatment: Organic fertilizers that have undergone sufficient fermentation release nutrients slowly and persistently, avoiding soil salinization problems that may arise from one-time large-scale fertilization.

4. Promote ecological cycle

Closed loop: The organic fertilizer granulator promotes the recycling of livestock and poultry manure, reduces dependence on external fertilizers, lowers the environmental pressure of agricultural production, and helps build a healthy ecosystem.

5. Economic value

Value added conversion: Feces, which were originally considered waste, are processed into high value-added products through granulators, increasing farmers’ sources of income.

Replacing traditional fertilizers: Organic fertilizers can completely or partially replace fertilizers in some cases, reducing fertilizer input and helping to lower costs in the long run.

Practical application

Many large farms at home and abroad have widely used organic fertilizer granulators to treat manure, such as ranches in the Netherlands, Germany, and other places. There are also many successful cases in China. For example, a certain agricultural technology enterprise in Jiangsu has adopted advanced organic fertilizer granulation technology and equipment to convert chicken manure from local farms into organic fertilizer. This not only solves the problem of environmental pollution, but also forms a virtuous cycle system of “planting and breeding integration”, achieving dual economic and ecological benefits.

In summary, the organic fertilizer granulator has made important contributions to the sustainable development of agriculture by not only treating manure from breeding farms, but also achieving harmless and resourceful treatment through a series of scientific methods.

In the production line of cow manure organic fertilizer, choosing the appropriate type of granulator directly affects the quality and production efficiency of the organic fertilizer. Considering the characteristics of cow manure, such as high moisture content and abundant cellulose, the following granulators are commonly used in the production of organic fertilizers from cow manure:

1. Drum granulator

The drum granulator is one of the most commonly used granulation equipment in the production of cow manure organic fertilizer. It naturally aggregates materials into balls under the combined effect of its own gravity and rotational force through a rotating drum and a suitable moist environment. The granulation process of this model is mild, especially suitable for processing high moisture raw materials such as fresh cow manure. In addition, by adjusting the angle and speed of the drum, the size and density of particles can be flexibly controlled.

2. Ring mold granulator

Ring mold granulator, also known as flat mold granulator, is suitable for processing various organic materials, including cow manure. Its working principle is to mix cow manure and other additives, and then extrude them from the micropores of the mold through high-pressure extrusion, forming a strip shape, which is then cut into particles. The particles formed by this method have a regular shape and high hardness, making them suitable for long-distance transportation and long-term storage.

3. Extrusion granulator

Squeezing granulator is suitable for processing materials containing a large amount of cellulose and high humidity, such as insufficiently dehydrated cow manure. This machine uses a powerful hydraulic system to forcefully squeeze materials out of the mold pores, forming dense particles that reduce the cost of later drying and can retain the active ingredients in cow manure to a certain extent.

4. Disc granulator

The disc granulator is another effective method, especially when dealing with small-scale production. Cow manure rolls on the inclined disc surface, and under the action of centrifugal force and its own gravity, the material gradually aggregates into spherical particles. This granulation method has good granulation effect, especially when the humidity of the raw materials is moderate.

Choose Suggestions

When choosing a cow manure organic fertilizer granulator, the following factors should be considered comprehensively:

Raw material characteristics: moisture content, fiber content, particle size, etc;

Capacity demand: expected daily or annual production;

Particle size: desired particle size and shape preference;

Budget constraints: consideration of equipment investment and operation and maintenance costs;

Environmental protection: whether low energy consumption and low emission solutions are needed;

Considering the specific characteristics of cow manure, it is recommended to give priority to drum granulators and ring mold granulators, both of which can effectively cope with the high moisture problem of cow manure while ensuring the granulation effect. Select the most suitable type of granulator based on the specific production scale and budget. In practice, it may be necessary to combine multiple granulation techniques and equipment to achieve optimal product quality and highest production efficiency.

Flat die granulator is a mechanical equipment widely used in the granulation process of organic fertilizers, feed, and other organic materials. Its design is based on the principle of pressure to form particles of specific shapes. The following is a detailed analysis of the working principle and granulation characteristics of the flat mold granulator:

working principle

The core components of a flat mold granulator are a set of rotating molds driven by a power device and parallel arranged pressure rollers. During operation, the raw materials are fed into the machine, and as the mold rotates and the pressure roller rolls, the raw materials are compressed and forcibly extruded through the aperture on the mold to form the desired shape. The specific steps are as follows:

Raw material preparation: Firstly, feed the pre treated organic materials (such as chicken manure, grains, grass powder, etc.) into the machine inlet.

Squeezing molding: The raw materials are subjected to tremendous pressure under the action of the mold and pressure roller, and the air between the raw materials is discharged, reducing the gaps between the molecules and resulting in a tight fit.

Cutting: When the material passing through the mold hole reaches a certain length, it is cut into independent particles by the cutting tool set at the outlet position.

Cooling and shaping: The newly extruded hot particles need to be cooled or blown to reduce temperature, in order to stabilize their shape and prevent softening and deformation.

Granulation characteristics

Pressure granulation: The flat die granulator relies on physical pressure rather than chemical reactions for granulation, which enables it to process various types of materials, including high fiber and low viscosity raw materials.

Diversity: By replacing different mold plates, particles with different diameters and lengths can be produced to meet diverse usage needs.

Easy to operate: Compared to other types of granulators, flat die granulators are more convenient to operate, have lower maintenance costs, and are suitable for small to medium-sized production scales.

Compact structure: Due to the lack of large power sources, the flat die granulator has a small volume and occupies little space, making it particularly suitable for production environments with limited space.

Energy saving and efficient: High operating efficiency, relatively low energy consumption, especially when dealing with raw materials with high humidity, it can still maintain good performance.

Widely applicable: not only suitable for the production of organic fertilizers, but also for the production of animal feed, biomass fuel pellets and other fields.

In short, the flat die granulator has become one of the important tools in industries such as organic fertilizers and feed due to its unique pressure granulation mechanism and wide applicability. Especially for small businesses and individual farmers, it is a cost-effective choice.
