The application of roller extrusion granulator in organic fertilizer production has demonstrated a series of significant advantages, which not only improve production efficiency, but also ensure product quality and reduce production costs. The following are the main advantages of using a roller extrusion granulator to produce organic fertilizers:

Efficient granulation: The roller extrusion granulator squeezes materials through two sets of relatively rotating rollers, which can quickly form regular particles with high granulation efficiency, suitable for continuous production, and improve productivity.

High particle strength: By precisely controlling the pressure between the rollers, particles with high mechanical strength can be produced. These particles are not easily broken during packaging, transportation, and storage, reducing dust and increasing the market value of fertilizers.

Low energy consumption: Compared with traditional wet granulation or rotary drum granulation, the energy consumption of the roller extrusion granulator is lower. It mainly utilizes the self weight of materials and mechanical extrusion force, reducing dependence on thermal energy and lowering energy consumption and production costs.

Easy to operate: The roller extrusion granulator has a simple structure, is easy to operate and maintain, has a high degree of automation, reduces manual intervention, and improves the stability of the production process.

Good environmental friendliness: The granulation process generates less dust and exhaust gas, which helps reduce environmental pollution and meets the requirements of modern green production. In addition, the efficient utilization of organic materials also reduces the generation of waste.

Wide applicability: It can handle various organic materials, including livestock manure, crop waste, urban organic waste, as well as organic-inorganic mixed materials, with strong adaptability to meet the granulation needs of different raw materials.

Controllable particle shape and size: By adjusting the shape and size of the rollers, particles of different sizes and shapes can be produced to meet the diverse needs of the market for fertilizer particles.

Reduce drying demand: The particles produced by the roller extrusion granulator have a lower moisture content, reducing the need for subsequent drying treatment and lowering production costs.

Reasonable raw material pretreatment (such as crushing, mixing, adjusting humidity) and appropriate equipment maintenance are key to ensuring production efficiency and product quality when using a roller extrusion granulator to produce organic fertilizers. In addition, according to specific production needs, auxiliary facilities such as raw material processing equipment, screening equipment, packaging equipment, etc. may need to be configured to form a complete organic fertilizer production line.

The cow manure organic fertilizer granulator is a key equipment used in organic fertilizer production lines to process organic materials such as cow manure into granular fertilizers. The working principle varies depending on the type of granulator, and can be mainly divided into the following categories:

Disc granulator:

Working principle: The raw materials are fed into the rotating disc of the disc granulator, which tilts at a certain angle and rotates at a certain speed. The raw material forms a thin film at the edge of the disc under the action of centrifugal force and gravity. During the rotation process, the raw material particles gradually increase through mutual collision and adhesion, forming spherical particles. Meanwhile, the disc granulator is usually equipped with a water spray device, which can control the humidity during the granulation process to facilitate the formation of particles.

Roll squeezing granulator:

Working principle: After pre-treatment, the raw materials are fed between two relatively rotating rollers. The pressure between the rollers compresses and extrudes the raw material, forming a continuous strip of material. Strip shaped materials are cut into particles of the desired size using a cutting knife. The roller extrusion granulator is suitable for raw materials with low humidity. By adjusting the pressure and spacing of the rollers, the size and shape of the particles can be controlled.

Ring mold granulator (also known as extrusion granulator):

Working principle: After pre-treatment, the raw materials are sent between the ring mold and the pressure roller of the ring mold granulator. There are multiple holes on the ring mold, and the pressure roller applies high pressure to the raw material, forcing it to pass through the holes on the ring mold to form a continuous strip of material, which is then cut into particles by a cutting knife. The ring mold granulator is suitable for various humidity and viscosity raw materials. By adjusting the ring mold aperture and roller pressure, the particle size and density can be controlled.

Drum granulator:

Working principle: The raw materials are subjected to mechanical force and moisture in the drum. Through the rotation of the drum and the design of its internal structure, the raw materials continuously roll, collide, and bond in the drum, gradually forming the required particles. The drum granulator is suitable for processing raw materials with high humidity. By adjusting the speed and internal structure of the drum, the size and shape of the particles can be controlled.

The cow manure organic fertilizer granulator processes raw materials into granules through different working principles, which not only improves the storage and transportation efficiency of fertilizers, but also enhances the application effect of fertilizers. It is an indispensable equipment in organic fertilizer production. When choosing a granulator, the most suitable type should be selected based on the characteristics of the raw materials, the expected particle size and shape, and production requirements.

Based on the above considerations, combined with specific production needs and conditions, it is possible to more accurately select the crusher suitable for the NPK fertilizer production line, ensuring the efficient and stable operation of the production line. In the decision-making process, it is recommended to consult industry experts or equipment suppliers for professional advice and technical support.

The investment cost of NPK fertilizer production line varies greatly depending on multiple factors, including the scale of the production line, degree of automation, equipment selection, raw material processing requirements, geographical location, construction costs, and whether additional facilities (such as warehouses, laboratories, etc.) are needed. The following are some of the main factors that affect the investment cost of NPK fertilizer production lines and their possible ranges, but please note that these are for reference only and the actual cost may vary depending on the specific project:

NPK fertilizer production line scale: The investment for small-scale production lines (with an annual production capacity of less than 10000 tons) may range from tens of thousands to several million RMB; The investment for medium-sized production lines (with an annual capacity of 10000 to 50000 tons) may range from several million to tens of millions of RMB; The investment in large-scale production lines (with an annual production capacity of over 50000 tons) may exceed tens of millions or even hundreds of millions of RMB.

Equipment selection: High end and highly automated equipment have higher prices, but lower long-term operating and maintenance costs. For example, a fully automated granulator may cost several times more than a traditional manually controlled granulator.

Raw material processing: If raw materials require pre-treatment (such as drying, crushing), additional equipment and costs may be required. The cost of pre-processing equipment may range from tens of thousands to hundreds of thousands of RMB.

Geographical location: The cost of building production lines varies greatly in different countries or regions, including land costs, construction costs, labor costs, transportation costs, etc. For example, the cost of building production lines in developed countries may be much higher than in developing countries.

Auxiliary facilities: including raw material warehouse, finished product warehouse, laboratory, office area, etc. The construction and operation costs of these facilities also need to be included in the total investment.

Installation and commissioning: The installation and commissioning of new equipment also require a certain cost, which may account for 5% -10% of the total investment.

Environmental and safety measures: Equipment and facilities that meet environmental and safety standards may incur additional costs, especially in strictly regulated areas.

Working capital: In addition to fixed investments, it is also necessary to consider the initial working capital requirements for purchasing raw materials, paying salaries, maintaining equipment, etc.To obtain a more accurate estimate of investment costs, it is recommended to consult professional equipment suppliers, engineering design companies, or industry consultants who can provide detailed cost analysis and investment return forecasts based on your specific needs and conditions. When planning an NPK fertilizer production line, in addition to considering initial investment costs, factors such as operating costs, market potential, and policy environment should also be evaluated to ensure the feasibility and long-term profitability of the project.

In order to improve the pelletizing rate of the rotary drum granulator, it is necessary to configure the material structure reasonably in order to improve the pelletizing rate of the rotary drum granulator.

Material structure mainly refers to the following aspects.

1. Reasonable matching of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: raw materials of 100-60 mesh account for about 30% – 40%, raw materials of 60 mesh to diameter of 1.00 mm account for about 35%, and small particles with a diameter of 1.00-2.00 mm account for about 25% – 30%. The higher the fineness of the material, the better the viscosity, and the higher the surface finish after granulation. However, in the production process, the use of super proportion of high fineness materials can easily lead to the problems of too large particles, irregular particles and material sticking to the wall.

2. Reasonable collocation of cohesive materials and dispersive materials. In the production process formula, the proportion of viscous raw materials is high, which is easy to form balls, the proportion of dispersive raw materials is high, and there are more fine powders. In the conventional formula of fertilizer production line, the proportion of viscous raw material for low concentration compound fertilizer is 45% – 50%, and that of high concentration compound fertilizer is 35% – 40%. At the same time, it should be combined with material fineness. If the matching is not good, there will be no fine powder, no particles, particles are not round, easy to get big ball and so on.

3. Chemical reactions between materials should be considered in formulation. After the formulation of some materials, free water will be precipitated during the production process, which will cause the liquid phase of the material to exceed the standard and cannot be produced normally. Some raw materials will greatly reduce the critical relative humidity of the mixture after matching. During the production process, due to the large amount of moisture absorption Unable to produce normally. Therefore, the chemical reaction between the materials must be considered when formulating to achieve a reasonable match between the materials.

4. The comprehensive moisture content of materials after mixing. The water content of raw materials directly affects the granulation. Even if steam and water are not added in the production of some materials after mixing, they can not be produced normally. Therefore, low moisture content of materials in organic fertilizer production line is conducive to the addition of steam in granulation. This is beneficial to improve the temperature and viscosity of the materials, thus improving the compatibility and pelletizing rate of the materials.
