fertilizer granulator Jul 16, 2024

Huaqiang fertilizer machine manufacturer supplies professional compound fertilizer equipment and designs NPK fertilizer manufacturing process. The scale of fertilizer production line can be from 2000 tons to 100000 tons per year.

The formula of organic-inorganic compound fertilizer is the same as that of inorganic fertilizer according to different soil and different crop formula. If the fermentation is sufficient and the formula is proper, the effect is better than that of inorganic fertilizer, and the cost is lower. It can also improve the living environment of plants and is green fertilizer.

Organic-inorganic compound fertilizer refers to a solid fertilizer that uses harmless treatment of organic matter (including high-temperature compost) and inorganic fertilizer (mainly nitrogen, phosphorus, and potassium fertilizer) as the main raw materials, and is mechanically processed through the organic fertilizer manufacturing process. This compound fertilizer is configured according to the nutrient characteristics of the soil and crops and the purpose of fertilizing the soil, and has the characteristics of nutrient balance.

The horizontal mixer is used in the mixing stage of NPK fertilizer manufacturing process to fully mix different kinds of nutrients to prepare for the granulation of rotary drum granulator.

Performance characteristics of horizontal mixer

The rotation speed of the shaft driven by the reducer and the structure of the blade will weaken the gravity of the material. With the lack of gravity, the difference of particle size and specific gravity of the material is ignored in the mixing process.

The intense stirring movement of horizontal mixer shortens the mixing time, which is faster and more efficient. Even if the material has the difference of specific gravity and particle size, it can achieve good mixing effect under the rapid and violent tossing of staggered mixing blades. In the manufacturing of NPK fertilizer, the raw materials need to be fully mixed. The mixer has high mixing uniformity and less residue. The horizontal mixer is suitable for mixing more than two kinds of fertilizers, additives and premix.

The influence of granulation process of pig manure organic fertilizer granulator on product quality

fertilizer granulator Jul 16, 2024

The impact of the granulation process of the pig manure organic fertilizer granulator on product quality is mainly reflected in the following aspects:

Particle size distribution:

Different granulation processes can affect the particle size distribution of the final product. Wet granulation usually results in a relatively uniform particle size distribution, while dry granulation may produce significant particle size differences.

Particle strength:

Wet granulation, by adding water or other liquids as binders, can increase the strength and hardness of the particles, making them more suitable for storage and transportation.

The particle strength of dry granulation is relatively low, but the energy consumption during the production process is low.

Moisture content:

Wet granulation can increase the moisture content of the product, which may affect storage and subsequent processing.

Dry granulation has a lower moisture content, but may require additional drying processes.

Organic matter content:

The granulation process may affect the conversion efficiency of organic matter in pig manure, thereby affecting the fertilizer efficiency of the product.

Wet granulation facilitates microbial activity and may promote the conversion of organic matter.

Environmental impact:

Wet granulation may generate wastewater and exhaust gas, and appropriate treatment measures are needed to reduce environmental pollution.

Dry granulation has a relatively small impact on the environment.

Production efficiency:

The production efficiency of wet granulation is usually higher than that of dry granulation because its drying and granulation processes can be carried out continuously.

The production efficiency of dry granulation is relatively low, but the energy consumption is also low.

Cost:

The production cost of wet granulation is relatively high because it requires additional energy and materials to regulate humidity.

The production cost of dry granulation is lower, but the product quality may not be as good as wet granulation.

Based on the characteristics of pig manure and the intended use of the final product, a suitable organic fertilizer granulation process can be selected to optimize product quality. For example, if high-strength particles are needed, wet granulation can be chosen; If low-cost production is required, dry granulation can be chosen. At the same time, appropriate measures should be taken to reduce the environmental impact during the production of fertilizers by organic fertilizer granulators, taking into account the requirements of environmental protection and sustainable development.

Granulation process and working environment of pig manure organic fertilizer granulator

fertilizer granulator Jul 12, 2024

The granulation process of pig manure organic fertilizer granulator is mainly divided into two types: wet granulation and dry granulation.

Wet granulation:

Wet granulation refers to adding a certain amount of water or other liquid during the granulation process to achieve a certain humidity condition for pig manure raw materials, and then extruding them into granules through mechanical force.

The advantage of wet granulation is that it can produce uniform and smooth particles, and the particles have high strength and are not easily broken.

The disadvantage is that it requires more energy to heat and dry wet particles, and the production process may generate wastewater and exhaust gas.

Dry granulation:

Dry granulation refers to the process of directly utilizing the moisture and binder of pig manure raw materials through mechanical force without adding additional water.

The advantages of dry granulation are low energy consumption, simple production process, and no generation of wastewater and exhaust gas.

The disadvantage is that the quality of the particles may not be as uniform as wet granulation, and the strength of the particles is relatively low, making them easy to break.

The working temperature of the pig manure organic fertilizer granulator usually depends on various factors, including the properties of the raw materials, the required final product characteristics, and the production process. In practical operation, the working temperature of the pig manure organic fertilizer granulator is generally between 50 ℃ and 100 ℃. Within this temperature range, organic matter in pig manure is more easily decomposed by microorganisms, which is beneficial for the activity of the binder and thus facilitates the smooth granulation process.

However, the specific working temperature still needs to be adjusted according to the actual production situation. For example, if the moisture content in the raw material is high, it may be necessary to increase the working temperature to accelerate the evaporation of moisture; On the contrary, if the moisture content in the raw material is low, it may be necessary to lower the working temperature to prevent particle hardening caused by rapid evaporation of moisture. In addition, excessively high operating temperatures may lead to excessive wear and tear of the equipment, while excessively low operating temperatures may affect the granulation effect.

Therefore, in practical operation, the working temperature of the organic fertilizer granulator should be reasonably set according to the specific properties of pig manure and production process requirements to ensure the stability of the production process and the reliability of product quality. At the same time, close attention should be paid to the operating status of the equipment, and process parameters should be adjusted in a timely manner to adapt to changes in raw materials and environmental conditions.

Selecting appropriate equipment for fertilizer production lines to reduce equipment losses

fertilizer granulator Jul 12, 2024

NPK compound fertilizer production line needs a lot of supporting equipment to complete the whole granulation production task when processing fertilizer. In these many supporting equipment, there is a mixing equipment, fertilizer mixer for mixing materials.

Horizontal mixer for intermittent operation, it is suitable for rotary drum granulator mixing operation. General fertilizer production should be equipped with two or more sets to keep the production flexible to meet the market demand.

Fertilizer mixer is the supporting production equipment of the whole compound fertilizer production equipment. We can calculate the specific model and specification according to the output of the fertilizer production line.

the impact of the working temperature of the pig manure organic fertilizer granulator on product quality

fertilizer granulator Jul 12, 2024

The working temperature of the pig manure organic fertilizer granulator has a significant impact on product quality, directly affecting the physical and chemical properties of the final product, as well as production efficiency and energy consumption.

Influence of physical properties:

Low working temperature may result in ineffective evaporation of moisture in pig manure raw materials, causing the particles produced by the organic fertilizer granulator to be too wet, affecting storage and transportation.

Excessive working temperature may cause the surface of particles to harden excessively, while maintaining a high level of moisture inside. Such particles are prone to cracking or deformation during subsequent drying and storage processes.

The appropriate working temperature can ensure that the particles have moderate hardness and strength, which is convenient for subsequent processing and use.

Chemical properties influence:

High temperatures may accelerate the thermal decomposition of organic matter in pig manure, alter its chemical structure, and affect the fertilizer composition of the product.

High temperatures may also promote the generation of certain harmful substances, such as volatile organic compounds like ammonia, which may cause environmental pollution.

Production efficiency and energy consumption:

A higher working temperature usually means a faster rate of water evaporation, which can improve production efficiency but also increase energy consumption.

If the working temperature is too high, it may cause excessive wear and tear of the equipment, shorten its service life, and increase maintenance costs.

Microbial activity:

Pig manure contains a large number of microorganisms, and a suitable working temperature is conducive to microbial activity, fermentation, and organic matter conversion in pig manure.

If the working temperature is too high or too low, it may inhibit the activity of microorganisms, affecting the fermentation effect and subsequent fertilizer performance of pig manure.

Therefore, when operating the pig manure organic fertilizer granulator, it is necessary to strictly control the working temperature to ensure that the produced organic fertilizer products have good physical and chemical properties, while ensuring the efficiency and environmental protection of the production process. Usually, this requires experimental determination of the optimal operating temperature range and fine-tuning in actual production to adapt to changes in seasons and raw material conditions.

Issues to be noted in maintaining the processing equipment of organic fertilizer production lines

fertilizer granulator Jul 12, 2024

The organic fertilizer production line includes disc granulator, drum screening machine, semi wet material grinder, horizontal mixer, organic fertilizer dryer, fermentation compost turning machine, cooler, packaging equipment, etc. These machines are professional equipment for the production of organic fertilizer.

These fertilizer equipments are large in size, not low in price, and can be used for a long time, so we need to maintain these organic fertilizer equipments well at ordinary times. The following is a brief introduction to the six points for attention of organic fertilizer production line equipment maintenance:

1. Prevent the engine from overheating. Long time use should pay attention to timely shutdown, try to choose a cool place, and open the hood for ventilation and heat dissipation.

2. Prevent lubricating oil from oxidation and deterioration. The summer lubricating oil should be replaced in the crankcase and gearbox. The quantity and quality of lubricating oil should be checked frequently and replaced in time.

3. Protect the machine from excessive sun exposure. Whether it is the manufacturing of NPK fertilizer or the production of organic fertilizer, the paint on the fertilizer equipment should be bright and clean to protect the machine from rusting. Long term exposure will change color and wrinkle. Ordinary protection, such as cleaning and waxing, has some effects, but it is difficult to achieve long-term effect.

4. Prevent the mixture from being too rich. In order to reduce the oil supply and prevent the danger caused by too rich gas mixture, the metering hole should be reduced, the connecting position of acceleration device and throttle rocker arm should be adjusted, and the oil level should be reduced appropriately.

5. Preventing air resistance. To prevent air resistance, the gasoline pump can be wrapped with a damp cloth to cool down.

6. Prevent excessive evaporation of gasoline and water. At high temperatures, the evaporation of oil and water will speed up. At this time, you need to check at any time. Once you find any abnormalities or irregularities, you must add and adjust in time.

How to ferment sheep manure into organic fertilizer using organic fertilizer equipment

fertilizer granulator Jul 12, 2024

The process of fermenting sheep manure into organic fertilizer by organic fertilizer equipment mainly includes the following key steps:

Raw material pretreatment:

Raw material collection: Collect fresh sheep manure to ensure no pollution and avoid impurities such as plastic and metal.

Raw material crushing: Use a crusher to crush sheep manure to increase its surface area and promote microbial decomposition.

Preparation before fermentation:

Adjusting moisture: Based on the initial moisture content of sheep manure, add water appropriately to achieve a level suitable for microbial activity, usually maintaining a moisture content of 50% -60%.

Adjusting the carbon to nitrogen ratio: By adding carbon source substances such as straw and sawdust, the carbon to nitrogen ratio of sheep manure can be adjusted. The recommended carbon to nitrogen ratio is generally 25:1 to 30:1.

Microbial inoculation (optional): To accelerate the fermentation process, specific microbial agents can be added, which can promote the decomposition and transformation of organic matter.

Fermentation process:

Composting production: The processed sheep manure is piled up in piles, and the size of the compost can be adjusted according to the actual situation, but sufficient space should be ensured for flipping.

Temperature control: Keep the temperature of compost at 50-70 ℃, which is the temperature range for vigorous microbial activity.

Regular flipping: Regularly (usually every 2-3 days) flipping is carried out to maintain the oxygen supply inside the compost and promote the uniform distribution of microorganisms.

Monitoring the fermentation process: Observing the color, odor, and temperature changes of compost are important indicators for judging the fermentation process.

After ripening and screening:

Post ripening: When the temperature of the compost begins to decrease and remains below 50 ℃, it indicates that the fermentation process is nearing its end.

Screening: Use a screening machine to remove incompletely decomposed large blocks of material and impurities, and obtain relatively pure organic fertilizer.

Packaging and storage:

Packaging: Use an organic fertilizer packaging machine to package the screened organic fertilizer, using breathable packaging materials such as woven bags.

Storage: Store in a cool and dry place, avoiding direct sunlight and soaking in rainwater to maintain its quality.

quality testing:

Conduct quality inspections on finished organic fertilizers, including nutrient content, pH value, heavy metal content, etc., to ensure they meet agricultural usage standards.

The organic fertilizer equipment achieves efficient conversion of sheep manure into organic fertilizer through automated control and precise process flow, not only improving production efficiency but also ensuring the stability of product quality. In practical operation, appropriate adjustments and optimizations should be made based on the specific characteristics of raw materials, environmental conditions, and production needs.

What is the granulation process of the pig manure organic fertilizer granulator

fertilizer granulator Jul 12, 2024

The workflow of a pig manure organic fertilizer granulator usually includes the following steps:

Raw material preparation:

Firstly, it is necessary to collect pig manure and perform preliminary processing such as crushing, screening, and mixing to ensure the homogeneity and suitability of the raw materials.

Raw material pretreatment:

Pig manure is crushed by an organic fertilizer crusher to achieve moderate particle size, which facilitates the subsequent granulation process.

As needed, an appropriate amount of water and adhesive can be added to adjust the moisture content and bonding properties of the raw materials.

Raw material transportation:

The crushed and pretreated pig manure is fed into the hopper of the organic fertilizer granulator through a conveyor belt.
