fertilizer production line

Before using organic fertilizer equipment, the following preparations need to be made:

Site preparation:

Choose a suitable site to ensure sufficient space for the installation and operation of organic fertilizer equipment, and the site should be flat, solid, and have a good drainage system.

Clean up the site, remove weeds and obstacles, and ensure that there are no hard objects that may damage the equipment.

Equipment inspection:

Carefully inspect the newly purchased organic fertilizer equipment to ensure that all components are intact and meet factory standards.

For equipment that has already been used, conduct a comprehensive maintenance inspection, including fastening of fasteners, inspection of electrical circuits, replacement of vulnerable parts, etc.

Installation and debugging:

Install according to the equipment manual, ensuring that all components are correctly installed in place, all connecting parts are well sealed, and there is no air or liquid leakage.

After installation, carry out debugging of the organic fertilizer equipment to ensure smooth operation and that all parameters meet the design requirements.

Raw material preparation:

According to production needs, prepare an appropriate amount of raw materials, such as animal manure, crop straw, etc., to ensure that the quality and humidity of the raw materials meet fermentation requirements.

Pre treat the raw materials, such as crushing, mixing, adjusting moisture, etc., to meet the processing requirements of the equipment.

Security training:

Provide safety training to operators to ensure they are familiar with the equipment’s operating procedures, safety measures, and emergency response methods.

Emphasize the importance of personal protection, such as wearing protective clothing, gloves, masks, etc.

Environmental assessment:

Assess the potential impact of the production process on the surrounding environment, such as odor diffusion, sewage discharge, etc., and develop corresponding environmental protection measures.

Regulatory compliance:

Understand and comply with local laws and regulations related to organic fertilizer production, ensuring that the production process is legal and compliant.

Record keeping:

Establish a production record system to record information such as raw material procurement, equipment maintenance, production process, and product quality testing for traceability and quality control.

Through the above preparation work, the smooth operation of organic fertilizer equipment can be ensured, production efficiency can be improved, and the safety and environmental protection of the production process can be guaranteed.

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.

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.

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.

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.

Granulation molding:

Pig manure flows from the hopper into the working chamber of the organic fertilizer granulator, and under the compression of the rotating spindle and mold, it forms regular particles.

The temperature and pressure inside the granulator need to be strictly controlled to ensure the quality and forming effect of the particles.

Particle screening:

The formed particles are sieved through a screening system to remove unformed or oversized particles.

Qualified products after screening are collected, while unqualified products can be recycled and reprocessed.

Cooling and drying:

The newly formed wet particles need to be cooled and dried to reduce their moisture content and facilitate subsequent packaging and storage.

Packaging and Storage:

The dried particles are packaged through an automatic packaging line and stored in a dry and ventilated warehouse, waiting for sale or use.

Quality Control:

Throughout the entire workflow, regular quality inspections of raw materials and finished products are required to ensure that the products meet relevant standards and customer requirements.

Equipment maintenance:

Regularly maintain and upkeep the organic fertilizer granulator and its auxiliary equipment to ensure the normal operation and service life of the equipment.

Through the above workflow, the pig manure organic fertilizer granulator can convert pig manure into organic fertilizer particles with a certain shape and particle size, providing high-quality organic fertilizer for agricultural production.

Mushroom residue is the product of mushroom planting. There is no reasonable way to use the residue in many mushroom planting bases, which leads to waste. Now NPK fertilizer granulator manufacturer will introduce how to recycle through mushroom residue organic fertilizer production line.

Mushroom residue can be returned to farmland after recycling, and there is no place for disposal of the former waste mushroom residue. Through the treatment of organic fertilizer production process, the substrate nutrient soil can be fermented into a substrate, and the price per ton can be sold to a higher price. So how can waste mushroom residue be made into matrix nutrient soil. The method of making mushroom residue into substrate is introduced below.

Mushroom dregs are usually used as mushroom culture materials with cottonseed shell as the main component. They are eliminated after being planted and can be used as soilless culture media. The unit weight is 240 kg / M 3. Because there are a large number of mycelium in the bag, it can be twisted into a block, which can be irrigated in large amount, and then covered with plastic film. When the mycelium is rotted, the mushroom residue will be naturally broken.

If you are eager to use it, you can also use tools to mechanically break it and then screen it. After screening, with other materials, add the fermentation agent; the crushed or cut-off main materials are pre soaked or washed and pre wetted, and the water content is adjusted to 60-70%, pH value is about 8. Mixed reactor. Use thermometer to observe the temperature. When the temperature reaches 60 ℃, use organic fertilizer equipment to turn over the pile. The fermentation can be completed by 2-3 times in a row. The fermented fertilizer can be used to grow vegetables, or it can be processed again by the organic fertilizer manufacturing process and then sold in bags.

The waste mushroom dregs are very rich in nutrients, which can be used to make flower and nursery stock matrix as mentioned above, and can also be used as auxiliary materials for the treatment of livestock and poultry manure and fermentation to make organic fertilizer. The profit can reach 20% of the total mushroom output. Modern agriculture, we must choose more high-tech technology to help your planting!

The pig manure organic fertilizer granulator usually adopts extrusion granulation technology, and its working principle is based on physical changes, mainly including the following steps:

Feeding system:

Pig manure is evenly fed into the working chamber of the organic fertilizer granulator through the feeding system.

The feeding system usually includes a storage bin and a conveying device to ensure continuous supply of pig manure to the interior of the granulator.

High pressure environment:

When pig manure enters the working chamber of the organic fertilizer granulator, it is subjected to high pressure.

There are one or more rotating spindles inside the granulator, which are equipped with a series of molds or pressure rollers.

Pig manure is gradually squeezed into granules by the rotation of the main shaft and the compression of the mold.

Granulation process:

Under the action of high pressure and friction, the surface of pig manure particles begins to harden, and as the material moves in the mold, the particles gradually increase in size.

Meanwhile, due to the moisture and adhesive inside pig manure, the binding force between particles is enhanced, forming a stable structure.

Molding and demolding:

When the particles reach a certain size and hardness, they will detach from the mold and form a complete granulation product.

These particles are then discharged from the granulator through the discharge port and enter the next processing stage.

Drying and cooling:

Freshly granulated particles may contain high levels of moisture and require a drying process to reduce their moisture content for better storage and transportation.

The dried particles may still need to be cooled to prevent quality issues caused by excessive temperature.

Screening and Grading:

Finally, the pelletized product is screened using screening equipment to remove unqualified particles and obtain organic fertilizer products that meet the standards.

The pig manure organic fertilizer granulator converts pig manure, a low value waste, into organic fertilizer particles with a certain shape and particle size through the above working principle, thereby improving its market value and utilization effect.

As the necessary equipment for manufacturing of npk fertilizer and organic fertilizer, the advantages of drum screening machine are high efficiency, low noise and small amount of dust. And normal use and maintenance, the service life of the screening machine is also very long, easy to clean and replace the screen.

Preparation before commissioning of screening machine:

1. After the screening machine is installed and inspected to be qualified, the test run can be carried out. Before the test run, the parts of the organic fertilizer production line shall be inspected in detail to see whether they are installed correctly as shown in the drawing, whether the fasteners are firm, and whether there are obstacles around the screen body that hinder the operation of the roller screen

2. Place the rectangular access door in the open position, and rotate the screening cylinder through manual turning to observe whether the comb type screen cleaning mechanism is jammed or friction. If it is, it can be adjusted by adjusting the bolt

3. Check the bearing pedestal and gearbox for good lubrication and proper oil level

4. The power connector should be firm and reliable, with good insulation and correct groundingPrecautions for feeding of screening machine of fertilizer production line:

1. When the organic fertilizer equipment screening machine is running smoothly, start the feeding and discharging equipment, and conduct the feeding trial.

2. Close the sealing isolation cover after normal discharge (the sealing isolation cover should always be in the closed position during normal operation).

3. The screening machine screens the particles formed by the rotary drum granulator, and checks the particle size of the discharged material, whether there is leakage and dust.

4. After running for half an hour, carefully check all parts and deal with problems in time.

5. During the work process, the operation should be checked frequently. If the operation is found to be abnormal or abnormal noise, it should be shut down and checked in time to find out the reason and eliminate the fault.

NPK fertilizer manufacturing process of rotary drum granulator

1.In the solid granulation process of rotary drum granulator, urea, ammonium chloride, ammonium sulfate, potassium chloride and other single base fertilizers are used as raw materials and mixed in a certain proportion (mainly determined by the local market demand and soil testing results).

2.Then evenly mix the distributed raw materials with a fertilizer mixer, and crush them to a certain fineness. Next is the main necessary step – granulation, here you need a drum granulator.

3.The material is sent to the drum granulator by belt conveyor, and agglomerates and forms particles through a series of humidification and heating processes.

4.The particles here are only semi-finished products. They need further processing, including drying, screening, cooling and packaging. After all these procedures, high quality compound fertilizer products can be obtained.
