What are the granulation methods of fertilizer granulators?

fertilizer granulator Oct 10, 2023

The difference between granulators is to choose the appropriate granulation method based on the usage requirements of the material. What are the granulation methods for fertilizers? How does a fertilizer granulator granulate.

The granulator is just a general term, with subdivisions and branches below it. Mainly divided into two categories: dry method and wet method:

1. Dry fertilizer granulation:

It mainly refers to products with relatively low material moisture, generally with a zero threshold of moisture below 10%. (There are also very few materials that can reach 16%, such as some materials that only carry crystalline water.) Dry granulation produces mostly irregular particles (such as common granular potassium fertilizer) or more commonly, similar shapes like small crushed stones.

The roller extrusion granulator belongs to the dry granulation process, without the need for drying process, with high granulation density, good fertilizer efficiency, and full organic matter content; It also saves the money for purchasing dryers and cooling machines, and there is no need to burn coal in the later stage, thus saving a significant portion of the funds. However, the granulation process of the squeezing granulator belongs to a flat circular shape, which is prone to jamming during machine sowing of crops in the field, and its fluidity is not very good. Therefore, if this granulation process is used carefully for organic fertilizer produced by machine sowing farmers, it is recommended to use composite fertilizer or compound fertilizer.

Compared to wet granulation, dry granulation has lower energy consumption and is more environmentally friendly. It does not require drying, does not add water or binders, so it does not change the material properties; These are also several advantages that differentiate dry granulation from wet granulation. More suitable for industrial mass production.

2. Wet fertilizer granulation:

There are also many types of equipment and methods in wet granulation for materials with a moisture content of over 20%. For example, the methods of disc granulation, drum granulation, and screw granulation have been continued many years ago, and have made significant progress through continuous improvement in the usage environment and processing requirements of different materials. For example, in recent years, organic fertilizer granulation has become popular, with particle sizes ranging from 1mm to 6mm. These methods are commonly used.

The stock conversion granulator is a process that has always been used for compound fertilizer granulation, and can also be used to produce organic fertilizers. However, the granulation rate is relatively low. If producing organic and inorganic organic fertilizers, this process can be chosen.

The disc granulator is a relatively traditional process, and I personally highly recommend this type of granulator. It produces smooth particles and sells well, but the only drawback is its low density; At present, people are pursuing new and innovative methods of granulation, so the number of users is gradually decreasing (universal).

The stirring tooth granulator is a product that is widely favored by customers. This process has high yield and smooth processing. If an organic fertilizer rounding machine is added, the granulation can be comparable to disc granulator. However, it is necessary to purchase a drying machine and a cooling machine, as the entire set of equipment for this process of organic fertilizer is expensive.

Chemical sludge dryer can dry materials with 90% water content to finished products in one go. In response to the characteristic of easy agglomeration during the sludge drying process, the material plate structure of the general single channel dryer has been changed, and a combined self-cleaning device has been adopted, greatly expanding the application range of the single channel dryer. It can not only dry various types of sludge, but also various high viscosity materials.

1. Before installation, check whether all components are intact and clean the interior.

2. After installation in place and before commissioning, check whether the bearing seat has been filled with lubricating grease, or add proper amount of lubricating grease. Generally, No. 2 molybdenum disulfide compound calcium base grease or other suitable grease resistant to high temperature shall be used.

3. Before installing the rotary joint, it is necessary to carefully read the “User Manual” of the rotary joint and install it correctly to prevent damage to the sealing gasket.

4. Pressure gauges and pressure stabilizing devices need to be installed on the inlet pipeline of heating or cooling media. A safety valve must be installed before the inlet to prevent equipment from operating under overpressure. The temperature of the heating medium must not exceed the rated operating temperature.

5. When installing a rotary joint with a single end configuration at the end of the shaft, attention should be paid to the fact that the surface of the nozzle end that extends into its inner cavity within 200mm should be smooth and free of holes, rust, slag, and scars, meeting the sealing requirements for heating (or cooling) media, and the size should be appropriate. Just like the double end installation rotary joint, the entire machine can only be debugged after pressure testing without leakage.

6. Inspect and debug gear or chain drives to ensure they meet mechanical transmission requirements.

7. Conduct safety checks on electric motors and appliances. Touch the power switch of the motor to ensure that there is no jamming on the motor and transmission components, and ensure that the rotation of the main shaft is correct (the blade should be pointed forward when rotating).

8. Start the motor and let the equipment run without load. The operation should be smooth and there should be no abnormal noise. For those with speed regulation devices, speed regulation should be carried out within an adjustable range, and acceleration should be carried out slowly to check whether the speed regulation characteristics meet the requirements. The no-load operation shall not be less than 30 minutes.

9. Gradually heat or cool, observe the operation, and ensure that the heat or cold source meets the usage parameters. Equipment with cooling protection devices must open the cooling water valve before steam is supplied. Gradually add materials, observe and check the drying condition of the materials, and continuously adjust the feeding amount, heat (cold) source amount, discharge amount, and speed as needed. Once the design requirements are met, the materials can be put into normal operation.

Organic fertilizer equipment is a powerful assistant in current production, and it will inevitably cause wear and tear in actual operation. Therefore, it is more important to use and maintain the equipment correctly to ensure the normal use of organic fertilizer. Below is an introduction to how to avoid malfunctions during the use of organic fertilizer production equipment.

Daily maintenance of organic fertilizer production equipment

1. Keep the workplace clean. After the completion of each organic fertilizer production equipment, the residual rubber sand inside and outside the granulation leaves and pots should be thoroughly removed. Scattered or splashed rubber sand and flying objects on organic fertilizer equipment should be cleaned up. The machine of organic fertilizer equipment should be exposed to the external processing surface, wiped clean, coated with anti rust meat paint, and applied with corresponding protective layer. Cover to prevent dust from invading again.

2. Organic fertilizer production equipment does not have external filling holes. Gears and worm gears are lubricated with organic fertilizer equipment specific grease. The upper and lower gears should be added with three in one butter every quarter. When refueling, the movable gearbox cover and the gearbox gear cover can be opened separately. Lubricating oil should drip into the sliding surface between the support gearbox and the support hinge. The worm gearbox and bearings are shipped with sufficient transmission grease, but the gearbox machine should be thoroughly cleaned once a year and all protective lubricants should be replaced.

3. Always pay attention to the operation of organic fertilizer production equipment. There should be no serious abnormal noise or metal friction noise. If any abnormalities are found, the machine should be immediately shut down for inspection. Only use after troubleshooting. Unable to check the corresponding reason, unable to start the machine. If there is a metal friction sound, you can first check the gap between the organic fertilizer equipment.

4. Regularly check the standard clearance between organic fertilizer production equipment.

5. When repairing organic fertilizer production equipment, the working gap should be re measured and adjusted several times each time to meet the standards before continuing to use.

6. If the organic fertilizer equipment of the programmable controller cannot work, check the power voltage, power plug and socket, connection plug and socket, etc., and check for internal faults in the controller.

Continuously discovering, preventing, and repairing natural degradation, enabling organic fertilizer production equipment to be repaired in potential failure states: The significance of self maintenance, through the participation of frontline employees, identifies problems in the first place and compresses them. Fully standardized production and maintenance of TNPM, advocating for the discovery and elimination of six activity sources, one of the most important links is to solve the problem of fault sources.

Equipment and process flow for producing organic fertilizers from pig manure

Fermentation:

Small pig farms use active (forced) ventilation for composting. The biggest feature of this composting method is that the ventilation pipes with holes are placed in the lower part of the pile body, and then the air is actively transported into the pile body by the fan. This method also does not require flipping, but the oxygen concentration in the pile is better than that of static composting, so the composting speed is relatively faster.

Granulation:

1. Send the qualified organic raw materials into the speed regulating silo with the loader;

2. Transfer to the vertical pulverizer and pulverize to 10-60H;

3. Transfer to the rotary vibrating screening machine to separate raw materials and impurities; also can add mixing equipment.

4. Conveying organic fertilizer granulator machine for granulation, packaging, sewing and storage.

Pig manure organic fertilizer equipment: dehydrator, fermentation turner, semi-wet material grinder, horizontal mixer, npk fertilizer granulator, dryer, cooler, trommel screen, coating machine, packaging equipment, belt conveyor Wait. The organic fertilizer granulator adopts high-speed rotation, and the material is turned over at a high speed with the barrel, so that the powder adheres under the high-speed movement, and continuously realizes the processes of mixing, granulation, spheroidization, and densification in the interior, so as to achieve the purpose of granulation.

Pig manure organic fertilizer equipment is a new type of organic fertilizer that integrates organic fertilizer, chemical fertilizer, amino acid fertilizer and functional microorganisms. Its function is to meet the nutrient needs of crops in the current season, significantly inhibit soil acidification, effectively control soil microbial flora, and improve soil fertility. In terms of equipment, if you are new to this industry, it is recommended to start with a small scale, that is, a small powdered organic fertilizer plant. The required equipment includes a fermentation turner, a feeding bin, a semi-wet material pulverizer, and a disc granulator machine, trommel screening machine, automatic packaging machine, etc. The price of the whole set of equipment is about 150,000.

The workflow and equipment composition of urban sludge dryer

fertilizer granulator Oct 10, 2023

Main characteristics of urban sludge dryer

1. High thermal capacity coefficient and high thermal efficiency. By combining the crushing and stirring device with the rotary cylinder, the total heat transfer coefficient of the sludge dryer is increased to 2-3 times that of a regular rotary dryer. The crushing and stirring device crushes the material, increasing the contact area between the material and the hot air, while also preventing the short circuit of the hot air, making full use of the heat of the hot air.

2. The product particle size is uniform. Due to the addition of flocculants during the dehydration process of sludge from urban sewage plants, the viscosity of the sludge increases, making it prone to agglomeration during the drying process, which not only affects the drying effect but also increases the difficulty of utilization. In a sludge dryer, the mixing and crushing device and the kiln type movable plate inside the cylinder act to break the mud before it hardens, and the final output is uniformly sized particles (about 2mm), making the subsequent treatment or utilization process of sludge more convenient.

3. Easy to operate and operate. The sludge dryer is equipped with an automatic control system, and the biogas burner has a large and small burner combustion mode. The end of the drying drum is equipped with a temperature sensor, which controls the size conversion of the burner head through the temperature sensor, thereby controlling the humidity inside the drying drum and preventing excessive temperature from causing sludge coking. The speed of the rotary drum can be adjusted through the control cabinet.

4. Environmental protection and energy conservation. The sludge dryer uses biogas generated during sludge digestion treatment as heating energy, greatly reducing the cost of sludge drying and creating a new application field for the comprehensive utilization of biogas.

5. Unique arch breaking and vibration device. Effectively solved the problems of material bonding with the body and lifting device, as well as material agglomeration and movement obstruction during the drying process.

Process characteristics and advantages of organic fertilizer granulator

fertilizer granulator Oct 10, 2023

Organic fertilizer granulation equipment is one of the most core equipment in organic fertilizer equipment, which directly affects the quality of organic fertilizer particles (such as roundness, uniformity, fertilizer moisture retention performance, etc.). So, what are the differences in the several processes of organic fertilizer granulation? What are the impacts on product quality? Different granulation processes for organic fertilizers require different types of granulators, which directly affect the yield, quality, appearance, price, and other aspects of the product. It can be said that the organic fertilizer granulator is the core of the entire production line.

The organic fertilizer granulation equipment utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, extrude, collide, compact, and polish fine powder materials in the machine, thus achieving the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3 and 3 millimeters, and a particle formation rate of ≥ 90%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle. Application scope: This machine is particularly suitable for granulation of lightweight fine powder materials, especially for granulation of organic inorganic compound fertilizers. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. It is generally required that the particle size of the material before granulation should be less than 50 mesh. Typical application materials include chicken manure, pig manure, cow manure, carbon black, clay, kaolin, nitrogen, phosphorus, potassium, and other organic inorganic compound fertilizers.

The organic fertilizer special granulation machine is mainly used for granulating various organic materials after fermentation, breaking through the conventional granulation process. The material does not need to be dried before granulation, and after crushing, it can be directly mixed to produce spherical particles, saving energy and high granulation rate. With an organic matter content of over 97, pure organic matter granulation can be achieved without the need for adding binders during granulation. The particles are sturdy and beautiful, and can be sieved and rounded after granulation, reducing drying energy consumption. The moisture content of the raw materials can be between 20 and 50.

Organic fertilizer special granulator is a molding machine that can manufacture materials into specific shapes. The wet stirring tooth granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method has a high ball forming rate, beautiful particles, and also saves energy, which is efficient and energy-saving.
