How to maintain unexpected wear and tear of organic fertilizer equipment

fertilizer granulator Apr 6, 2023

Organic fertilizer equipment inevitably experiences wear and tear during operation. Within the safe service life of the equipment, these controllable damages and wear may not have a significant impact on the equipment, so there is no need to worry too much. However, severe wear and tear is different. Some only affect the normal operation of the equipment, while others can also cause safety hazards. Therefore, manufacturers should carry out inspection and management of the wear and tear of organic fertilizer equipment.

Eight unexpected wear and tear situations of organic fertilizer equipment:

1. Break-in wear: This is the most common normal wear and tear of organic fertilizer equipment. When friction begins between new friction surfaces, the wear rate is faster. After reaching a certain level, the actual contact area between the friction surfaces increases, and the unit pressure decreases accordingly, resulting in a decrease in wear rate.

2. Grinding wear: Wear caused by hard particles cutting off the worn surface.

3. Adhesive welding wear: caused by factors such as too light a certain material on the friction surface, excessive contact pressure, poor lubrication conditions, or high temperature.

4. Fatigue wear: This occurs more frequently on friction surfaces with rolling friction, manifested in the formation of crack surfaces on the friction surfaces of parts, leading to metal surface detachment. The main reason is that the contact pressure of the surface material exceeds the compressive limit strength due to compression, elastic extension, and cold and hot effects.

5. Corrosion and wear: The friction surface undergoes oxidation and deterioration due to the continuous infiltration of media such as water vapor, chemical gases, or oxides between the friction surfaces. Generally, it is oxidation wear and chemical corrosion wear.

6. A relatively easy factor to cause wear and tear on organic fertilizer equipment is dust. Organic fertilizer equipment actually generates a certain amount of dust during operation and after discharge. If not cleaned and maintained in a timely manner, the dust will enter various connections within the equipment, accumulating over time. As the amount increases, the friction at the equipment connections will increase, and even bacteria will accumulate, causing corrosion to the equipment and affecting its performance. So we require the staff to conduct a comprehensive inspection and maintenance of the organic fertilizer equipment in addition to using it.

7. During the operation of organic fertilizers, our staff also need to pay attention to the lubrication of the equipment connections. Long term use of the equipment poses a severe challenge to equipment lubrication. Once there is a lag, the friction force of the equipment will increase. Only high lubrication will provide good power support for the operation of organic fertilizer equipment, and staff should develop a good habit of regularly cleaning and maintaining the equipment.

8. In addition, we need to pay special attention to motor friction, otherwise it will affect the effectiveness of organic fertilizer equipment. The staff should pay attention to constantly checking the operation of the motor. Especially before running under load, the circuit of the motor should be checked and updated immediately if there is any damage to ensure safe operation.

The above 8 accidental damages and their causes can actually be avoided through normal maintenance in daily life. There are 5 daily maintenance elements to be done.

1. Machines and parts that have a significant impact on the system and have no maintenance time.

2. Patrol and inspect the oil supply, abnormal noise, vibration, temperature, etc. of the machine and parts; If these machines and parts are not inspected and processed daily, they may cause major accidents.

3. Although the impact on the system is relatively small, machines and parts that are prone to abnormal conditions.

4. Conduct corresponding inspections at the start and end of the day.

5. Regular inspection, adjustment, and cleaning of organic fertilizer equipment should be carried out.

Equipment characteristics of disc granulator in NPK fertilizer production line

fertilizer granulator Apr 6, 2023

The disc granulator has the characteristics of stable operation, sturdiness and durability. It is a common granulation equipment in organic fertilizer production line. The principle is that after the powdery material is added to the rotating disc, a water spray device is added to continuously spray water, and the material is made into granules under the effect of rolling friction of the material. Different materials have different granulation effects, such as ball formation rate, particle size, granulation amount, etc.

The discs granulated by the fertilizer granulator machine adopt the overall arc structure, and the granulation rate can reach more than 93%. The granulating disc is provided with three discharge openings, which is convenient for intermittent production operations, greatly reducing labor intensity and improving labor efficiency.

The reducer and electric motor are driven by flexible belts, which ensures smooth starting, reduces impact and cushions, and improves equipment life. The bottom of the granulating disk is strengthened with multiple radiant steel plates, which is durable and never deformed. Thicker, heavier, and sturdy base design, no anchor bolts required, smooth operation.

The disc granulator is widely used for conveying various non-stick materials such as pulverized coal, cement, clinker, fertilizer, etc. in powder, material or small blocks.

The inclination of the large plate can be adjusted. The angle gasket is adopted for flexible and convenient adjustment, and the unique unpowered combination scraper blade is integrated to reduce the auxiliary power consumption. The large disk is composed of a disk body and a disk section, which reduces the power of the main motor. The disk section can be adjusted up and down along the disk body. The end of the disk section is a side flange. When the ball is out of the disk, it can ensure that the ball is not pulled or torn.

The influence factors on the wear of the roller shell of the double roller granulator

fertilizer granulator Mar 31, 2023

The role of double roller granulator in organic fertilizer processing, such as mixed fertilizer. Regular hemispherical groove of roller skin is formed by squeezing each other. This extrusion pressure is inevitable in the wear of the double rollers of the double roller granulator. How to reduce the wear of roller sleeve should start with several reasons, and consider the corresponding countermeasures according to the wear reasons.

The influence factors on the wear of the roller shell of the double roller granulator

1. material factors
Roller extruder mainly processes dry powder materials. Because of the different hardness of the material, uneven force will be produced during extrusion and ball forming, which will increase the wear of the roller skin. From the material factor, another factor is the uniformity of the particle size of raw materials. Different sizes of raw materials can also lead to uneven force and wear of roller cover.

2. material factors of roller skin of double roller granulator
The roller surface of the roller fertilizer granulation machine is friction material and direct force. In the process of roller wear, friction and back extrusion pressure of materials can not be ignored. This force requires higher quality of roller skin, slower wear speed with good quality and faster wear speed with poor quality.

3. uniformity coefficient of feed
The center of parallel rod axis of the counter roller granulator is parallel to the surface of the roll skin. If the feeding is seriously uneven, one end of the feeding is more, and the other end is less, it will cause uneven force on both ends of the roller, increase the friction between the roller and the material, and cause the roller wear.

4. raw material moisture and pH
The roll skin is made of stainless steel. The organic fertilizer granulation machine has strong reaction to the acid and alkali of the material. The moisture and pH of the material are not good, which leads to acid-base corrosion on the surface of the roll skin and damages the roll skin.

5. work operation injury
If the operation is not in accordance with the operation procedures, the gap between rollers is not adjusted in place, or the feeding of the roller granulator is unreasonable; the other is that the material is not clean and contains impurities such as iron and sulfur. The color of the roller skin is seriously damaged.

Fertilizer granulator for wet granulation of organic fertilizer

fertilizer granulator Mar 31, 2023

Huaqiang heavy industry produces wet fertilizer granulation machine: disc granulator, drum granulator, organic fertilizer wet granulator and new two in one granulator. The main difference between these kinds of fertilizer granulators lies in the different raw materials and methods.

The moisture in wet granulation is the key factor to form the liquid bridge between the original particles. The pre wetting of powder before agglomeration is helpful to the formation of micronuclei and the quality of granulation. However, the amount of water added in different powder materials and granulation methods is also different, which is generally determined by experiments.

The new two in one organic fertilizer granulator is specially used for the granulation of organic fertilizer. The new two in one organic fertilizer granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization and densification of fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥ 90%. The size of the particle diameter can be properly adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotational speed, the smaller the particles, and vice versa.

Application scope: This organic fertilizer granulation machine is especially suitable for granulation of light and fine powder materials. The finer the basic particles of fine powder materials are, the higher the sphericity of particles is, and the better the quality of pellets is. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

1. Always check the working status of each component on the organic fertilizer granulator.

2. Always check if there are loose parts on the organic fertilizer granulator.

3. Always check the bearing oil temperature of the granulator to ensure that it is within the normal range.

4. Check the components of the organic fertilizer granulator from time to time to make sure that they are not worn.

Organic fertilizer granulator machine daily maintenance:

1. First, remove the dirt and debris outside the organic fertilizer granulator machine, clean and lubricate all bearings, and cover the friction surface with anti-corrosive agents such as paint, black oil and waste engine oil;

2. The organic fertilizer granulator placed in the open air should flatten or erect those parts that are prone to deformation to eliminate the factors that cause deformation. If the spring is supported, the spring should be relaxed;

3. When not working, we should remove the parts that are easily rusted or damaged in the organic fertilizer granulator, especially the motor, reducer, conveyor belt, transmission chain, etc., should be removed and stored indoors, and separated by machine category to prevent deformed or damaged by squeezing each other.

New type fertilizer stirring tooth granulator for processing organic fermentation products

fertilizer granulator Mar 31, 2023

With the diversification of raw materials, organic fertilizer manufacturers are constantly developing new granulation equipment. In the production of ordinary organic fertilizer, there is a stirring tooth fertilizer granulator, which has high production efficiency and good product quality. In terms of organic-inorganic compound fertilizer, there is also a new NPK fertilizer granulator, which is improved on the basis of the agitating gear granulator, which solves the problem of material adhering to the wall and produces beautiful particles.

Performance of new type NPK fertilizer granulator

(1) With the development of agriculture, the improvement of technology and the diversification of demand, the new NPK fertilizer granulator is a kind of organic fertilizer granulator. The wet granulator of organic fertilizer can realize the material selection. As long as the organic matter after effective fermentation can be granulated by the new granulator, which breaks the limitations and obstacles of the traditional process.

(2) The compressive strength of NPK fertilizer granulator is higher than that of disc granulator and rotary drum granulator. There is no need to stop the processing of raw materials, crushing and drilling before granulation, so it can directly realize batching processing and direct granulation. The granulation equipment is suitable for many kinds of organic fermentation products, such as livestock manure, grain straw, mushroom residue, sawdust, soy sauce residue and so on.

(3) This kind of drum granulator not only saves a small amount of electric power investment, but also improves the production efficiency of organic fertilizer, which is convenient and quick with satisfactory effect.

The diversification of raw materials promotes the diversification of organic fertilizer granulation equipment. Only by choosing the organic fertilizer making machine suitable for its own materials can the whole set of organic fertilizer equipment give full play to its efficiency.

Why use organic fertilizer manufacturing machines to grow plants

fertilizer granulator Mar 31, 2023

The nutrient content of chemical fertilizer is high and the fertilizer efficiency is fast, but the effective period is short and the nutrient is single. Organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can complement each other to meet the nutrient requirements of crops in different growth stages. Organic fertilizer manufacturing machine is indispensable for the growth of plants.

If only acid fertilizer is applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid roots combine with hydrogen ions in soil to produce acid, which will lead to acid strengthening and soil hardening. If mixed with organic fertilizer, it can enhance the buffer capacity of soil, effectively adjust the pH value and prevent the increase of soil acidity. In addition, the different nutrients needed by plants are made into granules by a roller granulator, and scientifically matched, the fertilizer efficiency is better.

Organic fertilizer improves soil. The beneficial microorganisms in the microbial fertilizer can produce carbohydrates, which account for 0.1% of the soil organic matter. Combined with plant mucilage, mineral embryos and organic colloids, they can improve the soil aggregate structure, enhance the physical properties of the soil and reduce the loss of soil particles. Under suitable conditions, it can also participate in the formation of humus. Therefore, the application of the microbial fertilizer produced by the organic fertilizer production equipment can improve the physical properties of the soil and help improve the soil fertility.

Precautions in the production process of biological organic fertilizer production line

fertilizer granulator Mar 31, 2023

The key to the production process of biofertilizer project is the choice of granulation method. According to the production process requirements, the currently used granulation methods of bio-organic fertilizer are mainly disc granulation and tooth-granulation. Due to different requirements of raw materials for different granulation methods, there are differences in the production process of biological organic fertilizer. At present, the production technology of Huaqiang organic fertilizer equipment mainly includes the following.

Using the disk granulation production process, the raw materials need to be dried to remove a certain amount of water (when drying, the raw materials are sterilized), and then crushed, and then a certain amount of acid and alkali is added to adjust the pH of the carrier and mixed with the inorganic fertilizer part, and sent The disc fertilizer granulator machine sprays a certain amount of bacteria during the granulation process, and the granulated product is dried and sieved at low temperature to obtain the finished product.

The tooth-granulation granulation process is to use the high-speed rotating mechanical stirring force and the aerodynamic force generated thereby to continuously realize the process of mixing, granulating, spheroidizing and densifying the fine powder in the machine, thereby achieving the purpose of granulation. The shape of the particles is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. The size of the particle diameter can be appropriately adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the rotation speed The higher, the smaller the particles, and vice versa.

The most important thing for the construction of organic fertilizer equipment is to adapt measures to local conditions. A good organic fertilizer production line is not only a guarantee of output, but also a guarantee of quality. Although the organic fertilizer equipment is only a combined process, the convenience it brings to people is unimaginable. Taking an organic fertilizer processing plant with an annual output of 200000 tons as an example, the equipment for the organic fertilizer production line is essential for starting an organic fertilizer processing plant. A complete set of organic fertilizer production line equipment, from fermentation equipment, crushing equipment, stirring equipment to the final coating machine, costs between 350000 and 550000 yuan. The price difference depends on whether you choose a high configuration equipment or a medium configuration equipment.

Factors affecting the processing of fertilizer by double roller granulator

fertilizer granulator Mar 28, 2023

Due to the significant advantages of its extrusion molding process, counter double roller granulator s have been widely used in fertilizer production and processing. Generally, fertilizer extrusion granulators are more commonly used. Due to the physical characteristics of fertilizer itself, the specific gravity, roundness, and strength of granular fertilizer produced and processed meet good specifications. All of this is due to the roller skin of the extrusion granulator. This article will introduce you to the knowledge of the roller skin.

The double roller granulator is produced and processed using a process without drying at normal temperature. The production and processing capacity of our factory is 1 ton/hour, 1.5 tons/hour, 2 tons/hour, and other models and specifications, which are available for users to choose based on their needs. The machine has low investment, good effect, and good economic returns. It is crucial to ensure simple operation, safe and reliable operation, and convenient maintenance during the production process. Raw materials have a wide range of applicability, and are relatively suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, and ingredients. The equipment has a high granulation rate.

For a pair of double roller granulator, the pair of roller skins that interfere with its granulation effect is the one. Circular pits of the same depth are regularly scattered on the roller skin. When two circular rollers rotate directly opposite each other, the two half pits fit each other to produce a circular abrasive tool with an overall empty core. During the production and processing of fertilizer, raw materials are continuously pressed into this type of circular abrasive by the roller skin, resulting in circular particles. This type of particulate matter not only has a beautiful appearance, but also has good strength, and is not easily crushed due to bumps or stacking.

For particulate matter, it is very important to standardize the production of the circular pits on the surface of the roller skin of the roller extrusion granulator. It not only interferes with the formation of fertilizer, but also interferes with the ability of the finished fertilizer to shell. If it cannot be successfully shelled, the fertilizer will stick to the circular pits and cannot produce the finished circular particulate matter. Compared to the organic fertilizer extrusion granulator, the corrosion of fertilizer on the roller skin can cause interference due to the untimely cleaning of fertilizer on the roller skin.

Another thing about the roller skin is its material. To put it bluntly, the extrusion granulator relies on the force of extrusion to produce fertilizer, so the roller skin will suffer certain wear under the action of external forces. Generally, good roller skins are made of high-grade materials and undergo strict heat treatment processes, which greatly improves the surface hardness of the roller skin of the extrusion granulator and increases its service life.

So how long is the service life of the roller skin of a pair of double roller granulator? Different roller skin processing manufacturers have their own supply channels, with greatly different materials. Moreover, the quality of heat treatment production can also interfere with its hardness, which can also have a certain impact on the life of the roller skin. More importantly, the frequency of use. If the continuous production and processing of fertilizer, the roller skin will consume quickly, so this issue cannot be generalized.

How to improve the granulation efficiency of organic fertilizer granulators?

fertilizer granulator Mar 28, 2023

 Organic fertilizer granulator machine is the latest technology product developed by the Agricultural Machinery Research Institute for many years of compound fertilizer processing equipment design and production experience, and has obtained national utility model patents. It is used to granulate various organic substances after fermentation, which breaks through the conventional organic granulation process. Before granulation, the raw materials can be processed into pellets without drying and pulverizing, and direct pelleting can be used to save a large amount of energy. How to increase the output of organic fertilizer granulator?

First. Control the moisture of granulated materials
1. According to the characteristics of the powder: composition, fineness, viscosity, humidity, temperature, etc., control the moisture content of the granules at about 30-28%.
(1) Too little water content. It is difficult to form balls. The yield is low.
(2) Too much water content. There are many large balls. The ball surface is sticky. It is easy to block the sieve surface.
(3) Appropriate water content, more balls and high yield.

2.How to check the particle water quantity in the organic fertilizer production line: the simplest and most practical way-feel method: the hand grabs a ball of material from the stirred material. The hand can form a ball. Touch it with your finger It can be loosened. There are many grains produced in this way. The output is high and it is not easy to block the sieve surface.

Second.Strictly control the quality of good powder
1. According to the formula of organic fertilizer, carefully control the quality of various raw materials such as chemical fertilizers.
2. When Raw materials are discharged and feeding. Iron blocks are strictly forbidden. Stones larger than 10mm. Wooden blocks larger than 10mm. Rice bran and sand should not have more quality indicators. More serious results in low yield.

Third.The main technical key of operating organic fertilizer granulator
1.The particle size of the fertilizer is 70-90 mesh.
2. Do a good job of employee technical training. Improve the technical quality and operating skills of workers.
