Organic fertilizer granulator machine occupy an important position in the entire organic fertilizer production line. Organic fertilizer granulators are divided into drum granulators, flat die granulators, extrusion granulators, disc granulators, etc. Although the working principles are different, the daily maintenance methods are basically the same. We do a good job of organic fertilizer The purpose of the daily maintenance of the granulator is to reduce and avoid equipment damage and economic losses caused by organic fertilizer production operations. So how to maintain the organic fertilizer granulator in daily use?

Maintenance method of organic fertilizer granulator machine:
1. Keep the work site clean. After each test of the organic fertilizer equipment, the residual rubber sand inside and outside of the granulating leaves and the granulation pot should be completely removed. The rubber sand and the flying objects scattered or splashed on the organic fertilizer equipment should be cleaned. The exposed working surface of the machine is wiped clean, coated with anti-rust meat paint, and covered with a corresponding cover to prevent secondary intrusion of dust.

2. Organic fertilizer equipment has no external refueling holes. Gears and worm gears are lubricated with special grease for organic fertilizer equipment. The upper gear and the lower gear should be filled with butter three times every season, and the moving gear box cover and the transmission gear cover can be opened separately when refueling). Oil should be lubricated from the sliding surface between the supporting gear box and the sliding surface of the bracket. Worm gearboxes and bearings have been filled with transmission butter when they leave the factory, but the gearbox machine should be thoroughly cleaned after every one year of use and all protective lubricants replaced.

3. Always pay attention to the operation of organic fertilizer equipment. There should be no serious abnormal noises and no metal friction sounds. If any abnormality is found, stop using it immediately and inspect it. Use it only after troubleshooting. The reason cannot start the machine. If there is metal friction, check the gap between organic fertilizer equipment first.

4. often check the standard gap between organic fertilizer equipment.

5. When the organic fertilizer equipment is overhauled, the working gap should be re-determined each time, and adjustments should be made multiple times. It can only be used after meeting the standards.

6. If the organic fertilizer equipment cannot be operated by pressing the programmer, check the power supply voltage, whether the power plug socket, connection plug socket, etc. are normal, and check the internal faults of the controller.

Green development has now become an important goal. The pollution in our country is very serious, especially in terms of ecology. In the case of numerous livestock farms, the pollution caused by livestock manure is very serious. It not only pollutes the environment and land seriously, but also pollutes groundwater. Therefore, the treatment of livestock manure pollution is very important, And organic fertilizer equipment is specialized in handling livestock and poultry manure, which can effectively solve the pollution of livestock and poultry manure and make it into organic fertilizer. Therefore, organic fertilizer equipment is now recognized by many people.

From the environmental protection situation in the past two years, the country has made great efforts to address environmental pollution, especially soil pollution. Currently, the country is vigorously promoting the use of organic fertilizers, which are generally produced using organic fertilizer production lines. Why use organic fertilizers? Due to the serious soil compaction situation, if left untreated, it will seriously affect the yield of grain, and the use of organic fertilizers is necessary to control soil compaction and make the soil fertile.

It is understood that the production of organic fertilizer mainly involves the organic transformation of livestock waste, food and drug residues, and industrial sludge, ultimately returning them to the field, ensuring that the environmental protection loop does not produce pollution. Expert introduction, Crop straw and other plant residues, livestock and poultry manure, agricultural by-products, household waste, as well as biogas residue, peat, plant ash, sludge, and urban sludge, can all be used as raw materials for organic fertilizers. The use of organic fertilizers can help upstream production enterprises dispose of waste and reduce pollution to the agricultural and animal husbandry industry. On the other hand, compared to fertilizers, organic fertilizers play a crucial role in the development of ecological agriculture

The production process of the double roller granulator is simple, with low energy consumption and large output. Direct granulation of dry powder does not require subsequent drying processes, which is more conducive to the connection and transformation of existing production processes. The particle strength is high, and the increase in bulk density is more significant than other granulation methods. Especially suitable for occasions where the stacking weight of products is increased. The operation flexibility is large, the adaptability range is wide, and the extrusion pressure can be adjusted through hydraulic pressure.

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 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.

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.

Organic fertilizer granulator machine is an indispensable machine in organic fertilizer production line. In normal use, only by doing maintenance work can it ensure a longer service life. What questions need to pay attention to in daily use? The following content tells you the answer.

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.

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.

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.

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.

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.
