Category: Fertilizer granulator machine

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 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.

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.

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.

 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.

Organic fertilizer equipment is also known as organic fertilizer production lines. Building a complete set of organic fertilizer equipment can effectively carry out organic fertilizer production and improve the output and quality of organic fertilizer. Many businesses do not know how to establish organic fertilizer production lines, and do not know what conditions are required to build organic fertilizer production lines. Today, let me take you through.

According to the process stages, the granular organic fertilizer production line process is divided into 1 crushing process; 2. Fermentation process; 3. Mixing process; 4. Granulation process; 5 Drying process; 6. Screening process; 7. Coating process; 8 Packaging process.

The complete organic fertilizer production line equipment portfolio includes: fermentation tipping machine, semi wet material crusher, horizontal mixing mixer, new organic fertilizer granulator, rounding machine, rotary dryer, rotary cooler, drum screening machine, and automatic packaging machine.

So what are the conditions for building a small organic fertilizer production line?

1. The construction of small organic fertilizer production lines should comply with environmental protection policy requirements. For environmental protection, it is not only the desire of the public, but also the policy demand for environmental protection in the development of agriculture and animal husbandry;

2. Source of raw materials, surrounding the source of raw materials, determining your factory location, site investment, transportation investment, etc;

3. The type of raw materials determines the detailed equipment used in each process stage, which affects the equipment investment price, etc;

4. Production scale: The annual output of small organic fertilizer equipment ranges from 3000 tons to 20000 tons, which determines the capacity requirements of the equipment, thereby affecting prices, etc;

5. The recycling of resources mainly relies on various ways of recycling agricultural surface pollution wastes, such as first making fuel and electric energy raw materials, and the generated biogas residue as organic fertilizer raw materials;

Other uses of this small organic fertilizer production line process can be used as feed, etc;

7. Plant construction site: It is necessary to determine the production site size and site size investment based on the planned production scale.

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.

Organic fertilizers include powders and granules. In the organic fertilizer sales market, the price of granular organic fertilizers is higher than that of powdered organic fertilizers. This is because, after the fertilizer is made into granules, the weight is appropriate and it is not easy to be blown away by the wind. Granular organic fertilizers are not as susceptible to moisture and caking as powdered fertilizers, making them easier to apply. Some inorganic components can also be added during the granulation process to improve fertilizer efficiency. Organic fertilizer granulation requires professional organic fertilizer granulation equipment. Next, let’s take a look at commonly used granulation equipment.

1. Double roll extrusion granulator

The counter roller extrusion granulator is a key equipment for granulating compound fertilizer. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and forms a miniaturized assembly line with related equipment, which can form a certain production capacity of continuous and mechanized. Using the eugenic formula, it does not require drying, is produced at room temperature, and is rolled in one step to ensure that the product quality meets the requirements of the technical indicators for compound fertilizers. It is an updated product dedicated to high, medium, and low concentration compound fertilizers for various crops and energy conservation and consumption reduction in the compound fertilizer industry. The shape and size of the roller skin ball socket of this series of granulators can be selected by users according to their needs, with a wide range of ball pressing shapes including pillow shaped, semicircular, rod shaped, sheet shaped, ball shaped, walnut shaped, flat ball shaped, and strip shaped.

2. Disc granulator

This fertilizer granulation equipment is a relatively common granulation equipment. The disc granulation equipment, also known as a ball disc, adopts an overall circular arc structure, with a granulation rate of over 93%. Mingda disc granulator can improve labor productivity. Flexible belt transmission is used between the reducer and the motor, ensuring smooth starting and slowing down the impact force. It has a protective effect on the disc granulator. Mingda disc granulator is an ideal fertilizer granulation equipment with non deformable and uniform granulation.

3. Drum granulator

Unlike other granulation equipment, this machine is a molding machine that can shape materials into specific shapes. The granulation method is wet pelletizing. After using a certain amount of water or steam to wet the base fertilizer in the drum, the material is squeezed and aggregated into a sphere through the rotary movement of the drum. The drum granulator is suitable for cold and hot organic fertilizer granulation and high, medium, and low concentration compound fertilizer granulation.

The three types of granulation equipment mentioned above are commonly used in fertilizer granulation, with respective advantages. Different types of granulation equipment can also be customized according to different needs, so the prices vary.
