Equipment process of drum screening machine in NPK fertilizer production line

In the manufacturing of NPK fertilizer, in addition to the drum granulator as the core of the production process, we also need drum screening machine, dryer, mixer, batching system and other equipment. What basic information should we know when using drum screen?

1. Screen material: the part of the material that fails to pass through the sieve hole after screening, which is usually a large piece of unqualified material.

2. Sieve residue: the part of the material passing through the sieve hole after screening, which is the qualified NPK fertilizer granules.

3. Screening efficiency: After the material is sieved, the percentage of the material under the sieve.

4. Screening accuracy: After the material is sieved, the percentage of the amount that meets the sieving particle size specification in the under-sieve will account for the total under-sieve.

5. Hole blocking rate: the percentage of the number of screen holes that are blocked to the total number of screen holes.

The larger the proportion of qualified fertilizer particles screened out by drum screen is, the better granulation effect and higher production efficiency of rotary drum granulator are. We provide different specifications of drum granulation equipment, suitable for a variety of materials granulation processing.

The important role of organic fertilizer production line in processing fertilizers for crops

 1. In the actual agricultural production, the utilization rate of chemical fertilizer is only 30% – 45%. Some of the lost chemical fertilizers are released into the atmosphere, some of them are lost with the water and soil flow, and some of them are fixed in the soil and can not be directly absorbed and used by plants. Moreover, it will cause adverse consequences such as soil salinization and hardening. When we apply organic fertilizer, its beneficial biological activities can improve the soil structure, increase the soil’s ability to retain water and fertilizer, thereby reducing the loss of nutrients. Coupled with the effect of organic matter beneficial microorganisms to dissolve phosphorus and potassium, the effective utilization rate of fertilizer can be increased to more than 50%. The application of organic fertilizer manufacturing process is becoming more and more extensive.


2. Organic fertilizer can increase crop yield and improve the quality of agricultural products. Under the condition of the same nutrient elements, the effect of organic fertilizer is better than that of chemical fertilizer when it is used as base fertilizer. When applied as topdressing, the effect of fully decomposed organic fertilizer is often better than that of chemical fertilizer, especially in improving the quality of agricultural products. Therefore, in the organic fertilizer manufacturing process, adding organic fertilizer into raw materials is more effective.

3. Organic fertilizer can promote the growth of soil microorganism and strengthen the absorption and utilization of crops. Organic fertilizer contains a lot of organic matter, which is a place for the growth and reproduction of various microorganisms. The organic matter of organic fertilizer can also produce various phenols, vitamins, enzymes, auxin and hormone like substances in the process of decomposition, which can promote the growth of crop roots and the absorption of nutrients.

4. Reduce nutrient fixation and improve nutrient availability. Organic fertilizer contains a lot of organic acids, humic acids and other hydroxyl substances, which have strong chelating capacity, can chelate with many metal elements to form chelates, which can prevent the soil from fixing these nutrients and failure. For example, organic acids and other chelates in organic fertilizer can chelate aluminum ions with high activity in soil, prevent the combination of aluminum and phosphorus to form closed storage phosphorus which is difficult to be absorbed by crops, and greatly improve the content of available phosphorus in soil.

Equipment process and working principle of organic fertilizer turning machine

The organic fertilizer turning machine is mainly composed of a frame, transmission device, turning device, and walking device. Its working principle is as follows:

frame:

As the supporting structure of the organic fertilizer turning machine, it carries all the components and materials.

transmission:

Including motors, gearboxes, and sprockets, responsible for providing power and transmitting torque.

The motor reduces the high-speed rotating power to an appropriate speed through the gearbox, driving the sprocket to rotate.

Stacking device:

It consists of a series of interlocking sprockets and a tipping shovel hanging on the sprockets.

The sprocket rotates under the drive of the transmission device, driving the flipping shovel to move up and down, achieving the flipping function.

Walking device:

Including wheels and a walking mechanism, the organic fertilizer turning machine can move within the working area.

According to the design of the stacker, the walking device can be tire type or track type to adapt to different working environments.

working principle:

After the organic fertilizer turning machine is started, the motor drives the gearbox and sprocket to rotate, and the sprocket drives the turning shovel to move up and down.

The tipping shovel picks up organic materials from the bottom of the pile during its ascent and throws them onto the other side of the pile during its descent.

This process is constantly repeated to achieve the flipping and mixing of organic materials, promote microbial decomposition activities, and accelerate the maturation process of organic fertilizers.

Control system:

Modern organic fertilizer turning machines are usually equipped with advanced control systems that can set parameters such as turning frequency, speed, and depth according to process requirements.

The control system can be manual or automatic, and an automatic control system can improve work efficiency and flipping quality.

Through this working principle, the organic fertilizer turning machine can efficiently turn over organic materials, improve fermentation conditions, and enhance the quality of organic fertilizers.

Why do organic fertilizer production lines use fertilizer dryers to process granular fertilizers?

 The granular organic fertilizer manufacturing process includes fermentation, crushing, mixing, granulation, drying and other processes. The production process of NPK fertilizer is similar. So after the granulation of the granular fertilizer production line, why should it be dried?
1. Fertilizer dryers increase the strength of the particles

There is no strict regulation on the strength of fertilizer granules. However, in the process of fertilizer commercialization, the particles with low strength are unfavorable to the transportation of commercialized packaging boxes. In the process of transportation, the low strength will increase the damage rate of particles. Therefore, in order to meet the needs of commercialization, in the manufacturing of NPK fertilizer, granular fertilizer also needs to be dried after molding.


2. Fertilizer dryer can extend the storage period of pellets

As a commercial granular fertilizer, it takes time to store the fertilizer from packaging to application of crops. This requires the preservation of the fertilizer as long as possible without reducing the nutrients of the fertilizer. The loss of nutrients is often due to volatilization and reduced particle strength. After the fertilizer is dried, the storage and transportation period of the particles can be effectively extended.3. Fertilizer dryer can reduce the moisture of particles

The water content of the fertilizer raw materials is relatively high. Although the water content of the material has been reduced during the preliminary fermentation, smashing and mixing, and transportation, it is only reduced to the water content required for processing particles. According to the water content of the standard fertilizer ( Free water) should be ≤30%. The particles processed by the NPK fertilizer granulator have a moisture content between 20% and 40% according to the characteristics of the material. In order to meet the standard, drying and drying are indispensable.

Through the above three points, we can see the importance of fertilizer dryer. After granulation of common NPK fertilizer manufacturing process, drying process is realized by using dryer and cooler.

Key points for process and equipment procurement of organic fertilizer production line

Now many people have a certain understanding of the organic fertilizer manufacturing process and equipment. For environmental reasons, the primary problem faced by breeding sites is how to deal with livestock manure. At this time, the organic fertilizer production line comes in handy.

Many people know that the production line of organic fertilizer is used to treat livestock manure into organic fertilizer. As an organic fertilizer equipment manufacturer, we also teach others how to make organic fertilizer. Now many countries and regions are also vigorously supporting the use of organic fertilizer, so many people want to buy a set of organic fertilizer production equipment to make fertilizer and make profits.


Organic fertilizer manufacturing process mainly includes equipment process

Composting machine — material grinder — blender — NPK fertilizer granulator — rotary dryer — rotary cooler — drum screening machine — coating machine — packaging machine.

Fermentation compost turning machine adopts advanced track, which can be lifted or not. The lifting type is mainly used in the working condition that the width of the tank is not more than 5 meters and the depth of the dump is not more than 1.3 meters. Pig manure composting fermentation dumper has a good limit switch, in the case of any abnormal situation, it can guarantee our safety in time, and also play a role in limiting the amount of materials.

Although the purchase of organic fertilizer production line mainly depends on the price, but the appearance is also very important. The appearance design should be able to meet consumers’ aesthetic point of view, so it can be comfortable to use. Now many manufacturers can customize colors, most of which can be customized according to users’ requirements. In addition, we should pay attention to the details of the equipment, whether the workmanship is fine, whether the welding trace is obvious, whether the screws are in place, and whether the appearance of the whole machine is smooth.

Method of fermenting organic fertilizer in sheep manure organic fertilizer production line

Technology of sheep manure fermenting organic fertilizer

The key processing step of organic fertilizer production line is fermentation process. Due to the different temperature in different places, the temperature in some areas is not high even throughout the year, which has a great impact on the fermentation time of organic fertilizer. The normal fermentation time is about 10 days. With the influence of different temperature in different areas, the whole fermentation cycle can be from 7 to 20 days.

The common method of sheep dung fermentation is trough fermentation, of course there are other methods. Trough fermentation is to use civil engineering to build a cement tank with a width of 3 meters and a length of 50 meters, and then install tracks on both sides of the wall, and the trough-type turning and throwing machine walks on the track to turn and throw the materials regularly. Put the sheep dung raw materials into the tank, generally the stack height is about 70 cm.

Then adjust the moisture of the raw materials. When the moisture is too high, add straw powder, rice husk and other organic plant residues. When the moisture is too small, pour into water or livestock and poultry urine. Adjust the moisture to 60%. Add organic fertilizer and start fermentation. Generally, 1kg of starter can ferment about 10t of raw materials.

In the fermentation process, trough compost turning machine is used to turn the pile once every two days, or turn and discard according to the temperature of the raw materials. Until the fermentation is complete.

Other processing processes of sheep manure after fermentation

In fact, after the sheep manure fermentation is completed, it will be regarded as organic fertilizer, but if we want to reach the standard of commercial organic fertilizer, we have to carry out the next step of processing. For organic fertilizer, the content of N, P and K should be 5% respectively, while the content of NPK in fermented organic fertilizer is not up to the standard of organic fertilizer, although it is rich in nutrients. It is necessary to use compost for granulation and add inorganic fertilizer in the process of granulation. Similarly, adding decomposed sheep manure compost in NPK fertilizer manufacturing process can greatly improve the fertilizer efficiency of finished products.

How to choose organic fertilizer granulators for pig manure fertilizers in different regions

When granulating pig manure fertilizers in organic fertilizer granulators in different regions, factors such as local climate conditions, soil types, crop planting characteristics, and environmental regulations should be considered. Here are some suggestions:

Climate conditions:

In areas with humid climate, dry granulation or semi dry granulation should be prioritized to reduce nutrient loss caused by high humidity and avoid compaction of soil by excessively wet fertilizers.

In arid areas, wet granulation of organic fertilizer granulators can help maintain the moisture content of fertilizers and prolong the release time of fertilizer efficiency. However, attention should be paid to controlling the moisture content reasonably to avoid affecting the storage and transportation of fertilizers due to excessive moisture.

Soil type:

For poorly drained clay soils, dry granulation methods that can provide faster fertilizer release should be selected to avoid soil salinization caused by excessive nutrient accumulation.

For well drained sandy soil, wet granulation can be used to fully utilize the nutrients in pig manure fertilizers while reducing nutrient loss.

Crop planting characteristics:

For vegetables and crops that require rapid growth, dry granulation should be chosen to meet their rapid nutrient absorption needs.

For long-term crops and fruit trees, wet granulation is more suitable because it can provide a long-lasting and stable supply of nutrients, which helps with the long-term growth of crops.

Environmental regulations:

In areas with strict restrictions on pollutant emissions, priority should be given to using environmentally friendly organic fertilizer granulation processes, such as combining biological fermentation technology with dry granulation, to reduce the generation of wastewater and waste gas.

For areas with specific environmental requirements, granulation processes that comply with local environmental standards should be adopted, and corresponding pollution control measures should be taken.

Resource recycling and utilization:

Encourage the use of pig manure resource utilization technology, such as anaerobic fermentation to produce biogas that can be used for energy recovery, reducing dependence on fossil fuels.

After appropriate pretreatment, pig manure can be used to produce organic fertilizers and achieve resource recycling.

Technical training and guidance:

Provide necessary technical support and training to help farmers master advanced pig manure fertilizer granulation technology and ensure its correct application in agricultural production.

Promote scientific fertilization methods, such as formula fertilization and precision fertilization, to improve the efficiency of pig manure fertilizer use and crop yield.

Through the above measures, it can be ensured that the granulation treatment of pig manure fertilizer is applied reasonably in different regions, which can effectively improve the utilization rate of pig manure fertilizer and protect the local environment.
