Benefits of organic fertilizer on agricultural production

Organic fertilizer is made from livestock manure, straw and other raw materials through fermentation and decomposition of beneficial microorganisms. The direct use of non rotting organic substances will cause serious problems, such as root burning, chicken pox and other diseases, which will seriously affect the quality and efficiency of fruits. The process of fermentation and decomposition is mainly through the high-temperature aerobic fermentation of microorganisms (the decomposition temperature can reach more than 80 ℃), harmless, stable and deodorized substances to form organic fertilizers, which are conducive to the growth and development of fruit trees and improve the soil.

Organic fertilizer is a kind of organic fertilizer and a certain number of functional microorganisms. After the impurities in livestock manure, crop straw, agricultural and food processing products and organic wastes are treated, it is combined with multifunctional fermentation seed agent, rapid deodorization, maturation and dehydration, and then added with functional biological seed agent for treatment. It meets the chemical fertilizer principle requirements for the production of safe and pollution-free green agricultural products, and is a promising fertilizer. When applying bio organic fertilizer to vegetables, we must master the correct fertilization method to obtain good fertilization effect.

There are two types of machines that you can obtain for producing dry chicken manure pellets. This will include a flat die granulator and a double roller granulating machine. A flat die granulator is a self-contained machine that can be positioned in any indoor facility. The manure is added to the top, and the pellets are produced by compressing the material from up above. A double roller granulator is a machine that can produce pellets by rolling two separate rollers that come together. The pellets will be made, and will be dropped out at the bottom. Once they are dry, you can package them, or you can simply use them on your crops.

The double roller granulator is the key equipment for compound fertilizer granulation. It is advanced in technology, reasonable in design, compact in structure, novel and practical, and low in energy consumption. It forms a small production line with corresponding equipment. It can form a continuous, mechanized production with a certain capacity, without drying, and under normal temperature. The product is rolled and shaped at one time to make the product quality meet the requirements of compound fertilizer technical indicators. It is used to produce high, medium Low concentration special compound fertilizer and the updated products for energy conservation and consumption reduction in the compound fertilizer industry.

Capsule filling particles, pigments, detergents, catalysts, strontium carbonate, chemical fertilizers, white carbon black, inorganic salts, chlorides, cyanuric acids, pesticides, oxides, etc., as well as industrial recovered dust materials: such as iron foundry dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust, etc The material is forced into shape by mechanical pressure, without any wetting agent, and the product purity is guaranteed.

The production process of double roller granulation is short, with low energy consumption and large output The dry powder is directly granulated, without the need for subsequent drying process, which is more conducive to the connection and transformation of the existing production process. The particle strength is high, and the increase of bulk specific gravity is more significant than other granulation methods. It is especially suitable for the occasion of increasing the bulk weight of products. The operation flexibility is large and the adaptability is wide. The extrusion force can be adjusted by hydraulic pressure.

What fertilizer production line and granulator equipment are needed for granular organic fertilizer

In the processing of high quality granular fertilizer, NPK production line directly granulates different fertilizers. In the process of organic fertilizer production, fermentation needs to be carried out first, and the fermentation process takes 45-60 days. In this process, the temperature should be raised first to eliminate pathogenic pathogens and some harmful microorganisms in plants, because these products have certain harm to plants and produce, and the metabolites are also unstable and not easy to be absorbed by plants. In the later cooling period, microorganisms will undergo humus of organic matter, and produce a large number of metabolites beneficial to plant growth and absorption.

The temperature rising stage of organic fertilizer fermentation:

In the initial stage of composting, the microorganisms in compost mainly include medium temperature and good gas. They start the fermentation process of composting, and decompose easily organic matter under the condition of good gas, and generate a lot of heat. The composting temperature is constantly increased, rising from 20 ℃ to 40 ℃ to medium temperature stage. During this period, a compost turning machine is needed to process the compost.

High temperature stage of composting:

In the high temperature stage, thermoactinomycetes and thermogenic fungi become the main species. They strongly decompose the complex organic matter in the compost, accumulate heat, and the compost temperature rises to 60-70°C, even as high as 80°C. Immediately, most of the thermophilic microorganisms also died in large numbers or entered a dormant state.

The cooling stage of compost fermentation:

After a certain period of time, most of cellulose, hemicellulose and pectin have been decomposed, and the complex components and newly formed humus which are difficult to decompose are left. The activity of microorganisms is weakened and the temperature gradually decreases. When the temperature drops below 40 ℃, the mesophilic microorganism becomes a dominant species.

Composting stage:

After the compost decomposes, its volume shrinks and the compost temperature drops to slightly higher than the temperature. At this time, the compost should be compacted to cause an anaerobic state and weaken the mineralization of organic matter to facilitate fertilizer preservation. The decomposed compost can be made into high-quality fertilizer pellets with a fertilizer granulator.

Working principle and characteristics of double roller granulator for dry granulation

Working principle of double roller granulator

When the double roller granulator works, it is forced to roll the material into shape by two opposite moving roller skins of the granulator. Semi circular spherical cavities are regularly distributed on the two cylindrical roller skins. When the roller skin rotates against each other, the two semicircular cavities just form a complete spherical mold, and the materials inside are forced to be extruded into spherical particles. Due to the continuity of extrusion production, the particles and particles are connected together when they are just extruded, forming a cloth full of particles, which needs to be broken up by the crushing roller and divided into small round particles, and then screened from the screen to select the qualified particles.

double roller granulator

In the production of granular fertilizer by double roller fertilizer granulation machine, it should be noted that the ball socket on the two roller skins should be in good position. If it is not adjusted in place, there will be a certain dislocation during granulation, which can not produce qualified granular fertilizer. In addition, after the formation of particles, they will be released from the ball and socket of roller skin in time, so as to realize continuous production. If the formed particles do not come out in time, complete particles will not be formed, thus affecting the normal production.

Characteristics of double roller granulator for dry granulation
1. There is no drying process in the organic fertilizer granulation machine. It is granulated at room temperature and formed in one time. It has the advantages of less investment, quick effect and good economic benefit.
2. Compound fertilizer double roll extrusion granulator has small power, reliable operation, no waste discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology and low production cost.
3. The material of the roller extrusion granulator is widely used, not only in fertilizer industry, but also in all kinds of chemical raw materials such as snow melting agent.

Environmental protection granulation process of double roller granulator

The double roller granulator uses the way of forced extrusion to make particles, the whole process does not need drying and cooling, and the equipment investment is small. What’s more important is that this granulation method is a very environmentally friendly production mode because it is made of particles by physical methods, and the whole process has no pollution and no waste.

Controlling the rotary drum granulator to improve the particle roundness

The time and frequency of material rolling in the rotary drum granulator are the primary factors to determine the pelletizing rate and particle roundness. The roundness of granular product in fertilizer production line can be improved by controlling the drum granulator.

Production principle of rotary drum granulator

Materials rely on surface tension, proper amount of liquid phase, extrusion force generated by rolling between materials, and correct movement direction of materials in the granulator, with small particles as the core, they absorb and adhere to each other and form balls in rolling. In a certain period of time, the higher the rolling frequency is, the higher the spheroidization rate is, and the rounder the particles are.

In the process of production, we have encountered two kinds of situations due to the different friction between materials and the wall of granulator.
1. The internal surface finish of granulator is large, so that the friction force between material and cylinder wall is reduced, and the upward movement force of material is weakened. If the material does not roll, it will not produce particles. In view of this situation, we can solve this problem by adjusting the speed of the granulator and installing a small plate inside.
2. The material in the drum granulator is severely stuck to the wall, and the friction between the material in the granulator and the wall of the barrel is increased, which raises the material in the machine too high, causing the material to fall from the top, so that the formed particles are not Rounding and excessive large particles, we think there are two reasons for this situation: on the one hand, the material is caused by too much viscous material, in this case, we change the formula of the npk production line to reduce the amount of viscous material; on the other hand , The inside of the granulator is not smooth. In this case, we change the internal material to increase the smoothness of the granulator.

On the other hand, we should also control the reasonable amount of material returned to the whole fertilizer production line. The process of rotary drum steam granulation is different from that of general fertilizer granulator, the relative pelletizing rate is lower, and the amount of returned material is higher. The amount of returned material directly affects the output and quality. The product has less particles, more powder and larger amount of return material, which directly affects the output. Large particles return more materials, directly affect the smoothness and roundness of the product.

Several basic granulation methods of NPK fertilizer

Mixing granulation of different NPK fertilizers is the core of compound fertilizer processing. Fertilizer production line generally uses the following methods to granulate:

1. Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing. The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller granulator.

2. Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate. Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles. This method is used in disc granulator and rotary drum granulator.

3. Crushing granulation, which is to crush the block material into particles of appropriate size.

4. Melt granulation, which is a method of cooling and hardening molten liquid for granulation.

5. Spray granulation. It is a method of directly forming granules after concentrating the solid in the liquid.

6. The method of crystallization and granulation in liquid phase is to make materials precipitate and crystallize in liquid phase, at the same time, agglomerate into spherical particles by the action of liquid bridging agent and agitation. This technology is widely used in pharmaceutical industry. Because the shape of the particles is spherical, it is also called spherulite granulation, which is called spherulite granulation for short. Spherulite is a kind of spherical particle formed by the crystallization and aggregation of pure materials. It has good fluidity, filling and compression formability. In recent years, the technology has been successfully applied to functional pellets.

How to prevent organic fertilizer facilities from rusting in rain

Fertilizer machine is valuable. After we buy organic fertilizer equipment, we should also pay attention to maintenance in daily use. Rust is a problem often encountered by the organic fertilizer production equipment, especially in rainy days. Although the machine is not exposed to rain, it will still find rust when it is used later. What should be done in this case? Let’s explain how to prevent the fertilizer facilities from rusting in rainy days.

There is more rain in autumn. In rainy season, people will store the organic fertilizer equipment in the designated place as usual, but when it is reused after rainy day, it will be found that the organic fertilizer equipment is rusty, some mechanical parts are aging, and some parts are wet. Therefore, in view of these problems, how to keep the organic fertilizer plant in rainy days is very important.

1. Rust proof iron work. At present, the use of organic fertilizer production facilities and most of the accessories are made of iron. They are not well preserved, easy to rust and shorten the service life. The machine should be painted with antirust paint and stored in a ventilated and dry place. It is better to set up canopy for compost turning machine.

2. Anti aging of rubber parts. When the rubber parts of the organic fertilizer production equipment are damped or stained with oil, they are easy to age and crack, thus shortening their service life.

3. Protect the motor from moisture. The motor of the organic fertilizer granulator is not used for a long time, and it should be placed in a ventilated, dry and clean warehouse. If the motor is placed in the fertilizer wetland or the place easy to be wet by rain, the motor will be damped and the insulation performance will be reduced, which has caused short circuit, electric leakage, ironing and even burning coil.

The above is a simple way to prevent the equipment from rusting. As for NPK fertilizer production line and other heavy machinery, we should pay more attention to the maintenance and do a good job in the daily maintenance of the equipment, which is conducive to prolonging the service life of the fertilizer equipment and reducing the number of failures of the organic fertilizer equipment in use.
