Organic fertilizer equipment produces organic fertilizer and develops ecological agriculture

To develop ecological agriculture and develop and produce pollution-free “organic food”, the fertilization technology in agricultural production must be reformed, that is, to apply fertilizer reasonably, to follow the development path of organic-inorganic combination application, and to vigorously develop organic fertilizer. Benefits of using organic fertilizer:

1、 Improve soil and improve soil fertility: after applying organic fertilizer into the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, ripen the soil, enhance the ability of fertilizer conservation and supply and buffer capacity of the soil, and create good soil conditions for the growth of crops.

2、 Improve product quality and increase yield: organic fertilizer is rich in organic matter and various nutrient elements to provide nutrition for crops. After the decomposition of organic fertilizer, it can provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances that can promote the growth of crops and improve the quality of agricultural products.

3、 Improve the utilization rate of fertilizer: organic fertilizer contains a lot of nutrients and releases slowly. The organic acid produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in the soil, which is conducive to crop absorption and improve the utilization rate of fertilizer.

The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial strains are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, disc granulator, dryer, cooler, drum screening machine, film coating machine The bio-organic fertilizer produced by packaging equipment, belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, decomposition and deodorization.

Composting treatment of pig manure organic fertilizer composter

The complete set of organic fertilizer equipment needs fermentation and turning machine, organic fertilizer grinder, drum screening machine, horizontal mixer, fertilizer granulator, rotary dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.

Fermentation is the first step of pig manure organic fertilizer production. Composting fermentation is widely used in organic fertilizer production. So what are the complete steps of pig manure fermentation?
Treatment requirements of compost turning machine
1. Temperature requirements. The start-up temperature should be above 15 ℃ (it can be operated in four seasons and not affected by seasons. Fermentation should be conducted indoors or in Greenhouse in winter).
2. Materials are piled up. When doing heap, it should not be too small or too short. If it is too small, fermentation will be affected. The height is 1. The results showed that the fermentation effect was better when the length was more than 2-4 meters and 5-2 meters. Many organic fertilizer plants use fermentation tank for fermentation. The tipper can move flexibly on the track, with large treatment capacity and high efficiency.
3. Turn over the pile for ventilation. During the fermentation process, proper oxygen supply and composting should be paid attention to (overturn several times when the temperature rises to 75 ℃) and the temperature should be controlled at about 65 ℃. If the temperature is too high, the nutrients will be affected.
4. Fermentation is complete. Generally, the fermentation can be completed within a week, the material is dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete. If there are too many auxiliary materials such as sawdust, wood chips, and rice husks, the fermentation time should be prolonged until fully decomposed. After being decomposed, it is further processed by rotary drum granulator.
5. Material ratio. 1.5 tons of pig manure (about 2.5 tons of fresh manure) plus 1 kg of fertilizer starter, the starter must be mixed with rice bran (or bran, corn flour and other substitutes) in a ratio of 1:5, and then evenly sprinkled Put it into the pig manure pile and mix evenly.

What drying equipment is needed for the large output npk fertilizer production line

Working principle of drum dryer

Drum dryer is a common drying equipment in NPK production line, which is used to deal with wet fertilizer particles in fertilizer processing. The rotary cylinder of the dryer is a slightly inclined and rotatable cylinder. The wet material enters from the upper part of one end and the dry material is collected from the lower part of the other end. Hot air enters from the feed end or discharge end and is discharged from the upper part of the other end. The cylinder is equipped with a forward feed plate, so that the material can be continuously picked up and sprinkled during the cylinder rotation, so that it can fully contact with the hot air flow, so as to improve the drying efficiency and make the material move forward. The heat source of drying materials is generally hot air, high temperature flue gas, steam, etc.

Application scope of drum dryer:
1. Chemical industry, miner, metallurgy and other industries, such as ore, slag, coal, metal powder, clay, diatomite, kaolin.

Organic wastes such as peat, sludge, chicken manure, pig manure, cow manure, sheep manure, medicine residue, mushroom residue, lignite, filter sludge of sugar mill, papermaking sludge, wine, straw, bean residue, peat and other organic wastes can be directly granulated after fermentation.
Characteristics of organic fertilizer granulating machine

1. The granular material processed by bio organic fertilizer granulator has smooth surface and moderate hardness.
2. Fertilizer granulator machine price low, and has high cost performance ratio. It integrates feeder mixer and granulator into one.
3. When feeding evenly, the material is stirred for the second time at the same time. The feeder is equipped with a governor to adjust the feeding amount according to the dry and humidity of the material in production, so as to avoid the failure of the main engine.
4. The granulator mold, mixing and conveying blades are all corrosion-resistant stainless steel quenched and tempered; the pressure roller is cast with manganese and quenched and tempered to achieve corrosion resistance and wear resistance. So as to increase the output and reduce the loss of equipment.

Fertilizer advantages of biological fertilizer granulator processing

It is said that the organic fertilizer processed by the organic fertilizer granulator is good, so where is it? Bioorganic fertilizer is rich in organic matter, including nitrogen, phosphorus, potassium and other elements, as well as calcium, magnesium, sulfur, manganese, zinc, copper, boron, molybdenum, chlorine and other trace elements. Most importantly, functional bacteria can decompose mineral phosphorus in soil, decompose mineral potassium in soil, release phosphorus, potassium and other nutrients, and provide stable nutrients for crops. This may be the magic of bio-organic fertilizer!

From the use effect of many years, the organic fertilizer processed by the mechanical fertilizer granulator has achieved satisfactory results in the verification of fertilizer efficiency and various crops, and has been recognized by many people. With the rapid development of organic agriculture in China, bio-organic fertilizer shows a growing market prospect.

Seven advantages of using bio-organic fertilizer

1、 Decomposition of nitrogen, phosphorus, potassium and animal and plant residues, release of nutrients, decomposition of pesticides and herbicide compounds, reduce the use of fertilizer by 30% to 50%, and increase the utilization rate of fertilizer by about 40-60%. In addition to the high level of bio-organic fertilizer, the total input of organic fertilizer processed by mechanical fertilizer granulator will not increase, but long-term bio-organic fertilizer, which may be less than that in previous years.

2、 Yield increase: grain and oil output 10-15%, cash crop output 15-25%, fruit and vegetable output 15-40%, single variety, single fruit weight increase, fruit and vegetable early maturity and harvest period extension.

3、 It can improve the disease resistance of crops. Antibiotic bacteria can reproduce in large numbers in the soil to produce antibiotics and effectively inhibit the growth of pathogens. According to different crops, the incidence rate can be reduced by 50-80%, especially for more than 30 kinds of pathogens, including blight, verticillium wilt, sunspot disease and root rot.

4、 Drought and drought: during seed dressing or top dressing at seedling stage, the roots of crops can be developed by more than 60-200%, and the ability to conserve water and fertilizer is enhanced, laying the foundation for high yield, especially the effect of fertilizer based on carbon production is greater.

5、 Soil improvement: when the organic microorganism decomposes the organic matter, it will produce a large number of organic acids and binders, which will help to form the soil colloid and massive structure that can adjust the soil PH value. Improve the physical and chemical properties of soil, increase the structure of soil block, and reduce water evaporation.

6、 Environmental protection and green: vegetable vitamins, food protein content, full of oil and grain, add one or two pieces of fructose, and fruits and vegetables grown with bio-organic fertilizer have the flavor of childhood. Recall the taste of your childhood.

7、 Multi-year yield growth effect: after the beneficial microorganisms are applied to the soil, they continue to decompose the organic matter and crude fiber for reproduction, which means that many small fertilizer plants continue to provide nutrition for crops around the crops, relax the soil, reduce the input of fertilizers and pesticides, and improve the yield and quality of crops. The comprehensive income cannot be calculated.

How to select suitable dryer in npk fertilizer production line

In the production process of bio organic fertilizer, the moisture content of fertilizer is required to be lower than 14%. If the particles are too wet, they need to be dried. Therefore, drying is an indispensable and important process in the fertilizer production line, which directly affects the output, quality and energy consumption. It is very important to select the fertilizer granule dryer machine reasonably.

In the fertilizer production process, the fertilizer processed by the rotary drum granulator enters the dryer for drying. In order to avoid the death of effective live bacteria due to high temperature in the drying process, the temperature of hot air contacting with materials is different according to the moisture content of materials. It is suggested that the hot air temperature can be controlled in sections, which can improve the thermal efficiency and avoid the death of effective living bacteria.
Combined with these characteristics, a drum dryer suitable for low temperature and low moisture drying is selected, which can control the temperature of hot air to ensure that the material temperature is not higher than the specified temperature in the whole drying process. A cooler can be added at the tail of the machine, which can be cooled immediately after drying, which has the function of multi-purpose.

 

A section of secondary granulation area is set in the front of the rotary drum dryer for fertilizer, in which the material can realize secondary granulation. After that, the material is lifted up by the lifting plate for full drying. The wet hot air is drawn out through the exhaust fan through the pipeline at the tail of the dryer, and then enters the settling chamber for settlement. After the secondary dust reduction treatment, the tail gas of NPK production line can be discharged into the atmosphere.

Process introduction and operation method of mixer in npk fertilizer production line

The mixer is used for mixing and mixing materials to realize the balanced collocation of different raw materials. In the fertilizer production line, the thoroughly mixed materials can be granulated by the fertilizer granulator.

The fertilizer mixer should be equipped with secondary leakage protection device. After the power supply is connected, it must pass the test run without load before it can be used. During the commissioning of the mixer, it is necessary to check whether the speed of the mixing drum is appropriate. In general, the speed of the empty car is slightly faster than that of the truck (after loading). If there is a large difference, the ratio of the driving wheel and the driving wheel should be adjusted.

Uses and characteristics of fertilizer mixer:

The mixing equipment is mainly used for the mixing of raw materials. The Huaqiang mixer disc is lined with polypropylene or stainless steel, so it is not easy to stick to the material. Wear-resistant, the use of cycloid reducer has the characteristics of compact structure, convenient operation, uniform mixing, convenient unloading and conveying. The disc mixer adopts polypropylene plate lining or stainless steel plate, so it is not easy to stick to the material. Wear-resistant, the use of cycloid reducer has the characteristics of compact structure, convenient operation, uniform mixing, convenient unloading and conveying. It is used for npk production line.

Working principle of fertilizer mixer:

Start the main mixing motor, drive the mixing parts through the sprocket speed reduction drive. According to the formula set by the electronic instrument, various raw materials are respectively put into the organic fertilizer mixer through the loader or manually. Through the cooling system, various materials with good statistics are mixed, overturned, sheared and kneaded in the mixer to achieve the purpose of fully mixing various raw materials and strains Finally, the discharging motor drives the gate to open and close to realize the discharging operation. Rotary drum granulator can meet the needs of material production.
