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.

Pushing and fermentation scheme of organic fertilizer turner

We may be a little unfamiliar with the organic manure composter. In the equipment for making organic manure from livestock manure, the key equipment is the organic manure composter. The composition of its materials and main parts has a very important impact on the treatment of livestock manure. Here is a brief introduction to the fertilizer pushing and fermentation scheme of the organic fertilizer turner and the advantages of organic fertilizer from chicken manure.

Fertilizer pushing and fermentation scheme of organic fertilizer turner:

  1. Firstly, the chicken manure or other livestock manure, domestic garbage and other fertilizer making base materials shall be stacked on a flat ground in a strip heap: the pile width shall be equal to the width of the equipment, the height shall be as high as possible, and the length shall be as long as possible if the site is feasible, such as 100m, 50m, etc; The ground should be flat, and cement, brick and land can be used (as long as it is flat and has a certain hardness). The production of 10000 tons of fertilizer requires 5-6 mu of site.
  2. Add the stacked chicken manure (other livestock manure or domestic garbage) to the biological starter (strain), with 1kg of starter (strain) per ton of fertilizer base material.
  3. The straw, chicken manure (pig, cattle, sheep and other livestock manure, filter mud, sludge, domestic garbage and other agricultural and animal husbandry organic solid wastes, with a water content of 50% – 70%), starter, etc. shall be uniformly mixed and stirred with a dumper. It can deodorize in 3-5 hours, heat up to 50℃in 16 hours, and turn over again to increase oxygen when the temperature reaches 60-65 ℃. After that, when the temperature in the pile reaches 60 ℃ – 65 ℃, the pile will be turned over to achieve the effects of uniform fermentation, oxygen enrichment and temperature reduction, and the last process will be repeated until it is decomposed.
  4. If the water content of chicken manure is too high, you can use the method of reflux to put the last dried fertilizer on the bottom to form a strip, and put chicken manure in the middle, so that the water on the top can be soaked to the bottom and then turned over.
  5. Generally, the process of fertilization takes 7-10 days.

double roller granulator is applicable to various NPK fertilizer production lines

The rotary drum granulator can form powder materials through wet granulation process, which is suitable for the production of various NPK fertilizers.

Through the use of steam, the drum granulator improves the temperature and viscosity of the material, so that the moisture content of the material can be reduced in the pelletizing process, thus reducing the drying load, and the liquid phase distribution of steam is more uniform than that of adding water. Only when the liquid phase of the material is insufficient and the material is unstable, water can be added as a supplementary means.
The design of compound fertilizer production by rotary drum granulator is that steam pipe is buried in the material bed, and sprinkling water pipe is arranged above the material bed. Under the condition of stable production and supply, saturated steam can provide heat and part of water to humidify materials.
In the process of NPK production line treatment, we have encountered that due to unreasonable installation of steam nozzle and uneven distribution of material liquid phase, the place where there is more liquid phase of material will stick into big ball, and where there is insufficient liquid phase, the material is difficult to form ball, which affects the formation of particles. In view of this situation, we can increase the steam nozzle to increase the steam receiving area of the material.

Benefits of fertilizer production line using organic fertilizer granulator to process fertilizer

The actual utilization rate of chemical fertilizer in many areas is only 30% – 45%, and even lower in some areas! After applying organic fertilizer, due to its beneficial biological activity, the soil structure was improved, the soil water and fertilizer retention capacity was increased, the loss of nutrients was reduced, and the effective utilization rate of chemical fertilizer was increased to more than 50%. In addition, it can also reduce the amount of chemical fertilizer and fertilizer cost.

With the development of agriculture and the improvement of fertilizer production line technology, agricultural crop production began to reduce the use of pesticides and fertilizers. Organic fertilizer is mainly used for fertilization. Now, the use of fertilizers and pesticides has been greatly reduced. Grain production has increased and the quality is much better than before. Therefore, “organic fertilizer as the main, chemical fertilizer as the supplement” is the most reasonable fertilization method at present!

Benefits of organic fertilizer granulator machine processing fertilizer auxiliary chemical fertilizer

Benefit 1: the nutrient content of chemical fertilizer is high, the fertilizer efficiency is fast, but the duration is short, and the nutrient is single. On the contrary, organic fertilizer and chemical fertilizer can learn from each other to meet the nutrient needs of crops at different growth stages.
Benefit 2: after the chemical fertilizer is applied into the soil, some nutrients are absorbed or fixed by the soil, which reduces the availability of nutrients. The mixture of organic fertilizer and chemical fertilizer decomposed by compost t turning machine can reduce the contact between chemical fertilizer and soil, reduce the probability of chemical fertilizer being fixed by soil, and improve the availability of nutrients.
Benefit 3: the solubility of general chemical fertilizer is large, and high osmotic pressure is applied to the soil after application, which affects the nutrient and water absorption of crops and increases the chance of nutrient loss. If mixed with organic fertilizer, this disadvantage can be avoided and nutrient and water absorption can be promoted.
Benefit 4: in alkaline soil, if only acid fertilizer is applied, after plants absorb ammonium, the residual acid roots combine with the hydrogen ions in the soil to form acid, which will increase the soil acidity and harden the soil. If mixed with organic fertilizer, it can enhance the buffer capacity of soil, effectively adjust pH value and prevent the increase of soil acidity.
Benefit 5: organic fertilizer is the energy of microbial life, and chemical fertilizer is the inorganic nutrition for microbial growth and development. The mixture of the two can promote the activity of microorganism and the decomposition of organic fertilizer. Soil microbial activities can also produce vitamins, biotin, nicotinic acid, increase soil nutrients, improve soil vitality, and promote crop growth.

Precautions for application of organic fertilizer tipper

The function of the organic fertilizer tipper is to control the temperature and water, and eliminate the harm of organic fertilizer in the fermentation process. Advanced organic fertilizer tipping machine technology, no dead angle tipping. Pay attention to fermentation time, process and proportion. Next, I will introduce the matters needing attention when using the organic fertilizer tipper.

  1. When using theorganic fertilizer fermentation dumperfor fermentation, ensure that the bottom of the material is ventilated and oxygen is supplied during composting. In the process of ventilation, on the one hand, it can supplement oxygen for compost materials. On the other hand, it regulates the material moisture, and on the other hand, it controls the temperature.
  2. When the organic fertilizer fermentation dumper is used for fermentation, the organic fertilizer composting depth in the organic fertilizer fermentation tank is 0.8-1.5m. The pile width shall strictly comply with the process design of the fermentation tipper. The proper length can be determined according to the planned annual output. The compost depth is not high, which is unfavorable to temperature rise, fermentation and complete decomposition. If the depth is too large, it will exceed 2m. It is easy to cause insufficient ventilation and oxygen supplement, which also affects the fermentation quality.
  3. When using the organic fertilizer fermentation tipper for fermentation, if the materials are stored for too long or there are too many straws, fresh feces should be added for adjustment during fermentation. How long the materials are stored, it is easy to cause the dissipation or volatilization of some organic matter.
  4. When using the organic fertilizer fermentation tipping machine for fermentation, in the process of professional organic fertilizer production line, the tipping machine should be used to turn the pile. Promote fermentation and control the temperature of compost. It can control the moisture, dry and wet, and replenish oxygen, so as to achieve full maturity.
  5. When using the organic fertilizer fermentation dumper to ferment, the initial fermentation maturity is generally 10 days to half a month in the fermentation process. In this process, the main purpose is to achieve maturity, and the organic fertilizer raw materials after tank fermentation usually need secondary aging and fermentation. The second fermentation lasts from three to four days to a week.
  6. Different organic fertilizer raw materials are processed, fermented and decomposed differently during fermentation with organic fertilizer tipper

(1) Fermented with weeds and crop stalks (decomposed in about 25 days): crushed or chopped weeds and crop stalks (generally 3-5 cm in length) can be adjusted with 40% fecal water or biogas slurry. It can also be adjusted with 2% urea (46% nitrogen content) or compound fertilizer with equivalent nitrogen content. It can also be adjusted by adding fresh livestock manure according to the weight ratio of 3:1-4:1.

(2) Fermentation with pure excrement (it can be decomposed in about 20 days): it is appropriate to add crushed (chopped) weeds, crop straw for fermentation, and adjust the compost water content to about 60%, and the weight ratio is usually 3:14:1 to adjust fermentation.

(3) Fermented with manure (it can be decomposed in about 15 days): after directly expanding the volume of bacteria, evenly remove a layer in the enclosure. Stir it and directly pile it on the fermentation platform. Repeat the operation. If the water content is too large, add a proper amount of crushed dry auxiliary materials in the enclosure to adjust.

Why is the dryer often used to treat fertilizer in the production of cow manure organic fertilizer

Poultry manure is increasingly polluting the environment. However, cow manure is rich in nutrients and trace elements and is a good organic fertilizer. The fertilizer production line develops cow dung as a compound organic fertilizer, which can not only turn waste into treasure, but also reduce environmental pollution and prevent the spread of diseases, which has good economic and social benefits.

Our fertilizer granulator machine price is low, and the dryer is of high quality and low price. There is a section of secondary granulation area at the front of the dryer, and the material can realize secondary granulation in this section. Then the material is lifted up by the lifting plate to fully dry the material. The tail of the dryer draws out the moist hot air through the pipe through the exhaust fan, and enters the settling chamber to settle. After passing through the settling, the exhaust gas passes through the washing tower to spray dust and spray water. It is pumped out by a water pump for recycling, and after the second dust reduction treatment, the exhaust gas is discharged into the atmosphere through the chimney.

The main features of the dryer machine are as follows

1. Cow dung dryer has high degree of mechanization, large production capacity and continuous operation.
2. The organic fertilizer machine has an excellent and simple structure, and the material runs smoothly through the resistance of the cylinder and is easy to operate.
3. The cow dung dryer has fewer failures, low maintenance costs and low power consumption.
4. Wide application range and good product drying uniformity.
5. Sterilization and deodorization can be achieved while drying.

How to Solve the Problem of Material Agglomeration in Organic Fertilizer Fermentation

Use a compost turning machine to process fermented materials. During the composting process, technologies such as adjusting the carbon to nitrogen ratio, controlling the stack temperature, ventilation and moisture can be used to deodorize. The animal manure treatment in the farm has been mechanized, which solves the environmental pollution problem caused by the farm. The fertilizer granulator processes the compost and obtains more benefits.

In water management, if there is less water, the frequency can be reduced to prevent the slow down of fermentation speed and the decrease of microbial activity. If the turning frequency of the compost turning machine is high, the fermentation facilities can be closed to reduce heat dissipation, or the outer wall of the fermentation facilities can be built with insulation materials to maintain the temperature, or other heat sources can be used to heat up to prevent the temperature drop.
Caking of fermentation materials: there are large parts of fermentation materials in the heap, and the structure is inconsistent.
Possible causes and solutions:
1. The raw materials are not mixed evenly or the compost turning machine is not enough. Improve the original mixing method.
2. Uneven air flow or insufficient air circulation: sorting or crushing compost to improve air distribution.

What are the advantages of chicken manure organic fertilizer production line in processing fertilizer

At present, the actual utilization rate of chemical fertilizer in China is only 30% – 45%, even lower in some regions! After the application of organic fertilizer, the beneficial biological activity improves the soil structure, increases the soil water and fertilizer conservation capacity, thus reducing nutrient loss, and increasing the effective utilization rate of chemical fertilizer to more than 50%. It can also reduce the amount of chemical fertilizer and the cost of fertilization. Since the 1970s and 1980s, the UK, France and Japan have reduced the use of pesticides and fertilizers. Organic fertilizer is the main fertilizer. The use of chemical fertilizers and pesticides has been greatly reduced. The grain output has increased and the quality is much better than before. Therefore, the fertilization method of “giving priority to organic fertilizer, supplemented by chemical fertilizer” is a reasonable fertilization method at present!

More and more farmers are looking for ways to produce organic fertilizer as the organic movement continues to grow. While there are many commercial products available, some farmers are choosing to make their own fertilizer using organic production equipment.
