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.

Wet granulation and its characteristics of double roller granulator

Non dry extrusion granulation technology and characteristics of double roller granulator the non dry extrusion granulation technology of twin roll extruding granulator is widely used in powder particle processing. It is characterized by direct treatment of particles without humidification or heating. It can be used for processing organic and inorganic fertilizer particles, as well as feed particles.

The non dry extrusion granulation process is adopted, so there is no waste water and waste gas emission in the production process, and the environment is not polluted. The extrusion granulation process is short, easy to operate, easy to realize automatic production control and improve production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are relatively wide.

Five technological stages of double roller granulation process for organic and inorganic fertilizers

  1. Add qualified raw materials into the mixer according to the ratio requirements, and mix evenly.
  2. It is conveyed to the disc feeder and the metal substances in the material are removed during the conveying process.
  3. The materials in the disc feeder are uniformly fed into the extruding granulator, forcing the materials to be extruded into thin sheets between two pressure rollers, crushed into pieces by a coarse crusher under the pressure roller, and then screened. The material on the screen continues to be crushed and screened.
  4. The semi-finished products are transported to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the crusher and then returned to the disc feeder.
  5. The qualified products are sent to the automatic packaging scale for weighing, packaging and warehousing.

The non drying double roller granulator has the following characteristics when producing granules:

  1. Extrusion granulation does not require heating and humidifying materials, saving investment and energy. It is also suitable for granulation of heat sensitive materials including ammonium bicarbonate and some organic fertilizers.
  2. No waste water and waste gas are discharged in the production process, and no environmental pollution is caused
  3. The extrusion granulation process is short, easy to operate, easy to realize automatic production control and improve production efficiency.
  4. There are no special requirements for the properties and particle size distribution of raw materials, so the raw materials are widely sourced.
  5. The production is relatively flexible, and the product scheme can be changed at any time, which is conducive to the small batch production of special fertilizer.
  6. The particle size distribution of the product is uniform, without segregation or agglomeration.
  7. The shape of extruded granulation products is uniform and not round. In general, if you need a more rounded product, you need to further reshape the particles.

Benefits of processing organic fertilizer with fertilizer by bio fertilizer granulator

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!

Five benefits of the combination of organic fertilizer and chemical fertilizer produced by biological fertilizer granulator! Benefit 1: The fertilizer has high nutrient content and fast fertilizer effect, but its duration 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 and meet the nutrient demand of crops in each growth period.

Benefit 2: After chemical fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, reducing the availability of nutrients. After mixed application with farmyard manure, it can reduce the contact surface between fertilizer and soil, reduce the possibility of fertilizer being fixed by soil, and improve the availability of nutrients.

Benefit 3: Generally speaking, the solubility of chemical fertilizer is large, which will produce high osmotic pressure on the soil after application, affect the absorption of nutrients and water by crops, and increase the chances of nutrient loss. If it is mixed with organic fertilizer, it can avoid the disadvantage that crops absorb nutrients and water.

Benefit 4: If acid fertilizer is only applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid root will combine with hydrogen ions in the soil to produce acid, which will lead to acid enhancement and soil hardening. If mixed with organic fertilizer, it can enhance the buffer capacity of the soil, effectively regulate the pH and prevent the increase of soil acidity.

Benefit 5: Since organic fertilizer is the energy source of microbial life, chemical fertilizer is the inorganic nutrition for microbial growth and development. The two mix the vitality of microorganisms to further decompose organic fertilizers. The activity of soil microorganisms can also produce vitamins, biotin, niacin, etc. Increase soil nutrients, improve soil vitality and crop growth.

Application field of new organic fertilizer granulator

The new organic fertilizer granulator is a special granulator for organic fertilizer. It is also known as internal rotary mixing tooth granulator, because its internal structure is composed of many spirally arranged mixing teeth. The granulator is also called wet granulator, because it is applicable to the granulation of many raw materials with high water content. It is widely used for granulation of organic fertilizer and chemical raw materials. Because of its high granulation rate, stable operation, durable equipment and long service life, it has been selected as the ideal product by the majority of users.

Working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation. The shape of the particles is spherical, the sphericity is 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is 90%. The particle diameter can be properly adjusted according to the material mixing amount and the spindle speed. The lower the mixing amount, the higher the speed, the smaller the particles, and vice versa. Scope of application: The new organic fertilizer granulator is especially suitable for the granulation of light fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of particles, and the better the quality of particles. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

In view of the particularities of granulation of organic fermentation fertilizers and organic fertilizer raw materials, such as livestock manure, manure, compost, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms and other urban domestic waste, the particles are particles. The qualified rate of granulation of the new organic fertilizer granulator is as high as 80-90%, which is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the percentage of large pellets is lower than 15%. The particle size uniformity can be adjusted through the stepless speed regulation function of the machine according to user requirements. This machine is more suitable for direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing production cost.

Operation process of organic fertilizer disc granulator

  1. Control of water content during operation of disc granulator oforganic fertilizer equipment. When the disc granulator is running, the inclined disc granulation process is adopted. The granulation process requires high moisture content, and poor moisture control will lead to the decrease of granulation speed. Therefore, in the process of processing, attention should be paid to the use of spray to observe the moisture control changes of granulating raw materials.
  2. The personnel operating thedisc granulatorshall pay attention to the quality of various materials during the feeding control process to ensure that sundries, large pieces and large particles are not mixed into the feeding. In addition, they should also pay attention to the temperature of the equipment feeding, because if the temperature of the die head is too high, the material is easy to break and stick to the die head after startup. In this case, they should wait for the die head to cool before continuing to operate.
  3. Pay attention to the change of inclination angle of disc granulator during operation. The disc granulator has a certain inclination. If the inclination angle changes due to unexpected reasons, it will also affect the granulation rate of organic fertilizer particles and the service life.
  4. During the operation of thedisc granulator, the operator shall also pay attention to the temperature change of the machine body at any time. The operator can touch the blade with clean hands. If the blade does not touch the hand, the temperature should rise immediately until the blade touches the hand. Then, during the normal operation of the granulator, the operator should maintain a stable machine temperature and not allow the temperature to rise or fall. In addition, the operator should pay attention to maintaining the temperature around the vent until the head temperature reaches about 200℃.
  5. When using the disc granulator, in order to ensure that the produced particles are uniform, smooth and complete, attention should be paid to ensuring that the feeding is uniform and sufficient. The feeding speed of the equipment should be properly matched with the feeding speed to avoid the decline of particle quality and output.
  6. When the disc granulator body is unstable, pay attention to check whether the coupling clearance is too tight and loosen it in time. If the bearing part of the reducer is hot or noisy, it shall be repaired and oiled in time.
  7. During the installation of the disc granulator, the main body shall be kept perpendicular to the horizontal plane, and the perpendicularity shall be calibrated and corrected after installation.
  8. Before the installation of the disc granulator, the concrete foundation shall be prepared, installed on the horizontal concrete foundation and fastened with bolts.
  9. Before power on, ensure that the power supply meets the power supply requirements set by the disc granulator, and configure the power cord and control switch according to the equipment power supply.
  10. After installation, check whether the bolts of each part are loose and whether the main engine compartment door is fastened.

In the process of using the organic fertilizer disc granulator, if the 10 precautions in the operation process are strictly followed, the granulation rate will be effectively improved, the energy consumption will be reduced, and the service life of the equipment will be extended.

Organic fertilizer granulator realizes green reuse of resources

China has been a large agricultural country since ancient times. It can be seen that agriculture has an irreplaceable position in China. However, the bio fertilizer granulator has greatly promoted agriculture, which shows the position of bio fertilizer granulator in China. With the acceleration of social progress and the rapid development of science and technology, people have higher and higher requirements for material quality. In the future, people will demand more and more organic products, and green products will occupy the whole market.

How to realize the green reuse of the double roller granulator resources is a problem that everyone is concerned about. On the other hand, the double roller granulator is an innovative product designed and produced under such a big premise. Why do you say that? I will give you a detailed introduction:

First of all, the double roller granulator is widely used to granulate some waste materials, such as coal powder, carbon powder, coke powder, carbon black, mineral powder, dust removal ash, lime powder and other metal mineral powder, as well as industrial recycled dust materials, iron casting plant dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust, etc.

The double roller granulator really realizes the recycling of resources and greatly protects the environment. In terms of environmental protection, the processing operation of this equipment adopts the non dry normal temperature process, which has high particle strength and is more obvious than other granulation methods, especially suitable for the occasions where the bulk specific gravity of products increases. More importantly, the mechanical transmission system of the roll extrusion granulator is completely sealed in the machine body. As the powder materials complete the granulation process in the wet state, there is no discharge of the three wastes during the granulation of the roll to roll granulator and the subsequent process operation, which truly realizes green production. The double roll extruding granulator has realized the green reuse of resources and has huge market potential.

Working principle of new organic fertilizer granulator

Working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation. The shape of the particles is spherical, the sphericity is 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is 90%. The particle diameter can be properly adjusted according to the material mixing amount and the spindle speed. The lower the mixing amount, the higher the speed, the smaller the particles, and vice versa. Scope of application: This machine is especially suitable for granulation of light and fine powdery materials. The finer the basic particles of fine powder materials, the higher the sphericity of particles, and the better the quality of particles. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. In view of the particularities of granulation of organic fermentation fertilizers and organic fertilizer raw materials, such as livestock manure, manure, compost, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms and other urban domestic waste, the particles are particles.

The qualified rate of granulation of the new organic fertilizer granulator is as high as 80-90%, which is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the big ball rate is lower than 15%. The stepless speed regulation function of the machine can adjust the uniformity of particle size according to user requirements. This machine is suitable for direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing production cost. Now this new type of wet granulator for organic fertilizer is favored by the majority of users. The birth of new products, new production processes, energy conservation and environmental protection are all trustworthy.

Main factors of pelleting rate of organic fertilizer granulator

The principle of drum granulation is that materials rely on surface tension, an appropriate amount of liquid phase, extrusion force generated by rolling between materials, and small particles are the core of materials in the correct direction of movement in the granulator, and large absorption and small attachment are made during rolling. The higher the rolling frequency within a certain period of time, the higher the balling rate will be, and the rounder the particles will be after molding.

In the production process, we have encountered two situations due to different friction between materials and the wall of the granulator. The internal surface finish of the granulator is large, which reduces the friction between the material and the cylinder wall and weakens the upward movement of the material. If the material does not roll, it will not produce particles. In view of this situation, we can solve it by adjusting the rotating speed of the granulator and installing a small board inside.

The materials in the organic fertilizer granulator are seriously sticky to the wall, and the friction between the materials in the granulator and the cylinder wall is increased, which lifts the materials too high, causing the materials to be thrown down from the top, and causing the particles to be out of round and large particles to be too many. We believe that there are two reasons for this situation: on the one hand, there are too many sticky materials in the materials, which we solve by changing the process formula and reducing the amount of sticky materials; On the other hand, the internal surface of the organic fertilizer granulator is not smooth, which can be solved by changing the internal materials and increasing the internal finish of the granulator.
