High efficiency and high quality controlled release fertilizer has a broad market space

fertilizer granulator Jan 30, 2023

1. High quality controlled release fertilizer is a special fertilizer for vegetables and fruits.

Vegetables, fruits and other products are high-value agricultural products, in the international market price competitiveness is strong, so vegetables, fruit crops in the special fertilizer demand is larger.

2. Industrial organic fertilizer.

Long term partial application of chemical fertilizer can easily lead to the decline of soil organic matter and the decline of crop quality, such as melon is not sweet, rice is not fragrant, vegetables are tasteless, etc. One of the key measures to improve the quality of agricultural products is to apply more organic fertilizer. The organic fertilizer processed by compost turning machine has high fertilizer efficiency, and has gradually replaced other fertilizers and become the main force of fertilizer industry.

It is expected that the organic and inorganic compound fertilizers in the future will be mainly organic fertilizers (containing more than 70% organic matter). A small amount of inorganic fertilizers will be transported to the places where organic fertilizer resources are concentrated, and granulation will be carried out by rotary drum granulator to adjust the proportion of nitrogen, phosphorus and potassium in organic fertilizer or increase the quick acting nitrogen in organic fertilizer.

3. Efficient controlled release of fertilizer.

In the future, chemical fertilizer will not only develop in the direction of high concentration and high quality, but also in the direction of high utilization rate, energy saving, and multi-functional compound. The main development direction of high-efficiency fertilizers is the production of slow-release and controlled-release fertilizers and fertilizers and foliar fertilizers mixed with nitrification inhibitors or urease inhibitors. The processing of the high-efficiency NPK production line is mainly granulation, which requires roller granulator, drum granulator, organic fertilizer granulator, flat die pellet mill and other equipment.

The dissolution rate and nutrient release rate of high-efficiency and high-quality release fertilizer can be controlled, which can maximize the utilization rate of fertilizer. Due to the extensive use of controlled release fertilizer in developed countries, the utilization rate of chemical fertilizer is more than 60%. Therefore, there is a broad market space for high-efficiency and high-quality controlled release fertilizer.

How much will it cost to set up an organic fertilizer production line in the countryside to process fertilizer?

fertilizer granulator Jan 30, 2023

China is a large agricultural country, with an effective land planting area of more than 3.1 billion mu, and a large demand for fertilizer. With the rapid development of social economy, people’s awareness and requirements for organic and green food are gradually increasing, and the development of organic agriculture and ecological agriculture is also gradually increasing. The application of chemical fertilizer in agricultural production has led to soil hardening and degradation of agricultural product quality, resulting in low crop yield. Therefore, the State encourages the use of organic fertilizer and has issued relevant subsidies and preferential policies, which has promoted the development of the organic fertilizer industry, and also brought good development opportunities and good market prospects to the organic fertilizer industry.

The factories that set up an organic fertilizer equipment production line to process fertilizer in the countryside are generally privately built, so a small organic fertilizer equipment production line with an annual output of about 10000 tons is sufficient to meet the sales demand. The primary focus of the organic fertilizer processing is the purchase of raw materials, and the most simple and small production line of organic fertilizer is raw and auxiliary materials:

Organic main raw materials: livestock manure, domestic sludge, domestic garbage and other solid wastes account for about 50-80% of the formula;
Inorganic main raw materials: urea, ammonium phosphate, superphosphate, calcium carbonate, potassium chloride, potassium sulfate, etc. account for about 10 to 30% of the formula;
Medium and trace element additives account for about 10% of the formula;
The bio-organic compound fertilizer also needs to add biological bacteria powder: 5 ‰ – 10%;
Other raw materials that may be used as required: peat, oil residue, fly ash, etc;
Auxiliary energy: water, electricity and coal.

Purchase organic fertilizer processing raw materials, chicken manure, pig manure, sheep manure, cow manure. These raw materials are not expensive, and the purchase price can be cheaper.

The investment of small organic fertilizer production line is between 80000 yuan and 120000 yuan. The main equipment of the small-scale organic fertilizer equipment production line includes fermentation tipping machine, pulverizer, granulator, screening machine, automatic weighing and packaging machine, etc. This series of small organic fertilizer production line has not only high cost performance, but also high efficiency, good energy saving and simple operation for workers.

NPK fertilizer production line uses drum granulator to adjust pH value

fertilizer granulator Jan 30, 2023

In the process of compound fertilizer granulation by rotary drum granulator, the pH of material is a main factor of fertilizer granulation, and also has an important impact on fertilizer efficiency and NPK production line.

PH is an important indicator of whether the material system is suitable. In the granulation system of ammonium phosphate, the pH value of material should be controlled between 6.0 and 6.5. When the material is slightly acidic, the solubility of the material is large, and the reaction is violent. It is easy for particles to bond into balls and produce large particles. If it is slightly alkaline, the ammonia loss is large, the reactivity of the material is poor, and the material divergence is not easy to form granules. During the operation of the rotary drum granulator, the pH value can be adjusted by adding ammonium bicarbonate and calcium magnesium phosphate fertilizer. If the conditions permit, a small amount of gas ammonia and granulation steam can be added into the material layer to neutralize map, and the reaction heat can increase the granulation temperature at the same time.

Difference between organic fertilizer equipment and npk fertilizer granulator equipment

fertilizer granulator Jan 30, 2023

When selecting organic fertilizer equipment, we should pay attention to the annual output, organic raw materials, compost fermentation mode, and the degree of mechanization of the compost turning machine. These are the key factors for organic fertilizer processing. In short, organic fertilizer production is a relatively complex process, but the risk is relatively small. If all aspects are mature, it can bring huge profits to the enterprise. The following describes the difference between organic fertilizer equipment and inorganic fertilizer equipment.

Organic fertilizer production equipment and inorganic fertilizer equipment are different, organic fertilizer equipment is mainly divided into two parts, fermentation part and production granulation part. There is also a big difference between the production of granulation part and inorganic fertilizer part, because organic raw materials and inorganic raw materials are different, the production of inorganic raw materials can be processed according to the formula of raw materials, mainly chemical reactions. If the compound fertilizer formula is appropriate and the operation is skilled, the pelletizing rate of rotary drum granulator is very high, and the production is relatively easy.

Even if the fermentation of organic fertilizer raw materials is better, granulation is relatively difficult, because the characteristics of organic raw materials are that the raw materials are light, rough, and the bonding rate is relatively low, and various organic raw materials have different characteristics. Therefore, the selection of organic fertilizer granulator machine should be particularly careful, otherwise it will not only affect the output, but also make the appearance of the product is not beautiful.

The internal quality of organic fertilizer mainly depends on the fermentation part and the formula of the product. The key factors in the fermentation part include: microorganism, C / N ratio, C / P ratio, water content, pH value and aeration control. If one of the factors is not well controlled, the fermentation will be affected. Either the fermentation is not carried out, or the fermentation is incomplete or the fermentation time is long. Therefore, fertilizer plants usually use compost turning machine to cut the yeast to ensure smooth fermentation.

The process of making biological fertilizer by organic fertilizer production line

fertilizer granulator Jan 30, 2023

The process of making biological fertilizer by organic fertilizer production line

The ground noodle pile, the ground dumper, or the fermentation tank to put materials, and the trough dumper.
Evenly sprinkle the organic fertilizer starter, and turn over the pile for fermentation to reach the temperature rise, deodorization, maturity, and killing miscellaneous bacteria grass seeds.
Fermentation lasts for 7-12 days, and the number of turns varies according to the temperature in different places.
Completely ferment and decompose, and leave the pond (ground type is directly collected by forklift).

5 Use a grading screen to screen the coarse and fine (the screened powdered fertilizer can be sold directly).

6 Crush the screened large pieces with a pulverizer and return to the grading screen.

For raw material mixing, the quantity of each raw material shall be added in strict accordance with the requirements of technical personnel, and various raw materials shall be added in the electronic belt scale or batching machine.

8 Crushed raw materials enter the aggregate belt conveyor, and then granulate with a granulator.

It is fed into the livestock and poultry organic fertilizer dryer, which adopts the method of cylinder edge transmission, flange connection and direct heat transfer, and is applicable to the drying of compound fertilizer after granulation.
Enter the cooler for cooling. The rotary cooler is mainly used for cooling the dried compound fertilizer products. It can directly cool the hot granular fertilizer to close to normal temperature.

11 After screening again, the separated large particles are broken by the large particle crusher and enter the return belt together with the separated fine powder, and then return to the granulator for granulation.

12 Lift the finished product into the material box on the packaging machine through the belt conveyor, and discharge it into the scale body according to the set weight for automatic weighing operation, and finally package and sell the finished product.

Each production line has its own characteristics. What kind of organic fertilizer is suitable for production depends on what kind of organic fertilizer equipment is needed. For example, the production line of disc and rotary stirrer must be equipped with a drying cooler, which uses hot air to dry the organic fertilizer, and then uses a cold air extraction system to cool the organic fertilizer, so that the hardness of the particles produced will be better. Users can customize appropriate configurations according to their needs. The organic fertilizer production line also has different equipment configurations according to different raw materials, and can also make appropriate plans according to the investment budget. The price of the organic fertilizer production line with different output is also different. The investment in building a large-scale organic fertilizer production line is not small, but the return on profits is also considerable. The operating effect is good for two years, and it can almost return the cost.

Fermentation time of compost treatment in organic fertilizer production line

fertilizer granulator Jan 30, 2023

In the process of organic waste treatment in fertilizer production line, fermentation is needed for a certain period of time. Most organic fertilizer products are only composted and fermented for 15-20 days, which can only meet the harmless standard. So how long does it take to ferment to get high quality organic fertilizer?

The fermentation process of high quality organic fertilizer compost generally takes 45-60 days. This is because during the heating stage and high temperature stage of composting, harmful microorganisms such as plant pathogenic bacteria, insect eggs and weed seeds will be killed, but the main role of microorganisms in this process is metabolism and reproduction, and only a small amount of metabolites are produced, and these metabolites are unstable and not easy to be absorbed by plants.

Moreover, in order to make the fermentation of high quality, it is necessary to use the compost turning machine to process the materials. Moreover, it is more convenient to stir fermentation compost with organic fertilizer flipper and save manpower. When turning over and throwing, the materials stay on the pallet for a long time, disperse at high position, fully contact with air, and easy to drop moisture. A removable wear-resistant curved tooth blade is installed on the flip-flop support plate, which has strong crushing ability for materials when taking materials. Moreover, the materials in the trough are transported to a high position of 3m through the chain plate and then continuously dropped downward. The material movement track is long and fully contacted with the air in the process of overturning, which not only improves the oxygen supply time of materials, but also facilitates moisture volatilization, and promotes the rapid completion of aerobic fermentation. It is very suitable for occasions with large processing capacity, humid climate and continuous fermentation.

After the compost passes through the high temperature stage, the microorganisms will humusify the organic matter in the later cooling period, and in this process will produce a large number of metabolites beneficial to plant growth and absorption. So it needs post-corruption. The decomposed humus is used as a raw material to be mixed with other fertilizers, and then high-quality fertilizer products are made through rotary drum granulator.

Material preparation process and allocation budget of large organic fertilizer production line with an annual output of 150000 tons

fertilizer granulator Jan 30, 2023

In recent years, in order to further protect the ecological environment and reduce air pollution, the state advocates the use of chicken manure, cow manure, pig manure and other livestock manure to make organic fertilizer instead of chemical fertilizer. In addition, the state will have corresponding preferential policies and subsidies for the purchase of organic fertilizer or the purchase of organic fertilizer production equipment. With the policy support and subsidy amount, many large farm owners and farmers’ friends have purchased organic fertilizer in succession, greatly increasing the domestic market demand for organic fertilizer, thus increasing the purchase rate and demand for organic fertilizer equipment. The establishment of organic fertilizer equipment and fertilizer processing plant has paid off handsomely. Especially in the countryside, there is a huge shortage of organic fertilizer equipment. To set up an organic fertilizer processing plant in the countryside can collect livestock manure from farmers for processing. How much is it to set up a large organic fertilizer production line with an annual output of 10-20 million tons?

A complete set of large-scale livestock and poultry organic fertilizer production lines with an annual output of 10-20 million tons include: forklift feeder, trough stacker, vertical crusher, drum screening machine, dynamic batching machine, granulator, round throwing machine, dryer, cooler, coating machine, automatic quantitative packaging scale.

First, use the dehydrator to control the water content of poultry and livestock excrement to less than 85%, and then add straw powder, rice bran, corn flour and other auxiliary materials. After fully mixing with the mixer, use the forklift to shovel it into the fermentation tank, and use the organic fertilizer tipper to fully ferment and ripen; The conveyor belt between the equipment is used to transport the particles to the pulverizer for crushing, and then to the organic fertilizer granulator for granulation. The produced particles have high moisture content, and then enter the cooler after being dried by the dryer to cool the particles and improve the particle strength. Then it is sent to the drum screening machine to screen out unqualified particles for secondary granulation, and then it is packaged with a packaging machine to produce finished products.

Maintenance method of common equipment in NPK fertilizer production line

fertilizer granulator Jan 30, 2023

1. Dust is one of the factors that cause equipment wear on the NPK production line. Fertilizer production equipment generates dust during operation. If it is not cleaned and maintained in time, dust will enter various joints of the equipment. As time goes by, the friction at the joints of the equipment will increase, which will affect the performance of the equipment. Therefore, apart from using fertilizer equipment, we must conduct a comprehensive inspection and maintenance of the equipment.

2. During the operation of the NPK production line, staff also need to pay attention to the degree of lubrication of the equipment joints. The long-term use of equipment is a severe test of equipment lubrication. Once the jam occurs, the friction of the equipment will increase. Only with a high degree of lubrication can the operation of the equipment be supported by good power and be cleaned regularly.

3. We need to pay special attention to the motor friction of the fertilizer granulator and related equipment. Motor wear will affect the use of organic fertilizer equipment. The staff should pay attention to checking the operation of the motor at all times. Especially before the load is running, the circuit of the motor should be checked, and if it is damaged, it needs to be updated immediately.

Precautions for use of NPK mixed fertilizer granulator

fertilizer granulator Jan 30, 2023

During the operation of NPK production line, the fertilizer mixer and other equipment should be checked frequently. In case of abnormal noise, impact, vibration and sharp temperature rise, it should be checked immediately and the operation can be continued after troubleshooting.

1. Before commissioning the mixer, add gasoline or kerosene, clean the parts in the tank and oil pool after running, and then add gear oil and put it into operation.

2. Before commissioning, manually climb the belt pulley to make the main shaft idle for several weeks, and start it only after confirming that there are no obstacles and abnormal phenomena.

3. When starting the main engine, it is necessary to wait for the motor to reach the rated speed, and then make the clutch combine slowly. Do not use too much force to damage the parts and reduce the service life of the machine.

The major repair and maintenance of fertilizer mixer is carried out once a year, and the medium maintenance is carried out once a month. All mechanical sliding parts must be added with grease to ensure the flexibility of equipment operation. The normal treatment of the fertilizer mixer can make the raw material conform to the processing of the fertilizer granulator.
