Conventional production methods of granular fertilizer:conventional production methods of granular fertilizer are divided into extrusion method and aggregate method.
The ring die granulator,flat die granulator and roller press granulator are used in extrusion granulation.During the granulation process,the ring die granulator machine and template are severely worn,with short service life,high maintenance of fertilizer granulator machine price and large power consumption. 



Moreove,the extruded particles are cylindrical or flat die granulator machine,with poor fluidity,so they are not suitable for mechanized fertilization.The pelletilizer and drum granulator are used for pelletilizing.They are used to crush the dried organic raw materials and chemical fertilizer into fine powder,and then use the disc granulator or rotary drum granulator to roll the materials into granules.

How to build a fully automatic organic fertilizer production line in the farm

The scale of livestock farms in China is becoming larger and larger, and the feces produced every day are difficult to be treated. The feces of livestock and poultry farms are treated innocuously through the equipment of the production line for processing organic fertilizer in livestock and poultry farms, and the feces of livestock and poultry farms are comprehensively utilized to prevent the pollution of the feces to the environment, while promoting the sustainable development of the aquaculture industry.

The production of organic fertilizer by livestock manure fermentation requires good (consumption) oxygen fermentation. Therefore, the oxygen supply measures should be increased during the operation process, so as to achieve uniform mixing, frequent turnover and ventilation. Otherwise, it will lead to anaerobic fermentation and odor, affecting the fertilizer effect. Fermentation is complete. Generally, 48 hours after pig manure is piled up, the temperature rises to 50~60 ℃, and the temperature can reach above 65 ℃ on the third day. At this high temperature, it will be overturned once by the organic fertilizer fermentation tipper. Generally, there will be two times of high temperature above 65 ℃ during the fermentation process. The fermentation can be completed after two times of overturning, and the fermentation can be completed within a week or so normally. The material is dark brown, and the temperature begins to drop to normal temperature, indicating that the fermentation is complete.

The complete set of equipment configuration includes fermentation equipment, pulverizer, mixer, granulator, dryer, cooler, screening machine, coating machine and packaging machine, as well as conveyors for material transportation between equipment. Such a complete set of equipment configuration needs 23 million, but the entire production line only needs five or six workers to complete the production operation and realize automatic production.

Among them, the reasonable collocation of the fineness of raw materials is crucial for the production process of organic fertilizer. The fineness of the whole raw material should be matched as follows: 100-60 mesh raw material accounts for about 30-40%, 60-mesh raw material accounts for about 35%, and small particles with diameter of 1.00-2.00 mm account for about 25-30%. The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the particles after granulation. However, in the production process, the use of super proportion and high fineness materials is easy to cause problems such as oversized particles and irregular particles due to poor viscosity.

Composting is a treatment technology for organic components in organic fertilizer production line with organic fertilizer machine. The wastes such as stone, metal and glass not only affect the fermentation process of compost, but also affect the quality of compost. These substances must be sorted out and treated separately. At present, China’s urban domestic waste generally adopts a mixed collection method. Although the paper, plastic, etc. in the garbage are greatly reduced after multiple pick-ups by residents, scavengers, sanitation workers, etc., the garbage still contains some non-degradable substances such as metals and waste batteries , Waste lamps, etc.
At present, in the process of composting, the method of mechanical combined with manual sorting is usually adopted. The mechanical sorting methods mainly include screening, wind sorting and magnetic sorting. Taking effective measures to promote the separation and collection of municipal solid waste in China is very necessary to save the cost of compost and improve the quality of compost.

The fertilizer granulator machine included the rotary drum granulator machine, new type organic fertilizer machine, and roller press granulator machine. Other series organic fertilizer granulator machine are to be designed for different type. 
Zhengzhou Huaqiang as a manufacturer for fertilizer production line is willing to provide you with professional solutions and the most favorable fertilizer granulator machine price.

Applying organic fertilizer is beneficial to environmental protection. The eutrophication of the water environment in China mainly comes from the discharge of solid organic wastes into the water body, and the discharge of fertilizer nutrients from farmland only accounts for a small proportion. At present, the eutrophication degree of the water environment in China’s lakes is still very serious. For Taihu Lake, Dianchi Lake, Chaohu Lake, Dongting Lake, Poyang Lake and other lakes, cutting off the input of organic and inorganic nutrients into the water body is the only way to achieve the prevention and control of water eutrophication. The development of organic fertilizer industry and the protection of water environment in the development of fertilizer industry is a great cause that combines fertilizer industry, soil fertility and water environment protection, high quality and high yield of crops.

The process flow of manure organic fertilizer production line is as follows: after the fermentation of organic fertilizer raw materials (animal manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.), they enter the semi-wet material crusher for crushing, and then add nitrogen, phosphorus and potassium (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make the mineral elements meet the required standards, and then have a mixer to stir, and then enter the organic fertilizer granulation mechanism particles, and then dry after coming out, The qualified products are screened by the screening machine and packed. The unqualified products are returned to the granulator for granulation.

Applying organic fertilizer is one of the main ways to improve soil fertility. Soil is the main natural resource of agricultural production, and crop production can fundamentally be said to be soil production. Due to its high microbial activity, high-fertility soil has a stronger ability to eliminate environmental pollution, so that sudden pollution events will not immediately or to a greater extent pollute agricultural products, or even enter the food chain and endanger human health. High fertility soil can also significantly improve the quality and flavor of agricultural products and significantly prolong the fresh-keeping period of vegetables and fruits due to its strong ability to coordinate soil water, fertilizer, air and heat, continuous and stable nutrient supply, and strong soil microbial and enzyme activity, which is the theoretical basis for organic fertilizer and production of “delicious food”.

More application of bio-fertilizer and organic fertilizer will help to change the thinking method of fertilizer application and seeding method of chemical agriculture, and then guide farmers to embark on an ecological and organic agricultural development path with Chinese characteristics.

How can agricultural producers avoid inferior fertilizer and buy high quality compound fertilizer? Fertilizer granulator manufacturers guide you in the following ways.

3. Burn

Nowadays, organic fertilizer has been loved by cash crop growers all over the country, and plays an indispensable role. Bioorganic fertilizer contains a large amount of organic matter, which is an important source of organic matter in soil. It can improve soil, improve soil fertility, turn lean soil into fertile soil, and turn bad soil into good soil. Because soil organic matter forms humus through the action of microorganism and physical chemistry, it can promote the formation of soil water-stable aggregate structure, make cohesive soil loose and easy to cultivate, and sandy soil become structured.

Taking livestock and poultry manure as an example, the annual output of 5000 tons of granular organic fertilizer equipment investment, production cost and benefit analysis.

Input cost of organic fertilizer production line:

1. Plant: at least 500 square meters, including fermentation tank area, raw material manure stacking area, fermented organic fertilizer processing and packaging area, finished organic fertilizer stacking area, etc. The plant does not need good materials, but its height is at least 5 meters, and the construction cost per square meter is about 350 yuan.
2. Fermentation of livestock and poultry excrement: build a relatively large excrement treatment station in a large-scale (one machine with multiple tanks) centralized breeding area. The daily treatment of livestock and poultry excrement is more than 12 tons, with a 3M span trough tipper, and the unit price is 26000 yuan/set; Build a 300-500 square meter transparent greenhouse, with several fermentation tanks built in the greenhouse (the cost depends on the local actual situation due to different materials).
3. Tipper: fixed rail type tipper: the price of the tipper is about 15-200 yuan, and the cost of the line, rail and installation is about 30000 yuan. Two fermentation tanks share one tipper (including exchange equipment); If a walking tipping machine is used, the price of each machine is 6-150000 yuan, but it can be directly stacked on the ground for fermentation without building a fermentation tank.
4. Forklift: This is a necessary equipment to improve efficiency. Small-sized forklifts are generally priced at 6-150000 yuan. You can buy second-hand ones, generally around 30000 yuan; At present, there are also walkable tipping machines+forklifts in one, with a price of 55-1200 (different specifications).
5. Organic fertilizer crusher: the fermented organic fertilizer is crushed to more than 40 meshes, and the finer the crushed organic fertilizer is, the more beautiful the later granulation is. The specifications with the price of 4500-200000 yuan are determined according to different output.
6. Conveyor: configure belt conveyor, bucket elevator or screw conveyor according to the actual needs of customers. According to the length of transmission, a production line generally needs two conveyor belts of about 10 meters, and the price of each belt is between 15000 and 25000 yuan.
7. The packaging machine is mainly composed of material inlet, feeding mechanism (gate), weighing bucket, bag clamping mechanism, frame, suction port, pneumatic system, sensor, control box, conveying and sewing mechanism, etc.
8. Multi-element organic fertilizer formula batching machine (equipment price is between 11000 and 18000 yuan): adjust the content of nitrogen, phosphorus, potassium, humus and organic matter of powdered organic fertilizer according to different crop requirements.
9. Formula mixer (equipment price is between 21000 yuan and 38000 yuan): fully mix and evenly mix the prepared formula elements.
10. Organic fertilizer granulator: the prepared fertilizer elements are used to agglomerate the powder into particles under the mechanical action by centrifugal granulation.
11. Dryer (equipment price is 28-1800 yuan): dry the prepared particles for storage.
12. Cooler (the equipment price is about 3.5 yuan): quickly cool the dried fertilizer particles and facilitate bagging.
13. Screening machine (equipment price is about 5-2000 yuan): classify the size of fertilizer particles, and bag them in batches according to the size of the particles.
14. Fertilizer granule coating machine (equipment price is about 20000 yuan): Apply a layer of non-caking agent on the surface of the finished granules to make the fertilizer granules not stick.

Calculation of production cost of organic fertilizer (organic fertilizer per ton of product):

1. Daily consumption of fresh livestock and poultry manure: daily output of 12 tons × 2.7 m3/t × 15 yuan/square meter=486 yuan (excluding freight), the subtotal is 40.6 yuan per ton.
2. The annual production of 5000 tons of organic fertilizer requires 100 tons of dry straw powder. (For summer use, purchased from outside) 170 yuan per ton, totaling 17000 yuan, with a subtotal of 3.4 yuan per ton.
3. The dosage of bacteria is 1/15000, 2.16 kg per day × 100 yuan=216 yuan, subtotal 18 yuan per ton.
4. The subtotal of freight is 20 yuan per ton. (transported from the breeding farm to the packaging workshop)
5. The depreciation cost of facilities and equipment is calculated as per five years (equipment and facilities, calculated as per 200000 yuan, is about 40000 yuan per year, with a subtotal of 8 yuan per ton).
6. Total wages. There are 5 workers, and the daily wage of each person is 100 yuan. The total daily wage is 500 yuan/12 tons=41.6 yuan/t, and the subtotal of each ton is 41.6 yuan.
7. Daily power consumption: 80 kWh × 10 hours/day × 0.6 yuan/degree=480 yuan, with a subtotal of 48 yuan per ton.

The total production cost per ton of granular pure organic fertilizer (with nutrient content of more than 9% and organic matter of about 75%) is about 180.0 yuan/ton.

Analysis of organic fertilizer sales income

The production cost per ton of pure organic fertilizer produced by fermentation mode is about 180.0 yuan/ton. It is adjusted according to the national organic fertilizer standard, plus the warehousing cost of packaging bags, etc. of 50 yuan/t. It is sold at the current market price of 600 yuan per ton. The gross profit per ton is 270 yuan/ton. The net profit is calculated at 50 yuan, excluding the intermediary and transportation fees. The annual sales of 5000 tons * 270 yuan/ton can earn 1.35 million yuan.

The above data are for reference only, mainly because the prices of facilities and equipment produced by different factories are different, and the costs of plant construction and labor costs are different in different places. In addition, the above is the investment required for one production of organic fertilizer. If multiple organic fertilizer production lines are built, they can be calculated by superposition, but some equipment and facilities can be shared. Therefore, the more production lines, the lower the average investment.

There are many kinds of raw materials for organic fertilizer processing. We will use organic fertilizer mixing machine when processing. The different materials mixed by the mixer and the nutrient are even, so they can be suitable for the granulation of the organic fertilizer granulator machine.

According to different raw materials, organic composting fermentation equipment can be divided into high temperature composting and ordinary composting. High temperature composting takes plant materials with high fiber content as the main raw materials, and generates a lot of heat through composting and fermentation under aerated conditions. The temperature of composting is very high (50-60 degrees Celsius). Therefore, it matures quickly, composts quickly and has high nutrient content. The following NPK production line manufacturers introduce how long it takes for organic fertilizer fermentation equipment to process.

Fermentation composting and turning of organic manure

 The process of making biological fertilizer by organic fertilizer production line

1. The ground noodle pile, the ground dumper, or the fermentation tank to put materials, and the trough dumper.
2. 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.
3. Fermentation lasts for 7-12 days, and the number of turns varies according to the temperature in different places.
4. 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.

7. 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.

9. 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.
10. 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.

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.
