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.

Process flow of sheep manure organic fertilizer production line

The sheep dung is mainly produced by tank aerobic fermentation, which is a common method to treat sheep dung at present. It is also suitable for the commercial production of sheep dung organic fertilizer, and is conducive to standardized production. Sheep dung urine is rich in nutrients, which can be easily decomposed into effective nutrients that can be absorbed and used by crops, as well as slow nutrients that are not easy to decompose. It is a good fertilizer combining fast and slow fertilizer efficiency. The content of organic matter in sheep manure is 24% – 27%, nitrogen content is 0.7% – 0.8%, phosphorus content is 0.45% – 0.6%, potassium content is 0.3% – 0.6%, organic matter content in sheep urine is 5%, nitrogen content is 1.3% – 1.4%, phosphorus content is low, potassium content is very rich, up to 2.1% – 2.3%.

1. Mix sheep dung with a proper amount of straw powder. The amount of mixing depends on the water content of sheep dung. Generally, 45% of the water content is required for fermentation. That is to say, knead it into a ball by hand, see water in the fingers, but do not drip, and release it to dissolve. Then add corn flour and bacteria. The role of corn flour is to increase sugar content for bacteria fermentation, so that multi-dimensional complex enzyme bacteria take advantage.
2. Add the prepared mixture into the mixer for mixing. The mixing must be uniform, transparent and free of raw blocks.
3. The mixed ingredients are stacked into strips with a width of 1.5 meters to 2 meters and a height of 0.8 meters to 1 meter, which are flipped once every 2 days with a tipping machine.
4. The compost is heated for 2 days, odorless for 4 days, loose for 7 days, fragrant for 9 days, and composted for 10 days (that is, the temperature on the second day of composting can reach 60℃- 80 ℃, killing diseases and insect pests such as Escherichia coli and insect eggs; the stink of sheep dung is eliminated on the fourth day; the compost becomes loose and dry on the seventh day, full of white hypha; a kind of liquor starter flavor is produced on the ninth day; the compost is fermented and matured on the tenth day).
5. After a little drying, it can be crushed by a semi-wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready for packaging and storage.

Organic fertilizer production line mainly crushes the previously fermented organic fertilizer raw materials, then sieved, and then measures the raw materials and other compatible components of the adhesive. After further drying to produce powder organic fertilizers), the materials that are fully mixed are evenly delivered to the granulator to make granules through the belt conveyor.

With the improvement of people’s living standards in China, people have higher and higher requirements for the quality of agricultural products and the environment of origin. Organic food, ecological food and green food will gradually occupy the high-end market. Therefore, an era of reducing the use of chemical fertilizers and pesticides and vigorously developing bio-organic fertilizers has come. At the same time, in order to ensure that enough organic matter returns to the soil, so as to promote the biological cycle in the land ecosystem on which we rely for survival, it has achieved the goal of maintaining and enhancing the long-term fertility and biological activity of the soil, accelerating the development of bio-organic fertilizer, and vigorously promoting the use of bio-organic fertilizer, which is of great significance to accelerate the development of China’s agricultural industry.

The production line of organic fertilizer equipment with an annual output of 10000 tons is composed of fermentation system, drying system, deodorization and dust removal system, special pulverizer for organic fertilizer, batching system, mixing system, special granulator for organic fertilizer and finished product packaging machine. Although the process structure is similar, the configured organic fertilizer equipment is not fixed. The construction and equipment purchase plan of the organic fertilizer production line with an annual output of 10000 tons is selected according to its own material characteristics, site operating conditions, specific production requirements, degree of automation and investment budget.

NPK fertilizer production line mainly crushes the previously fermented organic fertilizer raw materials, then sieved, and then measures the raw materials and other compatible components of the adhesive. After further drying to produce powder organic fertilizers), the materials that are fully mixed are evenly delivered to the granulator to make granules through the belt conveyor.

What equipment is required for the production line of chicken manure organic fertilizer with an annual output of 100000 tons?

Organic fertilizer equipment is a kind of equipment that uses chicken and pig manure as main raw materials, adds a certain amount of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances, and uses rice bran, yeast, soybean meal and sugar as biological bacteria for fermentation for a certain time to produce biological fertilizer by mixed fermentation under the action of high temperature. What equipment does the whole set of organic fertilizer equipment production line mainly include?

Raw material equipment for fermentation of organic fertilizer: There are many types of organic fertilizer fermentation equipment, such as trough tipping machine, wheel plate tipping machine, forklift fermentation tipping equipment, fermentation tank, etc., which are used for the fermentation treatment of livestock manure, and also used for biological fermentation of organic waste, straw and other raw materials to produce organic fertilizer. Among them, the forklift fermentation equipment can not only ferment the material, but also transport the material.

According to the process stage, the process of granular organic fertilizer production line is divided into ① crushing process; ② Fermentation process; ③ Mixing process; ④ Granulation process; ⑤ Drying process; ⑥ Screening process; ⑦ Coating process; ⑧ Packaging process. The process flow of powdered organic fertilizer includes the above ① crushing process; ② Fermentation process; ⑧ Packaging process.

Fecal composting organic fertilizer manufacturing process is to adjust the carbon-nitrogen ratio in the manure of the livestock and poultry by turning machine, manually controlling the conditions of water, temperature, pH and the like, and treating the manure of the livestock and poultry by the fermentation of the microorganisms to produce organic fertilizer.

I. Major organic fertilizer production equipmentfor composting

The composting process requires a large number of organic fertilizer processing equipment.

(1). Pre-treatment equipment: mainly include stockyard, unloading platform, feeding door, loading machinery, transport machinery and so on.

(2). Composting equipment: mainly trough compost turning machine, windrow turner machine, fermentation tank.

(3). Fertilizer granulator machine : mainly drum granulator, disc granulator, flat-die extrusion pelleting machine, organic fertilizer granulator, ring-die pelleting machine.

(4). Screening and packaging equipment: mainly drum screener, fertilizer packing machine.

II. Main Technical Parameters of composting

(1). C/N ratio: C/N balance of compost mixture is the key factor for microorganisms to achieve better biological activity. The C/N ratio of compost mixture should be kept at 25-35:1.

(2). Humidity: Aerobic composting should generally be maintained at 40-70%.

(3). Acidity and alkalinity: Acidity and alkalinity vary with the types of compost mixtures and different stages of composting process. Normally, they need not be regulated. If they need to be regulated, they can be regulated by adding alkaline or acidic substances to the mixture before the beginning of composting degradation.

(4). Other design parameters: Rectangular fermentation stacking composting mode, the windrow turner should be used regularly to turn the pile, so that the temperature is kept below 75℃, and the turning frequency is 2-10 days/time. The width and depth of rectangular stacks are limited only by the overturning equipment. The stacks are generally 1.2-1.8 meters deep and 1.8-3 meters wide. The height of the compost is usually 2.5-4.5 meters, and the width is usually twice the depth. Fermentation tank composting, need to build fermentation tank, fermentation tank length is unlimited.

III. Matters needing attention in composting

(1). Composting time: Composting time varies with C/N ratio, humidity, weather conditions, type of composting operation and management, waste and additives. The composting time of well-managed strip-cutting fermentation compost in summer is generally 14-30 days.

(2). Temperature: We should pay attention to the monitoring of composting temperature. The composting temperature should exceed 55℃, so as to be conducive to microbial fermentation and kill pathogens.

(3). Humidity: Pay attention to monitoring the humidity of compost mixture periodically. Excessive or low humidity will reduce or stop the composting speed.

(4). Odor: Odor is a good indicator of composting operation stage. Decay odor may mean that compost is changed from aerobic to anaerobic.
