fertilizer production line

With the rapid development of cattle farming, fecal pollution has become a major problem. According to relevant data, in some places, the pollution of cow manure to the environment has exceeded the total amount of industrial pollution, and some even reached more than twice. A cow produces over 7 tons of feces annually, while a yellow cow produces between 5-6 tons of feces. Due to insufficient attention paid to the treatment of cow manure in various regions, there are basically no cow manure treatment facilities in some areas where cattle farming is concentrated. This leads to cow manure being piled up and scattered everywhere, especially in the south. Every summer, the odor rises to the sky, causing adverse effects on the normal life of surrounding residents. At the same time, cow manure is also the source of breeding and breeding of various bacterial pathogens, which has a serious impact on the breeding population. In addition, when cow manure is used on the ground, it generates heat, consumes soil oxygen, causes root burning and seedling burning, and also plays a role in spreading parasitic eggs and pathogenic microorganisms. Therefore, cow manure treatment is very important.

Price analysis of Organic fertilizer equipment manufacturers on cow dung Manure complete equipment

When it comes to the price of cow dung Manure complete sets of equipment, this is a problem that most users are concerned about. The lower the purchase cost of cow dung Manure complete equipment is, the higher the future income will be. However, we should also pay attention to quality issues. Therefore, the cost performance ratio should be comprehensively considered. Compared with other crushers with the same output, the price of cow dung Manure complete equipment is economical. In terms of the whole industry, the price of cow dung Organic fertilizer complete equipment is generally related to the manufacturer, quality, sales mode and other aspects.

1. Manure Organic fertilizer complete equipment manufacturer

Generally speaking, the prices of cow dung Organic fertilizer complete sets of equipment given by different manufacturers are different, because the production strength, processing technology, production process, raw material selection, etc. of different manufacturers are different, so the equipment prices given will also be different.

3. Sales mode of cow dung Organic fertilizer complete equipment

There are many businesses selling complete sets of equipment for cow dung Organic fertilizer on the market. Generally, the price of the former is lower than that of the manufacturer’s direct selling equipment, because the manufacturer’s direct selling equipment is designed, developed, manufactured and sold by itself, and it is a direct ex factory price, so the price is lower. And the price of equipment sold by intermediaries will be slightly higher, because not only does the intermediate circulation link increase, but intermediaries also have a certain profit margin to make money, so the equipment price will also be higher.

The development of NPK manufacturing process equipment can not be separated from the promotion of science and technology. Under the role of market economy, if you want to develop, you must carry out scientific and technological reform, so that you can be a foothold in the market competition and become the industry leader.

The equipment has quick effect and good economic benefits, and the complete set of equipment has compact flow layout. It reduces the energy consumption of the equipment, makes the operation of the equipment stable, has no discharge of three wastes, and is convenient for maintenance. Wide adaptability of raw materials, suitable for granulation of compound fertilizer, feed and other raw materials, with high product granulation rate. It can produce compound fertilizers of various concentrations and types (including). Especially the granulation of rare earth and ammonium bicarbonate series compound fertilizers.

Process flow of 15-20 t/d Organic fertilizer production line:

1. The production process of Organic fertilizer granulator is mainly to screen, magnetic separation, granulation and drying the organic waste with a moisture content of about 30% -35% after fermentation and decomposition to prepare round Organic fertilizer. Adding functional bacteria can produce biological Manure, and adding nitrogen, phosphorus and potassium (the total nutrient content is less than 15%) can produce organic and inorganic fertilizer.

2. After magnetic separation and screening of the fermented organic waste, it is measured and batched with the raw materials of binders and other components that need to be compatible according to the ratio requirements. It is lifted by a bucket elevator to a multi-dimensional high-efficiency mixer for rapid mixing. The fully mixed material slides out into the mixing silo, and is uniformly and continuously fed into the extrusion granulator by a disc feeder to form columnar particles;

3. The particles are polished and shaped into spherical particles by the round particle polishing and shaping machine, and sent to the drying, cooling, Organic fertilizer screening machine (three in one model) by the belt conveyor. The particles are dried at low temperature and large air volume in the front section of the drying and cooling screening machine (≤ 65 ℃), and then enter the cooling section for air cooling. The fully cooled materials enter the screen installed at the end of the cylinder, and the screened finished particles are transported to the finished product silo by the elevator, and then measured by the packaging system Packaging and warehousing;

4. The screened large particles are crushed and then returned to the mixed granulation system; The small particles screened out (basically without powder) can be made into small packaging and sold directly.

Process characteristics of 15-20 t/d Organic fertilizer production line

（1） The new process of extrusion granulation and polishing can be used to produce “spherical” pure Manure, organic and inorganic fertilizer, and biological Manure. The process flow is short, the operation cost is low, the Manure produced is uniform and round, the surface is smooth, the compressive strength is high, the fluidity is good, the survival rate of microbial bacteria is>90%, the granulation rate is 85-95%, and the particle diameter is 3.5-4 mm.

（2） The new process of extrusion granulation and polishing and shaping has strong adaptability to raw materials, which can completely solve key technical problems that traditional granulation processes such as discs or drums are difficult to solve:

1. The fermented organic materials can be directly used for granulation without the need for pre drying or crushing treatment. Traditional granulation processes such as disc or drum have high requirements for raw material fineness, which means that over 80% of the material should have a fineness of over 80 mesh. Therefore, it is necessary to crush it. Due to the high moisture content of the fermented organic material, it needs to be dried to below 13% moisture before crushing to meet the crushing conditions, which requires high equipment investment and high operating costs.

2. It can increase the addition amount of organic materials to over 95%. Traditional granulation processes such as disc or rotary drum use more than 80 mesh organic materials and add binders, and the maximum amount of organic raw materials is 30-40%. Therefore, to produce spherical Organic fertilizer with high content or pure organic matter, traditional granulation processes cannot be achieved.

How much is the manufacturer’s quotation for a full set of 3000-5000t/a Organic fertilizer production line? There is no complete answer to this question, because different equipment configuration schemes, different production line process designs, and different output demands of Manure production lines with an annual output of 3000-5000 tons will require different funds. The specific quotation of Organic fertilizer production lines with an annual output of 3000-5000 tons depends on the actual configuration. However, it can be determined that the configuration is more scientific, more reasonable and more suitable for actual production, and the price investment of equipment will be more cost-effective. Generally, the manufacturer’s quotation for a full set of Organic fertilizer production lines with an annual output of 3000-5000 tons will be in the range of 80000-50000.

Drying equipment is an important equipment in the production line of granular Organic fertilizer materials, mainly drying Organic fertilizer granules. The Organic fertilizer dryer can directly dry materials with moisture content up to 70% -80% to 13% of safe stored moisture at one time. The whole process is carried out in a Closed system, thus reducing environmental pollution in the drying process.

Organic fertilizer dryer equipment: mainly composed of heat source, feeder, feeder, rotary drum, discharge machine, material crushing device, induced draft fan, discharger and power distribution cabinet.

Working principle of Organic fertilizer dryer:

After the dehydrated wet materials are added into the Organic fertilizer dryer, the materials are evenly dispersed in the dryer and fully contacted with the hot air when the uniformly distributed plate reader in the drum is turned, which speeds up the drying heat and mass transfer. During the drying process, the material is discharged from another section of the star discharge valve of the dryer under the action of the inclined plate and the hot air.

How to arrange Organic fertilizer dryer in Organic fertilizer production line?

1. Feeding silo: To prevent wet and sticky materials from clogging in the feeding silo, a reasonable feeding silo structure should be designed, such as using an asymmetric geometric shape hopper; Or increase the inclination angle of the bucket wall and the discharge port; Adding activation cones or pressure reducing plates in the silo; Alternatively, set up material piercing holes at the exit. At the same time, it can also reduce the amount of material in the silo, reduce the pressure of the silo, and prevent material blockage. It can also design a vibration feeding hopper for arch breaking and unloading according to the properties of the material, which is used for feeding the dryer.

2. Combustion chamber: The appropriate combustion chamber should be selected based on the nature, source, dryer type, and other factors of the fuel, combined with the factory conditions. For example, if the factory has coal powder, it can be considered to use a coal powder combustion chamber; Low quality coal can be used in fluidized bed furnaces, etc.

Secondly, the combustion chamber of the dryer equipment generally needs to consider setting up a “air flue gas” mixing chamber, installing a thermometer to measure the flue gas temperature, and a cold air door to adjust the amount of cold air added. We also need to design a reasonable wind barrier to prevent high-temperature flames from burning towards the dryer cylinder and feeding pipe. The feeding pipe is coated with heat-resistant concrete or brick chutes. In addition, reducing the amount of cold air leakage into the feeding pipe is beneficial for improving drying efficiency.

3. Drying heat system: The drying heat system includes three parts: combustion chamber, dryer, and exhaust dust collection. The selection of exhaust fan and dust collector should meet the combustion air coefficient of not more than 1 and 2 when entering the dryer; The working wind speed at the cold end of the dryer should not exceed 3m/s; The discharge port under the suction hood should be equipped with a locking device; Dust collectors and exhaust ducts need to have insulation and insulation measures.

The development of green agriculture and agricultural circular economy has been gradually carried out to alleviate the problems of environmental pollution and soil degradation. In order to develop ecological agriculture and promote agricultural cycle, environmental pollution caused by chemical fertilizer should be solved first. We turn our attention to the application of organic fertilizer. In recent years, the use of organic fertilizer in China has been increasing year by year, especially in fruits, vegetables, tea and horticultural products. In addition, we have vigorously promoted the substitution of organic fertilizer for chemical fertilizer, and promoted green prevention and control and biological control. Organic fertilizer production equipment improves the local ecological environment and forms agricultural ecological cycle.

For organic fermentation fertilizer and organic fertilizer raw materials, such as livestock manure, manure, compost, green manure, sea manure, cake fertilizer, peat, soil manure, three wastes, microorganisms and other organic wastes. The qualified rate of granulation of new organic fertilizer granulator is as high as 80-90%, which is suitable for a variety of different formulations. The pelletizer has high pelletizing rate, and the large ball rate is less than 15%. The particle size uniformity can be adjusted by the stepless speed regulation function of the machine according to the user’s requirements. This machine is more suitable for direct granulation after organic fertilizer fermentation, saving drying process and greatly reducing production cost.

The thickened, weighted and solid base design, It is an ideal equipment for granulating organic fertilizer and compound fertilizer without fixing with anchor bolts and running smoothly.

The NPK compound fertilizer production line roller extrusion granulator uses dry extrusion technology to compress powdery materials with a moisture content of less than 20% into flakes, and then undergoes crushing, granulation, and screening processes to turn the block shaped materials into granular materials that meet the usage requirements. Dry rolling granulation mainly relies on external pressure to force the material to pass through the gap between two relatively rotating rollers and compress into pieces. During the rolling process, the actual density of the material can increase by 1.5 to 3 times, thereby achieving a certain strength requirement.

What are the granulation shapes of the roller extrusion granulator on the NPK compound fertilizer production line?

The particle size of the finished product can be adjusted in a large range by changing the sieve plate aperture of the crushing and pelletizing machine. The roller skin can be customized according to the customer’s requirements to extrude particles of different shapes, such as spherical, capsule shaped, Corn kernel shaped, rod shaped, etc. Also, patterns and anti-counterfeiting marks can be carved according to the customer’s requirements. The size of the roller skin ball socket determines the size of the material diameter, which is generally 3-8mm.

More and more people are joining the Manure production camp, and the breeding plants are building new Organic fertilizer plants, Not only has it solved the pollution and safety issues of aquaculture plants, greatly improved the living and working environment of practitioners, but it has also become a new economic growth point for aquaculture plants.

Granulation process of small Organic fertilizer production line

1: Fermentation

Collect cow manure and auxiliary materials, mix them with organic materials such as hay straw and livestock manure to make compost and let it ferment. During the fermentation process, a tipping machine is used to fully ferment the material. Only timely and uniform tipping can achieve this. Now some places are very dry and some places are very wet, which will affect the fermentation quality. It is recommended to use Organic fertilizer dumper.

2: Ingredients crushing and mixing

Using a batching bin, the composted materials, inorganic fertilizers such as N, P, K, and other additives are crushed, proportioned, and mixed in a certain proportion through a material crusher and a horizontal mixer. The function of this system is to crush, mix, and mix the composted materials with various raw materials such as nitrogen, phosphorus, potassium inorganic fertilizers, and other additives in a certain proportion. Based on years of experience, the equipment supporting suggestions are as follows: vertical Organic fertilizer grinder is used to crush cow manure compost, which is not easy to stick to the wall and block, and multi-layer turbulent chain hammer structure improves the crushing performance; The continuous automatic batching system is suitable for the dynamic metering and batching control of Manure raw materials; The mixing operation is equipped with a dual axis continuous mixer, which has good sealing performance and prevents sticky and wet materials from adhering to the root of the mixing shaft.

3: Granulation

A new type of Organic fertilizer granulator is used to granulate materials. The function of this system is to mix the crushed ingredients into particles. The granulation process is suitable for using a disc granulator, a toothed granulator, or a new type of toothed rotating strand combination granulator. Its advantages are: wide adaptability of raw materials, especially suitable for organic materials, wide requirements for raw material density and moisture content, stable granulation, high particle forming rate, and uniform appearance of finished particles that are not easily broken;

4: Drying

Use Organic fertilizer dryer to further remove water from granulated particles to meet the standard requirements of Manure moisture content.

5: Cooling
