The self-propelled composter is a Manure fermentation equipment developed based on dynamic composting. The earliest composting process is static composting, which is often converted into anaerobic fermentation due to insufficient oxygen supply, which will produce a large amount of hydrogen sulfide and other odor, and there is an explosion risk. Later, our company developed a new generation of Manure fermentation equipment, self-propelled fermentation composter, which can make full use of space, and the whole machine is solid; The vehicle body is flexible and can easily and conveniently lift the drum as a whole; Adopting advanced engineering machinery transmission technology to ensure no loss between energy conversions; Each component is connected to each other and can be adjusted separately; Under normal operation and attention to maintenance, using the machine is zero fault; Fully ferment the raw materials to quickly achieve the effect of no odor, no harmful bacteria such as Escherichia coli.

The self-propelled composting machine/self-propelled tipping machine has obvious advantages such as low investment, low energy consumption, fast composting, and high yield. The self-propelled Manure composter is an ideal equipment to use modern technology to transform agricultural wastes, stored feces and organic household garbage into high-quality biological Manure. Main features: It saves a lot of civil engineering and manpower and material engineering, making the scalability of fertilizer production more arbitrary and not limited by the site, allowing for multiple uses of one machine.

The self-propelled composter is the main machine of the complete set of equipment dedicated to the production of Manure. It adopts a four-wheel walking design, and can move forward, backward, and turn. It is operated by one person. When driving, the whole vehicle rides on the pre stacked strip Manure pile, and the rotating knife hung under the machine is used to remix, fluff, and move the raw materials of the fertilizer machine. After the vehicle passes, a new strip stack is formed, which can be operated either in the open field or in the workshop shed. A major technological breakthrough of this machine lies in the integration of the crushing function in the later stage of material fermentation. As the material gradually dehydrates, the knife equipped with a crushing device can effectively crush the plates formed during the fermentation process of the fertilizer. Not only does it save a crusher, but it also greatly improves the efficiency of crushing, reduces costs, and fundamentally solves the problem of limited production capacity of the crusher. Composting machines have significant effects compared to other types such as “tipping machines”, “mixers”, and “spiral stirring machines”. So one machine can be used for many purposes. It is not only a Manure dumper, but also a Manure grinder.

The cattle manure fertilizer production process, only 7 steps, makes the manure become organic fertilizer, and makes the cow manure greatly profitable.

1. Fermentation stage of cattle manure fertilizer production process:
Collect cow dung and urine, add auxiliary materials to make compost, and let it ferment. In the fermentation of seed, we use a dumper to fully ferment the cow dung, which can only be done in a timely and even way.
2. The composted materials, such as N, P, K and other inorganic fertilizers, and other additives are crushed, proportioned and mixed through the material crusher and horizontal mixer according to the proportion.
3. Granulation stage of cattle manure fertilizer production process:
A new type of organic fertilizer granulator is used to granulate materials.
4. Screening and recycling system of cattle manure fertilizer production process:
The size of the particles output from the pelletizing and forming system is different, so it needs to be screened and graded. The selected rotary screen machine requires small vibration, low noise, convenient screen changing and equipped with screen surface cleaning device.
5. Drying stage of cattle manure fertilizer production process:
Using the organic fertilizer dryer, the sieved particles can be further removed from the water to meet the standard requirements of the moisture content of organic fertilizer.
6. Cooling stage of cattle manure fertilizer production process:
Cooling the granular materials with a cooler is helpful for the storage and quality of the granules.
7. Packaging stage of cattle manure fertilizer production process:
The cooled granular materials are transported into the finished product warehouse by the bucket elevator. The granular materials can be weighed and packed quantitatively by automatic packing scale.
In the whole production process, the fermentation equipment of organic fertilizer is very important, and the quality of organic fertilizer also depends on the fermentation process. Therefore, the fermentation process of organic fertilizer is paid attention to by everyone. In the process of organic fertilizer fermentation, the heating time of organic fertilizer equipment refers to the early stage of the composting process. The temperature rise of compost gradually increased from room temperature to 45 ℃. The main microorganisms are thermophilic microorganisms, including bacteria, fungi and actinomycetes. The differentiation matrix was mainly carbohydrate and starch. The fruiting bodies of fungi can be found in time, and animals and protozoa participate in differentiation.

With the large demand for organic fertilizer, many manufacturers will provide better business opportunities. Many types of organic fertilizer production line manufacturers emerge layer by layer. There are direct sales type and agent type manufacturers. The prices of organic fertilizer production lines given are very different. If you want to buy organic fertilizer production lines with affordable prices, it is more important to select the manufacturers.

The investment price of organic fertilizer production equipment can be more or less, if the production of powdered organic fertilizer processing, only need to invest in a fermentation equipment, grinder, screening machine. Investment is more than 60000 yuan.
If the granular organic fertilizer is produced, the fertilizer granulator machine and dryer of organic fertilizer need to be added, and the annual output of organic fertilizer is 10000 tons. Generally, cooling machine is not needed. The investment is about 200000 yuan. The construction site can be large or small, and the general site needs 3 to 5 mu of land.
The production process of the more complex chicken manure organic fertilizer production line is as follows: after fermentation, the raw materials of organic fertilizer (animal manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.) enter the semi wet material crusher for crushing, and then add nitrogen, phosphorus, potassium and other elements to make the mineral elements meet the required standards. Then, there is a mixer to stir them, and then they enter the granulation mechanism for granules. After coming out, they are dried and screened by a screening machine, Qualified products shall be packaged, and unqualified products shall be returned to the granulator for granulation.

Technological process of Organic fertilizer production line with an hourly output of 5-6 tons:

1、 Directly enter the recycled livestock and poultry manure into the fermentation zone. After one fermentation and two aging stacking, the odor of livestock manure is eliminated. At this stage, fermentation strains can be added to decompose the coarse fibers in order to meet the particle size requirements of granulation production after crushing.

2、 Crush the fermentation materials that have completed the secondary aging stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add N, P, K, and other trace elements to the mixing and stirring system to start stirring.

3、 The mixed materials will be delivered to the Organic fertilizer granulator, and the granulated materials will enter the cooling system after being dried. The materials will be screened after reaching the normal temperature. The qualified particles will enter the coating machine to wrap the film and then start packaging. The unqualified particles will be crushed by the Organic fertilizer grinder and returned to the granulation system again to continue granulation.

4、 Automatic packaging of finished products.

Composting and fermentation of fertilizer production process is a process to realize the harmless of organic materials. There are two types of commonly used processes, i.e. stacking process and tank process.
1. Strip and stack fermentation
Stacking composting process is a common aerobic fermentation system, which can decompose raw materials in aerobic condition by stacking them in long strips or stacking.
① Heap shape. The bottom width of the pile is controlled between 120-300cm (or determined according to the width of the crawler compost windrow turner), and the pile height is controlled between 80-200cm, with 120cm as the most appropriate; the length is unlimited. The spacing of each stack is about 80-100cm;
② Composting equipment. It is mainly a stacker tripper: the technical parameters of the main equipment are the maximum allowable stacker height of 200cm, stacker width of 300cm, forward / backward speed of 5-15m / min, and production capacity of not less than 600m3 / h.

2. Trough fermentation
Tank fermentation is a kind of aerobic composting fermentation technology, which combines controlled ventilation and regular turning of piles.
① The size of fermentation tank is usually L × w × H = (60 ~ 100) m × (4 ~ 9) m × (1.5 ~ 2) M. guide rails are laid on the upper part of the tank wall for the convenience of the composter walking; aeration system is laid on the bottom of the tank to ventilate and oxygenate the fermentation materials in the tank, which is mainly composed of high-pressure fans and ventilation pipes.
② The tank type compost turning machine agitates the materials evenly by mechanical agitation, promotes the heat and moisture volatilization, and displaces the materials slowly in the tank. Common organic fertilizer machines include chain plate and agitator, mainly composed of traveling chassis, chain plate (agitator), hydraulic lifting part, transmission part and electric control part. 
Tank type organic fertilizer fermentation equipment. The equipment required for tank fermentation is the tank fermentation dumper, which has the advantages of large processing capacity, small land occupation, simple operation, driverless and so on. However, due to the construction of fermentation tank, the fermentation field is fixed, which has certain limitations, and the air permeability is not as good as the strip stack type. At present, based on the function of turning and throwing, some trough fermentation organic fertilizer dumpers are designed with oxygenation devices to increase air permeability; Some add the function of crushing and stirring, which is suitable for fecal type, dregs and fermented products with more fiber and less viscosity. In this way, the pretreatment processes of raw material stirring and crushing can be saved and the production links can be reduced. The trough organic fertilizer dumper is mostly driven by motor because it walks on a fixed track, and its price is mainly related to its motor power.

Cow manure is a large amount of feces excreted by cows during the process of raising cattle, which is a coarse fibrous substance mixed with a large amount of urine and mucus. Cow manure is a type of livestock manure that is not easy to air dry. With the continuous expansion of aquaculture scale in China, intensive farming has brought about the concentration of a large amount of cow manure, which is difficult to handle when piled together. Cattle farms use cow dung Manure equipment production lines to process cow dung Manure, which has benefited many enterprises. The input-output ratio is a topic of concern for the project party of cow dung Organic fertilizer equipment processing.

The quality of cow dung Organic fertilizer equipment and the price of equipment have attracted the attention of fertilizer processing plants and farmers. How much can I buy a set of cow dung Organic fertilizer equipment today? Which is the best manufacturer of cow manure treatment equipment in cattle farms?

Generally speaking, cow dung Manure is not expensive, and the equipment needed for cow dung Manure is customized and purchased according to the specific conditions of the manufacturer. Generally, the equipment needed includes fermentation dumper equipment/dumper equipment, granulation equipment, mixing equipment, crushing equipment, drying equipment, screening and grading equipment, packaging equipment, transportation equipment, dust removal equipment, etc.

Analysis of the price and equipment needed for cow dung Organic fertilizer equipment

Processing cow dung Manure from cattle farm waste is a good project for the country, the people and the enterprise. On the one hand, it meets the requirements of the current national demand for agricultural environmental protection, and also conforms to the current policy trend of “comprehensive recycling of resources”. At the same time, because the cow dung Manure equipment can increase the income of farmers. It is highly popular among large cattle farmers. The price of the entire set of equipment is determined by the equipment and model required by the designed process. The specific details are roughly as follows:

1. The overall equipment of the small powder cow dung Organic fertilizer production line is low in price and small in investment. Required equipment Common small Organic fertilizer equipment: Organic fertilizer high moisture material grinder, Organic fertilizer drum screening machine, 2M/3M fermentation dumper or Organic fertilizer composter, small conveyor, the other is packaging machine equipment. The purchase of such a set of cow dung Organic fertilizer equipment is about 50000 yuan.

2. In addition to the basic equipment required in powdered cow manure, the equipment required for the production line of small granular cow manure Organic fertilizer also needs to be added with Organic fertilizer granulator equipment, Organic fertilizer drum dryer equipment, Organic fertilizer cooler equipment, coating machine, packaging machine equipment, etc. Such a production line of small granular cow manure Organic fertilizer depends on the granulation system, but its price is basically between 100000 yuan and 500000 yuan.

3. Equipment for medium-sized and large-scale cattle manure Organic fertilizer production line. In this case, it is mostly used for professional Manure manufacturers. The characteristic is that the output is large, and the degree of automation is significantly improved compared to small ones, resulting in an overall improvement in equipment performance. And the required equipment is basically similar to 1. and 2. It is only a change in equipment capacity and automation level. However,

Large and medium-sized cattle manure Organic fertilizer production line equipment still has a great impact on the price. The price of the whole set of medium-sized Organic fertilizer equipment: 300000 yuan -2 million yuan. The price of the whole set of large-scale Organic fertilizer equipment is basically above 800000 yuan.

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.

2. Quality of complete equipment for cow dung Organic fertilizer

The quality of complete equipment for cow dung Organic fertilizer varies from high to low. High quality equipment, with high technical content and exquisite workmanship, is processed from high-quality steel with good wear resistance. It is also relatively stable and reliable in actual operation, with large processing capacity, high output and good economic benefits. Therefore, the price is relatively high.

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. NPK manufacturing process equipment has achieved the present achievements, to a large extent, is under the guidance of science and technology development, become now well-known production equipment, it can be said that science and technology has made the compound fertilizer production equipment today.

The application of science and technology in NPK manufacturing process equipment makes us bid farewell to the previous low efficiency and high cost production mode, and enters the stage of rapid development. Science and technology is becoming more and more powerful, and the equipment is becoming more and more perfect. Relying on the power of science and technology, it overcomes the problems of the equipment itself in the technical level, and makes it develop better. In addition, with the efforts of the equipment manufacturing enterprises themselves, we can let go He can better serve enterprises and consumers.
It can be said that the achievements of NPK manufacturing process and equipment today are inseparable from the technical development of various industries. Excellent equipment quality can win the good reputation of users. Only the word-of-mouth of users can move people’s hearts. Therefore, we should also develop towards more efficient, convenient operation, automation and multi-function, and steadily develop in the fierce competition in the future, We should do solid work in technology and make progress in stability. 
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.
