The pellet produced by disc fertilizer granulator machine is suitable for machine sowing, and the output is relatively high. The kneaded material is rolled into a round ball with no return material, high efficiency and good strength. Beautiful appearance, reasonable structure, safe and reliable, easy to operate.
Disc fertilizer granulator machine has a strong ability to prevent overload, even in the case of full load, there is no need to set up a separate feeding device.

The characteristics of disc bio organic fertilizer production technology are as follows:
1. It can directly produce spherical particles in one step, no size and no material return, and the rate of ball forming is more than 95%. Therefore, the production cost is low and it is suitable for machine seeding.
When the moisture content of raw material is about 40%, the drying and post-treatment are easy and the drying cost is low. Because it can be dried at low temperature or in the air, it will not affect the number of bacteria in the biological fertilizer.
3. Wet granulation has the advantages of low wear and low cost.
4. It has wide adaptability to all kinds of materials used in organic fertilizer granulation. 

There are two main types of organic fertilizers processed by organic fertilizer production equipment: powdered fertilizers and granular fertilizers. Granular fertilizers are more commonly used in daily processing. The main purpose of using organic fertilizer production equipment to produce granular organic fertilizers is to facilitate bagging and transportation to prevent secondary fermentation of organic fertilizers. In addition, in terms of sales level, granular organic fertilizers are better sold.

According to primary and secondary
(1) Main raw materials. The main raw material of organic fertilizer production process accounts for 30% – 80% of the whole material, which is composed of one or several raw materials. The main materials commonly used are animal manure, straw powder, mushroom residue and so on.
(2) Accessories. It is mainly used to adjust moisture, carbon nitrogen ratio, pH value and permeability of some raw materials, composed of one or several raw materials. Usually, this kind of raw material accounts for less than 40% of the whole material, and the proportion of single material is less than 20%. The commonly used auxiliary materials are wheat bran, soybean meal, peat, plant ash, quicklime, etc.
Classification by raw material properties
According to the properties of raw materials, it can be divided into carbon containing raw materials, nitrogen containing raw materials and conditioner raw materials.
(1) Carbonaceous materials. It refers to the raw materials with high organic carbon content, which are usually used as main composting materials, such as straw, rice husk, mushroom residue, etc. In addition to straw composting, most of the carbonaceous materials are used as auxiliary materials to adjust water content, carbon nitrogen ratio, bulk density and enhance the permeability of materials.
(2) Nitrogen containing raw materials. Generally refers to the raw materials with carbon nitrogen ratio below 30:1, such as livestock manure. There are also some high nitrogen raw materials used as auxiliary materials to adjust the carbon nitrogen ratio, such as soybean meal, fish meal, etc.
(3) Conditioner raw materials. It mainly refers to raw materials used to adjust pH value, such as quicklime to adjust acidity and gypsum to adjust alkalinity. Sometimes the raw materials used to adjust the C / N ratio are summarized as regulators, such as superphosphate, phosphate rock powder, etc. 

Small organic fertilizer equipment worth around 11000 yuan is highly welcomed by ordinary farmers. There are many raw materials for organic fertilizer, such as livestock and poultry manure, agricultural waste, plant ash, mushroom residue, etc. The majority of livestock and poultry manure is treated, many of which are owned by farmers. Small organic fertilizer production lines can meet this requirement, not only solving the problem of emission reduction and disposal of livestock and poultry manure, but also making money from livestock and poultry manure, bringing significant profits.

Organic fertilizer production lines are generally divided into two categories: powder organic fertilizer production lines and granular organic fertilizer production lines, taking powder organic fertilizer production lines as an example. The equipment required includes fermentation and tipping equipment, pulverizer equipment, and organic fertilizer screening equipment. The price is around tens of thousands of yuan, which needs to be determined based on annual production and equipment specifications.

1. Determine the scale of the small-scale organic fertilizer equipment production line, such as how many tons per year or how many tons per hour, before determining the price.

2. Determine the shape of particles in the production line of small organic fertilizer equipment, that is, choose what type of granulator: powder, column, flat ball, or standard park. Commonly used organic fertilizer granulator equipment includes: disc granulator, drum granulator, wet granulator, drum extrusion granulator, flat mold granulator, and stirring tooth granulator. The selection of granulators should be determined based on the local organic fertilizer sales market. If the shape requirements of the particles are different, then the processing process of organic fertilizer equipment is also different, and the price of organic fertilizer equipment is also different.

3. Determine the configuration of small organic fertilizer equipment production lines: The equipment configuration of organic fertilizer production lines varies, with varying prices and labor intensity. If the output is stable and high, the general configuration is relatively high. In addition to the basic equipment, automatic batching equipment, automatic packaging equipment, automatic quantitative feeding equipment, cyclone dust collector, solid-liquid separation equipment, etc. should also be added.

4. Determine the type of organic fertilizer production. Compound organic fertilizer equipment or organic fertilizer equipment, with the same yield, generally considers high moisture content, beneficial bacteria not resistant to high temperature, and the model is larger than the compound fertilizer model. There are four types of organic fertilizers: pure organic fertilizer, organic-inorganic composite fertilizer, bio organic fertilizer, and composite microbial fertilizer, with slightly different configurations of organic fertilizers.

5. Selection of organic fertilizer fermentation tipping machine: Common organic fertilizer fermentation methods include strip fermentation, tank fermentation, and the use of fermentation tanks. The fermentation methods and equipment for organic fertilizer fermentation are also different. In general, the tank fermentation tipping machine is more suitable for the principle of aerobic fermentation (advantages of tank fermentation: it is more in line with the principle of aerobic fermentation, less prone to the formation of anaerobic bacteria, complete fermentation, and fast fermentation speed).

6. Determine the environmental assessment to be achieved: select ordinary dust removal equipment in areas with low environmental assessment requirements, and invest less in organic fertilizer equipment; Areas with high environmental protection requirements require the use of high-performance dust removal equipment, which has good performance and can fully meet national environmental standards. Therefore, the investment will also be higher.

The non drying extrusion granulation process of double roller granulator has a wide range of applications in powder processing. Its characteristic is that it can process particles directly without humidifying or heating materials. It can be used for the processing of organic and inorganic fertilizer granules and feed granules.

No waste water or waste gas will be discharged in the production process by using the non drying extrusion granulation process, and the environment will not be polluted. Extrusion double roller granulation process is short, easy to operate, easy to realize production automation control and improve production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are wide.

Five stages of the production process of organic fertilizer by double roller granulation
1. Add the qualified raw materials into the fertilizer mixer machine according to the proportion requirements and mix them evenly.
2. It is transported to the disc feeder, and the metallic substances in the material are removed during the conveying process.
3. The material in the disc feeder evenly enters into the double roller granulator, and the material is forced to pass between the two pressure rollers to be squeezed into thin plates. The thin plates are crushed into fragments by the coarse crusher under the pressure roller and then screened. The materials on the screen continue to be broken and sieved.
4. The semi-finished products are transported to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the pulverizer and then returned to the disc feeder.
5. After screening, the qualified products are transported to the automatic packaging scale for weighing, packaging and warehousing. 

With the increasing attention of governments at all levels and the recognition of organic fertilizer by farmers, the production and market of organic fertilizer have entered a period of rapid development. In the process of organic fertilizer production by organic fertilizer machine, feed production equipment or general compound fertilizer production equipment is commonly used, but it is often not suitable for selection due to poor pertinence.

1: The results showed that the crawler type compost windrow turner should be used in the strip stack fermentation. This type of composting method has the advantages of flexibility, simplicity, large treatment capacity and good air permeability. When processing the same volume of organic materials, the area occupied by strip stack fermentation is 2-3 times of that of trough fermentation.

2: Trough fermentation: trough fermentation is generally a partition wall built on the cement floor, and the top of the partition wall is paved with guide rails. The compost windrow turner walks on the guide rail and is equipped with a rail changing mechanism. The tipper can move from one trough to another. Whether it is a self-propelled compost windrow turner or a trough tipper with multiple troughs or one trough with one machine, the operation of the tipper will be more flexible if it has the function of breaking and stirring during the turning process.

3: The main equipment of trough fermentation is chain plate compost windrow turner; the chain plate compost windrow turner can be equipped with bacterial liquid spraying device, which can well meet the process requirements and spray mixed bacterial liquid according to the working characteristics of the compost windrow turner, so as to reduce the mixing process in the early stage. 

Cow manure is a very good organic fertilizer raw material, and investing in cow manure organic fertilizer processing plants in rural areas is a good project Cow and sheep manure is very cheap in resource-rich areas, and in some places, it is even free because farms mainly focus on farming as a profit point. They do not have the energy to handle this manure, but instead become their problem. Therefore, the price of raw materials is generally within 100 yuan per ton. The cost of processing organic fertilizer is around 150 yuan per ton, including equipment wear and tear, artificial water and electricity, etc. The market price ranges from 400-800 yuan, so the profit per ton is at least 150 yuan. If 3000 tons can be sold in a year, the annual profit will be about 450000 yuan.

Sheep manure organic fertilizer production equipment:

What are the equipment for producing sheep manure organic fertilizer? There are roughly two options for production equipment. One is to purchase a complete set of sheep manure organic fertilizer equipment, with about 10 types of equipment. The complete set of equipment can establish a large-scale production workshop for long-term and large-scale organic fertilizer production. The advantage of a complete set of organic fertilizer equipment is its high automation ability, higher quality organic fertilizer produced, and thus higher sales prices. Secondly, there are not many existing organic fertilizer raw materials that pollute the environment and are sold to others at a low price. At this time, one or two small organic fertilizer equipment can be purchased specifically for simple processing, which can be sold to surrounding farmers. This not only timely handles fecal pollution, but also brings profits.

Common organic fertilizer equipment:

Fermentation flipping machine is used for the fermentation flipping of organic fertilizer raw materials, with the aim of allowing the raw materials to ripen more quickly and evenly.

Organic fertilizer crusher is used for the crushing process of powdered organic fertilizer, making the particles of powdered organic fertilizer more uniform and of better quality.

There are many options for producing organic fertilizers besides sheep manure, such as pig manure, cow manure, chicken manure, straw, etc. However, the most important thing is to look at the abundant raw material resources around, after all, these raw materials are not very convenient in transportation, and the selection of raw materials should still be based on the principle of proximity.

In the granulation process of fertilizer production line, silicon fertilizer, boron fertilizer and other beneficial elements and trace elements can be added on the basis of nitrogen, phosphorus and potassium fertilizer to make the nutrients more comprehensive.

Function of silicon fertilizer in agriculture

1. Silicon is an important nutrient element for plant body composition, and is listed as the fourth largest element after nitrogen, phosphorus and potassium by the international soil community. Therefore, in industrial processing, silicon fertilizer is added to nitrogen, phosphorus and potassium fertilizer, and compound fertilizer is made with the disc granulator.

2. Silicon fertilizer is beneficial to increase the photosynthesis and chlorophyll content of crops, make the stems and leaves straight, and promote the accumulation of organic matter.

3. Silicon fertilizer can increase the mechanical strength of crop stem, increase the lodging resistance by more than 85%, and make the stem straight, which is conducive to close planting.

4. Silicon fertilizer can improve the resistance of crops to diseases and insect pests, reduce the occurrence of various diseases and insect pests. After absorbing silicon, silicon cells can be formed in plants, which thickens the cell wall of the surface layer of stem and leaf, increase the cuticle layer, and form a solid protective layer, which makes insects not easy to bite and bacteria to invade. In particular, the resistance to rice blast, stem rot, seedling rot, leaf spot, Fusarium wilt, root rot, borers, aphids, cotton bollworm, root nematode and other diseases and insect pests were strengthened.

5. Silicon fertilizer can enhance the aeration of crop, prevent root rot and premature senescence, and play an important role in the control of rice root rot. NPK fertilizer granulator is suitable for compound fertilizer granulation. Silicon fertilizer is used as a raw material for further processing.

Organic fertilizer crawler compost windrow turner is a kind of large-scale compost machine. It is full hydraulic operation system, pull rod type steering wheel operation, crawler type walking, strong power, advanced technology, large output, strong overturning capacity, hydraulic lifting adjustment of tipping drum, high automation, simple operation, it is the compost equipment for organic material oxygen consumption fermentation into organic fertilizer.

Organic fertilizer compost windrow turner is a kind of organic fertilizer which can store poultry excrement, agricultural waste, filter mud, sludge, domestic garbage and other pollutants through the principle of oxygen consumption fermentation. It can be heated in one day, deodorized in 3-5 days, (can kill eggs and other pathogens in feces) and become fertilizer in seven days. It is faster and more efficient than other mechanical fermentation methods. According to the requirements of customers, some auxiliary facilities, such as automatic sprinkling device, can also be used.

Ground stacking fermentation mode is a fertilizer making mode which can save civil engineering and human resources. It is necessary to stack the materials into long strip stacks, and the materials are stirred and broken by the compost organic fertilizer machine regularly, and the organic matter is decomposed under aerobic conditions. With the function of crushing, time and labor are greatly saved, and the production efficiency and product quality of organic fertilizer plant are significantly improved, and the cost is greatly reduced. When the tipper works, it can effectively mix sludge, chicken manure and other materials with bacteria and straw powder. It creates better aerobic for material fermentation. It is not only much faster than deep trough fermentation, but also effectively prevents the production of hydrogen sulfide, amine gas, and other harmful and malodorous gases in fermentation, which meets the requirements of environmental protection. 

How many tons of pig manure to produce one ton of organic fertilizer? What processing equipment is needed? Generally speaking, when processing pig manure into organic fertilizer, if the raw material humidity remains constant, one ton of organic fertilizer will be produced for every two tons of pig manure.

The equipment for producing pig manure organic fertilizer includes: fermentation tipping machine, forklift silo, crusher, screening machine, automatic packaging scale, belt conveyor, etc.

There are various types of pig manure dumping machines, such as track type dumping machines, slot type dumping machines, wheel disc dumping machines, chain plate dumping machines, etc. Their prices are different. It is necessary to first determine which type of dumping machine is suitable for oneself before determining its price. In addition to differences in models, there are also several factors that affect price:

1. Manufacturer

Manufacturer factors can lead to certain differences in prices. Generally, powerful manufacturers are more standardized when manufacturing equipment. In order to create a good user reputation for their own enterprises, they often choose raw materials with caution, and the quality of raw materials will be screened to a certain extent. The produced pig manure tipping machine has better quality, low failure rate, and good usage effect. But the price is often a bit higher than some second rate small factories, because small production enterprises are likely to put in effort in raw material costs in order to reduce costs and increase competitiveness.

2. Different methods of fermentation equipment

The fermentation methods of organic fertilizers can be divided into three categories: strip pile fermentation, tank fermentation, and fermentation tank fermentation. Each fermentation method uses different fermentation equipment. The strip type fermentation uses a self-propelled tipping machine, the tank type fermentation uses a tank type fermentation tipping machine, and the fermentation tank fermentation uses specialized organic fertilizer fermentation tank equipment. The prices of the three are generally the most expensive in fermentation tanks, followed by self-propelled fermentation, and tank fermentation is the most cost-effective and commonly used.

3. Equipment output per hour

After determining the fermentation method, the selection range is basically narrowed down to a specific category. Then you need to choose specific equipment specifications based on your predicted annual output, such as slot type flip machines, which have widths ranging from 3 to 10 meters. The larger the output, the larger the equipment size you choose. The price of a pig manure flipper below 5 meters is 30000 to 50000 yuan, while those above 5 meters are even more expensive at 50000 to 100000 yuan. So, the final equipment price is still determined by production capacity and output.

Disc granulator is widely used in various industries. It is also the common granulation equipment of NPK fertilizer production line and the core of fertilizer production process. Let’s talk about how to deal with the problem of poor output of equipment.

Controlling the water content of granulation particles

According to the characteristics of the powder, such as composition, fineness, viscosity, humidity and temperature, the moisture content of the particles should be controlled at about 30-28%.

(1) If the water content is too much, the product made by disc granulation mechanism has many big balls, and the surface of the ball is sticky and easy to block the screen surface;

(2) Suitable water content, more pellets and high yield;

(3) Too little water content, difficult to ball, low yield.

The following is the detailed production process of the organic fertilizer production line equipment for poultry and livestock manure:1. Fermentation tipping machine: After mixing the raw materials, the poultry and livestock manure is flipped during the fermentation process to ensure full and uniform fermentation of the poultry and livestock manure;2. Semi wet material crusher: finely crush the fermented poultry and livestock feces, crushing the raw materials of poultry and livestock feces to the required fineness before granulation;3. Horizontal mixer: Add the crushed poultry and livestock manure raw materials to the corresponding auxiliary materials for uniform mixing;4. Organic fertilizer granulator: The stirred poultry and livestock manure raw materials are granulated, and there are various models of granulators that can be reasonably selected based on the characteristics of the raw materials and the required variety of particles;5. Drying machine: The prepared organic fertilizer particles of poultry and livestock manure flow into a rotary dryer, drying their original moisture content to below 15%, increasing their particle strength and facilitating storage;6. Cooling machine: The dried organic fertilizer particles from poultry and livestock manure flow into the cooling machine, quickly cooling and shaping;7. Drum screening machine: There may be some substandard particles that are too large or too small in the organic fertilizer particles made of poultry and livestock manure. The screening machine is used to screen them out, and the substandard particles are returned to the corresponding process for particle reconstruction. Qualified poultry and livestock manure particles flow into the next process.8. Coating machine: Use a coating machine to evenly spray a layer of coating agent on the periphery of particles, which can effectively supplement the trace elements of the product and improve its brightness and fullness.9. Automatic packaging machine: Use an automatic quantitative packaging machine to package the finished poultry and livestock manure organic fertilizer particles into bags and transport them to the finished product workshop, completing all production processes.
