Cow Dung Pellet Making Machine

When processing cow dung pellets, cow dung can be used as the core raw material, but other auxiliary materials or functional materials are usually needed to optimize the physical properties, nutritional ratio or specific performance of the pellets.

For example:

Cow dung has a high moisture content (70-80%), and direct pelleting is easy to stick to the mold. Straw and sawdust (10-30%) need to be added to reduce humidity and enhance air permeability.

The carbon-nitrogen ratio of cow dung (C/N≈20:1) is ideal, but the nitrogen, phosphorus and potassium content is low (N 0.5-1.5%, P 0.2-0.5%, K 0.5-1%), and minerals (such as phosphate rock powder) or high-nitrogen raw materials (such as soybean meal) need to be added.

In addition, when processing cow dung pellets, the raw materials can be mixed with chicken manure, sheep manure, horse manure and other various animal manure and agricultural and forestry waste.

Yes, but certain conditions must be met.

Cow dung can be made into fuel pellets through cow dung pellet making machine after proper treatment, but its calorific value and combustion characteristics are different from those of wood pellets. The following key points should be noted:

Low calorific value:

The calorific value of pure cow dung pellets is about 12-14 MJ/kg (wood pellets are usually 16-18 MJ/kg), and high calorific value materials (such as wood chips and straw) need to be mixed to increase the calorific value.

Recommended formula: cow dung (50%) + wood chips (40%) + starch adhesive (10%), the calorific value can reach 14-16 MJ/kg.

High ash content:

The ash content of cow dung after combustion is about 10-20% (wood pellets <2%), so it is necessary to choose an ash-resistant boiler or clean the furnace regularly.

Pretreatment required:

Drying: The moisture content needs to be reduced to <15% (fresh cow dung contains 70-80% moisture).

Deodorization and sterilization: High temperature (＞70℃) or adding lime to inhibit odor and pathogens.

Usually the same ring die cow dung pellet making machine, but the process parameters need to be adjusted.

(1) Applicability of fuel pellets:

Suitable for industrial boilers or mixed combustion (such as mixing with coal/wood chips), home heating stoves may be easily clogged.

Must comply with local fuel standards (such as EU ENplus or US PFI).

(2) Regulations for organic fertilizer pellets:

Must be thoroughly decomposed (GI>80%) to avoid root burning.

Heavy metals (such as arsenic and cadmium) must be lower than agricultural standards.

(3) Equipment adjustment suggestions:

When switching products: need to clean the mold and adjust the roller pressure (fuel pellets require higher pressure).

Maintenance frequency: Cow dung has a high sand content and the mold wears quickly, so the cow dung pellet making machine ring die and roller need to be checked regularly.

Whether cow dung is more suitable to be processed into organic fertilizer pellets or fuel pellets needs to be comprehensively evaluated based on raw material characteristics, market demand, policy support and economic feasibility.

1. Analysis from the perspective of raw material characteristics

Cow dung is naturally suitable for making organic fertilizer, but additional processing is required for processing into fuel. The calorific value is low (12-14 MJ/kg), and needs to be mixed with sawdust to increase the calorific value.

2. Analysis from the perspective of application scenarios

(1) Advantages of organic fertilizer pellets

Agricultural demand: Improve soil structure, especially suitable for degraded farmland (such as saline-alkali land in China and barren soil in Africa). In line with the trend of organic agriculture (EU/China policy promotion).

High added value: High-quality organic fertilizer is sold at $200-500/ton (much higher than $80-150/ton for fuel pellets).

(2) Advantages of fuel pellets

Energy substitution: It can be used as a cheap fuel in areas with a shortage of electricity and coal (such as rural India). Co-firing with coal can reduce carbon emissions (piloted in some European power plants).

Simple processing: No need for composting, shortening the process (but strict drying is required).

3. From the perspective of economic analysis

4. Investment advice

(1) Situations where organic fertilizer pellet processing is preferred

Local organic farms, fruit and vegetable bases or soil remediation projects.

Policy support (such as subsidies, tax exemptions).

The source of cow dung is stable and has high nitrogen and phosphorus content.

(2) Situations where fuel pellets are preferred

Energy shortage (such as areas without grid coverage).

Mature market for mixed combustion (such as European biomass power plants).

Lack of sales channels for organic fertilizers.

Nowadays, cow dung pellets are mainly used as organic fertilizer and biomass energy, but the process and equipment of the two types of cow dung pellets are very different. Since cow dung is mainly used as organic fertilizer, the content of this page mainly expands the content of the cow dung organic fertilizer production line. When cow dung is used as biomass energy, you can directly refer to: Biomass pellet production line

1. Cow dung pellet production line process design for cow dung fertilizer pellets

Many studies at home and abroad have shown that as fertilizer, livestock manure can not only solve the way out of waste, but also improve and fertilize the soil. Therefore, it is an ideal disposal method and is generally favored by countries all over the world.

However, if the livestock and poultry manure produced by large-scale breeding is directly sold as fertilizer, it is often difficult to form a market due to high transportation costs and inconvenient operations.

On the basis of the harmless and stabilizing treatment of livestock and poultry manure, processing it into commercial organic fertilizer or organic & inorganic compound fertilizer has a stable product market and is a resource-based approach that conforms to the national conditions of many countries.

Do you want to know how to use the cow dung fertilizer machine to make cow manure balls? Then we will tell you the main process about the cow manure fertilizer pellet production.

If you want to get the granulated cow manure, you should have the cow manure fertilizer powder before. And how can you get the powdery cow manure? You had better use a compost turner to help you get it. After that, you can get the fermented cow manure fertilizer powder by using the organic fertilizer compost turner.

The powdered cow manure fertilizer is uniformly fed into the cow dung pellet making machine-new type through the conveyor belt. Finally, the high speed rotary mechanical stirring force and the resulting aerodynamic force will turn the cow manure fertilizer powder into fertilizer pellets quickly.

1. Fermentation section
   Collect cow dung and cow urine, mix with hay and decaying silage to make compost, and let it ferment. In the fermentation process, the dumper is used to fully ferment the cow dung, which can only be achieved by timely and even dumping. If some places are very dry and some places are very wet, this will affect the quality of fermentation.
2. Raw materials crushing and mixing section
   Use the batching bin to crush, proportion and mix the composted materials, N, P, K and other inorganic fertilizers, and other additives and other raw materials in a certain proportion through a material pulverizer and a horizontal cow dung mixer.
3. Granulation section
   Use a special organic cow manure fertilizer pellet machine to granulate the material.
4. Screening section
   The granules output from the cow dung pellet making machine system have certain differences in particle size and need to be sieved and classified. The selected rotary screening machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to be equipped with an automatic return system to screen unqualified large and small particles, convey them through a belt elevator, and send them to the pelletizer to continue pelletizing after re-pulverization, which helps to improve the continuous operation capacity of the cow dung pellet production line.
5. Drying section
   Use a cow dung dryer machine to further remove water from the sieved particles to meet the standard requirements of organic fertilizer moisture content.
6. Cool section
   Cooling the cow manure pellets with a cooler helps the storage and quality of the granules.
7. Packaging section
   The cooled cow dung manure pellets are transported into the finished product warehouse through the conveyors. Cow dung pellets can be quantitatively weighed and packaged through automatic packing scale.

Cow dung, from the point of view of cattle farms, is a kind of waste. Can cow dung be re-developed and fully utilized? It has become the focus of people's attention. However, this problem is no longer a difficult point. As many countries and regions attach importance to this aspect, in order to develop the organic fertilizer industry, various advocacy and encouragement policies have emerged, and the time for the large-scale and industrialized development of cattle manure commercial organic fertilizer has become more and more mature.

Cow dung can be made into high-quality organic fertilizer products after fermentation. Cow manure contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus, and 0.10-0.15% potassium. Cow manure organic fertilizer is a cold fertilizer. The organic matter and nutrient content is low in all kinds of livestock. It has a fine texture, slow decomposition, and low calorific value. It is a late-acting fertilizer and is suitable for base fertilizer.

2. Cow dung pellet plant for cow dung biofuel pellets

After the cow dung is processed and pelletized, it can generate more than 3,500 calories after burning as a biomass pellet, which is almost the same as the lignite produced in many countries and regions, but the cost can be reduced by 30%, and more Environmental protection, the small amount of manure ash produced after combustion can also be used as organic fertilizer, which can achieve zero waste discharge in the whole process.

1. Cow dung drying
   Different from making other biomass fuel pellets, the first step for making cow manure fuel pellets would be drying. Because there is too much water contained in the cow manure. If crush the cow manure first, the too wet manure may probably block the crushing machine. After drying, the moisture of mature is decreased to below 15%.
2. Manure crushing
   After drying, the manure will become loose and can be processed by the crushing machine. The crushing machine will pulverize the cow dung into powder with the diameter of 2-5mm.
3. Manure pelletizing
   When the manure powder is fed into the manure pellet machine, it will be pressed by the great pressure inside the pellet machine. Then cattle manure fuel pellets are made. Ring die series pellet mill for cow dung pellets production is available for your selection. Whether to choose the small one or large one depends on your own needs.
4. Pellets cooling
   Cow dung fuel pellets discharged from the cow manure pellet mill are high in temperature and moisture content, then goes the cooling step. After that, the pellets can be burned in the boiler, or used as fertilizer in soil. The pellets can also be sieved when cooling, so that poor quality pellets and powder materials will be collected and reproduced.
5. Pellets packaging
   Once the cow dung fuel pellets are formed and cooled, they can be packaged in bags by cow dung bagging machine or stored in bulk.

Compared with other fuels, cow dung is cheaper than propane, most natural gas and electricity. In addition, it is also very effective. Where wood is very scarce, cow dung can be used as a substitute and used to reduce wood consumption pressure. In addition, cow dung requires a short collection time and is easy to obtain. Cow dung contains a reasonable amount of energy and can be used as a sustainable and renewable fuel source. It can also reduce the disposal costs of odors and other nuisances associated with large-scale farms.

Because of the many disadvantages of directly using cow dung as fuel, cow dung fuel pellets seem to be a better choice. After pelletizing, the volume of cow dung fuel pellets is three times smaller than the original volume, but the burning time will be extended by three to four times. During the combustion process, no obvious dust or ash is discharged, and the density of the discharged ash is much lower, which can meet environmental protection standards.

Cow dung is a waste produced by many cattle farms. A large dairy farm may produce tens of tons of cow dung a day. If it is not treated in time, it may pollute our environment and water sources. After analyzing cow manure, it is found that it is rich in minerals and nutrients, and the organic content is higher than chicken manure. This is why many people make cow manure into fertilizer pellets.

Studies have found that cow dung is the best choice for pelleting by cow dung pellet making machine. Cow dung can not only be made into fertilizer pellets, but also into fuel pellets. This is because cows eat a variety of foods, such as grass, leaves, grains, wheat straw, etc., and chew the food thoroughly. Therefore, cow dung is composed of many combustible fibers, and it is also a good choice to make fuel pellets.

• Improve the soil and fertility. After the cow dung organic fertilizer is applied to the soil, the organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the soil's fertilizer retention and fertilization capacity and buffer capacity, and create good soil conditions for crop growth.
• Improve the utilization rate of fertilizer.
• Increase output and improve quality. Cow dung organic fertilizers are rich in organic matter and various nutrient elements to provide nutrition for crops. After the cow dung organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.

• Wide application. Cow dung fuel pellets can replace coal to be used to supply heat or as fuel. It is especially suitables for densely inhabited district.
• It has no season limitation and can be used all the year round.
• Making cow dung fuel pellets can reach conversion and appreciation of waste material.
• Environmental friendly. As one green energy, sulphur content, ash content and nitrogen content of cow dung fuel pellets is much lower than coal, fossil oil, etc.
• Low cost and high additional value. With locally abundant cow dung and cow dung pellets production line, you can make cow dung fuel pellets.
• Big density and convenient to store. Cow dung fuel pellets has small volume and high density which makes it convenient to convert, store, transport and use.

There are many types of cow dung, and the purpose of cow dung is mainly from the way it is processed. Generally, the cow dung in large farms will be treated, not the cow dung released from the steak, such as solid-liquid separation after washing, such as using litter such as sand, soil, etc. as the litter, such as using bacterial residue as the litter.

In addition, the manure of beef cattle is different from that of dairy cows. The manure of dairy cows has higher organic matter and nutrients, and the organic matter of beef cattle is lower. Pure cow manure is a very good raw material as organic fertilizer and microbial fertilizer carrier. Because of its moderate carbon-nitrogen ratio between 20 and 35, it first needs to control the water content between 50-65.

Fermentation bacteria are usually withered grass and wood. Mold, Aspergillus niger and Aspergillus oryzae are better combined. After 30 days of aerobic fermentation, the fermentation will be good. After the moisture is controlled, the nutrition and other technical indicators can be used as commercial organic fertilizer and microbial fertilizer.

Cow dung has less protein content and more grass fiber. It is suitable for places where the soil is sticky and needs improvement. It can effectively increase the air permeability of the soil and supplement nutrients. It is suitable for crops that require loose and fertile soil! It is more suitable for foliage plants.

Chicken manure has high protein content, high calories, more comprehensive nutritional elements, suitable for soil physical properties, and places where nutrients are incomplete or low, which can effectively supplement the growth needs of plants, and is more suitable for flowering and fruiting plants.

The main components of cow manure and chicken manure are different. Generally speaking, cow dung contains more crude fiber, because cows mainly feed on grass. Chicken manure is generally finer and usually includes some undigested feed.

If these two kinds of manure are used as fertilizer, they must be fermented, which is commonly referred to as compost, to reduce odor and increase fertilizer efficiency. Both are considered organic fertilizers. After composting, chicken manure is more effective.

However, it should be noted that chicken manure is rich in organic matter, which is good for crop growth. It also contains fiber and carbohydrates. However, if chicken manure is used as fertilizer, the dosage must be controlled because chicken manure is acidic. Yes, if it is used too much, it will cause soil acidification, reduce crop yields, and may also cause the roots of crops to corrode.

The output of chicken manure is relatively small, and it is unrealistic to use chicken manure for fertilization, so generally straw is used as fertilizer first, and then chicken manure is used as additional fertilizer.

Compared with chicken manure, the nutritional value of cow manure is not so high. Although it contains a certain amount of organic matter, the organic matter cannot be decomposed, and the oxygen and nitrogen contained in it are much lower than chicken manure.

However, cow dung has an incomparable benefit to chicken dung, that is, although it is relatively weak in fatness, it is relatively mild in nature, and has the characteristics of ventilation, so it can be used on poor soils to improve the soil. The quality of the fertilizer is generally used together with horse manure, and then an appropriate amount of phosphate rock powder is added to it to get the best fertilizer efficiency.
