Applications Of Cow Dung Pellet Machine & Pellet Production Line

Cow dung

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.

Working Principle Of Cow Dung Pellet Machine & Pellet Production Line

The ring die cow dung pellet machine is mainly composed of feeding, mixing, granulating, transmission and lubrication systems, etc. It is used to develop the wet powder into the required pellets, and it can also crush the bulk dry powder into the required pellets.

During the working process of cow manure pellet machine die and the roller, the ring die is driven by the main power of the motor to rotate clockwise at a certain speed; as material enters the granulating chamber, the material starts to be taken into the working area, and the cattle manure pellet granulator pressure roller is also driven by friction. With the rotation of the die roll, the ingested material moves forward faster, and the extrusion force and the density of the material gradually increase.
cow dung pellet making machine

When the extrusion force is increased enough to overcome the friction between the material in the die hole and the inner wall, the material with a certain density and cohesive force is squeezed into the ring die hole. Due to the continuous rotation of the die and roll, the material is continuously squeezed into the ring die hole. Therefore, the material in the ring die hole is continuously squeezed out of the ring die hole after being formed, and is cut by the cutter to form organic  cow dung fertilizer pellets or cow dung fuel pellets.

Complete cow dung pellet production line manufacturing process

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 processing line. When cow dung is used as biomass energy, you can directly refer to: Biomass pellet production line.

Cow dung pellet production line 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.

  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 pellet bagging machines

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.

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.
Cow manure pellet making process

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.

  2. Advanced material blending technology and biological fermentation system.
  3. The best formula for special cow manure fertilizer (which can be flexibly designed according to the local soil and crop characteristics.
  4. Reasonable secondary pollution (waste gas and odor) control technology.
  5. Design and manufacture technology of cow manure fertilizer making equipment.cattle cow manure factory

Share a few cow dung production factory projects we have done:

Beef cow dung VS dairy cow dung, which is better for cattle manure fertilizer factory production?

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 vs chicken manure, which is better for farming and plant growth?

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. 
cow dung and chicken manure pellets fertilizer

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.
cow dung fertilizer making equipment

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.
