TONY Design Cow Dung Production Line Specification

If cow dung is left in nature without management, it will cause many harms, mainly including the following aspects:

1. Environmental Pollution

Air Pollution: If cow dung accumulates in the natural environment, a large amount of harmful gases will be produced due to the decomposition by microorganisms. For example, ammonia and hydrogen sulfide will be released. Ammonia has a pungent odor and will have a negative impact on the surrounding air quality, causing people to feel uncomfortable, such as irritation to the eyes and respiratory tract. Hydrogen sulfide is a highly toxic gas. It has the smell of rotten eggs at low concentrations, and at high concentrations, it can cause olfactory paralysis in humans. It will cause serious damage to the human nervous system and respiratory system.

Water Pollution: Organic substances, pathogens and other substances in cow dung can easily enter water bodies under the influence of rainwater erosion or other means. For instance, when nutrients such as nitrogen and phosphorus in cow dung enter lakes and rivers, eutrophication of water bodies will occur. This leads to a large reproduction of plankton such as algae in the water, further resulting in the deterioration of water quality and a decrease in the dissolved oxygen in the water body, which causes a large number of deaths of aquatic organisms such as fish. Meanwhile, pathogens such as Escherichia coli and Salmonella that may be carried in cow dung will also pollute water bodies and spread diseases, posing a threat to the health of humans and livestock.

Soil Pollution: Although cow dung itself contains certain nutrients, excessive accumulation of cow dung will change the physical and chemical properties of the soil. For example, it will make the soil less permeable to air because the accumulation and compaction of cow dung will block the air from entering the soil pores. Moreover, a large amount of cow dung will lead to the accumulation of salts in the soil, affecting the normal activities of soil microorganisms. If cow dung contains heavy metals (for example, when cows consume contaminated feed and accumulate heavy metals in their bodies), these heavy metals will also accumulate in the soil, causing heavy metal pollution in the soil and being transmitted to other organisms through the food chain.

2. Disease Transmissio

Cow dung contains a large number of pathogenic microorganisms, such as bacteria, viruses and parasite eggs. For example, Brucella can exist in cow dung. This pathogen can cause brucellosis in humans, and the symptoms include fever, excessive sweating and joint pain, seriously affecting human health. There is also Cryptosporidium, a parasite that can cause diarrhea in humans and animals. Its oocysts can contaminate the environment through cow dung and then infect other animals and humans. In addition, Mycobacterium bovis may also be transmitted through cow dung. Once infected, it will cause damage to the lungs and other organs of animals and humans.

3. Impact On Aesthetics And Public Health

In rural areas or around livestock farms, if cow dung is randomly piled up, it will make the environment dirty, messy and unpleasant. This not only affects the aesthetic appearance of the living environment of the surrounding residents but also breeds a large number of pests such as flies and mosquitoes. Flies can lay eggs and reproduce on cow dung and then spread germs everywhere. Mosquitoes may spread diseases such as malaria and deng(should be "dengue fever" in correct spelling), posing a serious threat to public health.

Cow Dung can be recycled in a variety of ways, ranging from simple reuse to complex chemical treatment. Here are some of the main recycling methods:

Production Of Organic Fertilizer

Composting Method: By controlling the conditions of composting, such as temperature, humidity and ventilation, cow dung can be transformed into a highly efficient organic fertilizer. Cow dung is mixed and piled up with other organic materials like straw and leaves in a certain proportion, and turned regularly to ensure sufficient oxygen supply inside the compost. Generally, it takes several weeks to several months for the cow dung to be fully decomposed. The decomposed cow dung fertilizer has a more balanced nutrient composition and a long-lasting fertilization effect, and is suitable for the cultivation of various crops.

Vermicomposting Method: Earthworms are used to decompose cow dung to make fertilizer. In a suitable container or site, cow dung and earthworms are placed together. The earthworms will consume the cow dung and convert it into nutrient-rich vermicompost. Vermicompost has fine particles, loose structure, is rich in humus and microorganisms, and has good air permeability and water retention properties. It is a high-quality fertilizer for flowers and vegetables.

2.Production Of Fuel Pellets

Cow dung fuel can be used not only for energy purposes such as heating and power generation, but also the ash left after combustion can serve as a high-quality fertilizer. This ash contains abundant nutrients such as potassium and phosphorus. When applied to farmland, it can improve soil fertility and promote the growth of crops. For example, in some rural areas, after using cow dung pellet fuel for heating, the ash produced is spread on the farmland, which can achieve a good fertilization effect, realizing the organic combination of energy utilization and agricultural production.

3. Production Of Silage Feed

Cow dung is mixed with other silage raw materials (such as corn stalks, forage grass, etc.), and after silage treatment, it can be used as feed for ruminant animals (such as cattle and sheep). During the silage process, microbial fermentation will create an acidic environment, which can inhibit the growth of harmful microorganisms and preserve the nutritional components of the feed. However, this utilization method requires strict control of the quality and treatment process of cow dung to ensure the safety and nutritional value of the feed.

The main reasons for using cow dung to make pellets include the following aspects‌:

The dehydration process of the cow dung processor is divided into two stages

The first stage is solid-liquid separation. After the liquid cow dung is pumped into the equipment, the spiral dragon first filters out most of the water, and the cow dung is concentrated to a solid state, preparing for the second stage of pressing.

The second stage is squeezing and dehydration. The solid cow dung enters the second stage for pressing. Under the squeezing action of the high-pressure spiral dragon, the water content of the cow dung is reduced to about 60%.

Add straw, branches, mushroom residue and other auxiliary materials to livestock and poultry manure in a ratio of 7:3, and adjust the carbon-nitrogen ratio and water content. Then sprinkle aerobic fermentation bacteria and let it ferment for about 25-45 days. During the fermentation process, the pile should be turned according to the temperature changes. It is recommended to use a compost turning machine to save labor costs and improve fermentation efficiency.

After 25-45 days of fermentation, the livestock manure becomes gray-brown and odorless. Large lumps, bones, pebbles, etc. in the material can be crushed using a vertical high-humidity material crusher.

Adding nutrients: In order to enrich the nutrients of organic fertilizer, you can add appropriate amounts of trace elements, humic acid and other nutrients. Dynamic batching machine can accurately control the amount of ingredients.

This process is mainly use TONY Disc Pelleting Machine to products organic fertilizer pellets.

Disc Pelleting Machine produces pellets through continuous rotation of the disc, the overall arc structure, and the granulation rate can reach more than 93 percent

The cow dung pellets need to be dried to remove excess moisture, and then cooled using a cooler to ensure the stability and storage time of the granules.

This process is mainly used to cool cow dung pellets from 80-90℃ to 20-30℃.Freshly produced cow dung pellets have a higher temperature and contain more moisture, which is not conducive to direct packaging storage and transportation. In the production line of biomass pellets, the cooling process is essential

In order to make the cow dung pellets uniform in size and sell at a higher price, the organic fertilizer particles must be screened. Organic fertilizer that does not meet the size must be returned to the crushing stage for re-granulation.

In this process, cow dung pellets are coated by TONY coater. Cow Dung pellets are added from the feed end, pass through the inside of the cylinder, and accelerate the air flow in the cylinder under the suction of the induced draft fan to complete the coating process
