Making Biofertilizer from Cow Dung – Cow Dung Composting

During cattle breeding, if cow manure is not processed in time, it will cause air pollution, breed a large number of mosquitoes and flies, pollute the surrounding environment of the farm, and cause cattle diseases. Through cow dung composting treatment, turning waste into treasure can also bring huge benefits.

Making cow dung into organic fertilizer is one of the main methods to deal with cow dung. Dried cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free leaching and 15%-30% crude fiber, and has a high nutritional content. The organic fertilizer production line can efficiently convert cow manure into organic fertilizer.

1. Cow dung composting, fermentation is the first step.

A cow’s cow manure needs 4 to 6 cubic meters of space a year. According to the breeding scale, a reasonable construction of cow dung accumulation and fermentation sites will be carried out. Add 10%-15% of straw, rice bran and other auxiliary materials to the cow dung, and add appropriate amount of water to control the water content of the cow dung to about 60%. Inoculate the fermentation agent, and the fermentation time is 15-40 days (depending on the season).

In the fermentation process of cow dung composting, turning and throwing is an important link. The purpose of turning and throwing is to make the material fully mixed, and make the material fully contact with the air through turning and throwing to achieve the best fermentation effect.Wheel Type Compost Turner, Chain Plate Compost Turner, Groove Type Compost Turner, Moving Type Compost Turner, Crawler Type Compost Turner, Tractor-pulled Compost Turner, Horizontal Fermentation Tank, Vertical Fermentation Tank.

You can then choose to process cow dung composting into two forms. Powder or granules. But whether you want to make cow dung into powder or granular fertilizer, you need to crush the feces material into fine powder. -In terms, fine powder organic fertilizer is easy to transport and store compared to cow dung compost. On the other hand, the finer the cow dung powder, the smoother the final fertilizer particles.

2. Raw material crushing

The fermented materials and other additives are crushed, mixed, and mixed in a certain proportion through material crushing, batching, and mixing machine. The function of this system is to crush, mix and stir compost materials, nitrogen, phosphorus, potassium inorganic fertilizers and other additives in a certain proportion. Based on years of experience, the following equipment is recommended:

Semi-wet material crusher

This machine is mainly used to crush biofermented organic fertilizer materials with a moisture content of 25% to 50%. It has a good effect on crushing hard materials such as glass bricks, ceramics, and gravel.

Horizontal mixer

The horizontal mixer stirs the materials in batches and mixes them evenly. The mixing rate is high and there is little residue. It is suitable for mixing feed, concentrated feed, and premix additives.

3.Cow dung composting , Pelleting

A new organic fertilizer granulator is used to granulate materials. This organic fertilizer granulator is the latest technical product accumulated by our company’s years of R&D experience. It can not only process fertilizer powder into granules, but also achieve better granulation effect on acidic sludge and urban sludge.

4. Dry, cool, sieving

After granulation, the fertilizer has a high moisture content, so the organic fertilizer rotary dryer needs to be used to further remove the water to make the organic fertilizer moisture meet the standard requirements.

The slewing cooler is used to cool the particulate material, which is conducive to transporting heat from the top of the dryer to the countercurrent cooler to store. Under the action of the cooling fan, dry air enters from the lower part of the cooler and fully exchanges heat with the upper and lower wet and heat particles.

There is a certain difference in the size of particles output from the granulation molding system and screening and grading is required. The roller screen machine has the advantages of low vibration, low noise, and easy to change screens. An automatic feedback system is installed during the production process of organic fertilizers, which screen unqualified large and small particles, convey them through a belt hoist, re-pulverize them and then feed them into the granulator to continue granulation, which helps to improve the continuous operation capability of the production line.

5. Packaging

The packaging machine performs quantitative weighing and packaging of particulate materials. Automatic quantitative packaging of powder and pellet materials is suitable for flour, starch, feed, food, chemical, light industry, building materials and other industries.

Using cow dung as raw materials to produce organic fertilizer has the advantages of low cost, stable quality, loosening of soil, improving land consolidation, and improving soil fertility, and has huge market space. As a leading fertilizer machinery manufacturer in China, we have professional organic fertilizer production processes that can efficiently and efficiently convert cow dung into organic fertilizer.
