Why can you use cow dung to make organic fertilizer?

Cow manure belongs to organic waste, which will cause negative effects under improper handling. Therefore, as one of effective ways to dispose cow manure, making organic fertilizer from cow manure will be best choice for you. And this characteristic depends on two aspects:

  •  Advantage of cow manure: Cattle manure contains amounts of grass and grain, which is rich in nutrients and organic materials. Meanwhile, there are many enzymes and microorganism in it. Therefore, wide sources, low cost and high nutritive values make cow manure become good raw materials of organic fertilizer.
  • Harm of direct use: Because of high ammonia content and excess salt content, the direct use of cow manure will do harm to plants. Hence, you should convert it to organic fertilizer, so as to fully utilize its nutrients.

Given the above, you can make organic fertilizer from cow dung, which will improve soil condition, provide nutrients for plants and promote output of crops. The following is detailed introduction of cow dung processing machine.

What preparations should you do for manufacturing organic fertilizer from cow dung?

Composting is an important procedure for you to initially dispose cow manure. For fresh manure with 80% water content, you should dehydrate it to 50%-60%water content by Tongda solid-liquid separation machine or adding moderate crops straws or rice hull. On the contrary, for dried manure, you should add some water to adjust water content to 50%-60%. After this, you can make a compost.

Three methods for composting cow dung with cow dung processing machine

  • Windrow type aerobic composting: you should pave organic raw material with windrow type. And the windrow compost pile is usually 1.5 to meters wide, 0.8 to 1.4 meters high and 50-150 meters long, which depends on compost site. Under this condition, Tongda windrow type compost turner, like crawler compost turner and self-propelled compost turner, will be your good assistant.
  • Groove type composting: It means you can put all raw materials in one groove for fermentation. The groove usually work with groove type compost turner, such as rail type compost turner, wheel type compost turner and chain plate type compost turner. In addition, with the help of Tongda compost turner, cow dung in fermentation groove can ferment in good environment conditions.
  • Composting with Tongda fermentation pot: As we all know, cow dung will produce amounts of odors, which may cause air pollution. What’s more, compost piles on ground will occupy plenty of space. Therefore, you can choose Tongda fermentation pot, which provides a closed aerobic fermentation environment for raw materials. Tongda fermentation pot with air supply system, temperature and oxygen concentration occupies less space. What’s more, you can customize proper size according to your requirements.

Two available methods to covert cow manure into fertilizer for commercial purpose

After composting, cow manure has become organic fertilizer. If you want to produce commercial cow dung fertilizer, you can make cow manure fertilizer powder or pellets. Meanwhile, both of them are convenient for storage and transportation. Here, you can choose cow dung fertilizer powder production line or pellets production line. And we will offer you detailed information below.

Cow dung granular organic fertilizer production line with Tongda processing machine

Compared with powdery production line, granular organic fertilizer production line is more complex and involves more equipment. It means you need invest more money and space for organic fertilizer production. This production line contains the following steps and cow dung processing machine.

crushing and mixing process

  • Crushing: This step is same with that of powdery production line. It will crush large blocks of raw materials, which is the preparation for granulation. With the exception of rotary screen machine, you can also choose Tongda High output hammer crusher, which is the preferred crushing machine for large-scale production of organic fertilizer.
  • Mixing:  In this step, mixer evenly blends raw materials, which creates uniform fertilizer effects and makes preparation for granulation.

  • Boundary dimension (mm): 2260*1650*2250

Drying and cooling process

In this step, you can cool the temperature of cow dung pellets and remove parts of moisture in pellets. Besides, you can adopt Tongda rotary drum drying machine, rotary drum cooling machine and natural gas burner or hot blast furnace. At the same time, the three machines are used together. Natural gas burner or hot blast furnace offer hot wind to rotary drum drying machine, which can dry cow dung pellets and evaporate some moisture. Rotary drum cooling follows the drying machine, which is used for further removal of moisture and lowering temperature.

In addition, you also can apply dust collector in this step. Meanwhile,  Tongda can provide you cyclone dust collector, which can collect dust from drying and cooling process, and water curtain dust collector for secondary dedusting. what’s more, the later equipment collects tiny particles by water curtain from spray headers.

Screening process

This step is similar to that of powdery production line, and you can remove unqualified pellets by it. In addition, you can apply vibrating screen machine, which adopts the cylindrical eccentric shaft oscillator and the partial block to adjust the amplitude. Moreover, it is featured with long materials screening line and multiple screening sizes.

Coating process

As one type cow dung processing machine, the one purpose of coating is for beautiful appearance. On the other hand, you can add some other materials, like drugs for prolonging storage time.

  • Rotary coating machine: Tongda coating machine consists of spiral conveyor, mixing tank, oil pump and main engine. Meanwhile, it adopts powdering powder or liquid coating process, which can be used for preventing caking of organic fertilizer.

Tips for selection of organic fertilizer production site

The selection of plant site is also an important factor for organic fertilizer production. Because it may influence the production cost. Firstly, if circumstances allowed, you can build your plant near the source of raw materials, like cattle farm or livestock farm. Secondly, the plant should slightly far away from residential area, because of odors may be produced in manure fermentation. Thirdly, the ground in the plant shall be concrete, which can prevent soil from manure pollution. Finally, the ground in the plant shall be flat, or it will cause harm to organic fertilizer making machine. Because the operation of machines needs a stable support.
