Cow dung as a raw material is essential in the fertilizer production line. It is high in nutrients and has a good nourishing effect on the soil. Moreover, its output is large, and its cost is also within a controllable range. Therefore, the cow dung production line is very popular with fertilizer manufacturers. Our company has a full set of production line equipment for you to choose from. For details, please see the introduction below.

How to make cow dung into fertilizer?

You can see cow dung everywhere on the farm, but those farm people sometimes don’t know how to deal with the cow dung better, so that they can play beyond their original value. At this time, some people will make them into fertilizer. But how do you turn cow dung into fertilizer?

  • First of all, you cannot turn fresh cow dung directly into fertilizer, you need to transform it. The cow dung is dehydrated, fermented and decomposed, and the temperature is raised rapidly to achieve the initial effect.

  • Secondly, if the size of the material is inconsistent, you need to crush, and screen the crushed material to select a suitable material.

  • Then make fertilizer according to customer needs. It can be a powdered fertilizer so that you can pack directly after sieving. It can also be granular fertilizer, which you need to granulate, dry and cool before packaging.

This is the complete process of making cow dung into fertilizer.

Types of cow dung production line for your requirement

Cow manure production line is divided into two types: powder fertilizer production line and granular fertilizer production line.

Powdered Fertilizer Making Plant

Dehydrating the excess water in cow manure. Then carry out aerobic fermentation to quickly decompose, so that the fertilizer can hold the water but not drip. You can use our company’s organic fertilizer fermentation tank, which has professional electronic control equipment to ensure a more accurate fermentation effect. You must crush and screen all materials to select materials suitable for subsequent fertilizer making. Because it is in powder form, you can directly package and bin after sieving.

Granular Fertilizer Production Line

The previous steps are the same as the powder production line, but there is a difference in the granulation step. Because there are two granulation processes: dry granulation and wet granulation. For dry granulation, it is recommended that you can buy our company’s double-roll granulator, which is suitable for this process. And you can directly package later to reduce costs. For wet granulation, if your output is large, it is recommended that you buy a drum granulator. If the output is small, buy a disc granulator. Because of wet granulation, you need to dry and cool later. Finally it’s ready to pack.

You can choose the production line that suits you according to your needs.

How to improve drying efficiency in your cow dung production line?

In the cow dung production line, the efficiency of the dryer is closely related to the economic benefits of the customer. Improving its efficiency is the key issue to improve the economic benefits of customers.

The cow dung drying operation is realized through the contact and exchange of wet cow dung and high-temperature air. If the heat in the drying cylinder is insufficient, the cow dung cannot absorb the heat required for drying in a short time, which will inevitably reduce the drying rate, thereby affecting the output of cow dung drying. Therefore, ensuring the adequacy of heat in the cow dung dryer is a key factor to improve the efficiency of the cow dung dryer.

During the drying operation of cow dung, the cow dung material is continuously turned up and down with the rotation of the drying drum, which promotes the full contact between the material and the hot air flow, thereby speeding up the drying speed of cow dung. Therefore, designing a suitable lifting plate device in the cow dung dryer to increase the contact area between the material and the high-temperature airflow is also a measure to improve the efficiency of the cow dung dryer.

For any equipment, in order to improve its work efficiency, it is necessary to achieve correct and standardized operation, and the same is true for cow dung dryers. The staff must keep the dryer feeding at a uniform speed, scientifically and reasonably adjust the air volume inside the dryer, and solve the sudden problems in the drying of cow dung in time, so as to better ensure the drying of cow dung efficiency and quality.

Cow dung fertilizer production price

Due to the different output of cow dung production line, the price is also different. Below I will help you make a simple plan according to different output, and provide you with some suggestions.

Powdered Cow Dung Production Line

Output:1-3 tons per hour   Budget:35,000 US dollars   Site:800 square meters

Output:5 tons per hour   Budget:45,000 US dollars   Site:1500 square meters

Output:10 tons per hour   Budget:60,000 US dollars   Site:3000 square meters

Output:20 tons per hour   Budget:90,000 US dollars   Site:5000 square meters

According to the fertilizer status of this production line, the required equipment includes:compost turning machine, feeding machine, vertical pulverizer, screening machine, packaging machine, belt conveyor. From the above, the budgets and site sizes for different productions are also different.

Granular Cow Dung Production Plant

Output:1-2 tons per hour   Budget:110,000 US dollars   Site:2,000 square meters

Output:3 tons per hour   Budget:140,000 US dollars   Site:3,000 square meters

Output:5tons per hour   Budget:190,000 US dollars   Site:24500 square meters

Output:10 tons per hour   Budget:360,000 US dollars   Site:5500 square meters

Output:20 tons per hour   Budget:550,000 US dollars   Site:10,000 square meters

According to the fertilizer status of this production line, the equipment required for 1-5 tons includes: compost turning machine, feeding machine, vertical crusher, two of screening machine, batching machine, stirring tooth granulator, drying and cooling machine , coating machine, packaging machine, belt conveyor. Due to the large output of 10-20 tons, the granulator becomes a drum granulator and a disc granulation machine.
