Cow dung as a normal breeding animal, the output of the cow manure is much more. Evenly, a 50-cow farm can produce 1 ton cow manure every day. How to process the cow manure is a problem that puzzles many people. In agriculture, cow dung nourishes the plants and crops in many countries. Cow manure contains the plants needed nitrogen, phosphorus, potassium, organic matter, and fiber nutrients. Anyway your garden or your farmland is need the cow dung fertilizer for their growth.

Composting is the key and first step of making fertilizer. First, you should collect your cow manure in a pile or in the trench. Second, you should reduce the moisture of the cow dung to 50%-60%. If to much water will affect the fermentation. You can mix some dry agricultural waste such as straw, corn stalk, sawdust, etc. Also you can use a solid-liquid separator. Third, composting your cow manure. For small manure piles, you can easily turn it over. But with large amounts of cow dung, it’s a little more difficult. In this time, you need a compost turner to help you. As a fertilizer machine supplier, SX has six types compost turner which you can choose.

In the case of a large amount of cow dung production, basically the daily output ranges from 500kg to 20t. This is not a small number! You need to consider a more effective way to deal with these dung. The most common way is making your cow dung as fertilizer. But how to make cow dung fertilizer? Apart from composting, the granulating is the second important step. In fact, granulating is a fine process. If you want to produce the high quality granules, you need many steps to do.

Creating an aerobic environment for your composting. As we all know, the aerobic composting needs oxygen, temperature,and moisture. When the three conditions reach, a good composting environment is formed. In many rural areas, most farmers are used to pile their cow dung naturally. This a slow process because of the compost environment not arrives the aerobic composting. As a result, they always wait for two months at least. In fact, you can speed up the composting process as long as you use certain tools. SX is an organic fertilizer machine production manufacture, you can buy different compost turner here.

If you have own cow farm, building a cow manure fertilizer production plant can bring more benefits to you. For cow farmers, you have stable source of cow dung, thus you need a cow manure fertilizer production plant. As a professional manufacture of fertilizer making machine, we various design of the cow dung fertilizer production line. Here, we advise you the rotary drum granulator line. Due to the fiber of the cow dung, using the rotary drum granulator can reserve the fiber completely.

Our drum granulator can meet the processing capacity as small as 1t/h and as large as 30t/h. For commercial cow dung organic fertilizer production, drum granulator production is the choice of most large scale cow manure fertilizer production plant.

There is a layer of rubber lining inside the drum granulator. To prevent the cow materials sticking to the granulation drum. And the rubber is made of wear-resistant and anti-corrosion materials. It can prolong the service life of the granulator to the greatest extent.

For cow materials, the drum adopts a one-piece spiral tube, and the thickness of the plate is consistent. The entire granulation drum is supported by riding gears and their bases, which are made of wear-resistant materials due to the high-speed rotational force. Secondly, the barrel of the drum granulator is large and must be supported by a solid base. Our base uses carbon steel plate and U-steel, two types of high-temperature and wear-resistant steel.

There are many cleaning holes on the granulation drum, this design is to prevent the cow material from sticking to the wall. Because the rotary drum granulator adopts wet granulation. So hammers are installed above the outer cleaning hole of the granulation drum. With the rotation of the drum, the small hammers strike naturally to play a cleaning role.
