Why composting is the first step to convert cow dung into organic fertilizer?
If you want to process cow dung into organic fertilizer, composting is the first step. Without composting, you cannot use cow manure directly as fertilizer for the plants. Why? there are two reasons:
Fresh cow dung contains many harmful substances
Usually, fresh cow dung in the farm is the source of many kinds of bacterial pathogens. And it contains parasite eggs and disease-causing microbes. If you leave cattle manure alone on the farm, it will generate malodor to produce effects on breeding communities. In addition, if you use it directly as fertilizer for the plants. The fresh cow manure will compost naturally and produce lots of heat to burn the roots and seedlings. So, fresh cow manure is not truly organic fertilizer products.
Composting makes cattle waste harmless
But the composted cow dung is different. During the process of cow manure composting, the high heat will be generated and kill harmful bacteria, pest eggs and grass weeds. Moreover, after composting, the cattle droppings no longer stink and generate heat during use. So you don’t worry that it will burn plant roots. But it takes a long time to make the cow dung to decompose and ferment naturally, about 2-3 months. So you need some fertilizer composting machines to shorten this time. Only about 20 days.
What equipment can be used in cow manure composting？
When you want to start cow waste composting, you will find that there are many types of composting machine on the market. Then which is the most suitable one for you? In general, these fertilizer composters can be divided into three parts. Trench working compost turner, windrow compost turner and in-vessel fermentation tank. You can choose according to your needs.
Trench working compost turner for sale
Groove composting (or trench composting) is widely used in cattle breeding farms management. Using this method, you can compost cow waste in an easier way without waiting for natural decomposition. But only collecting cow manure and stacking them together in the trench is not groove composting. You need to turn the raw materials to make them fully fermented. For this, we recommend you to choose wheel type compost turner or groove type compost turner.
Windrow compost turner
If you don’t want to spend money on groove building, you can choose windrow compost turner, which can compost cow manure on the ground. Windrow composting is a good way for cattle farmers to make organic cow dung compost in their own farm. By paving the raw materials in long windrows and equipping a windrow compost turner, you will get organic cow manure compost within 20 days. If you’re afraid that rain will affect the quality of your compost, you can build a greenhouse to protect the windrows. In this case, SX can offer you crawler type compost turner and moving type compost turner for windrow composting.
In-vessel fermentation tank
If you are desirous of composting cow manure in an environmentally friendly way or don’t have enough space for open fermentation. In-vessel fermentation tank is your best choice. Only 10-30㎡, it can help you finish cow dung fermentation within 20 days. And it is equipped with waste gas treatment system, so there is no secondary pollution in the process of cattle waste composting. In SX, there are two types of in-vessel fermentation tank for your choice. Horizontal fermentation tank and vertical fermentation pot. The former is more suitable for compost cow litter with a volume less than 20㎡, the latter is an optimal choice for larger amounts of cattle manure fermentation.

If you want to improve the quality of your cow manure fertilizer, making it into granules is an excellent choice for you. After granulation, the contact area between cow dung fertilizer and air will become smaller, so it is not easy to absorb moisture and agglomerate. Therefore, it is more convenient for transport and storage. In addition, the granular fertilizer is less likely to be blown away by the wind, so the utilization rate of your cow manure fertilizer is higher. There are various granulating machines in SX for your choice. Among them, disc granulator and rotary drum pelletizer are popular with cow dung fertilizer manufacturers.

So it is suitable for you, if your ideal annual output is below 40,000 tons. And another reason why the pan pelletizer is so popular is that it has a high granulating rate. The granulating rate of pan granulator can reach 93%. It means you can get more fertilizer pellets with the same amount of materials. Moreover, the pan granulation machie is also an ecnomical option for you. It is made of high quality alloy steel, which has a high performance in corrosion resistence.
