How to make cow manure into quality organic fertilizer?


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.

Wheel type compost turner is suitable for starting a large scale fermentation of cow manure with low cost. Because its turning width can reach 10-30m, and turning depth can reach 2m. So you don’t need to build too many trenches and reduce the cost on infrastructure projects. In addition, the double-wheel design can help you compost more quickly. And hydraulic lift design allows you to easily raise the wheel and quickly return the compost turner to the starting point to change slot. These operations can be remotely controlled, so you will spend less on the labor force.
If your budget on fertilizer composting equipment is not enough, you can choose groove type compost turner. It is suitable for the trench with a width of 3-6m. If you want to enlarge the fermentation scale of cow manure fertilizer, you only need to increase the number of grooves. We can provide you with the transfer vehicle to realize the multi-groove working.  In the process of cow dung composting, it can keep the temperature of the materials between 65℃-70℃, the optimal temperature for fertilizer fermentation. So you can ferment and decompose the cow dung quickly.

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.

When you want to buy an easier operated windrow compost turner for cow manure processing, we will recommend you crawler type composter. It doesn’t require the steering wheel, the driver simply controls two bars, then the machine can turn left or right, brake and 180 degrees turn around. And it adopts hydraulic balance technology, which make it can automatically raise and lower the height of compost turner shaft. So it can compost fertilizer piles at high speed according to the moisture degree of the material. In addition, it is equipped with soft start turning clutch, which can reduce the damage to chain, bearings and shaft. And front hydraulic push plate design can greatly save the space, time, diesel, manpower and shorten the cattle litter fermentation period.
But if you need a more flexible windrow compost turning machine, you can buy moving type compost turner. It adopts four wheel walking design, which can move forward, backward and turn freely. And it only needs one worker to operate. During the cow manure fermentation process, the machine rides astride above the pre-piled strip fertilizer bases. Then the rotary blades mounted on the shaft will mix, fluffy and move the strip fertilizer bases along with the movement of the moving type compost turner. So that makes the fertilizer bases forming into new strip stacks. This can effectively and evenly mix the viscous cow manure with straw powder and other materials, so that creates a better aerobic environment for cow dung fermentation.

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.

How to choose right equipment for making cow dung compost into granules?

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.

Disc granulator machine for small scale cow dung fertilizer granulation

If you need a granulator to make fertilizer from cattle litter in a small scale, the pan granulating machine is an excellent choice for you. It can produce 1-6 tons of fertilizer per hour. 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. And compared with other pelletizers for cow dung processing, it has a more favourable price. Therefore, if you want to turn cattle litter into granules at a low cost, we commend you choose it.
