Cow Dung Manure Making Machine
Making cow dung manure is good for farming. It is also a wonderful to dispose of cow dung manure. For it is not only reduce the intolerable smell but also turn waste into money. In this page, MFP company will show you the whole set of cow dung manure making machine. This fertilizer equipment can help you make cow dung manure from scratch. What’s more, as a renowned manufacturing company, MFP can provide you high-quality machines and the best service.
Cow dung, also known as cow manure, is a good fertilizer for plants due to its rich nutrients.
Given the special digestion way of cows, there are tracks of hay, grain, straw, and organic matter in cow manure which can bring back nutrient balance to fields organically.
Why making cow dung manure is of great benefit?
One big reason is the appropriate NPK ratio in it. The ratio makes it a wonderful nutrient to the soil.
With the help of a cow dung manure making machine, you can not only make cow dung manure compost but also get better-looking cow dung fertilizer pellets.
Why do you need to complement NPK in the soil? Studies show that most of the nutrients in composts have the same effect on the soil, however, nitrogen is an exception.
First, as microbes digest, much of the nitrogen becomes available slowly. Moreover, the impact of nitrogen is contingent on the proportion of carbon to nitrogen, commonly referred to as the C: N ratio. If this ratio surpasses 30:1, then the majority of the nitrogen becomes immobilized in plants for an extended period of time. Unfinished composts that contain a high proportion of C: N ratio. During decomposition, such materials consume nitrogen from the soil, causing garden plants to be deprived of the necessary nitrogen they require for growth.
NPK ratio in cow dung manure
In general, cow dung contains approximately 3% nitrogen, 2% phosphorus, and 1% potassium—3-2-1 NPK. The appropriate ratio of cow manure makes it the right type of fertilizer for almost all types of plants and crops.
How do you make fertilizer with cow dung?
It mainly divides into two processes: composting and granulation. These processes can be achieved by compost machines and granulators. During this process, you have to take care of two factors- moisture and temperature, which will determine whether you can successfully make cow manure fertilizers or not. Hence, you need other auxiliary equipment to control the two factors, such as dehydrators and dryers. With the cow dung manure making machine mentioned above, you can get a complete cow dung manure production line and can make organic fertilizers from scratch.
Next, let’s take a look at the two processes.
How to Turn Cow Manure Into Compost?
During the composting process, bacteria will decompose the organic matter in cow manure and convert it to fertilizer. Although cow manure is a good fertilizer, fresh cow dung cannot be applied to plants. Because there is a large amount of ammonia in cow manure and it may burn the roots of plants if applied directly. If farmers apply cow manure to the soil without full decomposition, it will increase oxygen consumption. So, you must make compost with cow dung manure making machine and use fertilizer after fermentation.
Before starting to make compost, you should control its moisture at 60-70%. A higher or lower percentage of moisture will affect organic matter decomposition. MFP produces two types of cow dung dewatering machines. One is a cow dung dewatering screw press machine and the other is a solid-liquid separator machine. Their largest capacity of them can reach 40 m³ per hour.
After dewatering, you can use a cow dung manure composting machine to speed up its fermentation. We provide 3 types of machines for you.
Moving-type compost turner
Windrow type composting machines are also called self-propelled compost turners. It can save you the cost of constructing grooves. But it requires open space to make windrows. So this type of compost turner is fit for those who have expansive areas. Otherwise, it needs a worker to operate.
Groove-type compost turner
Compared with the other two types, an in-vessel composting machine is the fastest way to make compost. It is powered by electricity and can heat up to 80-100 degree Celsius. Eggs and bacteria can be killed thoroughly under high temperatures. You can process cow dung in only 10 hours. To meet your requirement, this in-vessel composting machine is customizable from 5-150m³.
This composting method is based on grooves, which means all the compost turners work in a groove.
It can flip the compost to speed up decomposition and cool the compost. On both sides of the groove installed railways.
How To Prepare Pellets From Cow Dung Compost？
To make cow dung manure fertilizer pellets, you come to the next procedure-granulation.
- First, you need to screen the fermented cow dung manure compost, and then crush it. There are beddings in it that include coarse fiber, so you need completely mix them to make sure the quality of the final products.
- You can use a pan mixer or horizontal mixer to mix the raw material with the binder(usually liquid). This procedure is to ensure the moisture to the appropriate level. In addition, you can adjust the pan or horizontal rotational speed according to the size of the desired agglomerate.
- Next, you can start manure granulation. A pan pelletizer, also known as a pan granulator, is used to make cow dung fertilizer pellets. You can control through variations in speed and incline to create a good-looking and high-quality granule. During pelleting process, you can observe the state of manure. If it is hard to agglomerate, you can spray some water to add moisture.
- Finally, before packing cow dung granules, you need to make sure their moisture is under 20%. A rotary drum dryer can dry material efficiently. Meanwhile, it can create a more uniform and quality final product.
FAQ
How long does it take for cow dung to turn in manure？
It often takes you 10-15 days to ferment with a cow dung manure compost turner, and about 7 days if you use an in-vessel composting machine.
What are the benefits of cow dung manure fertilizer?
Cow dung manure requires fairly high rates to meet first-year nitrogen requirements because of its lower nitrogen percent and gradual nitrogen release characteristics. However, this feature provides for more continued nitrogen availability in succeeding years, allowing for progressively lower annual application rates to meet plant requirements.
