What is the Best Humidity of Cow Dung for Organic Pellets Fertilizer Making?
The customer from UK told us that his farm had 300o cows and usually generates 20 tons per day cow dung, liquid and solid together. But excessive moisture content makes manure easier to attract parasites and is not suitable for organic granular fertilizer making. So separating solid from liquid is the first step for cow dung disposal. In this process, there are two things you must know:
Optimum Humidity for Dispose of Cow Dung into Granular Fertilizer
This client were doing this. But he asked us that what is the optimum water content for converting cow dung waste into granular fertilizer? Below 60%. Because when the moisture content of cow manure is between 45% and 60%，you can make aerobic fermentation of cow dung better. Then you can remove absolutely harmful substances from manure.
How to Separate Solid Cow Manure from Liquid Quickly
However, the humidity of fresh cow manure can even reach over 90%. How to reduce the water content of manure fast? SX design special manure dewatering machines for you. They can help you separate solid cow dung from liquid quickly and reduce the water content to 30% – 40%.

Here, it is necessary to buy suitable cow dung compost equipment, which can help you make cow dung composting within 20 days.
Which Composting Machine is Suitable for your Cow Dung?
If you only plan to start a small cow manure composting, we recommend you choose windrow composting machine. But when you need a more economical manure composter, it is advisable to buy our groove type compost turner. Is there equipment for large scale fermentation of cow dung waste? The answer is yes.

So that the products can meet the international requirements (14%) for organic fertilizer.
What is the Cost of Cow Dung Granular Fertilizer Production?
Finally, the client from UK wanted to get the quote of the system which treat cattle waste into granular organic fertilizer.
Here, it is essential to ensure capacity. During communication, the British customer told us that there are 3000 cows with 20 tons generated per day. But liquid usually accounts for 2/3 of the whole. Hence, you can only produce 6-7 tons of cattle manure compost per day. Therefore, if you make the cattle manure fertilizer manufacturing system work 2 shifts a day and 10 hours a day, you only need to buy a 2 t/h granular fertilizer making system for your cow farm treatment project. And the price of this system is $110,000-$140,000.
