As a major cattle-raising country, how does the United States solve the livestock and poultry manure pollution? The U.S. government has implemented a comprehensive nutrient management plan ( CNMP) for livestock and poultry manure. One of the most commonly used measures is to turn cow dung into organic fertilizer. Here, YUSHUNXIN can offer you best plan and equipment for the cattle manure management. For example, we designed a 2 t/h system to make granulated cow manure for our American customer, who inquired on 6th February 2024.
Granulated Cow Manure Making
The following are the specific details of communication in this case
What are the United States customer’s requirements of cow manure disposal?
How to dry cow manure to 88% – 90% total solids?
Firstly, how to dry cow manure? For this, we recommend you divide the manure drying into two processes:
Hot air dryer of dewatered dairy waste
For dairy cow waste drying, hot air cow manure rotary dryer is necessary. It can reduce the moisture of cow dung to lower than 10%. Namely, the output dried cow manure and fertilizer is at over 90% solid. The machine makes use of over 300 ℃ hot air to evaporate the excessive water from cow manure organic fertilizer in a short time.
Cow manure dewatering
But, for the rotary dryer, it is advisable to process cow dung with below 60% moisture (higher than 40% solids ). Because the higher the manure moisture, the longer the drying time and the more the energy consumption. For this, add a cattle litter dewatering machine before hot air dryer is an ideal choice for you. Mainly makes use of physical press force to remove excessive water from cow manure slurry. So you can greatly reduce the cost of cow manure drying.
After cow manure dewatering, the moisture can decrease to 30%. Then the rotary drying machine can produce dairy cow manure fertilizer granule with 88%-90% total solids fast and economical.
Which machine can make uniform granulated cow manure without compress?
In addition, the American client another requirement of cow waste management is preparing uniform granulated cow manure fertilizer. However, The customer wished the end product will be not “granules” that are compressed. In other words, the cow manure fertilizer pellets will hold its uniform shape, but can be crumbled in your hand.
Here, we can offer you disc granulator and rotary drum pelletizer. With the disc and the drum rotating, the cow dung material will move upward; then under the action of gravity, the small particles will roll down and combine with other materials to form into granulated cow manure fertilizer you need. What’s more, the final cow dung organic fertilizer granule is in rounded shape. And, without pressing, the final cow dung fertilizer pellets can fully meet the needs from the United States client.
