Cow dung management.
It is a headache to mention the cow dung of the farm. It not only pollutes the environment, but also seriously affects the living environment of the residents. In fact, cow dung contains a lot of nutrients needed for crop growth. It is an ideal project to make cow manure into organic fertilizer by adding biological bacteria. The output of a cow manure is about 40 kg per day. It is very suitable to build a small organic fertilizer production line for a 500 head cattle farm.
How to deal with the cow dung in the cattle farm and the technological principle of the cow manure treatment in the cattle farm.
Fermentation.
The cow dung is collected, mixed with hay and rotten silage to make compost. Biological bacteria are added into the compost to make it ferment. In the fermentation process, the tipper is used to fully ferment the cow dung. The tank tipper is very suitable for the early fermentation of cow manure, and the fermentation is uniform.
The ingredients are crushed and mixed.
The composted materials, inorganic fertilizers such as N, P, K, and other additives are crushed, proportioned and mixed by material crusher and horizontal pulverizer according to a certain proportion.
A new type organic fertilizer granulator is used for granulation.
In order to get cow dung fertilizer pellets, you can use this new type organic fertilizer granulator. It can help you to get organic fertilizer granules from cow manure. (how to get dairy manure fertilizer?)
Fertilizer screening process.
The screening and return system of the granulator output from the granulation molding system has a certain difference in material diameter, which requires screening and classification. The selected rotary screen requires small vibration, low noise, convenient screen change, and is equipped with screen surface cleaning device. It is recommended to equip with an automatic return system to screen unqualified particles, which are transported by belt elevator, crushed again and sent to the granulator Granulation is helpful to improve the continuous operation capacity of the production line.
Cow dung fertilizer drying and cooling.
The organic fertilizer dryer is used to further remove moisture from the screened particles to meet the standard requirements of moisture content of organic fertilizer. The cooling machine is used to cool the granular materials, which is helpful for the storage and quality assurance of particles.
Fertilizer packing.
After being packaged and cooled, the granular materials are transported to the finished product warehouse by the Gladiator elevator, and the granular materials are quantitatively weighed and packaged by the automatic packing scale.
