How to utilize cow dung in the cattle farm?
Cow dung, from the point of view of the cattle farm, is a waste. Can cow dung be redeveloped and fully utilized? It has become the focus of attention. However, this issue is no longer a difficult point. With the introduction of various advocacy and incentive policies for the development of organic fertilizer industry by local governments, the time for large-scale and industrialized development of cow manure commercial organic fertilizer has matured.
Way to make fertilizer
It was found that dried cow dung can be used as organic fertilizer after fermentation. It can shake off soil, improve soil compaction, cut trace elements in soil and improve soil fertility. The production of cow manure organic fertilizer is not through the production process of NPK fertilizer.
Cow dung is a good fertilizer to produce organic fertilizer. Dried cow dung contains 10% – 20% crude protein, 1% – 3% crude fat, 20% – 30% nitrogen-free extract and 15% – 30% crude fiber, so it has high nutritional content.
How to make fertilizer from cow dung?
How to turn cow manure, chicken manure and sheep manure into organic fertilizer? What fertilizer manufacturing equipment is needed for small-scale cattle manure organic fertilizer production line? In the fertilizer production line, the following steps are essential.
Step 1 cow manure fermentation
Cow dung and urine are collected and mixed with hay and rotten silage to control the moisture content of the organic fertilizer raw material, so that the compost can be composted and fermented. In the fermentation process, the dumper is used for the full fermentation of cow dung, only in time or even dumping can achieve the purpose. Now some places are very dry, some places are very wet, which will affect the quality of fermentation.
Step 2: mixed with other ingredients for quality fertilizer production
Compost and fermentation materials are crushed, proportioned and mixed in a batch tank through an organic fertilizer grinder and a horizontal mixer.
Step 3: machines for cow dung fertilizer granulation
The material is made of drums.
Step 4: How to screen unqualified cow dung fertilizer pellets out?
The particles in granulation system have different particle sizes, which need to be screened and classified. The selected rotary screen needs low vibration, low noise and convenient screen replacement, and is equipped with screen surface cleaning device.
It is suggested that an automatic reflux system should be equipped to screen out the unqualified large and small particles, which will be transported through the belt elevator and sent to the granulator to continue granulation after being crushed again, which will help to improve the continuous operation capacity of the production line.
Step 5: machines to dry cow dung pellets
The organic fertilizer dryer is used to further remove the moisture in the sieved particles to meet the standard requirements for the moisture content of organic fertilizer.
Step 6: Get dried cow dung pellets for bagging
A cooler is used to cool the granular material, which facilitates the storage and quality of the particles.
Step 7: packaging cooled fertilizer for sale
The cooled granular material is transported to the finished product warehouse by bucket elevator. Granular materials can be weighed and packed quantitatively by automatic packing scale.ow
