From the point of view of the cattle farm, cow dung is a kind of waste. Can the cow dung be further developed and fully utilized? It has become the focus of attention. However, this problem is not difficult at present. With the emergence of various advocacy and encouragement policies for the development of the organic fertilizer industry by the country and local governments, the opportunity for large-scale and industrialized development of commercial organic fertilizer for cattle manure has matured.
How to make cow manure, chicken manure and sheep manure into organic fertilizer? What kinds of organic fertilizer equipment are needed in the organic fertilizer production line
? Let Zhengzhou Tianci Heavy Industry Technology tell you:
Step 1: Fermentation
Collect cow dung and cow urine, compose it with hay and rotten silage, and let it ferment. After fermenting, use a compost turner machine
to fully ferment the cow dung. Only in a timely and uniform manner can this be done.
Step 2: Crush and mix ingredients
Use the batching bin to comminute, mix and mix the composted materials, inorganic fertilizers such as N, P, K, and other additives through a material grinder and a horizontal mixer in a certain proportion.
Step 3: Granulation
The new organic fertilizer granulator
is used to granulate the materials.
Step 4: Screening and return system
The granules output from the granulation and molding system have a certain difference in particle size and need to be classified and classified. The selected rotary screening machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to equip with an automatic material return system to screen the unqualified large and small particles, which will be conveyed out through the belt hoist and re-smashed to the granulator to continue granulation, which will help improve the continuous operation capacity of the production line.
Step 5: Drying
An organic fertilizer dryer is used to further remove moisture from the sieved particles to meet the standard requirements for moisture content of organic fertilizer.
Step 6: Cooling
Cooling the granular materials with a cooler helps the granules to be stored and maintained.
Step 7: Packaging
The cooled granular material is conveyed into the finished product bin through the bucket elevator. Granular materials are quantitatively weighed and packed by automatic packing weighing.
