Process steps for producing granular organic fertilizer from cow manure

 The organic fertilizer production line is a series of equipment and processes that convert organic fertilizers into organic fertilizers. It is a very important part of the agricultural production process and can help farmers use fertilizers more efficiently to improve the growth rate and yield of crops. The complete fertilizer equipment includes the following main equipment.


Process steps for producing granular organic fertilizer from cow manure

Step 1: Fermentation and maturation

Collect cow manure and urine, mix them with straw, hay, and other materials to control the moisture content by about 65%. Stack the materials into long strips with a width of 2-5 meters or more, sprinkle 1KG of aerobic fermentation bacteria with 2-3 cubic meters, mix thoroughly with a wheeled composting machine, and let them ferment. After fermentation, use a composting machine to cool the materials.

Step 2: Material crushing

Crush the fermented and matured organic raw materials. Organic fertilizer wet material crusher is a professional crushing equipment for high humidity, multi fiber substances. By using high-speed rotating chains, the particle size of the crushed fibers is good.

Step 3: Mixing and stirring

Add trace elements, excipients, humic acid, clay, etc. and mix and stir. Using a vertical mixer, the mixing speed is fast and the uniformity is good. It can mix viscous materials with an added liquid of 30%. During operation, there are two opposite rotating blade rotors stirred in the middle. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Forming granulation

The material is granulated using a disc granulator, an organic fertilizer stirring tooth granulator, or a new type of stirring tooth rotating strand three combination granulator.

Step 5: Drum drying

The organic fertilizer dryer further removes moisture from the granulated particles to meet the standard requirements for organic fertilizer moisture content.

Step 6: Drum cooling

Cooling the dried particle material with a cooling machine helps to preserve the quality of the particle storage.

Step 7: Screening and return system

Due to the difference in particle size of the granular material output by the granulation and forming system, it needs to be screened and graded. The selected drum type screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

Step 8: Particle coating equipment

The coating machine is composed of a screw conveyor, a mixing tank, an oil pump, a main engine, etc., and is used for powder flapping or liquid coating technology. It can effectively prevent fertilizer from clumping, and the host is lined with polypropylene or acid resistant stainless steel.

Step 9: Packaging equipment

Granular materials are packaged and transported through conveying equipment into the finished product warehouse. Granular materials are quantitatively weighed and packaged through automatic packaging scales.

  There is a huge demand for bio organic fertilizers in China, especially for some economically efficient and high-quality bio organic fertilizers, which are more popular among farmers. Therefore, opening an organic fertilizer equipment processing fertilizer factory can yield substantial returns. Organic fertilizer trading market. The production of green fruits and vegetables cannot be separated from organic fertilizers. A large amount of organic fertilizer is piled up and wasted in urban areas, and there is a huge demand gap for organic fertilizer in rural areas. If a rural organic fertilizer trading market is established, a bridge between supply and demand can be established, and the production of organic fertilizer through processing of bio   organic fertilizer equipment   can turn waste into treasure. How much does the entire set of equipment for processing bio organic fertilizers cost? 1. Determine the size of  organic fertilizer equipment , such as the annual p...

  Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of  organic fertilizer production equipment  and the relevant situation of organic fertilizer fermentation equipment. Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful. 1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer ...
