Method and supporting equipment for producing organic fertilizers from cow manure

Method and supporting equipment for producing organic fertilizers from cow manure:

Step 1: Tank fermentation equipment

Collect cow manure and urine, mix them with hay and rotting silage to make compost and let it ferment. During the fermentation process, a composting machine is used to fully ferment the cow manure. Only timely and uniform composting can achieve this. Some places are very dry now, while others are very wet, which can affect the fermentation quality.

Step 2: Material crushing equipment

Semi wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. Utilizing high-speed rotating blades to crush fibers with good particle size and high efficiency. Semi wet material crushers are mostly used in the production and processing of organic fertilizers, and have good results in crushing raw materials such as chicken manure and humic acid sodium.

Step 3: Mixing and mixing equipment

The mixer has fast mixing speed and good uniformity, and can mix viscous materials with 30% added liquid. During operation, there are two opposite rotating blades and rotors stirring in the middle. Due to the multiple special angles of the blades, regardless of the shape of the material. What is the size and density. Can mix quickly and effectively. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Equipment for producing organic fertilizer pellets from cow manure

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. We suggest using a new type of organic fertilizer stirring tooth granulator

Step 5: Drum drying equipment

Using an organic fertilizer dryer, further remove moisture from the granulated particles to meet the standard requirements for organic fertilizer moisture content.

Step 6: Drum cooling equipment

Cooling the dried granular material with a cooling machine helps to preserve the quality of the particles.

Step 7: Screening and return system

The particle material output from the granulation and forming system has certain differences in particle size and needs to be screened and graded. The selected rotary screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

It is recommended to equip an automatic return system to screen unqualified large and small particle materials, transport them out through a belt elevator, re crush them, and then send them to a granulator for further granulation, which helps to improve the continuous operation capacity of the production line.

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 or liquid coating technology. It can effectively prevent the caking of composite fertilizers. The host is equipped with a polypropylene lining 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.

Conveyor: The link of the organic fertilizer production line can be configured with belt conveyor, bucket elevator, or screw conveyor according to the actual needs of customers.
