The granulation process of the cow manure organic fertilizer production line is a systematic engineering that converts cow manure into high-quality organic fertilizer. This process includes multiple steps such as raw material preparation, granulation, drying, screening, and packaging. The following is the granulation process and characteristics of the cow manure organic fertilizer production line:
1. Raw material preparation
As a raw material, cow manure needs to undergo pre-treatment:
Composting: Fresh cow manure needs to undergo composting treatment to kill pathogens, decompose large molecular organic matter, and improve the stability and efficiency of organic fertilizers.
Screening and crushing: After composting, cow manure needs to be screened to remove impurities such as stones, metals, etc., and then crushed into small particles suitable for granulation.
2. Granulation
Granulation is a key step in the production of organic fertilizers from cow manure, and commonly used granulation methods include disc granulation, extrusion granulation, and drum granulation.
Disc granulation: By rotating a disc, raw materials are formed into particles under centrifugal force, suitable for processing materials with certain viscosity, such as composted cow manure.
Squeezing granulation: The raw material is passed through the mold of an extruder to form particles of a specific shape, which is suitable for situations where specific shaped particles need to be formed.
Drum granulation: Raw materials are formed into particles through rotation and humidification in a drum, suitable for processing materials with high humidity and viscosity requirements.
3. Drying
After granulation, the particles need to be dried to reduce moisture content and prevent clumping or mold during storage and transportation. The commonly used drying methods include hot air drying, drum drying, etc.
4. Screening
The dried particles need to be screened by a screening machine to remove unqualified particles (too large or too small particles) to ensure the consistency and quality of the product.
5. Packaging
The qualified particles after screening are packaged by an automatic packaging machine. The common packaging form is bagged, and sealing and labeling are also required during the packaging process.
