The organic fertilizer production line with an annual output of 20000 tons, taking poultry and livestock manure as an example, can process up to 80000 cubic meters of manure annually. Fertilizer made from cow manure and straw through high-temperature fermentation is very effective for soil improvement and promoting fertilizer absorption.
Process description of the production line for 20000 tons of cow manure straw powder organic fertilizer annually:
It mainly consists of equipment such as a stacker, crusher, mixer, granulator, dryer, cooling machine, screening machine, wrapping machine, automatic packaging machine, etc.
Working principle of an annual production line for 20000 tons of cow manure, straw, and powdered organic fertilizer:
1. Composting fermentation
The fermentation of bio organic raw materials plays a very important role in the entire organic fertilizer production process. Adequate fermentation is the foundation for producing high-quality organic fertilizers.
The organic fertilizer turner achieves complete fermentation composting and can achieve high stacking and fermentation, improving the speed of aerobic fermentation.
2. Crushing treatment
The semi wet material crusher is an efficient crusher with strong adaptability to organic raw materials with high water content. The semi wet material crusher is widely used in the production process of organic fertilizers, and has a good crushing effect on wet raw materials such as chicken manure and sludge. This crusher greatly shortens the production cycle of organic fertilizer and saves production costs.
3. Mixing treatment
After the raw materials are crushed, they are mixed with other auxiliary materials and stirred evenly before granulation. The dual axis mixer is mainly used for pre adding water and mixing powdered materials. Its spiral blades have multiple angles and can quickly and uniformly mix raw materials regardless of their shape, size, and density.
4. Screening
After cooling, there are still powdery substances in the finished product particles. All powdered materials and unqualified particles can be screened out through a drum screening machine. Then, it is transported by a belt conveyor to a mixer for mixing and granulation. Unqualified large particles need to be crushed before granulation. The semi-finished products are transported to the organic fertilizer coating machine.
5. Packaging
This is the final production process. The fully automatic quantitative packaging machine is an automated packaging machine designed and manufactured specifically for particles of different shapes. The weighing control system meets the requirements of dust and water prevention, and the material box can also be configured according to customer requirements. Suitable for batch packaging of bulk materials, it can automatically weigh, transport, and seal bags.
