What equipment is required for processing pig manure into powder and granular fertilizers

Pig manure can be processed into organic fertilizer through the organic fertilizer production line, starting from fermentation, which is the main link of harmless treatment. Through high-temperature fermentation, pathogenic bacteria and weed seeds in pig manure are killed, organic matter is humidified, and nutrients become easily absorbed by crops. The moisture content of fermented pig manure raw materials should be controlled at around 60%. Excessive or insufficient moisture can affect the fermentation effect. The fermentation method can be fermentation in a fermentation tank, tank fermentation, or stack fermentation. Customers can choose suitable fermentation equipment according to their own needs. During the fermentation process, an organic fertilizer tipping machine should be used to regularly flip the pig manure raw materials, with the aim of better oxygen absorption and more uniform and sufficient fermentation. After about 3 weeks of fermentation, the pig manure has basically matured, and then it can be stored in the tank for a few days. After a series of processes such as raw material crushing, adding auxiliary materials for stirring, and granulation, the finished pig manure organic fertilizer particles are packaged.

The first step in processing pig manure into organic fertilizer is fermentation, and the fermentation equipment is divided into the following types:

1. Organic fertilizer fermentation tank: The advantages of fermentation tanks are high environmental protection, short fermentation cycle, and small footprint.

2. Slot tipping machine: The advantage of slot tipping machine is its large processing capacity, which is suitable for large-scale organic fertilizer processing plants.

3. Crawler type tipping machine: The biggest advantage of a crawler type tipping machine is its flexible operation and does not require civil engineering.

Next, there are two situations: one is to make cow manure powder organic fertilizer, and the other is to make granular organic fertilizer.

Pig manure powder organic fertilizer equipment:

1. Feed bin: Provide raw materials evenly for the production line.

2. Crusher: Uniformly crush the fermented organic fertilizer raw materials.

3. Screening machine: After crushing, there will be some impurities in the raw materials that need to be screened out through the screening machine, and then the finished powder fertilizer will be produced.

4. Automatic packaging machine: The automatic packaging machine packages qualified powdered organic fertilizer into bags.

Pig manure granular organic fertilizer equipment:

Adding equipment on top of powdered organic fertilizer equipment

1. Organic fertilizer mixer: Powdered organic fertilizer enters the mixer to regulate water content or add auxiliary materials.

2. Organic fertilizer granulator: The stirred raw materials enter the granulator for granulation.

3. Screening machine: The produced particles may have varying sizes, and qualified particles can be screened out through the screening machine.

4. Automatic packaging machine: Qualified particles that have been screened can be packaged into bags through the packaging machine.
