The common supporting equipment for an annual 50000 tons of powdered organic fertilizer production line includes conveying equipment (such as conveyor belts and screw conveyors), microbial fermentation tanks, crushing equipment, mixing equipment, extruders, dryers, and packaging equipment. These devices can help you process and process raw materials, ultimately producing high-quality powdered organic fertilizers.

The process of an annual 50000 tons of powdered organic fertilizer production line

1、 Raw material preparation

The primary task in producing organic fertilizers is to prepare high-quality raw materials. Usually, the raw materials for organic fertilizers mainly include animal manure, crop straw, and food processing industry waste. These raw materials need to undergo pre-treatment such as collection, classification, crushing, and drying to ensure the smooth progress of subsequent processes.

2、 Mixing ingredients

Pre treated raw materials are mixed and batched in a certain proportion. The proportion of ingredients should be determined based on the type, purpose, and market demand of the fertilizer. Generally speaking, ingredients should contain an appropriate amount of nutrients such as nitrogen, phosphorus, potassium, as well as organic matter and microorganisms.

3、 Fermentation and maturation

The mixed ingredients enter the fermentation and maturation stage. This stage mainly decomposes the organic matter in the raw materials into stable organic matter and nutrients through the action of microorganisms. During the fermentation and maturation process, it is necessary to control the temperature, humidity, and ventilation conditions to ensure the activity of microorganisms and the fermentation effect.

4、 Crushing and screening

The materials that have undergone fermentation and maturation need to be crushed and screened. Crushing is the process of breaking large pieces of material into small particles for the convenience of subsequent processes. Screening is based on particle size classification to remove impurities and large blocks of material.

5、 Dry cooling

The material after crushing and screening enters the drying and cooling stage. This stage mainly aims to remove moisture from the material, reduce its moisture content, and facilitate storage and transportation. During the drying process, attention should be paid to controlling temperature and wind speed to prevent materials from overheating or clumping. Cooling is the rapid cooling of dried materials to prevent their spontaneous combustion.

6、 Crushing and sieving

The dried and cooled material needs to be crushed and sieved. Crushing is the process of further crushing materials into powder form for the convenience of users. Screening is the process of removing large blocks of material and impurities to ensure the quality of the product.

7、 Packaging and storage

After crushing and sieving, the organic fertilizer powder enters the packaging and storage stage. Packaging is generally bagged or loose, customized according to user needs. When storing, attention should be paid to moisture, sun protection, and fire prevention to ensure the quality and safety of the product.
