Last Sunday, an organic fertilizer powder production line was shipped to Paraguay.

The organic fertilizer powder production line is mainly used to produce powdered organic fertilizer. Its core equipment and work process are different from those of the granular production line (granulation, drying and other links are usually omitted).

The following is a detailed introduction to the equipment composition and work process:

一、 Main equipment components of organic fertilizer powder line

1. Pretreatment equipment

Crusher: used to crush large pieces of raw materials (such as straw, livestock and poultry manure, etc.) to ensure uniform raw materials.

Mixer: Mix different raw materials (manure, straw, bacterial agents, etc.) in proportion to improve fermentation efficiency.

2. Fermentation equipment

Compost turner/trough turner: Promote aerobic fermentation and accelerate decomposition by regularly turning the materials.

Fermentation tank/fermentation pool: Provide a controllable fermentation environment (temperature, humidity, ventilation).

3. Crushing and screening equipment

Semi-wet material crusher: Finely crush the fermented materials to avoid agglomeration.

Drum screen/vibrating screen: Screen out large particles or impurities that are not fully decomposed to ensure that the fineness of the finished product meets the standard.

4. Packaging equipment

Automatic packaging machine: quantitative weighing, bagging, sealing, improving packaging efficiency.

Conveyor: connecting equipment in each link to realize automatic material flow.

5. Auxiliary equipment

Deodorization system: to deal with odorous gases such as ammonia and hydrogen sulfide generated during the fermentation process.

Dust collector: to control dust pollution in the crushing and screening links.

二、 Organic fertilizer powder line workflow

1. Raw material pretreatment

Crushing: The raw materials are crushed by a crusher to a particle size of ≤5cm.

Mixing: Mix manure and auxiliary materials (such as straw, bacterial agent) at a carbon-nitrogen ratio (C/N) of 25~30:1.

2. Aerobic fermentation

Stacking fermentation: Stack the mixture into strips, turn it regularly (once every 2~3 days) through a compost turner, control the temperature at 55~70℃ for 15~30 days, and kill pathogens and weed seeds.

Determination of maturity: The material is dark brown, odorless, and loose, which means it is mature.

3. Crushing and screening

Fine crushing: The decomposed materials are crushed to 80~100 mesh by a semi-wet material crusher.

Screening: The coarse particles that do not meet the standards are removed by a vibrating screen (they can be returned for re-crushing).

4. Finished product packaging

Measuring and bagging: The powder is packaged in a quantitative manner (such as 25kg/bag) by an automatic packaging machine and transported to the warehouse for storage.

三、Key equipment features

1. Compost turner

Type: crawler/trough type, suitable for different fermentation scales.

Function: turning the compost and aerating at the same time, accelerating water evaporation and organic matter decomposition.

2. Semi-wet material crusher

Advantages: suitable for materials with moisture content ≤30%, anti-stick knife design to avoid clogging.

3. Automatic packaging machine

Accuracy: weighing error ≤0.2%, supporting various packaging forms such as woven bags and film bags.
