20000 Ton Per Year 380V 100KW Fertilizer Manufacturing Plant

annual output of 20,000 tons of organic fertilizer production line plan

The basic process of organic fertilizer production line is briefly described as follows:

1. Fermentation process section (1) Pre-fermentation uses 20 tons of cow dung, 10 tons of chicken dung and 20 tons of pig dung as raw materials and is added into the mixed pre-fermentation device (imported from Holland), carry out organic material inoculation, full mixing and pre-fermentation.

The main fermentation adopts triple-combined horizontal anaerobic fermentation equipment (patent equipment), adding biological strains, the fermentation temperature is controlled between 50-60 ℃, and the color is dark brown after the fermentation is completed, no feces smell but composting smell. After the biogas is collected, it enters the biogas boiler through the water-sealed tank and flame arrester to burn, providing heat for the fermentation unit, granulation, drying and other units.

2. Compound process section of organic fertilizer production line (1) pulverize the ingredients (straw, straw, bean cake, bone meal, hoof horn powder, etc.), and pulverize the inorganic fertilizer at the same time.

2.1 compounding and mixing of raw materials the formula of organic and inorganic raw materials is mixed according to different series of products. It is fully mixed in the mixer. If the proportion is 12%, it is about 12 tons.

2.2 Control of moisture content adding straw powder or organic materials with lower C/N ratio of charcoal than high moisture content, the addition amount is 6 tons of charcoal per day, 6 tons of grass carbon per day, 18 tons of straw and wheat straw per day, the moisture content of the treated raw materials is 60%-65%, and the C/N ratio is 20-30. The added substance must be fully broken.

3. Granulation process of organic fertilizer production line (1) pulverize, ferment, store for 1 day, and crush. Dry, crush and screen the fermented organic materials.

3.1 compound and mix in the process of making series of special fertilizers, inorganic nutrients and minerals with concentrated organic matter and trace elements are added according to different soil conditions and crops, make the fertilizer contain a variety of nutrients needed for plant growth, such as nitrogen, phosphorus, potassium, sodium, manganese, zinc, copper, etc. According to the formula, nitrogen, phosphorus, potassium and fermented materials are mixed by computer, and transported to the granulator for granulation. The formula of organic and inorganic raw materials is mixed according to different series of products. Fully mix in the blender. If the proportion is 12%, about 12 tons.

3.2 granulation due to the production of biological fertilizer, organic matter is the main factor, cellulose is abundant, forming conditions are poor, and live bacterial groups with fertilizer-making function are added, and the production process is not suitable for exposure to high temperature, etc. The method of making materials should not adopt the methods of pelleting and rotary drum, because these two processes require high crushing fineness of raw materials, high granulation moisture content, and the general moisture content should reach about 30%, for this reason, the drying load is large, the loss of effective bacteria is also large, and the ball formation rate is low (about 60% ~ 70%), the dust is large in the production process, and the operating environment is very poor, therefore, for the production of organic biological fertilizer, it should be produced by environmental extrusion method. Environmental extrusion has low requirements on raw material crushing, high molding rate (above 95%), and low water content of particles after forming, the drying load is very small, which can reduce the loss of effective bacteria, with small dust and good operating environment.
