How to Choose Suitable Equipment for Organic Fertilizer Production Line

fertilizer granulator Oct 16, 2023

In order to ensure that the base fertilizer can adequately supply the nutrients for the growth of vegetables throughout the growth period, the method of mixing organic fertilizers with chemical fertilizers is often used in the base fertilizers. Usually, 100% of the required phosphorus fertilizer, 20%-50% of the potassium fertilizer, and 30%-50% of the nitrogen fertilizer are mixed into the organic fertilizer and applied together. The amount of chemical fertilizer should be adjusted according to the quality and quantity of the organic fertilizer used. On the one hand, adding biological bacterial fertilizer to the base fertilizer can better improve the soil and improve the absorption and utilization rate of nutrients; on the other hand, biological bacterial fertilizer can prevent root diseases and continuous cropping damage by bacteriostasis.

If you want to choose a suitable organic fertilizer production line equipment list, you must consider whether you are producing powdered organic fertilizer or granular organic fertilizer, what are the raw materials for producing organic fertilizer, what are the process standards you want to achieve, and the product requirements must be determined. There are many varieties of organic fertilizers, organic-inorganic compound fertilizers, bio-organic fertilizers, granular organic fertilizers and powdered organic fertilizers circulating in the market. Different products correspond to the needs of different production line equipment. The production of granular organic fertilizers also requires a disc granulator machine. Small-scale organic fertilizer production lines can be used for the production of ordinary organic fertilizers such as granulation equipment. After determining these problems, you can get an accurate list of organic fertilizer equipment.

The annual output of 10,000 tons of organic fertilizer production line equipment basically includes organic fertilizer fermentation turner, pulverizer, mixer, npk fertilizer granulator, dryer, cooler, screening machine, automatic packaging machine, belt conveyor, etc. The fertilizer granulator machine price is also different. The price of the whole set of organic fertilizer production equipment is about 200,000-300,000, which is the configuration of the granular organic fertilizer production line. If a powdered organic fertilizer is produced, the equipment is simpler and the price is lower.

Process flow of a 30000 ton annual production line of powdered organic fertilizer

fertilizer granulator Oct 16, 2023

Introduction to the  30000 tons of powdered organic fertilizer production process per year:

1. Ratio of raw materials per ton: 500kg of cow manure+300kg of pig manure+200kg of bacterial residue+50g of bacterial species (cow manure and pig manure can also be replaced by other animal manure). Auxiliary materials: When the humidity of animal manure is high, appropriate materials with low moisture content such as straw, rice husk, and cake can be added to reduce the moisture content of the fermentation material.

2. Stacking: According to the above raw material ratio, stack as needed. The length of the pile is unlimited, with a width of 2 meters and a height of about 1 meter. When stacking materials, it is necessary to stack them evenly layer by layer. Select the appropriate width of the tipping machine based on the amount of fecal treatment each time. The following figure shows a slot type tipping machine with lifting mechanism, which can adjust the stacking height and shorten the stacking return speed.

3. Add strain: Expand the strain and residue in a 1:5 ratio (the purpose of this is to dilute the strain and spread it evenly. For example, using 1kg of strain with 5kg of wheat bran or rice husk powder is acceptable). Generally, 1kg of bacterial strains can ferment 10-20 tons of feces and straw. In cases of high fermentation capacity, a dual shaft horizontal mixer can be used to evenly mix and sprinkle on the surface of the pile according to the number of piles.

4. Flipping fermentation: Use a slot type tipping machine to flip and toss the strip pile. When the temperature rises to above 55 ℃, the pile should be flipped every 1-2 days. After 10-15 days of fermentation at 55 ℃, the pile should be folded up. (The purpose of flipping the pile is to evaporate water, allow oxygen to enter the inside of the pile, and allow bacteria to quickly reproduce and ferment inside the pile)

5. Crushing: Fermented materials cannot be directly sold as commodities because long-term stacking can cause agglomeration and other phenomena. At this point, the remaining large pieces of material need to be finely crushed by a high humidity material crusher to obtain powdered organic fertilizer. (In the early stage of fermentation, in order to accelerate the fermentation process, auxiliary materials can be added to a grinder for crushing)

6. Screening: In order to improve sales performance, the powdered organic fertilizer is re screened to obtain uniform and consistent powdered materials before packaging. After following the above steps, the pure powdered organic fertilizer is sieved by a drum screening machine.

7. Packaging: The powdered organic fertilizer can be directly stored and sold after being packaged by an automatic packaging scale.

After these 7 steps, the powdered organic fertilizer can be produced. Of course, if making standard powdered organic fertilizer, it is necessary to measure the organic matter composition of fermented manure and straw fertilizer, add nitrogen, phosphorus, and potassium content, and adjust the proportion of straw and other auxiliary materials to determine the various content formulas of organic fertilizer.

Organic fertilizer equipment processes waste into fertilizer to achieve resource utilization

fertilizer granulator Oct 16, 2023

Highly fertile soil has a strong regulating effect on soil water, fertilizer, air and heat, and provides continuous and stable nutrients. Due to the active activity of soil microorganisms and enzymes, the quality and taste of agricultural products are significantly improved, and the fresh-keeping period of stored vegetables and fruits is prolonged. Through the recycling mode of “agricultural waste-biological-organic fertilizer-plant”, it has become a bridge between agricultural waste and crops, opening up a road of sustainable development, with unique advantages.

For example, pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus and 0.35-0.45% potassium. Pig manure has a complex structure, including proteins, fats, organic acids, cellulose, hemicellulose and inorganic salts. It contains more nitrogen, so the carbon to nitrogen ratio is low, about 14:1. Under normal circumstances, it is easily decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops.

The organic fertilizer production process is as follows: the organic fertilizer raw materials (livestock manure, domestic waste, litter, biogas residue, waste bacteria, etc.) are fermented and pulverized with a semi-wet material pulverizer, and then nitrogen, phosphorus and potassium elements are added until the mineral elements reach Standard requirements, then mix with a mixer, enter the granulator (npk fertilizer granulator, drum granulation, disc granulator machine, new organic fertilizer granulator, etc.), then dry and sieve, qualified products are packaged, not The qualified products are returned to the organic fertilizer granulator machine after being ground.

The investment scale and product selection plan of organic fertilizer equipment should fully consider the characteristics of raw materials, local soil conditions, regional crop structure, main crops, local resources and market potential, market coverage radius, and the price of organic fertilizer equipment such as fertilizer granulator machine price. Generally speaking, the annual output of new small factories is 10,000 tons (1.5-2.5 tons/hour), 20,000 tons (2.5-3.5 tons/hour), and 30,000 tons (4.5-6 tons/hour).
