In chemical processing industry, rotary drum granulator is widely used in organic fertilizer production line and NPK fertilizer production line. In the granulation process of the drum granulator, the coarsening in the pellet is mainly in the form of cladding, so the material circulation volume should be larger, so as to provide a coarser core for the cladding process, and the water injection volume should be smaller, so as to reduce the water absorption of the core.
When pelletizing by bonding or “gathering”, the materials are smaller, because the materials in the drum are mainly composed of fresh materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the space between the fine powder particles to be bonded with each other should be filled with water.
The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in incomplete fermentation of materials or long fermentation time. If the material fermentation is well formulated, the effect is better than inorganic fertilizer, and the cost is also low. It can also improve the living environment of plants and become green fertilizer. The formula of organic-inorganic compound fertilizer is different from that of inorganic fertilizer, and there are also differences in different soil and crop formulas. The organic fertilizer manufacturing process is different from that of compound fertilizer, and the fertilizer production machine is also different.
Difference of production technology between compound fertilizer and organic fertilizer
The machines required for the organic fertilizer manufacturing process is mainly divided into two parts, fermentation part and production granulation part. NPK fertilizer manufacturing process is mainly granulation processing. The granulation part of organic fertilizer is also different from that of inorganic fertilizer.
Because organic raw materials are different from inorganic raw materials, the production of inorganic raw materials can be mainly based on the formula of raw materials, which is mainly chemical reaction. If the formula is proper, the operation is skilled, the pelletizing rate is very high, and the production is relatively easy. Roller granulator is suitable for dry granulation of NPK fertilizer and disk granulator is suitable for wet granulation.
For organic fertilizer, granulation is difficult even if the raw materials are fermented well, because the characteristics of organic raw materials are light, rough, low adhesion, and a wide variety of organic raw materials. Raw materials have different characteristics, so when selecting fertilizer granulating machine, special attention should be paid, otherwise not only the output will be affected, but also the appearance of the product is not beautiful. Rotary drum granulator is generally used for granulation of organic fertilizer and compound fertilizer.
fertilizer production machine
When selecting the organic fertilizer production machine, we should pay attention to the following points: output of organic fertilizer production, organic raw materials, fermentation mode, fertilizer granulator machine, mechanization degree of organic fertilizer equipment. These are key factors in purchasing equipment. In short, organic fertilizer production is a relatively complex process, but the risk is relatively small, which can bring rich profits to the enterprise.
Furfural residue is a kind of waste after extracting furfural from corn cob, oat and wheat bran, sawdust and other agricultural by-products. It also contains more lignin, semi lignin, cellulose and other organic components. These wastes can be transformed into organic fertilizer for plant growth by using organic fertilizer production equipment. Compared with other fermented organic fertilizer materials, furfural organic fertilizer also has the characteristics of low cost. It is a rare raw material with low cost and high cost performance.
1. Fermentation of furfural residue organic fertilizer must adjust PH value
Before the furfural residue is subjected to biological fermentation treatment, we recommend measuring the pH of the furfural residue. The furfural slag left after most industrial processes is highly acidic, with a PH value between 3-4, while the PH value suitable for the rapid reproduction of microorganisms is generally between 5-8. Therefore, it is recommended to use lime water to adjust the pH to about 6-8.

2. Oxygen-consuming fermentation
Furfural residue fermented organic fertilizer is a kind of biological product obtained by aerobic and temperature-fermentation fermentation of organic substances by microbial beneficial bacteria. Microorganisms will generate temperature when they decompose the organic matter in the material. These temperatures will kill most pathogenic microorganisms at 65-70°C. At this time, there are certain requirements for the composting of the material. If the stacks are stacked, the stack body is too small, and the temperature is difficult to increase; the stack body is too large, which will increase the difficulty of material tossing. According to the experience of fertilizer granulator manufacturers, it is recommended that the height of the compost be less than 1.5 meters, the width of the pile be about 2 meters, and the water content be adjusted to 60%, and then fermentation. If there is a fermentation tank, just put the furfural residue in it.
3. Temperature measurement and turning during fermentation
After stacking the materials, it is recommended to cover a layer of plastic cloth with holes on the outside of the pile to keep the heat and also to pass oxygen. However, these oxygen are far from enough. During fermentation, it is necessary to measure the temperature of the fermentation pile. When the temperature exceeds 50 ℃, the compost turning equipment shall be used to stir the materials and aerate them. After fermentation, it is suggested to mix the compost with other nutrients and make organic compound fertilizer products by disc granulator.
The potassium fertilizer is fed into the disc granulator, so that the material gradually piles up by itself until it reaches the required particle size. When the raw materials are piled up on the disc, the binder can be added to support the agglomeration of the materials. Since water will be added to the disc during granulation, additional drying process is required for the fertilizer production line when using this method of rolling raw materials into balls.
Advantages and disadvantages of potash fertilizer granulation
1. The granulation of potash fertilizer has many advantages. This non pressure agglomeration technology can produce particles with smaller density, so that the particles can decompose rapidly. Because most of the potash fertilizer can be used as fertilizer after processing, the ability to decompose and provide nutrition faster is the inducement to choose potash fertilizer particles. It is an ideal product for fertilizer compounds with fixed formula requirements that require rapid nutrient delivery. The round granular potash fertilizer is also easy to handle, and the fineness of potash fertilizer is lower than that of compacted particles.
2. The main disadvantage of potash granulation is that the processing cost is high, and potash particles are considered as high-quality products. Therefore, it is not generally produced like compacted particles. However, it is worth mentioning that the disc granulator is the ideal choice (as opposed to the fertilizer extrusion production process) due to the hardness of potassium salt in the treatment of some potassium salt derivatives.

Granulation technology of potash fertilizer
Disc granulator machine is widely used in the field of potash fertilizer granulation, NPK fertilizer granulator can also be used in the processing of potash fertilizer and a variety of compound fertilizers. The disk type fertilizer granulator is a new type of fertilizer granulator: its granulation rate can reach more than 95%, the main gear of the granulator is quenched with high frequency, the service life is doubled, the disk of the disc pan granulator is of arc structure, lined with high-strength fiberglass, and the bottom of the disk is strengthened by a number of radiation steel plates; it is durable and never deformed. After the potassium fertilizer powder enters into the pelletizing plate, the material continuously rotates and is sprayed by the pelletizing plate, so that the materials stick together to form spherical particles.
Oil palm is a very cold resistant tree, which is a crop with good economic value and widely planted in some areas. A large amount of waste remains after oil palm is used, which can still be recycled again and processed into fertilizer products through the organic fertilizer production line.
Oil palm
Palm has unique biological characteristics:
1. Long fruiting period and high oil content. The results began in the third year after the oil palm was planted, and it entered the prosperous production period in 6-7 years, with an economic life of 20-25 years. The oil content of oil palm fruit is more than 50%.
2. Strong adaptability, easy to manage. Oil palm can grow in arid and barren areas, with few diseases and pests, high and stable canopy coverage.
3. Low production cost, extensive management, convenient operation and long term of return on investment.
Palm waste made organic fertilizer
As an example, oil palm is a cash crop in many countries, especially in Southeast Asia. The harvest of oil palm resulted in a large amount of biomass and waste. Biomass and waste are produced in a variety of forms, including harvested palm trunks, palm leaves from daily pruning, empty bundles, shells, fibers, and effluents from the processing of the entire fruit bundle.
Although factory waste, filter cake (or factory sludge) and washing waste have been converted into useful by-products, such as fertilizer, fuel, animal feed and biogas, most of the biomass and waste produced by the harvested oil palm has not been treated in a satisfactory way. For example, the most common way to deal with biomass and waste is combustion. The combustion of biomass and waste materials has resulted in a lot of pollution and is considered unsatisfactory. Now many countries (including Indonesia and Malaysia) prohibit the burning of biomass and waste from oil palm.
In the treatment of oil palm waste, it is similar to the biomass and waste of jujube, which can be decomposed or decomposed in a long period of time.
Other ways of treating leaves include simply piling up around the harvest site, where biomass or waste can decay or decompose over a longer period of time. However, this method is generally unsatisfactory when the rate of accumulation of biomass and waste materials is greater than the rate of decay. Therefore, The fertilizer production line manufacturers recommend that compost palm waste into organic fertilizer products.
The compost fermentation of palm waste can not only solve the waste, but also realize the economic benefits of two times recovery. Fertilizer granulator can make the rotten waste into organic fertilizer products suitable for different crops to achieve ecological balance.
If the excrement of livestock and crop straw are not fully and reasonably utilized, resources will be wasted, which will cause pollution and threat to people’s living environment. Through the transformation of chicken manure organic fertilizer production equipment into bio organic fertilizer, the fertilizer granulator can also process organic fertilizer into solid particles and improve the product value. Organic fertilizer equipment can not only make rational use of resources, but also reduce environmental pollution, beautify the environment, promote agricultural economic development, with good economic and social benefits.
Chicken manure organic fertilizer
Chicken manure organic fertilizer processing
No matter the scale of the chicken manure organic fertilizer production line, according to the different requirements of the existing raw materials and finished products, the overall process is divided into two stages, namely, the early fermentation stage and the production granulation stage. In the fermentation stage, compost dumper is needed to compost turner to make them mature rapidly on a large scale. No matter it is the production of powdery or granular chicken manure organic fertilizer, each process is indispensable. If due to the limitation of funds, traditional fermentation mode can be adopted. But since it is a bio organic fertilizer production project, of course, it is impossible to be the same as the traditional production mode, if only one or two processes use the traditional mode.
When processing manure with organic manure equipment, it is necessary to pay attention to whether the quality of organic manure is qualified. Once there is a mistake in one step, it will lead to the quality problem of organic manure. The equipment that can be selected for organic fertilizer granulation includes rotary drum granulator, flat die pellet mill, organic fertilizer granulator, etc., which is determined according to the raw materials and output.
In the production process of chicken manure organic fertilizer, the control of water is the key factor. Too dry makes it difficult for organic fertilizer to play a role in actual production, prolonging the action time, and too wet is not conducive to the preservation and use. At the same time, the water index and drying degree affect the survival period of bacteria. In the bio organic fertilizer project, the chicken manure organic fertilizer dryer is an indispensable equipment in this important link.

Application of fertilizer automatic batching system
The growth of crops needs a variety of nutrients, for example, nitrogen, phosphorus and potassium are the basic elements which need a large amount. When using the electronic batching machine for batching, it is necessary to set a silo for each raw material containing these elements. The raw materials used in the production of organic-inorganic compound fertilizer are all powdery. After the raw materials of these different components are configured according to the set proportion, they are made into compound fertilizer particles by the disc granulator machine. In the production of mixed fertilizer, granular raw materials can be placed in the batching system.
