Automatic packaging equipment for NPK fertilizer production line

fertilizer granulator Mar 31, 2023

 NPK fertilizer production line industry granular material quantitative packaging system commonly used bucket quantitative packaging scales, divided into two types of pneumatic and electric.

1. Pneumatic quantitative packing scale and electric quantitative packing scale
A wide range of pneumatic quantitative packaging scales. The advantages are fast packaging speed, fewer electronic components, and simple failure judgment. The disadvantage is that the ambient temperature is required, especially in high-cold areas in winter, there is a risk of icing in the air pipelines in the buildings without heating, which affects the braking system, so anti-icing measures should be taken in high-cold areas.
Electric quantitative packing scales have only appeared in recent years, and manufacturers are mainly concentrated in Harbin. The original intention is to adapt to the use in alpine regions. The advantage is that no anti-icing measures need to be taken. The disadvantage is that there are many electronic components, the circuit is complicated, and the failure is difficult to judge. The packaging speed is slower than the pneumatic quantitative packaging scale.

2. Hanging mode selection of quantitative hopper
No matter what kind of quantitative packaging scale, we think that the 3-point type hanging hanging weighing hopper has good stability, but the price is relatively high. 3 sensors are needed. If a fault occurs, you need to determine which sensor is faulty. The stability of the measuring hopper is worse (there may be some problems with the design of the side-hanging packaging scale used by me), but the price is relatively cheap, using only 1 sensor, the stability of the 2-point hanging weighing hopper is generally Not recommended for high speed packaging.

3. Selection of control table for quantitative packing scale
General pneumatic scales with F701 series have good performance, fast speed, high precision, and easy to master adjustment methods. Although the price is relatively high, but the value is good, the electric scale instruments are free from the manufacturers and are different.

Why use organic fertilizer manufacturing machines to grow plants

fertilizer granulator Mar 31, 2023

The nutrient content of chemical fertilizer is high and the fertilizer efficiency is fast, but the effective period is short and the nutrient is single. Organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can complement each other to meet the nutrient requirements of crops in different growth stages. Organic fertilizer manufacturing machine is indispensable for the growth of plants.

If only acid fertilizer is applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid roots combine with hydrogen ions in soil to produce acid, which will lead to acid strengthening and soil hardening. If mixed with organic fertilizer, it can enhance the buffer capacity of soil, effectively adjust the pH value and prevent the increase of soil acidity. In addition, the different nutrients needed by plants are made into granules by a roller granulator, and scientifically matched, the fertilizer efficiency is better.

Organic fertilizer improves soil. The beneficial microorganisms in the microbial fertilizer can produce carbohydrates, which account for 0.1% of the soil organic matter. Combined with plant mucilage, mineral embryos and organic colloids, they can improve the soil aggregate structure, enhance the physical properties of the soil and reduce the loss of soil particles. Under suitable conditions, it can also participate in the formation of humus. Therefore, the application of the microbial fertilizer produced by the organic fertilizer production equipment can improve the physical properties of the soil and help improve the soil fertility.

Investment production of small organic fertilizer production line

fertilizer granulator Mar 31, 2023

Small organic fertilizer production line (i.e. small organic fertilizer processing plant) is divided into two types: powder line and particle line.

Compared with powder line, granular line equipment needs more equipment and investment.

Therefore, the powder organic fertilizer on the market is usually cheaper than the granular organic fertilizer, which can be sold for 600 yuan / ton, and the granular organic fertilizer can be sold for 1000 yuan / ton. Some high-quality organic fertilizers cost thousands of yuan per ton.

Powder organic fertilizer production line needs to purchase equipment: fermentation overturning machine, crusher, packaging machine, etc. The equipment investment is between 80000 and 150000.

Granular organic fertilizer production line needs to purchase equipment: fermentation overturning machine, crusher, granulator machine for fertilizer, screening machine, packaging machine, etc. The equipment investment is 150000-450000. There are many kinds of equipment for organic fertilizer production, so we need to make different plans of organic fertilizer production line according to the different materials and output of customers. 

Organic fertilizer products can be made into granules or powders, depending on market demand. In order to balance nutrients and be suitable for transportation and storage, it is suggested that organic fertilizer should be processed into granular form. Granular fertilizer has good commercial properties and will not be automatically graded in the process of storage and transportation.

How to deal with feces effectively and pollution-free in pig farms

fertilizer granulator Mar 31, 2023

arge pig farms will produce a lot of pig manure every day. How to deal with pig manure is a very important problem for enterprises. In general, it is recommended to use manure composting fermentation process of organic fertilizer production line for treatment, so as to achieve harmless, and the farm will not be affected by odor and bacteria. Moreover, further processing pig manure into organic fertilizer can be sold on the market, thus turning waste into treasure and bringing a source of economic income.

Pig manure organic fertilizer production line is a fermentation process that uses the aerobic microorganisms contained in the fermentation agent to decompose the organic matter in pig manure which is not easy to be directly used by crops into small molecular substances, and integrates the advantages of deodorization, insecticidal, sterilization, nutrient improvement, and the elimination of secondary fermentation.

There are two steps to process commercial organic fertilizer in the organic fertilizer production line: early fermentation and treatment part and deep processing granulation part. Organic fertilizer equipment needs fermentation compost windrow turner, crusher, mixer, granulator machine for fertilizer, dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.

Because the pig manure can produce heat during fermentation, it can effectively kill the parasitic eggs and disease bacteria contained in pig manure, and prevent harm to crops; and the fermented pig manure can avoid the occurrence of root burning and seedling burning phenomenon because of its full maturity, so it is safer to use. In the fermentation process of organic fertilizer production machine, the macromolecular organic matter contained in pig manure is also decomposed into inorganic salts and minerals that can be directly used by crops, and the bacterial metabolites are generated, which enriches the nutrition of pig manure. What’s more, the fermentation process is also a biological deodorization process. The fermented pig manure has no odor and is more convenient to use. 

Precautions in the production process of biological organic fertilizer production line

fertilizer granulator Mar 31, 2023

The key to the production process of biofertilizer project is the choice of granulation method. According to the production process requirements, the currently used granulation methods of bio-organic fertilizer are mainly disc granulation and tooth-granulation. Due to different requirements of raw materials for different granulation methods, there are differences in the production process of biological organic fertilizer. At present, the production technology of Huaqiang organic fertilizer equipment mainly includes the following.

Using the disk granulation production process, the raw materials need to be dried to remove a certain amount of water (when drying, the raw materials are sterilized), and then crushed, and then a certain amount of acid and alkali is added to adjust the pH of the carrier and mixed with the inorganic fertilizer part, and sent The disc fertilizer granulator machine sprays a certain amount of bacteria during the granulation process, and the granulated product is dried and sieved at low temperature to obtain the finished product.

The tooth-granulation granulation process is to use the high-speed rotating mechanical stirring force and the aerodynamic force generated thereby to continuously realize the process of mixing, granulating, spheroidizing and densifying the fine powder in the machine, thereby achieving the purpose of granulation. The shape of the particles is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. The size of the particle diameter can be appropriately adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the rotation speed The higher, the smaller the particles, and vice versa.

The most important thing for the construction of organic fertilizer equipment is to adapt measures to local conditions. A good organic fertilizer production line is not only a guarantee of output, but also a guarantee of quality. Although the organic fertilizer equipment is only a combined process, the convenience it brings to people is unimaginable. Taking an organic fertilizer processing plant with an annual output of 200000 tons as an example, the equipment for the organic fertilizer production line is essential for starting an organic fertilizer processing plant. A complete set of organic fertilizer production line equipment, from fermentation equipment, crushing equipment, stirring equipment to the final coating machine, costs between 350000 and 550000 yuan. The price difference depends on whether you choose a high configuration equipment or a medium configuration equipment.

Factors affecting the processing of fertilizer by double roller granulator

fertilizer granulator Mar 28, 2023

Due to the significant advantages of its extrusion molding process, counter double roller granulator s have been widely used in fertilizer production and processing. Generally, fertilizer extrusion granulators are more commonly used. Due to the physical characteristics of fertilizer itself, the specific gravity, roundness, and strength of granular fertilizer produced and processed meet good specifications. All of this is due to the roller skin of the extrusion granulator. This article will introduce you to the knowledge of the roller skin.

The double roller granulator is produced and processed using a process without drying at normal temperature. The production and processing capacity of our factory is 1 ton/hour, 1.5 tons/hour, 2 tons/hour, and other models and specifications, which are available for users to choose based on their needs. The machine has low investment, good effect, and good economic returns. It is crucial to ensure simple operation, safe and reliable operation, and convenient maintenance during the production process. Raw materials have a wide range of applicability, and are relatively suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, and ingredients. The equipment has a high granulation rate.

For a pair of double roller granulator, the pair of roller skins that interfere with its granulation effect is the one. Circular pits of the same depth are regularly scattered on the roller skin. When two circular rollers rotate directly opposite each other, the two half pits fit each other to produce a circular abrasive tool with an overall empty core. During the production and processing of fertilizer, raw materials are continuously pressed into this type of circular abrasive by the roller skin, resulting in circular particles. This type of particulate matter not only has a beautiful appearance, but also has good strength, and is not easily crushed due to bumps or stacking.

For particulate matter, it is very important to standardize the production of the circular pits on the surface of the roller skin of the roller extrusion granulator. It not only interferes with the formation of fertilizer, but also interferes with the ability of the finished fertilizer to shell. If it cannot be successfully shelled, the fertilizer will stick to the circular pits and cannot produce the finished circular particulate matter. Compared to the organic fertilizer extrusion granulator, the corrosion of fertilizer on the roller skin can cause interference due to the untimely cleaning of fertilizer on the roller skin.

Another thing about the roller skin is its material. To put it bluntly, the extrusion granulator relies on the force of extrusion to produce fertilizer, so the roller skin will suffer certain wear under the action of external forces. Generally, good roller skins are made of high-grade materials and undergo strict heat treatment processes, which greatly improves the surface hardness of the roller skin of the extrusion granulator and increases its service life.

So how long is the service life of the roller skin of a pair of double roller granulator? Different roller skin processing manufacturers have their own supply channels, with greatly different materials. Moreover, the quality of heat treatment production can also interfere with its hardness, which can also have a certain impact on the life of the roller skin. More importantly, the frequency of use. If the continuous production and processing of fertilizer, the roller skin will consume quickly, so this issue cannot be generalized.

How to improve the granulation efficiency of organic fertilizer granulators?

fertilizer granulator Mar 28, 2023

 Organic fertilizer granulator machine is the latest technology product developed by the Agricultural Machinery Research Institute for many years of compound fertilizer processing equipment design and production experience, and has obtained national utility model patents. It is used to granulate various organic substances after fermentation, which breaks through the conventional organic granulation process. Before granulation, the raw materials can be processed into pellets without drying and pulverizing, and direct pelleting can be used to save a large amount of energy. How to increase the output of organic fertilizer granulator?

First. Control the moisture of granulated materials
1. According to the characteristics of the powder: composition, fineness, viscosity, humidity, temperature, etc., control the moisture content of the granules at about 30-28%.
(1) Too little water content. It is difficult to form balls. The yield is low.
(2) Too much water content. There are many large balls. The ball surface is sticky. It is easy to block the sieve surface.
(3) Appropriate water content, more balls and high yield.

2.How to check the particle water quantity in the organic fertilizer production line: the simplest and most practical way-feel method: the hand grabs a ball of material from the stirred material. The hand can form a ball. Touch it with your finger It can be loosened. There are many grains produced in this way. The output is high and it is not easy to block the sieve surface.

Second.Strictly control the quality of good powder
1. According to the formula of organic fertilizer, carefully control the quality of various raw materials such as chemical fertilizers.
2. When Raw materials are discharged and feeding. Iron blocks are strictly forbidden. Stones larger than 10mm. Wooden blocks larger than 10mm. Rice bran and sand should not have more quality indicators. More serious results in low yield.

Third.The main technical key of operating organic fertilizer granulator
1.The particle size of the fertilizer is 70-90 mesh.
2. Do a good job of employee technical training. Improve the technical quality and operating skills of workers.

Pig farms use complete sets of organic fertilizer equipment to treat manure and process fertilizer

fertilizer granulator Mar 28, 2023

The rapid development of pig farming has brought progress to China’s consumer market, but also brought environmental pollution issues. Pig manure pollution is a common source of pollution, which can reduce the quality of air and water sources and pose potential biosafety hazards. Methods such as fermenting biogas, making organic fertilizer, cultivating saprophytic animals, and planting edible fungi can reuse pig manure, which not only can better treat the manure, but also bring new benefits to the farm.

The cost of processing organic fertilizer is low. The important processes for organic fertilizer equipment processing are fermentation and granulation. Fermentation affects the quality of the entire production of organic fertilizer, and the quality of granulation directly affects the sales of organic fertilizer in the later stage. The process steps send livestock manure, ingredients, bacterial agents, etc. into a mixing mixer according to the specified proportion, and mix them to make them uniform. They are transported to a fermentation bed (trough type, bar type, or tank type) through a conveyor or forklift truck, After sufficient fermentation in the fermentation bed, it is crushed and loosened by a pulverizer, and then sent to a stacking plant for secondary aging to increase activity. After separation and impurity removal, it is processed into organic fertilizer through processes such as deep processing and granulation.

Generally, the raw material of organic fertilizer is mainly livestock manure produced by the livestock breeding industry. Firstly, the development situation of the aquaculture industry is very good, with a large number of large-scale farms, ensuring the supply of raw materials. Secondly, livestock and poultry manure is convenient for transportation and centralized treatment. Materials with low moisture content can be directly transported, while materials with high moisture content can be dehydrated by a solid-liquid separator before transportation. These are all advantages of manure organic fertilizer.

Organic fertilizer equipment has low production cost, sufficient fertility, simple and feasible methods, and can play a role in killing pathogenic pathogens in feces, which is relatively popular among aquaculture enterprises. The production process of organic fertilizer is actually a microbial fermentation process. Due to the large amount of nutrients contained in feces, these substances can provide basic carbon sources, nitrogen sources, growth factors, water, mineral ions, and other nutrients for microbial reproduction. The biological heat generated during the fermentation process can achieve a temperature of 80 ℃ and maintain it for several days, which can kill most insect eggs and pathogenic microorganisms without causing harm to the environment, The fermented feces are free of volatile harmful gases and pose no harm to the environment. The sale of organic fertilizer equipment also brings new income to the breeding farm, greatly improving the breeding efficiency.
