We are professional fertilizer machine manufacturers. The main products are: organic fertilizer equipment, compound fertilizer equipment, blended fertilizer equipment, granulator, dryer, mixer, etc. Welcome to buy.

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.

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. 

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.

Organic fertilizer production line configuration requires smooth equipment layout, compact structure, save space as much as possible, and reduce construction civil investment; adapt to the characteristics of cow dung material, durable equipment, small maintenance, low system energy consumption, low operating costs; convenient equipment operation, minimize Manual operation errors reduce labor intensity.

It is suitable for large-scale organic fertilizer fermentation and is a land cost. It’s ideal for high organic fertilizer manufacturers.

2) Double-shaft horizontal pulverizer; its function is to pulverize the fermented materials to achieve uniformity. The equipment also has the advantages of reasonable structure, convenient installation, high efficiency, significant energy saving, durability and easy maintenance.

3) Horizontal mixer; the function of its equipment is to crush, mix and mix various materials such as crushed materials and NPK inorganic fertilizers and other additives in a certain proportion.

4) Disc granulator; the function of the fertilizer granulator machine is to granulate the materials that are mixed and stirred uniformly, and to shape the materials. Its advantages are that it is suitable for farming raw materials, especially suitable for organic materials, and has stable granulation, high particle forming rate, and the appearance of finished particles is uniform and difficult to break.

5) Drum dryer; its equipment is used to further remove the moisture content inside the processed material particles to achieve the moisture content standard.

6) Rotary cooler; the function of this equipment is to cool the dried granular material. Because the dried material temperature is too high, it is not easy to save, so it needs to be processed by cooling machine, and the cooled granular material is convenient for storage and quality.

7) Drum screening machine; the size of the granulated materials produced from the granulation molding program will have a certain difference, so it needs to be processed by a screening machine to screen out unqualified granules for secondary crushing.

8) Automatic packaging machine; the material granules processed in series can be transported to the equipment by the hoist for final weighing and packaging. The automatic packing scale is controlled by microcomputer, which can realize multi-range measurement with high weighing accuracy Automatic bag clamping, sewing bag, automatic tare and detection functions, its advantages are unmatched by manual packing.

Due to the increasingly high level of agricultural modernization, organic food has received increasing attention. The emphasis that follows is on ecological agriculture. Because only ecological agriculture can produce ecological food. In this regard, both from the strength of national policy support and in practical actions, the country has invested a lot of support in this regard. The widespread use of organic fertilizers as we know it is one of the best examples. It can be said that in the future, organic fertilizer will gradually replace other fertilizers and become a necessary fertilizer for crop growth. So what is the development trend of organic fertilizer?

In terms of organic fertilizer production, it has received strong support from many experts. At the same time, it has also received strong support from the country in terms of equipment. Many places now have specialized equipment and production lines for organic fertilizer production in order to produce better organic fertilizers. In terms of policy support, many local governments have given much help. In particular, it has received strong support in the utilization of waste and the treatment of some discarded household goods, as this not only disposes of household waste and reduces environmental pollution, but also turns waste into a treasure and produces valuable organic fertilizer. In many places, this is a very good measure, so many local governments will provide strong support for the production and use of organic fertilizer, and even provide certain subsidies from the economic perspective to encourage people to use organic fertilizer.

It can be said that it is the widespread use of organic fertilizers that can gradually transform our agriculture into pollution-free agriculture, and enable more organic food, fruits, and vegetables to come to our table.

With the development of economy and the acceleration of urbanization, the urban population has surged, and the pollutants in cities are also increasing. In fact, urban pollutants can be turned into organic fertilizer through treatment. Organic fertilizer is necessary for organic and ecological agriculture. It can improve soil properties, improve soil fertility, increase the yield and quality of agricultural products, and curb environmental pollution. It is recommended that the government increase investment and design the classification and treatment of urban pollutants in the planning of urban construction, and treat this as a new industry to treat urban pollutants into organic fertilizers with low prices and convenient transportation, so as to turn waste into treasure for agricultural services.
