The complete set of npk manufacturing process can usually be divided into: raw material batching, raw material mixing, raw material granulation (drum granulator, counter-roll granulator), particle drying, particle cooling, particle classification, finished product coating, Final product packaging.

NPK fertilizer production line (NPK) is our fertilizer production equipment product with stable operation, high quality and easy maintenance and repair. High ball formation rate, less external circulation materials, low comprehensive energy consumption, no pollution, and strong adaptability.

At present, the compound fertilizer mixing method of the roller extrusion granulator has developed rapidly both in foreign countries and in China. The roller extrusion granulator strictly controls the particle size, so how does the roller granulator work? 

The double roller granulator uses the motor as the power to connect the belt, and drives the two counter-roll dies to rotate toward each other. The semi-circular grooves of the same size are distributed on the die, and the die rotates to the contact point to form a circle. The resulting particle size is determined by the abrasive tool selected and is formed in one pass. It is suitable for organic fertilizer, compound fertilizer, feed, chemical industry and other fields.

The roller extrusion organic fertilizer granulator is an improved product that absorbs the new technology of the international granulator. The machine is equipped with a feeding system that is connected with a pre-continuous feeder with a machine touch device and a forced feeding screw feeding hopper, which ensures the continuity, adequacy and uniformity of the feeding, which is an important step. The paired rolls are engraved with evenly distributed arc grooves, which is beneficial for the material to bite into the rolls, causing the arc groove to seal the cavity (belt) during operation, and also beneficial for the compaction of the material, reducing the forming pressure of the mechanism and the load of the main engine, and improving the rolling process. sheet manufacturing rate.

A cow produces approximately 30-40 kilograms of excrement per day, and a small organic fertilizer production line can be established in a cattle farm with 5000 cows. So what are the production processes for cow manure organic fertilizer.

The process flow and supporting equipment of cow manure organic fertilizer production line

The production process of organic fertilizers such as cow manure involves steps such as fermentation, crushing, mixing, granulation, screening, drying and cooling, and packaging; The equipment used includes organic fertilizer fermentation equipment, forklift+feeding bin, semi wet material crusher, dual axis mixer, organic fertilizer agitator granulator, organic fertilizer drying and cooling equipment, drum screen, automatic packaging and other equipment. Other configurations include coating machine, automatic batching system, etc.

The equipment in the organic fertilizer production line is relatively mature and has great advantages compared to traditional processes. For example, a semi wet material crusher is specifically suitable for crushing organic fertilizers. After fermentation, it can be directly crushed without the need for other equipment and processes; Stirring toothed granulators also have many advantages over disc granulators.

The price of a complete set of cow manure organic fertilizer production line depends on the configuration and different yield sizes. We should pay attention to the following aspects when investing in organic fertilizer plants.

1. Raw materials. The raw materials for organic fertilizer are poultry and livestock manure, or some kitchen waste, mushroom residue, etc. Because these raw materials have no other uses, the cost is usually not high. It is important to note whether the surrounding supply of these raw materials is sufficient. The farther the distance, the higher the transportation cost.

2. Labor costs. A complete set of cow manure organic fertilizer production line has about 4-6 workers. Of course, different production line configurations require different amounts of labor, including fully automatic packaging machines that do not require workers, as well as semi-automatic packaging machines.

35. Factory and civil engineering costs. The organic fertilizer production line has low requirements for the production plant and does not require large-scale construction. Mainly the cost of the venue. There is no need for major adjustments to the subsequent factory buildings, as they have a long service life and relatively low annual costs.

Small-scale organic fertilizer production equipment generally refers to a production line with an annual output of less than 10,000 tons. Judging from a 5,000-ton sheep manure organic fertilizer production line, the investment amount is about 80,000-100,000 yuan. This is a powder organic fertilizer production line. If it is a particle npk fertilizer production line, tens of thousands of yuan of equipment will be added for equipment such as a pair of double roller granulator.

Organic fertilizer equipment is a good choice for processing cow and sheep manure. The cow and sheep manure fermented by the turning machine does not contain any bacterial disease eggs and is a first-class high-quality fertilizer. It improves soil quality and is the first choice for growing flowers, vegetables, tea and pastures. The cow and sheep manure organic fertilizer equipment not only greatly improves the economic value of manure, but also solves the pollution problem of Xinjiang breeding industry. This effective method of dealing with cow and sheep manure pollution has been recognized by more and more investment projects.

If deep processing is to be carried out, a fermentation turning and throwing machine should be used in the fermentation process of the npk manufacturing process. The subsequent processing will crush the fermented materials that have completed the secondary aging and stacking process, and enter the mixing and stirring system. Before mixing and stirring, according to the formula, Add N, P, K and some other trace elements into the mixing and stirring system, start stirring, and transport the mixed materials into the granulation system, as well as screeners, dryers, belt conveyors, etc. The purpose is to make powdered organic fertilizer or granular organic fertilizer that sells better.

We are a professional chemical fertilizer equipment manufacturer, specializing in providing a complete set of chemical fertilizer manufacturing process equipment, which process and organic fertilizer equipment are more suitable for specific production. If you need to consult our factory professionals in detail when planning the construction of organic fertilizer plants.

Nitrogen, phosphorus and potassium fertilizers are essential nutrients for plant growth. What equipment is needed to produce npk fertilizers? The process flow of the complete set of npk production line equipment can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final product packaging. The complete set of equipment has less investment, quick effect and good economic benefits, and the npk fertilizer production line has a compact layout.

1. Forklift feeding bin: The function of the feeding bin to ensure uninterrupted production is to temporarily store materials, and then connect them to feed the production line. It is divided into ordinary feeders and uniform feeders.

2. Mixer: the most common are vertical mixer and horizontal mixer, which are mainly used for mixing raw materials and auxiliary materials to make the distribution of organic matter more uniform.

3. Granulator: the most common are double roller granulator, disc granulator, tooth stirring granulator, drum granulator, the granules produced by each granulator are different, and the applicable materials There are certain requirements, and the variety of granulator can be determined according to the selection of raw materials.

4. Dryer and cooler: The equipment is cylindrical and rotary, and the dryer dries the excess water in the particles, which is convenient for material storage and not easy to deteriorate. The cooling machine cools the particles in time to facilitate and quickly enter the next process.

5. Screening machine: the most common are trommel screening machine and vibrating screening machine, which have two main functions. Screening out oversized particles needs to be crushed and re-granulated. The powdery material is returned to the granulation process for re-granulation, and qualified particles are retained. It is transported to the next sub-process by the belt conveyor.

6. Coating machine: A layer of coating agent is added on the surface of the particles, so that the appearance of the particles is more rounded and beautiful, and the quality is better, which is convenient for the permanent retention of materials without caking and deterioration.

7. Automatic packaging machine: automatically package into bags according to the set weight, improve efficiency, maintain particle quality, and save labor.

In fact, cow manure contains a large amount of nutrients required for crop growth. Adding it can make good use of it, not only protecting our living environment, but also making it a good entrepreneurial project.

Add organic solid waste (such as straw, sawdust, rice bran, soybean cake, etc.) with a moisture content of less than 60% to fresh cow manure as an auxiliary material and mix it with microbial fermentation agents to regulate water content, ventilation, and carbon nitrogen ratio (carbon nitrogen ratio between 30-40), so as to control the moisture content of cow manure at around 60%, with watermarks between fingers but not dripping. Through continuous aerobic fermentation in a pool, it is fully decomposed, sterilized, deodorized, and dehydrated. The moisture content of the decomposed material is generally within the range of 30-35%, and after screening, it can be directly used for granulation production of granular or powdered organic fertilizers.

The fermentation method for powder cow manure organic fertilizer production line is as follows:

1. Stack cow manure, straw, and other auxiliary materials, as well as fermentation agents, in a certain proportion on the fermentation site.

After the fermentation temperature of compost rises, it can be flipped. When the fermentation temperature is about to reach 70 degrees, an organic fertilizer flipper should be used for flipping, and flipping should be done every other day.

When the temperature of the compost decreases, the material is loose, there is no odor or slight ammonia smell, and white mycelium is produced inside the pile, it indicates that the organic fertilizer has matured and can proceed to the next process.

4. The powder cow manure organic fertilizer production line uses a forklift to transport the organic fertilizer to the production workshop. Through a series of production processes, it is made into granular organic fertilizer and packaged into bags.
