With the continuous popularization of organic fertilizer, more and more people begin to use organic fertilizer for production and planting. There are many raw materials for producing organic fertilizer, but many double roller granulator use manure to produce organic fertilizer.

The green, ecological and sustainable development of the circular economy of the double roller granulator not only ensures food safety, but also solves the environmental pollution caused by feces. Moisture control of organic fertilizer fermentation: 65% of organic fertilizer fermentation moisture, how to judge the moisture content? Grasp a handful of materials with your hand, you can see the watermark on your finger, but it will not drip, it will fall to the ground and spread. High water content will lead to poor ventilation, slow temperature rise and unpleasant smell. High water content can be obtained by adding straw, sawdust and mushroom residue. When the water content is too low, the fermentation is slow. When the water content is too low, the manure or water separated by the solid-liquid separator can be used to ensure the water content.

Animal manure processing equipment can process animal manure into organic fertilizer in a short time, so it is also called organic fertilizer production equipment. When the equipment system is working, the feces of livestock and ingredients are sent to the mixing mixer according to the specified proportion for mixing and mixing to make it uniform. The mixture is further mixed by the screw conveyor and sent to the host pressurized mixer. The temperature of the mixture in the machine is raised by the pressure friction of the pressurized mixer, killing or inhibiting low-temperature bacteria, killing ascaris eggs and harmful bacteria, and then providing appropriate air and water, Create suitable conditions for thermophilic bacteria fermentation, complete the rapid fermentation, then crush and loosen it through a grinder, and finally send it to the storage yard for stacking to become organic fertilizer.

1. Low energy consumption oforganic fertilizer roller granulator: extrusion granulation is the granulation of materials at room temperature. Compared with other granulation methods, it does not require drying measures such as fuel oil and gas. The production only requires power consumption and a small amount of cooling water (for roller shaft cooling), and the power consumption per ton of product is only about 30 kW/h.
2. There is no need to add adhesive to the organic fertilizer roller granulator: other granulation processes are basically wet processes, which must have a drying process, with high energy consumption and high product moisture. However, dry granulation does not require additional additives, but only uses the intermolecular force of the material itself, simplifying the process and reducing energy consumption.
3. The investment of theorganic fertilizer roller granulatoris low: because the drying process is omitted, and the return ratio is low (accounting for about 35% of the total feed of the extruder), the process flow is simple and the investment is low.
4. Wide range of applicable raw material particle specifications: extrusion granulation has no special requirements on the particle size of raw materials. Both 1~4mm granular materials and fine powder materials can be used. Unqualified powder materials and powder products can be better used, and the cost can be reduced by using powder materials.
5. Wide capacity range oforganic fertilizer roller type extrusion granulator: for the extrusion granulator, the effect of economic scale is not obvious, and the unit capacity of 1~50 t/(h. set) can be economically designed, so the applicable capacity range is wide.

The only disadvantage of producing granular fertilizer by roller extrusion granulation is that the product shape is irregular particles, but the irregular particle shape has no effect on the application of fertilizer, and the dressing process can be added to further round the particles. The fertilizer produced by extrusion granulation has sufficient strength, less dust, no agglomeration, narrow particle size distribution range, and good fluidity, so it has good economic benefits.

Organic fertilizer can make microorganisms in soil multiply, especially many beneficial microorganisms, such as nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, etc. These beneficial microorganisms can decompose organic matter in soil, increase soil aggregate structure and improve soil composition.

Microbes propagate rapidly in the soil, they are like an invisible net, very complex. After the death of microbial cells, many small pipes will be left in the soil, which not only increases the permeability of the soil, but also makes the soil soft and soft, so that nutrients and water are not easy to lose, increasing the soil’s water storage and fertilizer storage capacity, and avoiding and eliminating soil hardening.

The beneficial microorganisms in organic fertilizer can also inhibit the reproduction of harmful bacteria, so less chemicals can be used. If it is applied continuously for many years, it can effectively inhibit soil pests and save manpower, financial resources and pollution.

At the same time, organic fertilizer contains various active enzymes secreted by animal digestive tract and various enzymes produced by microorganisms. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. Long term sustainable use of organic fertilizer can improve soil quality. If the soil quality is fundamentally improved, there is no need to worry that high-quality fruits will not be planted.

Organic fertilizer granulation equipment: granulation of mixed fertilizer is an important process of dry powder granulation process. It is not only related to the internal and external quality of products, but also to the size of output and cost. In addition to the physical and chemical properties of materials, the granulation process is closely related to the form and mechanical properties of granulation equipment. The main types of granulation equipment include disk granulator, drum granulator, double shaft granulator, extrusion granulator and spray granulator dryer.

Pig dung and chicken dung are one of the most notorious stinky dung in the breeding industry. Pig manure should be a good farmyard manure, and a high-quality organic fertilizer resource for soil improvement. However, if fresh pig manure is applied directly, it will inevitably cause crop root injury, disease, grass damage and other negative effects. According to statistics, about 1000 pigs are sold annually, and about 1.2t of fresh pig manure is produced every day. If the natural composting and fermentation process is used in the past, there are several disadvantages: first, the composting time is long (4-6 months), and the effect is poor; Second, long-term stacking not only occupies the site, but also causes pollution to the surrounding environment. Third, the natural composted fermentation faeces are rotten, wet and stinky, which is difficult to transport and directly apply.

The pig manure harmless treatment organic fertilizer production line technology is analyzed by taking the manure treatment of pig farms with a breeding scale of about 1000 pigs as an example. The microbial fermentation strain used in this project is a highly effective composite microbial agent that can rapidly decompose livestock manure, crop straw sludge, agricultural by-product processing organic waste, etc., and has the following significant characteristics:

A Fast maturing organic solid stacking material, suitable for a variety of different composting substrates and different organic fertilizer dumping equipment;

B The content of effective living bacteria is more than 5 billion/g, and the addition amount is small and the cost is low. It only costs 8 yuan per ton;

C temperature rises quickly. When the ambient temperature is 0-5C, the composting temperature can rise to 55-70 “C within 48-72 hours;

D The composting cycle is short (7-10 days), which can save a lot of site and production costs:

E can quickly and effectively eliminate the peculiar smell in materials;

F has less nutrient loss, and the total nitrogen loss rate is less than 1%, which can effectively maintain the effective nutrient of compost. After fertilizer application, it can increase the number of microbial flora, improve the physical and chemical properties of soil, adjust the soil pH value, and has significant fertilizer effect;

G The high temperature of compost lasts for a long time, which can kill the bacteria and eggs in the raw materials of compost, make the compost reach the harmless standard in a short time, and become an efficient commercial organic fertilizer meeting the requirements of green food production.

H The amount of organic fertilizer produced by fermenting pig manure with BM strain is small, which can be used as base fertilizer: 80-150 kg/mu for cash crops such as vegetables, 80-100 kg/mu for grain, 80-100 kg/mu for tea trees, 1-3 kg/tree for fruit trees, and 0.5-1 kg/m2 for lawn.

Disc granulation process is simple and relatively cheap. In the organic fertilizer production line, most customers will choose disc granulator. How to improve the pelletizing rate of disc granulator has always been a concern of customers, so how to improve the pelletizing rate of disc granulator? What matters should disc granulator pay attention to when processing organic fertilizer?

Control the moisture content of granulating particles
In the production process of fertilizer granulator, how to preliminarily test the particle water quantity? A simple and practical method, hand feeling method: grasp a ball of materials from the disc granulator, and the hand can form a ball. It is appropriate to release it with a touch of a finger. The grain thus made has high yield and is not easy to block the screen surface.

Strictly control the quality of powder fertilizer
According to the formula of organic fertilizer, carefully control the quality of various raw materials.
Iron block, stone larger than 10 mm and wood block larger than 10 mm are strictly prohibited for raw material discharging and feeding. Rice bran and sand can’t have many quality indexes either, which seriously results in low yield.

Key technology of operating disc granulator
Do well in operator’s technical training of disc granulator, improve workers’ technical quality and operation skills.

Select the nozzle of disc granulator and adjust the nozzle
Generally, B-type spherical screw or B1 type rudimentary spiral nozzle is the best choice for disc feeder.
According to hydrodynamics, it has been proved that the larger the pressure is, the smaller the through hole is, and the larger the droplet diffusion surface is. Under the same pressure, the spray hole of the nozzle is small and the droplet density is small; the spray hole is large and the droplet density is large.

A new type of blade in the disc of the reformed disc granulator
Good blade, even and beautiful grain size, blade material must be 16m, blade is divided into front blade and rear blade, there is no gap between the two blades.

Organic fertilizer production process of sheep dung compost turning machine

4. The agitated ingredients are piled into strips about 3.0 meters wide and 1.2-2.0 meters high (the fermentation effect is better when the length is more than 3 meters). Every 3-5 days, the compost turning machine was used to turn the compost.

With the new organic fertilizer production line equipment, you don’t have to worry about the shortage of organic fertilizer in your life. This kind of organic fertilizer equipment has many functions. In addition to solving the problem of insufficient organic fertilizer, it can also solve other problems. So, what problems can organic fertilizer equipment solve?

The whole organic fertilizer production line for granular organic fertilizer includes compost turner machine, organic fertilizer crusher, horizontal mixer, rotary drum granulator or new organic fertilizer granulator, rotary dryer, rotary cooler, drum screening machine, circular throwing machine, coating machine, quantitative packaging scale and belt conveyor or bucket elevator for conveying materials between equipment. These machines form a high configuration organic fertilizer production line, most of which are large-scale and competitive companies.

In the production process of organic fertilizer granulator, the raw materials are required to have a certain viscosity. Some raw materials are relatively loose after fermentation and are not easy to granulate. A certain amount of water or adhesive needs to be added to improve the viscosity of materials. The disc granulator and raw meal granulator of organic fertilizer equipment adopt the granulation method, and water or adhesive is added in the granulation process to ensure the smooth granulation of materials. The new organic fertilizer granulator adopts wet granulation, and the fermented materials can be directly granulated without other process operations. The double roller extruding granulator is a non drilling room temperature granulator suitable for granulation of materials with low viscosity and low moisture content.

If the water content of the material is too high, some dry materials can be added appropriately to neutralize the water. If the water content is too low, an appropriate amount of water can be added to facilitate granulation.

The new organic fertilizer granulator is a kind of organic fertilizer granulator that is constantly updated and transformed with the development of agriculture, the improvement of technology and the diversification of demand. The new organic fertilizer wet granulator can realize the material selection, as long as all kinds of organic matter after effective fermentation can be granulated through the new organic fertilizer granulator, breaking the limitations and obstacles of the traditional process. Before granulation, there is no need to stop the processing of raw materials, crushing and drilling tasks. Therefore, batching processing and direct granulation can be realized directly, which not only saves a small amount of power investment and effectively reduces the cost, but also improves the task efficiency, which is convenient, fast and satisfactory.
