Pig manure production process of organic fertilizer equipment
(1) Pulverization: After fermentation and storage for 1 day, pulverize, and dry, pulverize and sieve the fermented organic material with a compost manure crusher .
(2) Compounding and mixing: In the process of organic bio fertilizer making process, according to different soil conditions and different crops, inorganic nutrients and minerals with concentrated organic matter and trace elements are added, so that the fertilizer contains nutrients required for the growth of various plants. Elements such as nitrogen, phosphorus, potassium, sodium, manganese, zinc, copper, etc. According to the formula, nitrogen, phosphorus, potassium and fermented materials are mixed by computer in proportion, and then sent to the granulator for granulation. The formulations of organic and inorganic raw materials are mixed according to different series of products. Mix well in a fertilizer blending machine. If the ratio is 12%, about 12 tons.

(3) Granulation: Due to the production of biological fertilizers, organic matter is the main ingredient, with a lot of cellulose, poor forming conditions, and the addition of live bacterial groups with fertilizer-making function, and the production process is not suitable for contact with high temperatures. It is not suitable to use disc granulation and drum granulation in terms of material making methods, because these two processes require high grinding fineness of raw materials and high granulation moisture. Generally, the moisture content should reach about 30%. The load is large, the loss of effective bacteria is also large, and the ball formation rate is low (about 60% to 70%), the dust in the production process is large, and the operating environment is very poor.
Therefore, for the production of organic biological fertilizers, the dry granulation process for fertilizer should be used. The production is relatively good, the environmental extrusion has low requirements for raw material crushing, high forming rate (above 95%), low water content of the particles after opening, and low drying load, which can reduce the loss of effective bacteria, small dust, and operating environment. better. The compound fertilizer raw material adopts extrusion granulation. The raw materials enter the granulator, add an appropriate amount of water or steam, and bond to granulate. After granulation, the materials are sent to the dryer through the belt conveyor machine for drying. The particle diameter is 3.0-4.0mm, and the granulation rate is greater than 70%.
(4) Drying: In the production process of biological fertilizers, not only the water content of the formed granules generally exceeds the index, and low-temperature drying is required, but also after the organic raw materials are fermented, the water content is about 30% to 40%. The moisture content of the particles is generally between 15% and 20%, and the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. Therefore, the fertilizer drying process is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.
the design of biofertilizer making plant
In order to avoid the death of effective live bacteria due to excessive temperature during the drying process, the drying temperature of the material should not be higher than 60°C (generally 50°C). The difference is generally not more than 130 ° C, it is best to control the temperature of the hot air in sections, which can improve the thermal efficiency and avoid the death of effective live bacteria.
According to these characteristics, it is more appropriate to choose a drum dryer machine, which is suitable for low temperature and low moisture drying, and can control the temperature of hot air entering in sections to ensure that the material temperature is not higher than the specified temperature during the entire drying process. It can also add a natural air cooling section, so that the material can be cooled immediately after drying, which has a multi-purpose function. It is very suitable for the drying of granular biological fertilizers with good air permeability. Affected by any damage, the residence time and feeding speed can be adjusted to achieve the best drying effect in your fertilizer manufacturing plant. Since most of the hot air can be recycled and the thermal efficiency is high, the heat source can be the steam provided by the biogas boiler.
There is a secondary granulation zone at the front of the dryer, and the material can be granulated in this zone. Then, the material is lifted up by the lifting plate to be fully dried. The humid hot air is extracted from the tail of the dryer through the pipeline through the exhaust fan, and enters the sedimentation chamber for sedimentation. It is pumped out and recycled by the water pump. After the secondary dust reduction treatment, the exhaust gas is discharged into the atmosphere through the chimney.
(6) Cooling: The dried material is sent to the rotary drum cooler through the belt conveyor for cooling. The cooling process is mainly to use the fan to send the natural air into the cooler through the pipeline to cool the material. The wind direction in the cooler is countercurrent. The exhaust gas pumped into the settling chamber through the fan and pipeline is treated like the drying exhaust gas and discharged into the atmosphere.
The cooled material enters the sieve, the large particle material is crushed and then enters the return belt together with the sieved powder to be transported to the granulator for re-granulation, and the finished product enters the automatic weighing and filling machine for packaging.
What are the problems that need attention in the production process of organic fertilizers! First of all, the location of the organic fertilizer plant is very critical, it is best to be closer to the raw materials, the raw materials of organic fertilizer are generally locally sourced, if the supply of raw materials is guaranteed by long-term transportation, the cost will increase a lot.
After the raw materials enter the cattle manure fermentation machine to start fermentation, they should observe the moisture and temperature of the materials during the fermentation period at any time, control the changes in raw materials in time, make timely treatment, and use the aerobic composting machine to turn the pile to ensure the uniform and thorough fermentation of the materials. Fermentation bacteria can be added during fermentation to speed up the speed of fermentation, but it is not recommended to add other biological bacteria during this period, because the temperature of the material is very high during fermentation, and many beneficial bacteria cannot withstand the high temperature.
After the material is fermented by the fertilizer conveyor to the forklift silo for use, this silo is generally with speed regulation function, can be a good control of the feeding speed of the follow-up equipment, from the silo out of the mixer, this time can add a certain excipient to the raw materials, mixer We generally recommend designing two, one stirring and one discharging. Material mixed evenly into the crushing, crushing machine and the general crusher is not the same, because we need materials to maintain a certain amount of moisture, so the crusher to use semi-wet material crusher, this crusher for the material moisture in 20%-50%, can be fully competent for our organic fertilizer raw materials crushing.
Granulation is the whole production line most affect the final molding effect, the choice of organic fertiliser granulator is crucial, according to the different raw materials, the model we want to use is not the same, for example, we want to use cow feces as fertilizer, appropriately add some other organic substances (straw, sawdust, etc.), then our suggestion is the organic fertilizer tooth pelletizer, this model is the use of churning teeth and cylinder wall between the matching to make the material forced into granulation, so to some fiber coarser livestock and poultry manure effect is better. If our raw material is organic plus inorganic fertilizer, then we need to use organic fertilizer combination granulator, which can make the perfect combination of manufacturing granular fertilizer.
We all know that organic fertilizer needs to add a certain amount of biological bacteria, but high temperature will kill and reduce the survival of biological bacteria, so the control of temperature is crucial, if the yield is large, we generally recommend increasing drum dryer machine and reducing the temperature to ensure the survival of biological bacteria. It is also possible to consider adding a coating cylinder after drying to wrap the biobacterium directly on the surface of the material.
When referencing compound fertilizer, this is simply a type of fertilizer which includes 2 or more components. When you have ever used NPK fertilizer, this is amongst the many types that are offered. Of all of the nutrients that happen to be included with these different fertilizers, nitrogen is usually the most essential. Potassium and phosphorus also play a vital role in producing most crops. However, there are so many others which might be useful, based on the crops you might be growing within the period that you are currently doing the planting. The following is an overview of just how the compound fertilizer production process works if you are considering this being a project that for you to do all on your own.
Compound Fertilizer Production Process
This starts off with storage bins that can have an abundance of powdery components. These are the basic nutrients that might be combined together, usually as appellate, that will then decompose in the ground as soon as they are spread to the surface. Production plants are often quite large. It can involve a variety of components. This will include a fertilizer crusher, packing machine, fertilizer mixer, and dryer that may make sure that excess moisture is removed. Furthermore, a rotary screener is frequently used to filter the types of materials. By removing unwanted components, your fertilizer will likely be pure and may produce the best results.

The Blending Technique For Producing Granules
Blending every one of these materials together can either be completed manually, or it might involve an even more complex process. A lot of the production systems today are controlled by computers. This may cause the combination in the different nutrients very exact. Whether this can be a large-scale system, or one built to produce just a few a lot of fertilizer annually, you will need a space to put everything. It must also be arranged, including conveyor belts, which will help inside the production process. The blending method is the procedure for weighing materials that you are used to produce the fertilizer pellets. These will likely then be combined together, rotated, and ultimately processed into compound fertilizer pellets which can be used or store.
In Which The Blending Occurs
This typically occurs on the inside of a rotating drum granulation machine. The rotating cylinder will probably not merely mix the numerous components and definitely will also be involved within the formation of the pellets. This will be a significant element of your compound fertilizer granulation line that could work nearly 24 hours a day. The blending process, given that the measurements are already done efficiently, will cause a highly efficient fertilizer for your personal business. In some instances, you may produce as much is 20 a lot of this product every hour. This is great for large-scale operations, or firms that have multiple properties where several types of crops are grown.
The design of compound fertilizer production line
From start to finish, the compound fertilizer production process is very elaborate. It calls for all the components that were mentioned. Having an ample availability of nutrients to use, and the machinery to complete the task, producing 1000s of plenty of this product is extremely easy to accomplish. Should you would prefer not to purchase your compound fertilizer making machines from third-party source, obtaining one of these brilliant systems could be advantageous. While the initial expense is high, they will often buy themselves within a long period, which makes this an intelligent and profitable decision to create.
The drying efficiency of drying equipment in organic fertilizer production line is more important to the firing temperature. The change of firing temperature directly affects the drying quality, energy consumption and refractory brick life, so it is very important to strictly control the firing temperature.
But we will find that the firing temperature will always change.
If the firing temperature becomes lower, the feeding amount of the dryer should be adjusted to reduce the material. The range of reduction is based on the predicted range of temperature reduction. According to the variation of the feeding amount and the situation in the dryer, the corresponding air and coal consumption should be adjusted in time.
When the firing temperature becomes higher and the feed rate is at a higher level, the coal should be reduced first. The extent of reduction depends on the temperature of the industrial dryer has increased, rather than rush to feed. Only to find out the reasons for the change of the firing temperature of the drying equipment, and solve it pertinently. In addition, timely report to the superior in case of any change of temperature.
(1) Sealing control of dryer. It can be partially sealed, integrally sealed or closed chamber, etc., and the dust producing point can be sealed with a sealing cover, which can greatly reduce the material scattering and dust.
(2) Eliminate the height potential energy difference of dryer. This is the main reason of dust spilling. The elimination of height potential energy difference is caused by powder drop of hopper, protective cover and chute of handling equipment. We should try our best to reduce the fall and the inclination angle of the chute. Some airtight chambers are better to cause negative pressure, which is conducive to the collection of dust.
(3) The transportation equipment with good sealing performance shall be used to reduce the height difference and inclination angle of discharge material flow, and the flow separation facilities shall be set as far as possible. It can not only enhance the configuration flexibility and efficiency of each operation room, but also reduce the scattering and dust.
(4) Use the exhaust system. In order not to let the dust bring more pollution, we can also remove the indoor dust through the exhaust system, that is to remove the indoor exhaust gas.
1. The welding residue shall be removed in time during welding. Pay attention to the drying machine equipment welding or repair welding problem is actually very simple, help to better understand, hope to help you through the high temperature dryer equipment drying materials, sealing drying efficiency and energy consumption directly affect, and equipment due to high temperature, high pressure and cylinder easy to cause equipment corrosion cracking, sealing off phenomenon, so we need to do a good job in welding, welding parts need to clear Except.
2. The corresponding professional welding equipment is more important. The temporary fixed driving device in the barrel shall be welded and cleaned. After cleaning the metal luster, to avoid impurities in the welding, welding effect, and gear, bearing lubrication, ensure the normal operation of the cylinder, welding is convenient, and service life will affect the equipment specification of the cylinder welding.
3. Carry out professional welding inspection. The number of welding repair parts is not more than 2 times, so the selection of professional welding equipment, welding personnel must pass the welding inspection, bending test, tensile strength test, qualified personnel to participate in the welding equipment, so that welding is not only in production, but also should pay special attention to the requirements of production personnel, production personnel only through technical drying equipment production safety.
Most of the dryer equipment should pay attention to the problem of welding, only from the production to grasp the quality, can ensure the quality of the production of products, this is in the production process should pay attention to the problem. The quality of equipment is directly related to welding, and the quality of welding directly affects the quality of drying equipment.
Direct drying mode. Its main technological process is that chicken manure is directly spread out in the air by hand, dried in the sun, crushed and directly packaged as a product for sale. This mode has the advantages of low cost and simple operation, but it also has some problems as follows:
1.It covers a large area and pollutes the environment.
2.It is difficult to guarantee the quality of the product due to its large volume, low nutrient and secondary fermentation.
Dry chicken manure mode. Its technological process is that chicken manure is directly processed through high temperature, heating, sterilization and drying by chicken dung drying equipment. The dried chicken manure with a moisture content of about 13% is directly sold as a product. The advantages of this model are:
1.Large production and high speed;
2.The product has stable quality and low moisture content.
However, there are also some problems, such as:
3.The quality of the product is not reliable because of its dry surface, bad smell and secondary fermentation after soaking in water.
4.The organic matter content in chicken manure is lost in the process of processing, which results in substandard.
Biological fermentation mode. It mainly has the following three fermentation modes:
1.Fermentation in fermentation tank. The main technological process is that chicken manure, peat and sawdust are mixed into the cement tank, then fermented with oxygen and mixed with nutrient rich bacteria agent. After fermentation, it is crushed, secondary aging and decayed to increase nutrient content, and then deep processing such as granulation is carried out, and the products are screened and packaged.
2.Direct composting. The main technological process is to mix chicken manure with straw or peat, pile up about 1 meter high, compost at high temperature, periodically turn and ventilate fermentation, and use it as product after fermentation.
3.Tower fermentation. The main technological process is to mix chicken manure with sawdust and other auxiliary materials, and then connect with biological agents. At the same time, the tower body automatically turns and ventilates to accelerate the fermentation and deodorization of chicken manure by using biological growth. After a fermentation cycle process, the products basically come out of the tower.
