Differences between fertilizer and compound fertilizer processed in mixed fertilizer production lines

Mixed fertilizer is a raw material that combines two or more granular high nutrients. Especially suitable for areas with large land areas, complex soil types, and a wide variety of crops. Made from unit fertilizer or compound fertilizer through simple mechanical mixing, there is no significant chemical reaction during the mixing process. There are two types of production processes for compound fertilizers. One is called compound fertilizer produced by physical mixing, and the other is called compound fertilizer formed by chemical reactions of minerals containing nitrogen, phosphorus, and potassium.

BB fertilizer mixer (mixed fertilizer production line) adopts forward and reverse operation, and uses internal screw mechanism and unique three-dimensional structure to mix and output materials.

With the continuous development of technology, the chicken manure organic fertilizer process gradually entered our lives, it is an indispensable processing equipment in the breeding industry.

Why the chicken manure organic fertilizer manufacturing process is so important in our lives?

The organic fertilizer production line is a streamlined production operation mainly composed of a new organic fertilizer granulator. Each of them is very important. Especially in the production process, the idler determines whether the production is running efficiently. There is a traditional use of the organic fertilizer equipment production line. The characteristics add luster to people, and it is widely understood what kind of performance they have.

1) First of all, the raw materials such as animal manure are fermented and rotten. The whole fermentation process can kill harmful bacteria inside, and killing the bacteria is also an important step in the entire organic fertilizer production process.

2) Secondly, use the semi-wet material crusher of organic fertilizer crushing equipment to decompose the raw materials.

3) Matching raw materials is one of the most important processes in organic fertilizer production. Its main purpose is to add an appropriate amount of auxiliary materials according to the formula ratio to improve the quality of fertilizers.

4) After the material is uniformly mixed, mechanical granulation is required, which is also a crucial aspect of the entire production process.

5) The raw material obtains high-temperature energy after the drying step. The next step requires low-temperature cooling. Since water cannot be used for cooling, it needs to pass through the cooler equipment to separate the contact between the material and the water.

6) Sieving is to sieve out unqualified granule fertilizer. The screening equipment here has the advantages of high efficiency and easy operation.

7) The blended raw materials are used to produce granules, which are especially suitable for materials with high viscosity.

8) The material of the mixing vessel must be able to meet the standards required for production, such as pressure resistance, temperature resistance, resistance to catalyst erosion, and keep the product clean. Due to the different materials of the utensils, the production process and structure of the mixing utensils will also be different, so it can be divided into steel mixing equipment, enamel glass mixing equipment and lining mixing equipment.

Knowledge of chicken manure organic fertilizer production line.

The organic manure produced by the processing equipment of the chicken manure organic, fertilizer production line is divided into powder and granules in appearance. The various fertilizer sources in the market are mostly in these two shapes. When the farm is supporting the complete organic fertilizer production line. It is necessary to choose the corresponding production equipment according to the actual requirements of the finished materials.
 

The processing of powdered organic fertilizer production line only needs to use stacker, conveyor, semi-wet material grinder, horizontal mixer, packaging machine to meet the processing production, if the requirement is the production of granular organic fertilizer Add supporting granulation equipment, and we use disc granulator equipment for general chicken manure production and processing organic fertilizer, and then add drying equipment as appropriate according to customer output.
 

In addition to the treatment of chicken manure organic fertilizer production line supporting equipment, in addition to the treatment of turning waste into treasure, the particularity of the raw materials used in its production and processing also solves various environmental problems in chicken farms and the impact of pests and infectious diseases, because the farm Breeding manure is the main cause of air pollution, and a variety of flies will be parasitic in the breeding manure to cause infectious diseases.
 

Harm to all kinds of farmed animals in the breeding industry, and timely processing of these farming manures into organic fertilizers with many positive significance for agricultural production has fundamentally solved the problems of pollution, pests and diseases and infectious diseases in farms.
 

The current farms in the market are dominated by chickens, which account for more than 40% of the farmers, but the chicken farms will bring us eggs and meat, and will also produce a lot of farms that pollute the environment. stool.

In modern agricultural production, in order to reduce the pollution of chemical fertilizers, our use of organic fertilizers is becoming more common.

Production process of cow manure organic fertilizer manufacturing process

Cow dung is a good raw material for processing organic manure, and cow dung contains high nutrient content and properties for crops and soil: cow dung contains 4%, nitrogen is 0.65%, phosphorus is 0.47% , Potassium is 0.23%.

Preparation before use: Before using the machine, the whole machine should be cleaned thoroughly, and the connection between the components and the transmission can be checked. Fermentation stacker is used for fermentation and stacking of organic wastes such as cow dung, livestock and poultry manure, sludge garbage, sugar mill filter sludge, slag cake meal and straw sawdust. Efficacy of fermentation and dehydration in garbage dumps, gardening plots and Agaricus bisporus plantation plots.

Production process of cow manure organic fertilizer: cow manure raw material fermentation → organic manure grinder → horizontal mixer → new organic fertilizer granulator → cow manure dryer → cooling machine → drum screening machine → packaging machine. It can produce compound fertilizers of various concentrations and types (organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.). This equipment shortens the technological process for organic fertilizer and compost production.

The role of cow manure organic fertilizer equipment

How much does it cost to process cow manure into organic fertilizer? It is a large beef cattle breeding county. In the past, it did not pay enough attention to the treatment of cow dung. There were basically no cow dung treatment facilities. 99% of cow dung was in a state of accumulation, which not only occupied a lot of land, but also polluted the environment. In response to this situation, the Hengdu Beef Cattle Farm in Jianguo Village, Gaojia Town, the county introduced an enterprise “park” to process cow dung into organic fertilizer, using new technologies such as rapid continuous fermentation and agricultural waste microbial complex bacteria to achieve Zero emissions of pollutants.

In the production workshop of the enterprise, cow dung is packaged into organic fertilizer in bags after the process of adding bacteria, stirring and fermentation, drying and cooling. It is reported that companies that use cow dung to produce organic fertilizer like this have already introduced four.

According to the relevant person in charge of Hengdu Beef Cattle Farm, the cow dung produced on the farm is separated from wet and dry, and the manure is used to produce organic fertilizer, which can be sold for 600 yuan per ton. The use of cow dung mixed with cow urine to produce biogas, biogas can be used as an energy source for cooking and lighting, truly turning waste into treasure. The pollution problem of beef cattle breeding has been effectively solved.

Advantages of disc granulator in processing agricultural straw to produce fertilizer

At present, the utilization of agricultural straw is very low whether it is returned to the field as fertilizer or as feed, causing serious waste. The development of bioengineering technology makes use of biotechnology to produce bio-organic fertilizer through the biological fermentation of straw, human and livestock manure, which can not only improve crop yield, but also reduce pollution, ecological and environmental protection, and produce green products.

Disc granulator (also known as spherical disk), the granulation disk is of integral arc structure, with high granulation rate. The granulation disk is equipped with three discharge ports, which are convenient for intermittent production operations, reduce labor intensity and improve labor efficiency. The reducer and motor are driven by flexible belt, which can start smoothly, reduce the impact force and improve the service life of the equipment. The bottom of the granulation disk is strengthened by multiple radial steel plates, which are firm and durable without deformation. The thickened, weighted and solid base design, It is an ideal equipment for granulating organic fertilizer and compound fertilizer without fixing with anchor bolts and running smoothly.

The raw meal powder is uniformly wetted by atomized water in the two-shaft mixer to form a ball core with uniform particle size, and then sent to the balling plate for balling. The moisture content of the pellets shall be controlled at 12~14%. Most of the water should be added in the twin-shaft mixer, and only a small amount of make-up water should be added in the disc granulator. The make-up water should be controlled at about 0~3%. The dry powder granulation is directly added to the pelletizing plate and sprayed with appropriate water. After entering the pelletizing plate, the raw material ball core moves along the parabola under the action of centrifugal force, friction and gravity.

Due to the cohesiveness and plasticity of the material, the ball and core bond with each other and grow up gradually in the process of movement. When the parameters of the disc granulator such as inclination angle, disc edge height, rotating speed and moisture are specific, the pellets with different particle sizes roll downward from the disc edge at different separation angles due to different gravity. In the continuous rolling process, the water in the ball is continuously drained out of the surface. Due to the cohesiveness of the material and the natural volatilization of the liquid film on the surface, the ball has strength and is discharged from the edge of the disk with the rotation of the tilting disk.

The fermentation fertilizer manufacturing process of organic compost can be simply divided into the following four stages:

(1) Fever stage In the early stage of composting, the microorganisms in the compost are mainly of moderate temperature and aerobic types. The more common ones are non-spore-forming bacteria, spore-forming bacteria and mold. They start the fermentation process of composting. Under aerobic conditions, they vigorously decompose and easily decompose organic substances (such as simple sugars, starches, proteins, etc.) to generate a lot of heat. For the fever stage, or the middle temperature stage.

(2) High temperature stage As the temperature increases, the heat-bearing microorganisms gradually replace the mesophilic species and play a leading role. The temperature continues to rise, generally reaching more than 50 ° C within a few days, and enters the high temperature stage. In the high temperature stage, thermophilic actinomycetes and thermophilic fungi become the main species. They strongly decompose complex organic substances (such as cellulose, hemicellulose, pectin substances, etc.) in the compost, heat accumulation, the temperature of the compost rises to 60-70 ° C, and even up to 80 ° C. Then most of the good heat Microorganisms also die in large numbers or enter a dormant state (more than 20 days), which has an important role in accelerating the compost maturation. Improperly composted compost only has a short high temperature period, or does not reach high temperature at all, so it matures slowly, and it cannot reach a semi-mature state in half a year or more.

(3) Cooling stage When the high temperature stage lasts for a certain period of time, most of the cellulose, hemicellulose and pectin substances have been decomposed, leaving complex components that are difficult to decompose (such as lignin) and newly formed humus Activity weakens and the temperature gradually decreases. When the temperature drops below 40 ° C, the mesophilic microorganisms become the dominant species again. If the temperature comes down early, it indicates that the stacking conditions are not ideal and the plant matter is not decomposed sufficiently. At this time, the pile can be turned over, and the accumulated materials can be mixed well to generate a second heat and temperature increase to promote the composting of the compost.

(4) Stage of maturing and composting After composting, the volume of the compost is reduced, and the temperature of the compost is reduced to slightly higher than the temperature. At this time, the compost should be compacted, causing an anaerobic state, and weakening the mineralization of organic matter, so as to facilitate fertilizer preservation.

In short, the fermentation process of organic compost is actually the process of metabolism and reproduction of various microorganisms. The metabolic process of microorganisms is the process of decomposition of organic matter. The decomposition of organic matter will inevitably produce energy, which drives the composting process, raises the temperature, and at the same time dries the wet substrate. Many composting substrates carry human and animal and plant pathogens, as well as annoying organisms such as weed seeds.

During the composting process, by continuously heating for a short time, the growth of these organisms can be effectively controlled. Therefore, a major advantage of high-temperature composting is its ability to inactivate human and animal and plant pathogens and seeds. Pathogens and seeds are inactivated due to cell death, and cell death is largely based on the thermal inactivation of enzymes. At an appropriate temperature, the enzyme inactivation is reversible, but at high temperatures it is irreversible. Within a very small temperature range, the active part of the enzyme will rapidly decrease. If there is no enzyme, the cell will lose its function and die. Only a few enzymes can withstand the long-term high temperature. Therefore, microorganisms are very sensitive to heat inactivation.

Studies have shown that heating at a certain temperature for a period of time can destroy pathogens or annoying organisms. It is usually heated at 60-70 ° C (damp heat) for 5-10 minutes. Can destroy the activity of non-spore bacteria and non-dormant bodies of spore bacteria. Using heat sterilization, heating at 70 ° C for 30min can eliminate pathogens in sludge. However, at lower temperatures (50-60 ° C), some pathogens can survive up to 60 days. Therefore, it is necessary to maintain a temperature above 60 ° C for a period of time during the composting process. During the composting process, the pile should be turned over if necessary. Generally, it takes place when the reactor temperature crosses the peak and begins to cool down. Turning the reactor can remix the materials with different decomposition temperatures in the inner and outer layers. If the humidity is not enough, some water can be added to promote the compost to rot evenly.

The lees has a large acidity and a moisture content of more than 65%. It is highly biochemical, easily corrupted, and inconvenient to store. If not handled in time, it will easily cause great pollution to the environment. On the other hand, lees, as a by-product of the production of liquor, is rich in nutrients such as crude protein, crude fat, crude starch, crude fiber and nitrogen-free leachate, and is also rich in inorganic elements such as phosphorus and potassium as well as pentose and total sugar. Ingredients are an excellent source of organic fertilizer manufacturing process. The use of rich lees raw materials to make organic fertilizers can not only solve environmental problems, turn waste into treasure, but also provide an organic environment for green agricultural production. It has high economic, environmental and social benefits.

The amount of lees is evenly sprinkled with 2 to 2.5% of lees quality quick lime, 3 to 5% of straw and 1 to 2% of sawn wood surface, and the fermentation material is prepared by mixing evenly. Spread the strains evenly on the prepared fermented material at a ratio of 0.2% to 0.3% of vinasse quality and ferment for 3 to 5 days. The temperature of the stack rises to 60 to 65 ° C and the stack is covered with mycelia.After 2 ~ 3 days, the temperature of the stack will rise to 60 ~ 65 ° C again, covered with mycelium, then turn over again; after 8 ~ 10 days of fermentation, enter the high temperature period of fermentation to maintain the temperature of the stack Do not exceed 65 ° C to adjust the frequency of turning over; the fermentation cycle is 20-25 days. The temperature of the stack fell below 50 ° C, the moisture of the compost was about 35%, the appearance was brown, gray-brown or black, the physical structure was loose, and there was no foul odor. Crushing and sieving: After passing through the maturation period, the fermented materials are crushed with a semi-humid material crusher, and then screened through a 3 ~ 4mm roller screen to obtain the final product of lees organic fertilizer.

Distillery distillery + fermentation agent + auxiliary raw materials (crop straw, etc.) → pre-mixing → fermentation tank → turning machine → fermentation (7-8 days rot, dehydration, sterilization, deodorization) → out of the pool → powdered organic fertilizer (Or as a raw material for granulation and deep processing to produce round granulated organic fertilizer) → Ingredients measurement → multidimensional mixing → extrusion granulation → polishing and shaping (3.5-4mm round spherical granules) → low temperature drying → normal temperature cooling → graded screening → finished organic fertilizer → Measuring and packaging

The role of organic fertilizer pulverizer in the treatment of poultry and livestock manure

After several years of structural adjustment, the animal husbandry industry has become the main industry, and the production base based on pigs, poultry and meat cattle and sheep is being formed. At the same time, the ecological and environmental problems are also becoming more and more serious. Using livestock manure to produce bio-organic fertilizer can not only alleviate the shortage of fertilizer resources, improve soil fertility, improve crop quality and yield, but also achieve cleaner production and recycling of agricultural resources, and promote the healthy development of ecological agriculture construction. It has significant ecological and environmental benefits, social benefits and economic benefits.

The working principle of the organic fertilizer pulverizer: the material enters from the feed inlet and collides with the high-speed rotating shell in the organic fertilizer pulverizer shell. After the impact, the material is squeezed and broken, and then hit the inner wall of the shell and collides with the hammer head. In this way, during the process of falling, it will change into powder or particles less than 3mm after several impacts, and discharged from the lower screen plate. The particles with large particle size cannot be discharged from the screen plate, and continue to be broken by the hammer, Until the sieve plate is discharged.

The organic fertilizer pulverizer is suitable for fermenting decomposed animal manure, straw, straw, urban domestic garbage, Chinese herbal residue, distiller’s grains, corn cob, sludge, sugar cane residue, biogas residue and other dry and wet raw materials with good effect. It can grind hard materials such as glass, ceramics, bricks and crushed stones in municipal solid waste and sludge organic fertilizer. This machine solves the problem of crushing high water content organic matter.

Straw organic fertilizer made by organic fertilizer crusher can show the long-term effect of inorganic fertilizer, organic fertilizer and biological fertilizer activity. So straw organic fertilizer is an ideal soil conditioner, nutrient supplement and ecological balance agent.

The fertilizer production line is to be designed and used to produce the npk compound fertilizer and organic fertilizer.So how many process is to be designed by the fertilizer machine manufacturers?The npk fertilizer production line is to be designed for producing the npk fertilizer,so there we share the npk fertilizer manufacturing process in this article.
1.Compounding process:The operator shall add various raw materials such as N,P,K and additives to the elettronic belt weigher in strict accordance with the requirement of the technician of each kind of raw material addition amount.The addition process of raw materials requires that the raw materials shall be powder or granular without caking,and the materials flow shall be uniform,and the operation shall not be interrupted from time to time.
2.Comminution process of compound fertizer:Accprding to the design requirements,the mixed fertilizer is transported to the raw material crusher for raw material crushing,the purpose is to crush all kinds of raw materials to a certain fineness,basically making the particle size of raw materials less than 1mm,which is conducive to the rolling of materials into standard balls in the granulator.

3.Granulation process of compound fertilizer:In the npk fertilizer production line,it is to be equipped with different type and series fertilizer machine to finish different production process.The crushed raw materials enter the conveyor of the belt conveyor and are transported to the fertilizer granulator machine of the rotary drum granulator for granulation.The solid fertilizer powder that needs to be granulated rises with the help of the rotation of the cylinder,and rolls down under the action of gravity.At the same time,granulate according to the amount of raw materials and the proportion of binder.The materials are wrapped on the surface of nucleation layer by layer,and thicken layer by layer.
Gradually granulating,under the action of the above forces,the material gradually forms the base core until it reaches the granulation requirements and enters the drying section.
4.Drying process of compound fertilizer:The dryer adopts the method of cylinder edge transmission,flange connection and direct heat transfer,which is suitable for the drying of compound fertilizer after granulation.The materials to be dried enter the drying area of the board with special combination.Due to the tilting movement of the body and the board,the materials are continuously taken up by the board to be fully scattered and moved longitudinally.
At the same time,it can fully exchange heat with the high temperature furnace gas from the hot blast furnace,evaporate water and dry the materials.Materials and flue gas need to be dried and operated in a downstream and micro negative pressure way.
5.Cooling process of compound fertilizer:The rotary cooler is mainly used for the cooling of compound fertilizer products after drying.It can directly cool the hot granular material fertilizer to near normal temperature.The material entering the cooler moves forward continuously under the rotating and tilting action of the body.At the same time,the induced draft fan from the tail of the cooler to the head meets the material countercurrent,taking away the heat of the material.
In the process of cooling,the cold wind also takes part of the water.
The cooled materials are easy to be packed in time and quickly to prevent caking during storgae.The machine adopts micro negative pressure operation,which reduces pollution and improves working environment.It has the characteristics of reasonable structure,stable operation and strong adaptability.The cooled materials are transported to the sixth sectionn by belt conveyor.
6.Screening and large particle crushing process of compound fertilizer:Screening section is mainly to separate fine powder,finished product and large particle materials.First,the fine powder in the semi-finished produce is separated,and then the large particles are separated.
The separated large particles are crushed by the large particle curhser,and then enter the return belt together with the separated fine powder,and return the granulator for granulation.Finished products enter the seventh section.
7.Packaging process of compound fertilizer:The finished products is lifted to the bin on the packaging machine by the leather elevator,unloaded to the weighing scale body and carried out the automatic weighing peration according to the set weigning weight.The weighed material enters the sewing bag section through the conveyor,and then the sewing bag operation is carried out and put into the finished product warehouse.
Besides the npk fertilizer production line is to be designed for producing the npk,compound fertilizer,the organic fertilizer production line is also to be designed for producing the organic fertilizer.In the fertilizer manufacturing process,when producing the organic fertilizer by using the complete fertilizer production line and fertilizer machine to finish the production process,it improves the working efficient,at the same time,it also saves more labor cost.
