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.

How to ferment domestic waste with chain plate composter

Garbage is a very common thing in people’s lives, such as leftovers from farmers’ markets, dead branches and leaves in urban parks, various animal excrement, various straws, etc. These things are low in price and have even brought many negative effects on our living environment. But you know what? Garbage can also be made into organic fertilizer. We can make full use of these “garbage” and ferment them into organic fertilizer with fertilizer fermenter.

The chain-plate tipper is a trough-type aerobic compost fermentation tipper that integrates the functions of tipper and material transfer. Its shape is similar to that of a mobile chain conveyor, which uses multi-tooth chain plates to break up and transport materials. During the continuous transportation and transfer of materials, loose materials fully contact with air to complete the whole fermentation process.

Principle of chain-plate stacker

In the process of tipping, the chain-plate tipping machine moves forward slowly. Its multiple-tooth chain plate disperses the bottom material and sends it away. The upper material will fall onto the inclined conveyor scraper continuously. The material will be broken up and mixed during the conveying process, and fall into the groove after turning over the conveying head, thus forming a quantitative displacement. As the tipper continues to move forward, the materials form a regular and equidistant backward movement in the tank, making each tipper uniform and thorough.

Characteristics of plate tipper

1. The chain plate mechanism with chain drive and rolling support is adopted, which has low overturning resistance and low power consumption, and is suitable for deep groove operation.

2. The material will stay on the scraper for a long time when it is turned over, and it will be scattered at a high level, fully contacted with the air, and easy to reduce the moisture content.

3. The lifting of the chain plate of the tipper is controlled by the hydraulic system, which is flexible, safe and fast.

4. The machine can be remotely controlled to advance, overturn, lift and retreat and improve the operating environment.

5. It is equipped with a tank car to change the tank, which can realize the multi-tank operation of a stacker.

The drying link is an important link in the fertilizers manufacturing process, and the method of drying is critical. The fertilizer produced by the organic fertilizer equipment is completely dry fertilizer, so how does the organic fertilizer equipment produce dry fertilizer?

(1) Mechanical dehydration method: The mechanical dehydration method is to squeeze out part of the water by pressurizing the material. Commonly used methods include squeezing, sedimentation, filtration, and centrifugal separation. The mechanical dehydration method can only remove part of the free water in the material, and the combined moisture remains in the material. Therefore, the water content of the material after mechanical dehydration is still very high, generally 40-60%. But mechanical dehydration is an economical method.

(2) Heating and drying method: also known as drying, it uses heat energy to heat materials and vaporize the moisture in the materials. It takes a certain amount of heat to remove moisture from the material. Normally, air is used to dry materials. The air is preheated and sent to the dryer, transferring heat to the material, vaporizing the moisture in the material, forming water vapor, and taking it out of the dryer with the air. After the material is heated and dried, the combined moisture in the material can be removed to achieve the required moisture content of the product or raw material.

(3) Chemical dehumidification method: It uses a hygroscopic agent to remove a small amount of water in gas, liquid, and solid materials. Due to the limited dehumidification ability of the hygroscopic agent, it is only used to remove trace moisture in the material. Therefore, there are few applications in production.

Process flow and granulation range of npk fertilizer production line

The npk fertilizer production line will generally crush the fermentation materials that have completed the secondary aging and stacking process and enter the mixing and mixing system. Before mixing and mixing, according to the formula, N, P, K and other trace elements will be added into the mixing and mixing system to start mixing.

The mixed materials are transported to the granulation system, and the granulation enters the cooling system after passing through the dryer. The materials are screened after reaching the normal temperature. The particles that meet the requirements enter the coating machine to wrap the film and start packaging. The particles that do not meet the requirements are crushed by the pulverizer and then returned to the granulation system to continue granulation.

The npk fertilizer production line has quick effect and good economic benefits, and the complete set of equipment has compact flow layout. It reduces the energy consumption of the equipment, makes the operation of the equipment stable, has no discharge of three wastes, and is convenient for maintenance. Wide adaptability of raw materials, suitable for granulation of compound fertilizer, feed and other raw materials, with high product granulation rate. It can produce compound fertilizers of various concentrations and types (including). Especially the granulation of rare earth and ammonium bicarbonate series compound fertilizers.

1. The npk fertilizer production line Applicability of raw materials and its wide range: it is applicable to the direct granulation of fermented livestock and poultry excrement, filter sludge from sugar factories, municipal sludge, paper sludge, distiller’s grains, straw, peat and other organic wastes, and can produce pure organic fertilizer, organic-inorganic fertilizer and bio-organic fertilizer with spherical particles.

2. High balling rate and biological bacteria survival rate: the new technology can make the balling rate high, and the new technology of drying at low temperature and large air volume can make the microbial bacteria survival rate high.

3. The process flow is short and the operation cost is low. The organic raw materials used in this process do not need to be dried, crushed and other preliminary treatment. The process flow is short and the operation cost is low.

Now people pay more and more attention to organic things. Not only the food they eat is organic, but even the fertilizers used in the field are now organic. Using organic fertilizer naturally has its benefits. Pig manure organic fertilizer manufacturing process uses pig manure as raw material, through high-tech equipment fermentation, processing, to produce a series of production equipment for organic manure, the pig manure organic fertilizer produced with it, the role should not be underestimated.

The characteristics of pig manure organic fertilizer:

 Working principle and application scope of organic fertilizer drum dryer

The material enters the inner layer of the rotary drum from the feeding device to realize the downstream drying. The material is continuously picked up and scattered under the inner plate in a spiral way to realize the heat exchange. The material moves to the other end of the inner layer and enters the middle layer for counter-current drying. The material is continuously lifted in the middle layer repeatedly, in a two-step and one-step way. The material in the middle layer not only fully absorbs the heat emitted by the inner drum, but also absorbs the heat of the middle drum, At the same time, the drying time is extended, and the material reaches a good drying state here. The material moves to the other end of the middle layer and falls into the outer layer. The material moves in a rectangular multi-circuit way in the outer drum. The material that has reached the drying effect moves quickly under the action of hot air and is discharged from the drum. The wet material that has not reached the drying effect cannot move quickly because of its own weight. The material is fully dried in this rectangular sheet, thus completing the drying purpose.

The round particles with high moisture content from the organic fertilizer particle shaping section are transported to the feeder of the tubular dryer through the conveyor belt, and the granular materials with chute in the feeder directly enter the rotating drying drum. With the rotation of the drying drum, the granular organic material will be brought up at a certain angle. When installing the drying main pipe and drying branch pipe, the included angle between the main pipe and the horizontal ground coincides with the material picked up. The picked up granular material buries the outlet end of the drying branch pipe, so that the granular material can fully contact with the hot air and prevent heat loss. After the particles are heated, hot water vapor will come up to the upper end of the drying drum. Under the action of high-power induced draft fan for outdoor dust removal and water vapor removal, water vapor dust, etc. will be discharged from the drying device through the air inlet. Finally, the dry organic fertilizer granule material with low moisture is discharged from the material outlet and enters the next cooling section.

Applicable scope of drum dryer:

It is applicable to grains with high water content and high viscosity, such as beer lees, starch lees, rice bran lees, and various residue materials, such as bean dregs, cassava dregs, bean dregs, sweet potato dregs, potato dregs, sugar dregs, fruit dregs, sauce dregs, livestock and poultry excrement, sludge and peat, and other high-moisture materials, and is more suitable for the treatment of livestock and poultry excrement in large, medium and small farms, the production of organic fertilizer from livestock and poultry excrement, compound fertilizer, organic-inorganic compound fertilizer, sludge, grain, food, biogas residue High humidity materials such as medicine residue.

Traditional fermentation organic fertilizer manufacturing process  covers a large area, and the annual output of 30,000 tons of organic fertilizer fermentation area needs about 3,000 square meters, while the use of organic fertilizer fermentation tanks only needs an area of 40 square meters. On the one hand, there is no need to buy so much land On the other hand, it can save the funds needed to build a fermentation shed; the fermentation time is short, the traditional organic fertilizer fermentation takes more than 20 days, and the organic fertilizer fermentation tank can be fermented twice a day, which saves time and improves efficiency. High degree of mechanization, easy operation, traditional organic fertilizer fermentation requires more labor, high labor intensity, organic fertilizer fermentation tank, and humanized design of fermentation tank, one fermentation tank or multiple fermentation tanks can be operated by one person, humic acid fermentation Tank, automatic temperature control, automatic stirring, automatic discharge, automatic feeding; wide adaptability, traditional organic fertilizer fermentation can not be fermented in cold regions in the north and cold regions in winter in the fermentation of organic fertilizers Summer, autumn and winter can be fermented throughout the year.

Advantages of organic fertilizer fermentor:

The whole process has a high degree of automatic automation, strong sealing, and no secondary pollution.

The vertical closed tank structure is adopted, which saves the occupied area, and the fermentation tank better reduces the area requirements for equipment installation.

All parts in contact with feces in the organic fertilizer fermentation tank are made of 304 stainless steel, which is corrosion-resistant and has a long service life.

The operation is fully automated, and the small fermentation tank can realize an unmanned operating system (when the conveyor belt is put in). The inside of the tank is made of polyurethane as a thermal insulation layer, which is less affected by the outside world and ensures fermentation throughout the year.

The organic fertilizer manufacturing process is mainly to screen and magnetically sort the organic waste with a water content of about 30% to 35% after fermentation and decay to prepare round granular organic fertilizer, and add functional bacteria to produce biological organic Fertilizer, adding nitrogen, phosphorus and potassium (total nutrient content less than 15%) can produce organic and inorganic fertilizers.

After the fermented organic waste is subjected to magnetic separation and sieving, the raw materials with binder and other ingredients to be compatible are metered according to the ratio requirements, and then lifted into a multi-dimensional high-efficiency mixer by a bucket elevator for rapid mixing. The mixed material slips out into the mixing bin, and is continuously and uniformly fed into the extrusion granulator by the disc feeder to make cylindrical particles; the cylindrical particles are polished and formed into spherical particles by the circular particle polishing and shaping machine, and are formed by the belt. The machine is fed into the drying, cooling and screening machine (three-in-one model). The particles are dried at a low temperature and large air volume (≤65 ℃) in the front section of the drying and cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling The material enters the screen installed at the end of the cylinder, and the sieved finished particles are transported by the elevator to the finished product silo, which is measured and packaged by the packaging system; the sifted large particles are returned to the mixing granulation system after crushing; The sieved small particles (basically without powder) can be made into small packages and sold directly.

Fertilizer manufacturing process of sheep manure and straw material fertilizer

The amount of sheep dung mixed with the appropriate amount of straw powder depends on the water content of the sheep dung. Generally, the fermentation requires 45% water content, that is, the hands are squeezed into a lump, and the fingers are watered, but there is no dripping. Scattered. Then add cornmeal and strains. The function of cornmeal is to increase sugar content for the fermentation of strains, so that multi-dimensional compound enzyme bacteria will soon have an absolute advantage.

1. Add the prepared mixture to the blender for stirring. The stirring must be even, transparent, and no raw materials are left.

2. The well-stirred ingredients are piled into long strips with a width of 1.5m-2m and a height of 0.8m-1m, and they are tossed once every 2 days with a turning machine.

3. Compost for 2 days, odorless for 4 days, loose for 7 days, become fragrant for 9 days, and become fat for 10 days.

4. The temperature can reach 60 ℃ -80 ℃ on the second day of stacking, killing E. coli, eggs and other diseases and insect pests;

5. On the 4th day, the smell of sheep dung was eliminated; on the 7th day, the compost became loose and dry, covered with white hyphae;

6. On the 9th day, a scent of distiller’s koji is issued;

7. On the 10th day, the bacterial manure will ferment and mature;

8. After a little drying, it can be crushed by a semi-wet material crusher, granulated by an organic fertilizer granulator, dried by a dryer, and then sieved by a sieving machine. The finished organic fertilizer is ready to be installed. The bag is stored.

Matters needing attention during the fermentation of organic fertilizer manufacturing process:

1. Requirements for fermentation raw materials

Fermentation raw materials (such as agricultural wastes such as feces) are preferably fresh without natural recycling.

2. Accessories requirements

Fermentation auxiliary materials (such as straw, rice bran, etc.) should have a moderate water content, strong water absorption, suitable particles or length, and should not be too large. The amount of addition should be determined according to the moisture content of the fermentation raw material.

3. The strains should be removed

Organic fertilizer fermentation strains require at least 50 grams (1 or 2) for one ton of raw materials. Considering that it cannot be evenly spread on the fermentation materials, when using it, first mix 50 grams of strains with 500 grams (1 kg) Stir any kind of raw materials such as wheat drum, sawdust, oil dry, rice bran, etc., and then sprinkle it into the fermentation material, and then stir and pile up the fermentation evenly.

4. The fermentation moisture is adjusted well

The moisture adjustment of raw and auxiliary materials is the most important, which is related to the success or failure of fermentation. Moisture requirements are: after the original accessories are mixed, hold them in a ball and fall on the ground into two pieces. The proportion of general auxiliary materials (such as straw, rice straw, etc.) is 10% to 30% (weight percentage with raw materials). If calculated according to the volume ratio of the two, it is generally 2 parts of raw materials and 1 part of auxiliary materials.

5. The length, width and height of the fermentation stack should meet the standard

It is required that the width of the fermentation product is not less than 1.5 meters, the height is not less than 1 meter, and the length is not limited.
