How To Make Organic Fertilizer From Pig Manure?

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.

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.


How To Turn Your Poultry Manure Into Organic Fertilizer?

The Ideal Design For Any Bio Fertilizer Production Line

An organic fertilizer production line could be helpful if you own one. Should you be constantly purchasing fertilizer for your crops, producing your very own might be a better solution. You can utilize existing organic materials on the farm to manufacture fertilizer. This may range from manure that you may have composted throughout the year. As long as you have got a production line that is designed to produce plenty of this material, you save money by performing it yourself. It’s important to experience a production line that is designed for maximum output. Is a review of the best design designed for an organic fertilizer production line.

What Will You Discover On These Production Lines?

Many of these will contain many different components which will function in tandem together. This typically starts with adding the fertilizer on the fertilizer manufacturing machine through which it will probably be converted into pellets. There might be an area the location where the material will be sorted, shredded, and subsequently prepared. The compost, which will have already transformed into fertilizer, will be screened just before this conversion process. Mixing the fertilizer with many other materials may be needed to ensure the pellets to create. Once they have been solidified, it is possible to bag them, sell them, or utilize them for your own fertilizer manufacturing business plan.

Why Is It Vital That You Have Your Very Own Fertilizer Production Line?

It is important for larger firms that grow a substantial quantity of crops to get access to a fertilizer production line. Should you be acquiring the fertilizer from other companies, you will be likely paying excessive, particularly if have manure you could convert into fertilizer. Even though initial expense of these systems will be extremely high, they are going to greater than buy themselves throughout a few years. Furthermore, it gives you the opportunity to control the consistency in the fertilizer you are producing. Every one of these benefits can be yours if one makes this sort of investment.

The Most Effective Design To Get A Bio Fertilizer Production Line

The ideal design begins with a conveyor belt system. It is going to send the fabric into a crusher. From that point, it would move through a bucket elevator into the disc granulator. This may spin the content at maximum speed. As the pellets are designed, they will likely then be shipped to a drying machine. After that, they may enter a cooling machine, a grading screen component, and subsequently can be packaged or stored. When you have a fertilizer production line which utilizes most of these components, it will likely be highly efficient.

This summary of some great benefits of owning an organic fertilizer production line should assist you in making the proper decision. By comparing different firms that sell them, you will be able to purchase the best one. Once it is actually fully operational, you can produce an incredible number of fertilizer pellets. It is possible to sell many of them, but in most cases, you will probably use them for your own personal crops. It’s one of the most cost-effective approach to produce fertilizer pellets which you can use to enhance the crops that you grow annually.

How does the Screw Fertilizer Conveying Machine Work?

Screw fertilizer conveyor is the most economical and space saving solution for conveying powder or granular fertilizer from low position to high position. When discharging bulk materials from silos and hoppers, conveying or feeding equipment may be discharged vertically into a  weighing hopper, one or more multiphase bins or silos, or other conveyors or conveying systems.

The rotating spiral blade moves the material and carries on the screw conveyor transportation. The force that makes the material not rotate with the screw conveyor blade is the material weight and the friction resistance of the screw conveyor shell to the material.

For spiral blades welded on the rotating shaft of screw conveyor, the surface types of blades include solid surface, belt surface, blade surface, etc. A thrust bearing is provided at the end of the screw shaft of the screw conveyor in the direction of material movement to give the axial reaction force to the screw along with the material.

When the length of the machine is long, the middle hanging bearing should be added. Screw conveyor is generally composed of conveyor body, material inlet and outlet and driving device; screw blade of screw conveyor has three forms: solid spiral surface, belt type spiral surface and blade spiral surface. Among them, blade type spiral surface is relatively less used, mainly used for conveying materials with high viscosity and compressibility.

This type of screw suspension surface, in the process of completing the conveying operation, is the same with and complete the material mixing and other functions. Compared with other conveying equipment, screw conveyor has the advantages of small cross-section, good sealing performance, stable and reliable operation, multi-point loading and unloading, safe operation and easy maintenance.
