Npk fertilizer production line needs packaging machine to prevent fertilizer particles from caking

by organic fertilizer production line
Specialized fertilizer production line equipment coating machine can prevent fertilizer caking. Huaqiang coating machine is composed of screw conveyor, mixing tank, oil pump, main engine, etc. It adopts powder powder spraying or liquid coating technology. If you want to produce organic fertilizer, NPK compound fertilizer and inorganic fertilizer, you can choose the coating machine produced by our factory. The coating effect is better than preservation, and the production capacity can reach 2-45 tons per hour.

Rotary coating machine is a kind of equipment designed to solve the problem of stacking, rewetting and agglomeration of granular fertilizer. The fertilizer coating machine uses a special liquid raw material or a spraying process combined with solid powder. After the fertilizer is made into granules by the rotary drum granulator, the coating machine forms a protective film on the surface of the granules to isolate it from the outside air, thereby effectively preventing the salt bridge effect and moisture absorption on the surface of the fertilizer, and also improving the surface brightness of the granules. And some trace elements can be appropriately added during the processing to improve fertilizer efficiency.
The processing of the coating machine can prolong the function of the fertilizer in the soil and effectively improve the application effect of NPK fertilizer. Polypropylene lining is used in the main engine, which is corrosion resistant and durable. When the finished product particles uniformly flow into the rotating coating machine in the NPK production line and roll continuously, the prepared oil like mixed coating agent is sprayed into the surface of the particles with the help of compressed air and nozzle, so that a uniform protective film is coated on the surface of the particles.
There are many types of fertilizer coating machines, which can be customized according to customer requirements, and the general construction period is about 10 days. Equipment cost-effective, customers can come to our factory to visit the test machine, looking forward to win-win cooperation with you.

How to select suitable dryer in npk fertilizer production line

by organic fertilizer production line

In the production process of bio organic fertilizer, the moisture content of fertilizer is required to be lower than 14%. If the particles are too wet, they need to be dried. Therefore, drying is an indispensable and important process in the fertilizer production line, which directly affects the output, quality and energy consumption. It is very important to select the fertilizer granule dryer machine reasonably.

In the fertilizer production process, the fertilizer processed by the rotary drum granulator enters the dryer for drying. In order to avoid the death of effective live bacteria due to high temperature in the drying process, the temperature of hot air contacting with materials is different according to the moisture content of materials. It is suggested that the hot air temperature can be controlled in sections, which can improve the thermal efficiency and avoid the death of effective living bacteria.
Combined with these characteristics, a drum dryer suitable for low temperature and low moisture drying is selected, which can control the temperature of hot air to ensure that the material temperature is not higher than the specified temperature in the whole drying process. A cooler can be added at the tail of the machine, which can be cooled immediately after drying, which has the function of multi-purpose.

 

A section of secondary granulation area is set in the front of the rotary drum dryer for fertilizer, in which the material can realize secondary granulation. After that, the material is lifted up by the lifting plate for full drying. The wet hot air is drawn out through the exhaust fan through the pipeline at the tail of the dryer, and then enters the settling chamber for settlement. After the secondary dust reduction treatment, the tail gas of NPK production line can be discharged into the atmosphere.

How much profit can be gained from processing fertilizer with sheep manure organic fertilizer production line

by organic fertilizer production line

Organic fertilizer can improve the utilization rate of fertilizer in the soil. The main raw material of organic fertilizer is animal manure. They include: pig, cow, chicken, sheep, etc. There are many advantages in using sheep manure to produce organic fertilizer.

Raw material analysis of sheep manure organic fertilizer

Nutrition analysis: 24% – 27% organic matter content, 0.7% nitrogen content to 0.8%, 0.45% to 0.6% and 0.3% potassium content to 0.6%, organic matter sheep urine 5% content, 1.3% to 1.4% phosphorus content, nitrogen content is extremely low, very rich in potassium, as high as 2.1% to 2.3%
Character analysis: Sheep are ruminants, but they rarely drink water, so the stool is dry and thin, and the stool volume is very small. Sheep manure is a kind of thermal fertilizer between horse manure and cow manure.
Sheep excreta and urine are rich in nutrients, which can not only easily decompose the effective nutrients absorbed by crops, but also have the late nutrients that are not easy to decompose. It is a good fertilizer that combines the efficiency and speed of fertilization. The decomposed sheep manure treated by the compost turning machine is suitable for the application of various soils.

Technology of sheep manure organic fertilizer production line

Sheep manure was composted and fermented by high-temperature fermentation bacteria, straw was crushed, and the materials were mixed with biological compound bacteria, and the compost turner was used for regular composting. The decomposed organic matter can be directly made into powder fertilizer or further processed. Sheep manure compost as a part of raw materials, mixed with inorganic fertilizer according to the formula, can be called high efficiency organic fertilizer after NPK production line processing.

 

Special reminder: all animal manure must be put into the ground through harmless fermented fertilizer before use. Because the raw fertilizer contains a variety of harmful bacteria, it will breed diseases and insect pests, damage soil health, thus affecting the healthy growth of crops.
In short, organic fertilizer is a kind of green and harmless soil fertilizer, and it is the mainstream of future agricultural development. It is recommended that we do not use chemical fertilizers in a single organic fertilizer for the best results.

How to choose the screen of the drum screen in npk fertilizer production line?

by organic fertilizer production line

Drum screening machine is also widely used in fertilizer production industry. Both the powder and the granule processed by the fertilizer granulator should be screened by the roller screen.

The screen selection of drum screening machine is related to the efficiency of the equipment and the service life of the screen, so the selection of the screen is also more important in the fertilizer machine.
The screen mesh of the drum screening machine is generally selected as manganese steel woven mesh, stainless steel woven mesh, and manganese steel woven mesh is generally recommended. In addition, the selection process is also related to the particle size of the screened material. For example, the size of the screen hole should consider the particle size made by the rotary drum granulator.
The material size is generally between 10mm-200mm, using manganese steel woven mesh. The sieved material whose particle size is between 200 mesh and 300 mesh adopts stainless steel woven mesh. When the screen is too small, it is generally necessary to install a lining screen, to protect the working screen, and secondly to play a supporting role to extend the life of the working screen.

Fermentation method of composter in chicken manure organic fertilizer production line

by organic fertilizer production line

In the production of livestock manure fertilizer production line, the key equipment is the organic fertilizer turning machine. The materials and the composition of the main parts have a very important impact on the processing of livestock manure. Here is a brief introduction to the compost fermentation program of the organic fertilizer turning machine.

Fermentation scheme of organic fertilizer compost turning machine:

1. First, pile chicken manure or other animal manure, domestic waste and other fertilizer base materials on a flat ground in strips: the width of pile is equal to the width of equipment, the height is as high as possible, and the length is as long as possible, such as 100m, 50m, etc. if the site is feasible; the ground should be flat, cement, brick, and land can be used (as long as it is flat and has a certain hardness). The production of 10000 tons of fertilizer is required The area is 5-6 mu.
2. Add the piled chicken manure (other livestock manure or domestic garbage) to the biological starter (strain), 1 kg of starter (strain) per ton of fertilizer base material.
3. Use a compost turning machine to ferment straw and chicken manure (pig, cattle, sheep and other livestock manure, filter mud, sludge, domestic garbage, and other agricultural and animal husbandry organic solid waste, the water content should be 50%-70%), and fermentation Mix and stir evenly. It can be deodorized in 3-5 hours, and the temperature is increased to 50 degrees in 16 hours, and when the temperature reaches 60-65 degrees, it will be turned over again to increase oxygen. In the future, whenever the temperature in the pile reaches 60℃-65℃, the pile will be turned over to achieve the effect of uniform fermentation, aeration, and cooling, and repeat the last process until it is ripe.
4. If the water content of chicken manure is too high, you can use the method of reflux to put the last dry fertilizer on the bottom to form a strip, put the chicken manure in the middle, so that the water on the top is soaked to the bottom, and then turn.
5. Generally, it takes 7-10 days to fertilize. The decomposed compost is processed again by granulator. The fertilizer granulator machine price is low, and the machine is stable and durable.
