Why is the dryer often used to treat fertilizer in the production of cow manure organic fertilizer

Written by fertilizer production line on January 7th, 2023.

Poultry manure is increasingly polluting the environment. However, cow manure is rich in nutrients and trace elements and is a good organic fertilizer. The fertilizer production line develops cow dung as a compound organic fertilizer, which can not only turn waste into treasure, but also reduce environmental pollution and prevent the spread of diseases, which has good economic and social benefits.

Our fertilizer granulator machine price is low, and the dryer is of high quality and low price. There is a section of secondary granulation area at the front of the dryer, and the material can realize secondary granulation in this section. Then the material is lifted up by the lifting plate to fully dry the material. The tail of the dryer draws out the moist hot air through the pipe through the exhaust fan, and enters the settling chamber to settle. After passing through the settling, the exhaust gas passes through the washing tower to spray dust and spray water. It is pumped out by a water pump for recycling, and after the second dust reduction treatment, the exhaust gas is discharged into the atmosphere through the chimney.

The main features of the dryer machine are as follows

1. Cow dung dryer has high degree of mechanization, large production capacity and continuous operation.

2. The organic fertilizer machine has an excellent and simple structure, and the material runs smoothly through the resistance of the cylinder and is easy to operate.

3. The cow dung dryer has fewer failures, low maintenance costs and low power consumption.

4. Wide application range and good product drying uniformity.

5. Sterilization and deodorization can be achieved while drying.

How to Solve the Problem of Material Agglomeration in Organic Fertilizer Fermentation

Written by fertilizer production line on January 7th, 2023.

Use a compost turning machine to process fermented materials. During the composting process, technologies such as adjusting the carbon to nitrogen ratio, controlling the stack temperature, ventilation and moisture can be used to deodorize. The animal manure treatment in the farm has been mechanized, which solves the environmental pollution problem caused by the farm. The fertilizer granulator processes the compost and obtains more benefits.

In water management, if there is less water, the frequency can be reduced to prevent the slow down of fermentation speed and the decrease of microbial activity. If the turning frequency of the compost turning machine is high, the fermentation facilities can be closed to reduce heat dissipation, or the outer wall of the fermentation facilities can be built with insulation materials to maintain the temperature, or other heat sources can be used to heat up to prevent the temperature drop.

Caking of fermentation materials: there are large parts of fermentation materials in the heap, and the structure is inconsistent.

Possible causes and solutions:

1. The raw materials are not mixed evenly or the compost turning machine is not enough. Improve the original mixing method.

2. Uneven air flow or insufficient air circulation: sorting or crushing compost to improve air distribution.

What are the advantages of chicken manure organic fertilizer production line in processing fertilizer

Written by fertilizer production line on January 7th, 2023.

At present, the actual utilization rate of chemical fertilizer in China is only 30% – 45%, even lower in some regions! After the application of organic fertilizer, the beneficial biological activity improves the soil structure, increases the soil water and fertilizer conservation capacity, thus reducing nutrient loss, and increasing the effective utilization rate of chemical fertilizer to more than 50%. It can also reduce the amount of chemical fertilizer and the cost of fertilization. Since the 1970s and 1980s, the UK, France and Japan have reduced the use of pesticides and fertilizers. Organic fertilizer is the main fertilizer. The use of chemical fertilizers and pesticides has been greatly reduced. The grain output has increased and the quality is much better than before. Therefore, the fertilization method of “giving priority to organic fertilizer, supplemented by chemical fertilizer” is a reasonable fertilization method at present!

How to Make Animal Manure into Fertilizer by Organic Fertilizer Granulator

Written by fertilizer production line on January 7th, 2023.

Taking into account the use of efficient fertilizers and chemical pesticides, the continuous decline of organic content in soil, and the bleak situation of soil sales, crop yield, and low quality, the entire engineering and technical personnel and experts and professors of the Academy of Agricultural Sciences have developed a bio fertilizer granulator with chicken manure, pig manure, humic acid, and wastes with high organic content as the main raw materials through repeated tests, making contributions to the healthy development of agriculture.

1: Fermentation. The main function of the fermentation part of the organic fertilizer production line is to reduce the water content in the organic fertilizer raw materials at an early stage. The raw materials of organic fertilizers are mainly chicken manure, pig manure, sheep manure and other animal manure, cow manure and sheep manure, but the humidity of chicken manure and pig manure is too high. In particular, the initial humidity of chicken manure and pig manure is generally above. It is impossible to handle such high humidity in person. It must go through the fermentation tank. Generally, the humidity of fresh chicken manure can be reduced to below by fermenting for about a week. In addition, during the fermentation of chicken manure, crude fiber materials such as bran and bran are mixed together, which tells you the key to shorten the fermentation time and reduce the cost.

2: Broken part. The feces of fermented animals are gathered together, and the massive materials are not directly dried, so it is better to use a small crusher to crush them first, and then enter the next stage. In organic fertilizer equipment, the crushing part is often essential.

3: Drying part. Here, some friends will ask how to dry again instead of fermenting. Otherwise, the fermentation can only adjust the humidity. In fact, to make organic particles, water must be below, so the drying process is also necessary.

4: Granular part. Organic fertilizer granulator is the key link of the whole organic fertilizer production line. In general, it is recommended to use the combination of pelletizer ball shaping machine for particle function, rather than traditional pelletizer ball shaping machine. The advantages of this method are high particle forming rate and good density.

5: Cooling, packaging and linking. Cooling and packaging can be ignored by a small number of production users. Users with small amount of production can dry by themselves, and only need to pack bags manually. The automatic packing machine only needs a large number of organic fertilizer production lines. The fertilizer produced by organic fertilizer equipment is an ideal fertilizer for saving agricultural production investment, improving soil fertility, increasing yield, optimizing crop quality and promoting green food and green agriculture.

How to use organic fertilizer composter reasonably and efficiently

Written by fertilizer production line on January 7th, 2023.

In organic fertilizer fermentation, livestock manure and other materials, domestic waste, sludge and other fertilizer making base materials should be piled on the flat ground in a choppy manner. When the tank turning machine is used to ferment organic fertilizer, the material is directly put into the fermentation tank. In the fermentation process, compost turning function is used to provide the quality of organic manure fermentation.

Organic fertilizer raw material processing and fermentation skills

(1) Ferment with weeds and crop straws (it will decompose in about 25 days):

Use crushed weeds and crop straws (generally 3-5 cm in length), which can be adjusted with 40% manure or biogas slurry; 2% urea (46% nitrogen) or equal nitrogen fertilizer can also be used Compound fertilizer can be adjusted; it can also be adjusted by adding fresh livestock and poultry manure at a weight ratio of 3:1-4:1. The decomposed compost is processed by the rotary drum granulator to produce different kinds of compound fertilizers.

(2) Fermentation with pure feces (it will decompose in about 20 days):

Mixing is to fully mix livestock and poultry manure with high moisture content with auxiliary materials and high-temperature biological fermentation bacteria in a certain proportion to reach fermentation conditions. Organic wastes such as livestock manure can be fermented directly. The purpose of mixing is to achieve high-temperature aerobic fermentation conditions through mixing, and to make the materials have good permeability. The high-temperature aerobic trough compost turning machine has a good effect on the treatment of organic fertilizer, and all the raw materials are mixed evenly during the fermentation process.

(3) Fermentation with manure (it will decompose in about 15 days):

After expanding the volume of bacteria directly, remove a layer in the enclosure evenly, stir it, and stack it directly on the fermentation tank. Repeat the operation. If the water content is too large, add appropriate amount of broken dry auxiliary materials into the enclosure to adjust. The decomposed compost is further processed with an organic fertilizer granulator machine.

(2) Regularly clean up the iron impurities on the permanent magnet cylinder and the permanent magnet plate of the feeder of the pulverizer;

(3) Regularly check the fineness of the crushed products to ensure that the materials are suitable for the rotary drum granulator.

(4) Clean or replace the bag of the dust collector regularly (ensure the air permeability of the bag), and regularly check the working condition of the solenoid valve (to see if it can work normally);

(5) Regularly check the wearing condition of each vulnerable part of the pulverizer to see if it belongs to normal wear;

(6) Always pay attention to the vibration of the crusher;

(7) When the hammer piece of the pulverizer is seriously worn and needs to be replaced, it is necessary to weigh it to ensure that the weight difference between the two opposite hammer pieces on the two relative hammer pin shafts is ≤ 1g, and the total weight difference of the hammer pieces on the two relative hammer pin shafts is ≤ 2G;

(8) When installing the screen, pay attention to whether the screen is properly worn and installed, and whether the screen needs to be replaced properly;

(9) The opening degree of the air supply door of the impeller feeder should be adjusted appropriately;

(10) If abnormal conditions such as large vibration and high noise of the crusher are found, it should be shut down immediately for inspection;

(11) 80 grams of grease should be added to the spindle bearing after every 40 hours of operation, but only to 60%. After 1800 hours of operation, the bearing box cover should be removed and all used grease should be replaced. When changing to fresh grease, add grease to the area around the rollers and bearing rings, and add 1/3 to 1/2 of the grease to the bottom case. Do not add too much grease;

(12) When it is found that the output of the grinder suddenly drops, in addition to the factors of raw materials, check whether the air supply door is in place, whether the pipeline is leaking, whether the pulse bag is blocked, whether the solenoid valve, fan is working normally, etc.
