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

fertilizer granulator Jan 4, 2023

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.

Protection mechanism of belt conveyor in fertilizer production line equipment

fertilizer granulator Jan 4, 2023

In the chemical fertilizer, grain, industrial processing and other industries, we often see such a machine, the material is poured into its bottom, and then with the drive of the belt conveyor, the material is transported to another location, which is very convenient. It is a belt conveyor.

Belt conveyor is widely used in NPK production line of fertilizer industry, which greatly facilitates production and processing. In the design of belt conveyor, the designer also designed the great protection of common problems according to its performance characteristics to ensure the normal operation of the belt conveyor.

1. Belt conveyor speed protection:

If the conveyor fails, such as the motor is burned, the mechanical transmission part is damaged, the belt or chain is broken, the belt slips, etc., the magnetic switch in the accident sensor installed on the driven part of the conveyor cannot be closed or cannot be closed at normal speed . At this time, the control system will function after a certain delay according to the inverse time limit characteristic, and the speed protection circuit will take effect to execute some actions and cut off the power supply of the motor to avoid the expansion of the accident.

2. Temperature protection of belt conveyor:

When the belt conveyor roller and the belt friction cause the temperature to exceed the limit, the detection device (transmitter) installed close to the roller sends out an over-temperature signal. After the receiver receives the signal, a 3s delay is passed to execute some actions and cut off the power supply of the motor , The conveyor stops automatically, which plays a role of temperature protection.

3. Belt conveyor stop protection at any point in the way:

The chemical fertilizer is granulated by rotary drum granulator, and then dried, cooled and screened. Different processing of NPK production line is connected by conveyor. If it is necessary to stop at any point along the conveyor, turn the switch at the corresponding position to the intermediate stop position, and the belt conveyor will stop immediately. When it needs to be re opened, first reset the switch, and then press the signal switch to send a signal.

Operation process of organic fertilizer disc granulator

fertilizer granulator Jan 4, 2023

Control of water content during operation of disc granulator oforganic fertilizer equipment. When the disc granulator is running, the inclined disc granulation process is adopted. The granulation process requires high moisture content, and poor moisture control will lead to the decrease of granulation speed. Therefore, in the process of processing, attention should be paid to the use of spray to observe the moisture control changes of granulating raw materials.
The personnel operating thedisc granulatorshall pay attention to the quality of various materials during the feeding control process to ensure that sundries, large pieces and large particles are not mixed into the feeding. In addition, they should also pay attention to the temperature of the equipment feeding, because if the temperature of the die head is too high, the material is easy to break and stick to the die head after startup. In this case, they should wait for the die head to cool before continuing to operate.
Pay attention to the change of inclination angle of disc granulator during operation. The disc granulator has a certain inclination. If the inclination angle changes due to unexpected reasons, it will also affect the granulation rate of organic fertilizer particles and the service life.
During the operation of thedisc granulator, the operator shall also pay attention to the temperature change of the machine body at any time. The operator can touch the blade with clean hands. If the blade does not touch the hand, the temperature should rise immediately until the blade touches the hand. Then, during the normal operation of the granulator, the operator should maintain a stable machine temperature and not allow the temperature to rise or fall. In addition, the operator should pay attention to maintaining the temperature around the vent until the head temperature reaches about 200℃.
When using the disc granulator, in order to ensure that the produced particles are uniform, smooth and complete, attention should be paid to ensuring that the feeding is uniform and sufficient. The feeding speed of the equipment should be properly matched with the feeding speed to avoid the decline of particle quality and output.
When the disc granulator body is unstable, pay attention to check whether the coupling clearance is too tight and loosen it in time. If the bearing part of the reducer is hot or noisy, it shall be repaired and oiled in time.
During the installation of the disc granulator, the main body shall be kept perpendicular to the horizontal plane, and the perpendicularity shall be calibrated and corrected after installation.
Before the installation of the disc granulator, the concrete foundation shall be prepared, installed on the horizontal concrete foundation and fastened with bolts.
Before power on, ensure that the power supply meets the power supply requirements set by the disc granulator, and configure the power cord and control switch according to the equipment power supply.
After installation, check whether the bolts of each part are loose and whether the main engine compartment door is fastened.

In the process of using the organic fertilizer disc granulator, if the 10 precautions in the operation process are strictly followed, the granulation rate will be effectively improved, the energy consumption will be reduced, and the service life of the equipment will be extended.

Application effect of composter before processing fertilizer in organic fertilizer production line

fertilizer granulator Jan 4, 2023

Compost turning machine is a necessary equipment in the production process of organic fertilizer. Its main function is to automatically turning the raw materials in the fermentation, so that the materials can better contact with the air, so as to improve the speed of material fermentation. On the other hand, it also plays a role in controlling the composting temperature.

The main purpose of turning over fermented compost is to evaporate excess water, so that the fertilizer and air are fully mixed, and the air is wrapped in the gaps of the compost. The decomposed fertilizer is suitable for the deep processing of fertilizer granulator. The smooth realization of composting fermentation depends on the distance the fertilizer travels in the air after being thrown. To analyze the effect of fertilizer throwing, the following assumptions are made for the thrown fertilizer particles:

1) When the fertilizer particles are thrown away from the Throwing Knife, the initial velocity of their motion is equal to the absolute velocity of the throwing knife speed and the involved velocity of the tipper

2) The movement of fertilizer particles has no influence on the movement of adjacent fertilizer particles

3) The trajectory of fertilizer particles is a continuous curve.

There are many types of organic fertilizer turning and throwing equipment on the market, and the actual use functions are also very different. The main selection factors are determined according to the customer’s terrain conditions, fertilizer production line technology, investment scale and other aspects. One of the most commonly used and lowest cost compost turning equipment is the trough turning machine. The smallest size is two meters in width. Of course, the large trough turning machine can reach more than 10 meters, and the price is more than 20,000 US dollars.

In addition to the above-mentioned trough turning and polishing machines, there are many types of organic fertilizer fermentation equipment, which are divided into two categories, trough turning and turning machines and walking turning and turning machines. The walking type turning machine is divided into crawler type and wheel type.

Composting Solution of Organic Fertilizer Crusher

fertilizer granulator Dec 29, 2022

In recent two years, with the rapid development of social economy, we believe that people are more and more familiar with the organic fertilizer grinder, but we often encounter the problem of organic fertilizer composting. So how do we control these steps in this process? Now let’s see.

Water conditioning, water is necessary for microbial growth. During composting, 50-60% water (by weight) is conducive to microbial synthesis. The water content of livestock manure is 75-80%, and straw with low water content is usually used for conditioning.

The control of fermentation temperature is one of the important conditions for the normal fermentation of organic materials. In cold climate areas, heating and heat preservation measures should be taken to ensure the normal stop of fermentation process. At present, the economic and feasible method is to use solar energy to heat and heat materials. The greenhouse principle can be applied to the design of fermentation equipment. The fermentation equipment shall be made of PVC or glass fiber reinforced plastic roof materials and wall materials with good light transmission performance and durability. The fermentation equipment should be well sealed and well insulated in winter; At the same time, it shall be convenient for ventilation and provide oxygen for material fermentation.

Regulate carbon nitrogen ratio

Generally speaking, the C/N ratio of livestock manure is lower than 20:1, while that of straw is higher than 50:1. If the C/N ratio of the fermentation material is adjusted to 25-35:1, on the one hand, a part of straw can be added to livestock manure to adjust the C/N ratio, and on the other hand, the moisture content of straw is low.

Pile up

Aeration is an important factor affecting composting temperature and fermentation effect. The purpose of turning the pile is to improve the ventilation condition in the pile, distribute water, promote the propagation of high-temperature beneficial microorganisms, make the pile temperature reach 60~70 ℃, accelerate the transformation of fermentation materials, so as to achieve the purpose of average mixing, heating and decomposition. The materials can be turned over manually, or by wheeled dumpers, loaders, deep groove aerobic dumpers and other machines. In the process of fermentation, it is suitable to turn it for 1-2 times a day.

screening

In order to improve the commercial value of organic fertilizer products and facilitate packaging and storage, the screening process is usually used to separate large materials. There are many kinds of screening equipment, such as cylinder screen, vibrating screen, etc. In order to reduce investment, manual screening can also be used. The materials above the screen can be landfilled or reused as fermentation auxiliary materials, and the materials below the screen can be used as organic fertilizer products.

Aerobic dynamic composting core equipment Organic fertilizer composter

fertilizer granulator Dec 29, 2022

Organic fertilizer composter is the core equipment of aerobic dynamic composting. As a new type of machinery, it is unknown in the national product catalog, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace manual and forklift dumping, and is the mainstream product that affects the development trend of the composting industry. The importance of organic fertilizer composter stems from its role in composting production:

Mixing effect in raw material conditioning

In order to adjust the carbon nitrogen ratio, pH and water content of raw materials, some auxiliary materials must be added to the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, which can be evenly mixed by the dumper to achieve the purpose of tempering.

Adjust the temperature of the raw material pile

During the operation of the stacker, the raw material particles fully contact and mix with the air, so that a large amount of fresh air can be stored in the material stack, which is conducive to the active production of fermentation heat by aerobic microorganisms and the improvement of the stack temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. The state of medium temperature high temperature medium temperature high temperature alternation is formed, and various beneficial microorganisms are rapidly growing and reproducing in the temperature range suitable for beneficial microorganisms.

Improve the permeability of raw material pile

The turnover system can process the materials into small pieces, making the thick and dense raw material pile fluffy and elastic, forming appropriate pores.

Adjust the water content of the raw material pile

The suitable water content of raw material fermentation is above 55%, and the water content of finished organic fertilizer is below 20%. In the process of fermentation, new water will be produced by biochemical reaction, and the consumption of raw materials by microorganisms will cause the water to lose its carrier and become free. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation caused by heat conduction, the turning of raw materials by the organic fertilizer composter will also cause forced water vapor emission.

Special requirements for composting process

For example, crushing raw materials, giving a certain shape to the raw material pile or realizing quantitative replacement of raw materials.
