When choosing a suitable organic fertilizer granulator, it should be determined based on the characteristics of different feces. Here are some common types of feces and corresponding recommendations for selecting organic fertilizer granulators:

Cow manure:

Cow manure has a moderate moisture content and high organic matter content, making it suitable for granulation treatment using a wet granulation machine.

The fiber content of cow manure is relatively high, and a wet organic fertilizer granulator with crushing function can be selected to improve the shaping effect of particles.

Chicken manure:

Chicken manure has a high moisture content and abundant organic matter, making it suitable for use with wet or semi dry granulators.

Due to the high viscosity of chicken manure, it may be necessary to add an appropriate amount of desiccant or conditioner to adjust its moisture and adhesion.

Pig manure:

Pig manure has a high moisture content and abundant organic matter, making it suitable for granulation treatment using a wet granulation machine.

Pig manure has strong adhesion and may require the addition of an appropriate amount of desiccant or conditioner to reduce its viscosity and facilitate granulation.

Sheep manure:

Sheep manure has a moderate moisture content and high organic matter content, making it suitable for granulation treatment using a wet granulation machine.

The fiber content of sheep manure is relatively low, and a wet granulation machine without crushing function can be chosen to reduce the damage to the fibers.

Rabbit feces:

Rabbit manure has a low moisture content and rich organic matter content, making it suitable for granulation treatment using a dry granulation machine.

The particle size of rabbit manure is relatively small, and a dry granulation machine with strong particle size adjustment function can be selected to achieve the desired particle size.

Other animal manure:

For other types of animal manure, such as pigeon manure, goose manure, etc., a suitable granulator should be selected based on their specific physical and chemical characteristics.

Generally speaking, these feces can also be processed using wet or dry granulation machines, but may require appropriate adjustments based on their characteristics.

When choosing an organic fertilizer granulator, in addition to considering the characteristics of the manure, factors such as production scale, investment budget, and energy consumption should also be taken into account. At the same time, in order to ensure the granulation effect and product quality, it is recommended to conduct sufficient testing and evaluation before purchasing.

The double shaft mixer specially designed and produced by our factory is a new type of equipment based on the original mixer. The mixer is mainly used in organic fertilizers, NPK fertilizer manufacturing process and dust collectors in thermal power plants. It can also be used in chemical metallurgy, mining, building materials and other industries.

The newly produced double shaft mixer has the characteristics of high mixing efficiency and less floor space. The spiral blade (mixing blade) is made of high wear-resistant special alloy or composite ceramic, which has long service life.

Structural advantages of double shaft mixing machine

1. The shell of double shaft mixer is mainly composed of plate and section steel. It is welded in the factory and assembled with other parts, which is the support of double shaft mixer. The shell is tightly sealed, and there will be no fly ash floating and leakage.

2. The water-adding and humidifying piping is mainly composed of pipes, joints and nozzles. The nozzle adopts a stainless steel atomizing cone nozzle, which is arranged above the inside of the casing of the double-shaft mixer, and is arranged axially along the spiral axis to form a water curtain to facilitate the humidification and mixing of the material. The nozzle structure is simple, easy to replace, stainless steel material, anti-corrosion and durable. The moisture content of wet ash can be adjusted by operating the manual regulating valve on the water supply pipeline of the twin-shaft mixer.

3. There are six inspection holes on both sides of the double-shaft mixer to facilitate the operator’s usual inspection and maintenance. The materials fully mixed by the mixer can directly enter the rotary drum granulator for granulation.

4.Spiral shaft is the main component of double shaft mixer, which mainly includes left and right spiral shaft, bearing seat, bearing sleeve, bearing cover, gear, sprocket, oil cup, blade and other parts. The left-right spiral shaft requires high manufacturing accuracy and good process performance, and has strict matching requirements with bearing seat, bearing sleeve and bearing cover. Gear, sprocket are protected by protective cover, can be safe and effective operation.

The oil cup of double shaft mixer is press fit type, which is convenient and effective to fill lubricating oil. The material of the blades of the double shaft mixer is the composite ceramic which is wear-resistant and not easy to stick ash. The blade structure design is reasonable and simple, easy to replace after wear, and has long service life in the organic fertilizer manufacturing process.

Can manure straw be used as organic fertilizer if it is not decomposed? The answer must be “no”. Only when the manure is completely decomposed by compost turning machine, and then made into organic fertilizer, the seedlings will not burn and rot. Most of the diseases and insect pests were killed by high temperature fertilizer.

Fermentation turner is the best choice for organic fertilizer manufacturers. After harmless treatment by organic fertilizer manufacturing process, organic fertilizer eliminates harmful bacteria and insect eggs, decomposes and transforms organic protein in a short period of time, has no odor, and commercial fertilizer is easy to transport. However, the general self-made fertilizer has the characteristics of long stacking time, low harmless degree, large amount of harmful bacteria, viruses, insect eggs and weed seeds, easy to burn roots and seedlings, and can not be sold as commercial fertilizer. Therefore, organic fertilizer manufacturers will purchase fermentation and compost turner machines to process farm manure.

Fermentation turner is an important link in the production process of organic fertilizer. Farmyard manure fermented by trough dumper is a kind of organic fertilizer with rich nutrient content. It has both a large amount of organic matter and high content of three elements. nutrient. The organic matter content is 25.5 percent, nitrogen is 1.63 percent, phosphorus is 1.54 percent, and potassium is 0.85 percent. Our hot-selling trough compost turning machine adopts track-type walking, so that the turning and throwing production process has good reliability, and the energy consumption is reduced. The matching trough changer can double the output, increase economic income and reduce equipment investment.

Our factory provides NPK fertilizer manufacturing process, organic fertilizer production equipment, we produce a wide range of fermentation compost turning machine models, according to the user’s fermentation tank width size custom turner machine.

The effectiveness of pig manure fertilizer is influenced by the granulation process of organic fertilizer granulators, mainly reflected in the following aspects:

Fertilizer release rate:

The pig manure fertilizer produced by wet organic fertilizer granulators usually has a slower release rate of fertilizer efficiency because the addition of water helps to maintain the stability of nutrients in the fertilizer. This is beneficial for long-term crop growth and soil improvement.

The pig manure fertilizer produced by dry granulation has a fast release rate of fertilizer efficiency, which is suitable for the short-term rapid growth needs of crops, but may require more frequent application.

Nutrient utilization efficiency:

Wet granulation, due to its slow fertilizer release characteristics, helps to improve nutrient utilization and reduce nutrient loss, especially for nutrients such as nitrogen and phosphorus.

Dry granulation may lead to rapid loss of some nutrients due to the rapid release of fertilizer efficiency, especially under rainwater erosion, and may need to be used in conjunction with soil water and fertilizer conservation measures.

Soil environmental impact:

Wet granulation may generate a certain amount of wastewater and exhaust gas, which, if not treated properly, may cause pollution to the soil and surrounding environment.

The impact of dry granulation on soil environment is relatively small, but dust may be generated during the production process, and appropriate dust prevention measures need to be taken.

Convenience of application:

The pig manure fertilizer produced by wet granulation has a larger volume and heavier weight, making it less convenient to transport and apply than dry granulation, especially in large-scale agricultural operations.

The pig manure fertilizer produced by dry granulation has a small volume, light weight, and is easy to transport and apply, especially in manual application or small-scale mechanical operations.

economic performance:

The production cost of wet granulation is relatively high, including energy and raw material consumption, but due to its high fertilizer efficiency utilization and long fertilizer duration, it may have good economic benefits in the long run.

The production cost of dry granulation is relatively low, but due to its rapid fertilizer release and possible nutrient loss, it may require more application times, thereby increasing long-term costs.

When choosing the organic fertilizer granulator process for pig manure fertilizer, factors such as crop growth needs, soil conditions, environmental protection requirements, and economic benefits should be comprehensively considered to select the most suitable process for local agricultural production conditions.

 The solid-liquid separator is widely used in the industrial field. It is widely used in the fecal treatment in the early stage of the organic fertilizer production line, which is recognized by everyone. This is inseparable from the advantages of the equipment itself. Next, we will introduce the performance advantages of the solid-liquid separator for fecal sewage.

1. Full automaticity

The equipment is equipped with a non clogging submerged pump to pump the cow manure and pig manure water into the solid-liquid separator, and then the water is gradually pushed to the front of the machine by the auger. At the same time, the pressure of the front edge of the machine is continuously increased, forcing the water in the material to extrude out of the screen and flow out of the drainage pipe.
2. Continuity

The work of the solid-liquid separator is continuous. The cow dung / pig dung water is continuously lifted into the solid-liquid separation body, and the pressure of the leading edge is constantly increased. When it reaches a certain extent, the discharge port is pushed open and extruded to achieve the purpose of extrusion discharge.
3. Convenience

In order to master the discharging speed and water content, the counterweight under the main engine can be adjusted to achieve a satisfactory and appropriate discharging state. If too much cow dung water / pig dung water is pumped in, it will be discharged to the original cow dung / pig dung pool through the overflow pipe. The cow dung wastewater separated by spiral extrusion filtration can be directly sent to the biogas digester for biogas fermentation or to the wastewater sedimentation tank.
4. Environmental protection

Dry cow manure/pig manure is squeezed out from the discharge port. After solid-liquid separation, the COD and BOD in the manure water are greatly reduced, which is convenient for subsequent discharge up to standards. The separated manure and sewage can be directly discharged to the biogas digester for biogas fermentation. The fermented manure liquid is a very good organic fertilizer liquid, and can also be discharged to the biogas digester for environmental protection treatment. The remaining manure residue can be fermented into organic fertilizer by compost turning machine.

Huaqiang fertilizer machine manufacturer supplies professional compound fertilizer equipment and designs NPK fertilizer manufacturing process. The scale of fertilizer production line can be from 2000 tons to 100000 tons per year.

The formula of organic-inorganic compound fertilizer is the same as that of inorganic fertilizer according to different soil and different crop formula. If the fermentation is sufficient and the formula is proper, the effect is better than that of inorganic fertilizer, and the cost is lower. It can also improve the living environment of plants and is green fertilizer.

Organic-inorganic compound fertilizer refers to a solid fertilizer that uses harmless treatment of organic matter (including high-temperature compost) and inorganic fertilizer (mainly nitrogen, phosphorus, and potassium fertilizer) as the main raw materials, and is mechanically processed through the organic fertilizer manufacturing process. This compound fertilizer is configured according to the nutrient characteristics of the soil and crops and the purpose of fertilizing the soil, and has the characteristics of nutrient balance.

The horizontal mixer is used in the mixing stage of NPK fertilizer manufacturing process to fully mix different kinds of nutrients to prepare for the granulation of rotary drum granulator.

Performance characteristics of horizontal mixer

The rotation speed of the shaft driven by the reducer and the structure of the blade will weaken the gravity of the material. With the lack of gravity, the difference of particle size and specific gravity of the material is ignored in the mixing process.

The intense stirring movement of horizontal mixer shortens the mixing time, which is faster and more efficient. Even if the material has the difference of specific gravity and particle size, it can achieve good mixing effect under the rapid and violent tossing of staggered mixing blades. In the manufacturing of NPK fertilizer, the raw materials need to be fully mixed. The mixer has high mixing uniformity and less residue. The horizontal mixer is suitable for mixing more than two kinds of fertilizers, additives and premix.

The impact of the granulation process of the pig manure organic fertilizer granulator on product quality is mainly reflected in the following aspects:

Particle size distribution:

Different granulation processes can affect the particle size distribution of the final product. Wet granulation usually results in a relatively uniform particle size distribution, while dry granulation may produce significant particle size differences.

Particle strength:

Wet granulation, by adding water or other liquids as binders, can increase the strength and hardness of the particles, making them more suitable for storage and transportation.

The particle strength of dry granulation is relatively low, but the energy consumption during the production process is low.

Moisture content:

Wet granulation can increase the moisture content of the product, which may affect storage and subsequent processing.

Dry granulation has a lower moisture content, but may require additional drying processes.

Organic matter content:

The granulation process may affect the conversion efficiency of organic matter in pig manure, thereby affecting the fertilizer efficiency of the product.

Wet granulation facilitates microbial activity and may promote the conversion of organic matter.

Environmental impact:

Wet granulation may generate wastewater and exhaust gas, and appropriate treatment measures are needed to reduce environmental pollution.

Dry granulation has a relatively small impact on the environment.

Production efficiency:

The production efficiency of wet granulation is usually higher than that of dry granulation because its drying and granulation processes can be carried out continuously.

The production efficiency of dry granulation is relatively low, but the energy consumption is also low.

Cost:

The production cost of wet granulation is relatively high because it requires additional energy and materials to regulate humidity.

The production cost of dry granulation is lower, but the product quality may not be as good as wet granulation.

Based on the characteristics of pig manure and the intended use of the final product, a suitable organic fertilizer granulation process can be selected to optimize product quality. For example, if high-strength particles are needed, wet granulation can be chosen; If low-cost production is required, dry granulation can be chosen. At the same time, appropriate measures should be taken to reduce the environmental impact during the production of fertilizers by organic fertilizer granulators, taking into account the requirements of environmental protection and sustainable development.

The granulation process of pig manure organic fertilizer granulator is mainly divided into two types: wet granulation and dry granulation.

Wet granulation:

Wet granulation refers to adding a certain amount of water or other liquid during the granulation process to achieve a certain humidity condition for pig manure raw materials, and then extruding them into granules through mechanical force.

The advantage of wet granulation is that it can produce uniform and smooth particles, and the particles have high strength and are not easily broken.

The disadvantage is that it requires more energy to heat and dry wet particles, and the production process may generate wastewater and exhaust gas.

Dry granulation:

Dry granulation refers to the process of directly utilizing the moisture and binder of pig manure raw materials through mechanical force without adding additional water.

The advantages of dry granulation are low energy consumption, simple production process, and no generation of wastewater and exhaust gas.

The disadvantage is that the quality of the particles may not be as uniform as wet granulation, and the strength of the particles is relatively low, making them easy to break.

The working temperature of the pig manure organic fertilizer granulator usually depends on various factors, including the properties of the raw materials, the required final product characteristics, and the production process. In practical operation, the working temperature of the pig manure organic fertilizer granulator is generally between 50 ℃ and 100 ℃. Within this temperature range, organic matter in pig manure is more easily decomposed by microorganisms, which is beneficial for the activity of the binder and thus facilitates the smooth granulation process.

However, the specific working temperature still needs to be adjusted according to the actual production situation. For example, if the moisture content in the raw material is high, it may be necessary to increase the working temperature to accelerate the evaporation of moisture; On the contrary, if the moisture content in the raw material is low, it may be necessary to lower the working temperature to prevent particle hardening caused by rapid evaporation of moisture. In addition, excessively high operating temperatures may lead to excessive wear and tear of the equipment, while excessively low operating temperatures may affect the granulation effect.

Therefore, in practical operation, the working temperature of the organic fertilizer granulator should be reasonably set according to the specific properties of pig manure and production process requirements to ensure the stability of the production process and the reliability of product quality. At the same time, close attention should be paid to the operating status of the equipment, and process parameters should be adjusted in a timely manner to adapt to changes in raw materials and environmental conditions.

NPK compound fertilizer production line needs a lot of supporting equipment to complete the whole granulation production task when processing fertilizer. In these many supporting equipment, there is a mixing equipment, fertilizer mixer for mixing materials.

Horizontal mixer for intermittent operation, it is suitable for rotary drum granulator mixing operation. General fertilizer production should be equipped with two or more sets to keep the production flexible to meet the market demand.

Fertilizer mixer is the supporting production equipment of the whole compound fertilizer production equipment. We can calculate the specific model and specification according to the output of the fertilizer production line. If the specification of the mixing equipment is too large, it may cause a waste of energy. If it is too small, it will affect the normal production, so we must choose the appropriate one.

1. Operate in strict accordance with the operation manual of NPK fertilizer manufacturing process, and use professional fertilizer equipment staff to ensure that the professional level of staff meets the standard.

2. The maintenance of fertilizer equipment should be done well at ordinary times. If possible, the fertilizer production equipment can be prevented from being exposed to the sun. Especially NPK fertilizer granulator, batching system, packaging machine and other key equipment.

3.The intelligence of fertilizer equipment can also avoid the damage of many human factors. So please look for our fertilizer machines when purchasing fertilizer equipment. Our fertilizer equipment has reasonable structure, low failure rate and simple operation of fertilizer production process.
