The Heartbeat of Fertilizer Production

fertilizer granulator Aug 15, 2025

A windrow compost turning machine is a type of composting machinery specifically designed for aerobic fermentation of organic materials. It’s part of the equipment required for biofertilizer production, which typically includes a mixer, fermenter, grinder, and granulator. As a key component of fertilizer equipment, a windrow compost turning machine specializes in organic waste treatment, distinguishing itself from chemical fertilizer machinery in its focus on bio-organic material processing. Its crawler design provides stability and maneuverability for large-scale composting operations within a complete fertilizer production system.

The Central Nervous System

Imagine pretreated materials as ingredients waiting to be cooked, and the windrow compost turning machine as the chef mastering the heat. It precisely turns 2-meter-high organic windrows, much like a chef stir-frying dishes, ensuring every part gets even “heating.” This mechanical ballet can process thousands of tons daily, delivering perfectly fermented materials for subsequent granulation and drying processes.

The Metronome of Mass Production

In large fertilizer plants with annual outputs exceeding 50,000 tons, multiple windrows align like piano keys. The crawler turner moves like a skilled pianist, cycling through different zones following the composition of “fresh material loading – thermophilic fermentation – cooling maturation.” This “multi-zone rotation” enables 24/7 continuous production, transforming organic fertilizer making into true industrial assembly lines.

Did you know? Modern crawler turners’ intelligent control systems allow operators to adjust travel speed and turning frequency as precisely as a car’s accelerator via touchscreens. When downstream granulators speed up, the fermentation rhythm follows in real-time, ensuring the entire production line harmonizes like a symphony orchestra.

The Versatile Performer

Unlike fixed fermentation equipment, crawler turners can either coordinate seamlessly with other devices in modern plants or work solo in open fields. When farms need onsite manure treatment or cities must handle sudden garden waste, this steel giant can “relocate,” bringing production lines to materials rather than the opposite.

From farms to cities, windrow compost turning machines are redefining possibilities in organic fertilizer production. More than just bridges connecting pretreatment and refining processes, they’re alchemists transforming organic waste into black gold. In today’s sustainability-focused world, these flexible, efficient machines have become indispensable hearts of modern fertilizer production lines.

The “Iron Chef” of Compost: Perfect Fermentation by Compost Turning Machine

fertilizer granulator Aug 12, 2025

On the stage of organic fertilizer production, the compost turning machine acts like a masterful “iron chef”, meticulously controlling each fermentation step to “cook” various organic wastes into nutrient-rich compost. Let’s explore this “chef’s” secret recipe.

Step 1: Meticulous Ingredient Preparation

Like a chef preparing ingredients, raw materials first undergo crushing and screening to remove impurities, achieving the “golden size” of 2-5 cm particles. The carbon-nitrogen ratio (25-30:1) and moisture content (50%-60%) are adjusted—the perfect formula for microbial activity. Too wet? Add straw “absorbent”. Too dry? Add water for “seasoning”.

Step 2: Scientific Layering in Trough

Pre-treated materials are evenly spread in fermentation troughs at 0.8-1.5m depth—this “fermentation bed” thickness ensures sufficient heat generation without compromising ventilation. Like baking a cake in the right pan, this thickness is the “gold standard” from years of practice.

Step 3: Precise Temperature-controlled Turning

When material temperature reaches 60-70°C, the “iron chef” begins work. Its turning teeth act like chef’s spoons, flipping and mixing materials so every part can “breathe”. This phase resembles slow cooking, with turning every 1-3 days over 15-30 days, allowing microbes to fully “cook” the organics.

Step 4: Maturity Assessment and Harvest

When temperature drops to ambient level and materials turn dark brown with earthy fragrance, this “organic feast” is ready. The material becomes loose, odor-free, with pathogens eliminated by heat, ready for further “processing”.

Why Choose This “Iron Chef”?

• High Efficiency: 30%-50% faster than manual methods
• Superior Quality: Even turning ensures perfect “doneness”
• Labor-saving: Automated operation reduces workforce
• Eco-friendly: Minimizes odor and energy consumption
• Versatile: Handles diverse “ingredients” from manure to straw

In the kitchen of circular agriculture, compost turning machines are using their “culinary art” to transform waste into “black gold”, providing continuous nutrition for green farming.

How to ferment and turn over raw materials for Organic fertilizer composter

fertilizer granulator Aug 5, 2023

The Organic fertilizer composter is low in cost, simple in operation, and completely controlled by computer. It can change the adjustment of heat preservation and supply of its equipment to the material room according to different seasons to create an environment suitable for the growth of beneficial bacteria. It also uses high-tech technology to make the fermentation cycle of materials in 5 to 6 days, which is completely unaffected by the climate, greatly shortening the fermentation cycle and saving costs.

How to ferment and turn over raw materials for Organic fertilizer composter

1. The role of stirring in raw material conditioning

In fertilizer production, it is necessary to add some auxiliary materials to adjust the carbon nitrogen ratio, acidity, and water content of the raw materials. The main raw materials and various auxiliary materials are roughly stacked together in proportion, and can be mixed evenly through a stacker to achieve the purpose of tempering.

2. Adjusting the temperature of the raw material pile

During the operation of the Organic fertilizer composter, the raw material particles are fully contacted and mixed with the air, and a large amount of fresh air can be stored in the raw material pile, which helps aerobic microorganisms actively generate fermentation heat and improve the stack temperature; When the temperature is high, supplementing fresh air can lower the chimney temperature. A state of alternating medium temperature, high temperature, medium temperature, and high temperature is formed, and various beneficial microorganisms grow and reproduce within the temperature range applicable to the beneficial microorganisms.

3. Improving the permeability of raw material piles

The Organic fertilizer composter can process the material into small pieces, making the thick and dense raw material pile fluffy and elastic, forming appropriate porosity.

4. Adjusting the moisture content of the raw material pile

The suitable water content for raw material fermentation is more than 55%, and the water content standard for finished Manure is less than 20%. During the fermentation process, biochemical reaction will produce new water, and the consumption of microorganisms on raw materials will cause the water to lose its carrier and become free. Therefore, the moisture content decreases in a timely manner during the fertilizer preparation process. In addition to the evaporation caused by heat conduction, the Organic fertilizer composter will turn over the raw materials to form a forced water vapor emission.

5. Special requirements for achieving composting processes

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

The Organic fertilizer composter is an environmental protection and energy saving equipment, with low energy consumption, ensuring zero pollution and deodorization in only one day. This equipment can cultivate various soil friendly biological bacteria and improve soil quality. It can also continuously reproduce in the soil, allowing crops to absorb more nutrients and improve soil fertility and long-term effects.

Characteristics of Organic Fertilizer Fermentation by Chicken Manure Dumping Machine

fertilizer granulator Apr 18, 2023

Chicken manure is a relatively high-quality organic fertilizer raw material, which is inactivated and deodorized during the process of decomposition, which requires the use of fermentation and flipping equipment.

Chicken manure fermentation and tipping machines are widely used in China, such as slot type tipping machines, forklift tipping machines, track type tipping machines, walking type tipping machines, organic fertilizer fermentation tanks, wheel type tipping machines, and chain plate type tipping machines. They are all equipment used in chicken manure fermentation and organic fertilizer in breeding farms. Friends of breeding farms can choose corresponding fermentation and tipping equipment according to their own needs.

The chicken manure organic fertilizer equipment ferments fresh chicken manure with a moisture content of 65% to 85% and an appropriate amount of auxiliary materials (dry straw, crushed grass, dry chicken manure, etc.) in a fermentation tank, while fully stirring with a fermentation equipment (mixer); The tilter continuously tilts the pile to adjust the water content and carbon to nitrogen ratio. The mixed fresh chicken manure is fermented for 7 days under suitable temperature and oxygen conditions, and then sent to the organic fertilizer dryer. The chicken manure block is in full contact with hot air and quickly loses surface moisture. Due to the high-speed rotating crushing equipment inside the dryer, the chicken manure block is constantly crushed and dehydrated, completing the drying process.

On the basis of absorbing traditional compost fermentation processes and combining the strong advantages of equipment research and manufacturing, after years of research and testing, organic fertilizer equipment has been developed. This equipment has the characteristic of full automation. It involves crushing, stirring, granulating, drying, cooling, screening, coating, packaging, and other processing of fermented and decomposed compost, in order to truly harmless treat the materials and produce commercial organic fertilizer particles.

The environmental issue has touched the hearts of countless people, and our chicken manure fermentation organic fertilizer equipment has responded to this issue, playing an environmental role in agricultural production. In the past, when people did not pay enough attention to environmental protection, a large amount of chemical fertilizers were used, which caused serious soil pollution and also led to a large number of chemical pollution sources in the fertilizer industry. This not only poses a threat to the soil, but also poses a threat to people’s physical health. That’s why the country vigorously controls pollution and advocates the use of organic fertilizers.

Farm often uses organic composting machines to ferment agricultural waste

fertilizer granulator Apr 11, 2023

Agriculture is always the top priority, and only by developing agriculture well can we have more confidence to develop other technologies. Therefore, our country’s agricultural policies are also quite good. However, due to years of excessive use of fertilizers, the problem of soil compaction is becoming increasingly serious, which is why there is a strong support for organic fertilizers. Organic fertilizer equipment is specialized in producing organic fertilizers, Organic fertilizers are also very effective in solving the problem of soil compaction and increasing soil organic matter, so it can be seen that the development of organic fertilizers in the future is very good. To achieve circular and safe development in agriculture, it is necessary to use more organic fertilizers to increase the content of soil organic matter.

Organic fertilizer fermentation equipment is a production line composed of multiple equipment links, and the higher the output, the larger the equipment model. The price of different configurations is naturally higher than that of small output. A set of organic fertilizer fermentation equipment is not a fixed set of equipment, but needs to be determined based on the on-site site and materials. For example, chicken manure has a high amount of moisture, and during fermentation, the moisture must be reduced. Corn cobs that are crushed with straw can be added, otherwise they cannot be made into particles; Sheep manure is relatively dry, and when fermenting, it can be directly granulated without the need for adding straw or other materials. The equipment used varies depending on the process.

Special functions of organic fertilizer composting machine:

1. The control cabinet is centrally controlled and can achieve manual or automatic control functions.

2. Equipped with a soft starter, low impact load during startup.

3. Equipped with a gear shifting hydraulic lifting system.

4. The gear teeth are sturdy and durable, with certain crushing and mixing functions for materials.

5. The limit travel switch plays a safety and limit role.

The organic fertilizer composting machine is suitable for aerobic fermentation and can be used in conjunction with solar fermentation chambers, fermentation tanks, and transfer machines. When used in conjunction with transfer machines, it can achieve the function of multiple tanks in one machine. The fermentation tanks it is equipped with can continuously discharge or batch discharge, with high efficiency, stable operation, durability, and even flipping.

Fermentation treatment of chicken manure using a tank type organic fertilizer composter

fertilizer granulator Mar 20, 2023

Fermentation treatment of chicken manure using a tank type organic fertilizer composter

Chicken manure has a high nutritional value compared to other animal manure. However, due to the presence of parasites and infectious bacteria in raw chicken manure, it cannot be directly applied to farmland and must be processed. Common methods include drying and natural drying. The processed chicken manure can be used as feed or fertilizer.

What are the benefits of using a tank type organic fertilizer composter to ferment organic fertilizer

1. Ventilation

The oxygen source of microorganisms is the air layer around them. When oxygen is consumed, CO2 emitted by microbial cells will replace the position of oxygen. Later, the oxygen around the microorganism runs out. If there is no “fresh” air to replace, anaerobic conditions will prevail, creating a foul odor. Therefore, the primary goal of ventilation equipment design is to update the gas environment at a certain rate, so that microorganisms can receive an adequate supply of oxygen.

2. Material turnover

The physical movement of the stack (also known as “agitation”) is achieved through two ways, namely, flipping and stirring. During the flipping process, the material particles are constantly flipped up and down. The stirring process updates the gas around the material particles.

3. Gas replacement During the process of maintaining static state of certain materials, the air layer surrounding the materials is constantly diluted or replaced by the gas generated by the material stack. Therefore, “forced ventilation” has great significance in such composting systems.

4. Cooling to remove excess moisture

In winter, white smoke often overflows from the pile during composting, indicating that it will warm up during fermentation, but only under suitable temperature conditions can beneficial fermentation bacteria multiply rapidly. Therefore, composting can promote the evaporation of excess water, thereby reducing temperature.

5. One machine is used in multiple tanks, with good processing capacity. The tank type composting machine can walk back and forth on the fermentation tank and shift the fermentation tank from side to side, so it has strong processing capacity. The hydraulic trough type stacker can also be lifted and lowered according to the height of the compost material stack, with flexible operation.

What are the common compost fermentation equipment and what is the specific role in the fermentation process

What are the common compost fermentation equipment and what is the specific role in the fermentation process

Composting process, also known as fermentation process, refers to the degradation and stabilization of organic waste under the proper water content, oxygen concentration and other conditions through the action of microorganisms, so as to achieve the purpose of killing parasitic eggs and harmful microorganisms, reducing volatile substances in waste, and at the same time making the organic matter loose for safe treatment and preservation. Because the materials processed by compost fermentation do not contain pathogenic bacteria and weed seeds, they are suitable for application in soil to improve soil conditions.

Composting fermentation process generally includes fermentation, composting, aeration and other links. The equipment used in these links varies with the type of compost. Stack-type composting is to agitate the material by riding the tipper on the stack, thus playing the role of aeration to achieve the purpose of fermentation. Therefore, the device configuration is relatively simple and the function is single. The tank type aerobic fermentation has a distribution system, a tipping system, an aeration system, etc. The equipment is relatively complete, including: distribution truck, organic fertilizer composter, mobile crane, an aeration system, etc. Let’s introduce the functions of these equipment in the fermentation process.

1、 Organic fertilizer composter. In order to meet the requirements of moisture, acidity and alkalinity in material fermentation, some microbial fermenters need to be added. The tipping machine can give full play to its mixing function, so that the mixing operation can achieve the purpose of uniform mixing, stirring and removing the bottom. It can also improve the permeability of raw materials, make the raw materials become fluffy and elastic, absorb a lot of air at the same time, and raise the temperature of the fertilizer pile. If the temperature is too high, it can also absorb fresh air, so that the temperature can be reduced again, In this way, the alternating state of medium and high temperature is formed, which is beneficial to the growth and reproduction of microorganisms.

2、 Cloth truck. The function of the distributor truck is to evenly distribute the materials in the fermentation tank, so that the forklift does not have to enter and leave the fermentation tank frequently, reduce the cost of raw material transfer, and improve the work efficiency.

3、 Move the vehicle. Each tank-type aerobic fermentation system is generally composed of 8-10 fermentation tanks. However, there is only one tipping machine. In order to save equipment investment, multiple fermentation tanks share one organic fertilizer composter. This requires that the tipping machine be switched between different fermentation tanks. The moving crane plays the role of moving the tipping machine and the distribution truck from one tank to another.

4、 Aeration system. The function of the aeration system is to ventilate and aerate the fermentation materials in the tank, so that the microorganisms in the materials can interact with oxygen, and then make the materials fully ferment to produce valuable humus. The fermentation days can be shortened by aeration.

It can be seen from the above introduction that the organic fertilizer tipping machine plays an important role in the whole compost fermentation process. It is necessary to buy a good tipping machine. The dumping effect is good and the efficiency is high. It also has the functions of mixing, crushing and displacement. It also organically combines the electro-hydraulic technology and has a high degree of automation. It realizes the functions of central remote control and one-button operation. According to the needs of users, it can also realize the real-time transmission of temperature, moisture, oxygen content, etc. in the pile.
