Windrow composting is a method of composting organic materials in long, narrow piles called windrows. The windrows are typically between 4 and 8 feet high, 8 to 12 feet wide, and as long as necessary to accommodate the amount of organic waste being composted. The windrow composting method is commonly used in commercial-scale composting operations, whether it is small scale fertilizer composting or large scale fermentation. And can be done both outdoors or in a covered facility.
The process of windrow composting involves building a pile of organic materials such as farm waste, industrial waste, manure, and agricultural residues. The pile is then regularly turned, usually with a professional windrow machine, to add oxygen and create the right conditions for microorganisms to break down the organic matter. The temperature of the compost pile is monitored regularly, and if necessary, additional water or bulking agents such as wood chips may be added to maintain optimal conditions for composting.

The duration of the windrow composting process varies depending on the type of organic material being composted, the size of the pile, and the environmental conditions. In general, the composting process takes between 3 and 6 months to complete. When the compost is fully mature, it is a dark, crumbly, and nutrient-rich soil amendment that can be used in agriculture, horticulture, landscaping, and erosion control.
Windrow composting is an effective way to manage organic waste and produce high-quality compost. However, it requires significant space and equipment, making it more suitable for commercial-scale composting operations than for individual households.

When composting, many people often do not get the desired results. This article will focus on five considerations and operating tips. If you are looking for ways to speed up the composting process, this article will be suitable for you.
Shred compost material
Crushing and grinding compost materials as much as possible, the finer the ingredients, the faster the composting rate. After the compost material is crushed, the surface area is greatly increased, which makes it easier for microorganisms to decompose, thereby accelerating the material decomposition process. Here, SX can offer you suitable crusher for compost fertilizer.
Proper mixing ratio of brown and green materials
Composting of organic fertilizer is a game of carbon to nitrogen ratio. For example, dry leaf sawdust, wood chips and other components are usually rich in carbon (C), from the color point of view, it is often similar to brown, so it is also called brown material. However, the kitchen waste, grass clippings, fresh cow dung, etc. are rich in nitrogen (N), and are often green in color, so they are called green materials.
Maintaining an appropriate mixing ratio of brown materials and green materials, as well as thorough mixing, is a prerequisite for the full decomposition of organic waste. As for the volume ratio and weight ratio of materials, scientifically speaking, it needs to be based on the carbon-nitrogen ratio of different materials. to calculate. For small composting, my suggestion is to refer to the Berkeley composting method, the basic composition of brown material: green material (non-feces): animal manure volume ratio is 1:1:1, if there is no animal manure, you can use green material Instead, brown material: green material is about 1:2. Based on this, just observe the follow-up situation and adjust. For large composts, adjustment costs are high and more precise calculations are required.
Moisture is essential for the smooth decomposition of compost. Too much or too little moisture both will hinder the whole process. Generally, if the water content of the compost exceeds 60%, it will cause anaerobic fermentation and stink, while the water content of less than 35% cannot be decomposed, because the microorganisms will not be able to continue their metabolic process. It is difficult to measure the water content accurately, but the basic experience of testing the water content is to take out a handful of material mixture, squeeze it hard, and finally drop a drop or two of water, that’s right.
Turn the compost
Do you know how to stir-fry? If you don’t stir-fry, it’s easy to burn. The same logic applies here. Most of them won’t fully compost if you don’t turn them often. The best principle is to turn the pile every three days (Berkeley’s 18-day compost period is to turn it every other day), like peeling onions, turn the ones that were originally on the outer layer to the center of the pile, and turn the ones that were originally in the center of the pile. come outside. Turning helps improve air circulation and distributes microbes evenly throughout the pile, which speeds up decomposition. Go here for the best compost turning machine.
Add microbes to your compost
Microorganisms are the protagonists of decomposing compost. They are working day and night to decompose compost materials. Therefore, when starting a new compost heap, if some good microorganisms are introduced correctly, the compost heap will be filled with a large amount of compost after a few days. These microorganisms allow the decomposition process to start quickly. So we usually add something called “compost starter”, don’t worry, it’s not a commercial commodity, it’s just a handful of old compost that has decomposed, or compost that decomposes quickly, dead fish or even Urine will do.

The most commonly used treatment of livestock and poultry manure is high-temperature aerobic composting technology, which is a process of using microorganisms to decompose biodegradable organic solid waste into relatively stable humus substances under certain temperature, humidity and pH conditions. High-temperature aerobic composting is an effective way to realize the harmlessness and utilization of organic waste. Its technological process is mainly composed of pretreatment, aerobic fermentation, post-treatment and storage. Its key technologies are mainly pretreatment and aerobic fermentation.
Compost pretreatment is mainly to adjust the moisture, pH and carbon-nitrogen ratio of compost raw materials, and to add microbial fermentation agents to compost raw materials. The initial moisture content of composting feces should generally be 40% to 60%. Too low moisture is not conducive to the growth of microorganisms, and too high moisture will block the gaps in the compost, affect ventilation, lead to anaerobic fermentation, slow down the degradation rate, and prolong Heap time. pH is a parameter to evaluate the living environment of microorganisms, and the most suitable pH in the composting process should be 5.5-8.0. In the composting process, the pH value is generally considered to be a non-important factor, because most bacteria can grow and multiply in the pH range of 5.5-8.0. The carbon and nitrogen balance of compost raw materials is a key factor for the optimal biological activity of microorganisms. The carbon-nitrogen ratio of compost raw materials is generally more suitable between 25:1 and 35:1. The carbon-nitrogen ratio is small, the temperature rises quickly, but the maximum temperature reached by the stack is low; the carbon-nitrogen ratio is large, the maximum temperature reached by the stack is high, but the temperature rises slowly. In actual production, materials such as straw, rice husk or sawdust can be used to adjust the carbon-nitrogen ratio. Composting is a biochemical degradation process in which microorganisms act on organic matter. Microorganisms are the main body of the composting process and the most critical and active components in the composting process. Adding microbial fermentation agents to compost raw materials can accelerate the decomposition and maturity of organic matter in compost raw materials and promote the release of available nitrogen in organic materials.

2. Aerobic fermentation
The aerobic fermentation composting process consists of two stages: primary fermentation and secondary fermentation. The time required for composting operation varies with the carbon-to-nitrogen ratio, humidity, weather conditions, and the type of composting operation and management. Under normal circumstances, the fermentation period is about 9 to 35 days. Primary fermentation refers to the stage from the temperature rising to the beginning of falling, which is the first stage of compost fermentation. Oxygen supply to the compost bed or fermentation unit is usually required at this stage. Oxygen is a necessary condition for the survival of aerobic microorganisms. Sufficient oxygen supply is an important condition to ensure the reproduction and development of aerobic microbial populations, and has an important impact on the composting time and the quality of the final product. SX can provide you with professional equipment for organic waste composting. It is generally believed that the volume content of air oxygen in the compost should be kept at 5% to 15%, and if it is lower than 5%, it will lead to anaerobic fermentation; if it is higher than 15%, the compost body will be cooled, resulting in the survival of a large number of pathogens. At present, the ventilation methods used by organic fertilizer equipment mainly include using power shovel or other special equipment to turn the pile, inserting a ventilating pipe with holes into the dung pile, using high-pressure fans to force ventilation and natural ventilation to supply oxygen, etc. During the primary fermentation process, the temperature of each test point in the stack should be kept at 55-65°C, not higher than 75°C, and the duration should not be less than 5 days. Secondary fermentation refers to the fermentation process in which microorganisms decompose refractory organic matter and fermentation intermediate products at a relatively low speed after the compost undergoes primary fermentation. Ventilation is usually not required at this stage, but regular compost turning should be performed.

The windrow compost turning machine can be said to be the core equipment in the current organic fertilizer production process. It can control the fermentation temperature and the moisture in the stack during the windrow fermentation process. At present, the more advanced compost machines on the market can achieve no dead angle turning, and can complete the composting operation of all materials in one workflow.
1. Pay attention to the temperature, oxygen content and moisture content in the fermentation raw materials. Temperature, oxygen and moisture are directly related to the windrow fermentation cycle of organic fertilizers and the quality of the finished product. Therefore, special attention should be paid to these three aspects when using a turning machine to ferment organic fertilizers. The purpose of the turning operation is to control the temperature, increase the oxygen content in the material, and reduce the moisture content, but it is also necessary to pay attention not to turn too frequently, so as not to affect the temperature increase in the stack. Click here for more details
2. The stacking should not be too high. When using a turner for fermentation, the width of the windrows can be determined according to the output. The height of the compost should be between 0.8 and 1.5 meters. If the height of the compost is too high, it will affect the air permeability of the raw materials, resulting in oxygen content in the stack. Insufficient amount affects fermentation.
3. Pay attention to the freshness of the raw materials. If the raw materials are stored for too long, anaerobic conditions may be formed. Under the anaerobic state, the organic matter content in the raw materials will gradually decrease, which will affect the quality of the finished products. If such raw materials are used to ferment organic fertilizer, attention should be paid to adding fresh raw materials for adjustment.
4. Pay attention to the turning time of windrow composting. When using a turning and throwing machine for fermentation, it usually takes 10-15 days for the initial fermentation to decompose. The turning and throwing time can be determined according to the temperature in the stack. It is tossed a second time, followed by a second aging and fermentation, usually 3-7 days.
5. Pay attention to the nature of the fermentation raw materials. There are many raw materials that can be used to ferment organic fertilizers, such as grass and wood fragments, crop straw, livestock and poultry manure, etc., but the carbon and nitrogen ratios in different raw materials are different, and the fermentation cycle is also different. To ensure the quality of the finished product after fermentation, targeted adjustments should be made before fermentation, which can be applied after mixing different raw materials evenly.
Compost turner has become the core equipment of dynamic aerobic composting in virtue of the important effects on compost and fermentation.
Mixing function in tempering of raw materials: in composting, it is necessary to add some minor ingredients in order to adjust the carbon nitrogen ratio, pH value and water content of raw materials. Main raw materials and minor ingredients that are put together according to certain proportion could be mixed uniformly by professional compost turner for better tempering.
Adjusting the temperature of raw material piles: during the working process, compost turning machine can make raw materials fully contracts and mixture with air, which can adjust the temperature of piles conveniently. Air helps aerobic microorganisms to produce fermentation heat actively, pile temperature rising. Meanwhile, if piles temperature is high, turning piles can bring the supply of fresh air, which can lower the temperature. And various beneficial microorganisms grow and breed in the adaptive temperature range.
Improving the permeability of ingredient piles: composting system can also crush the stick and ropy raw materials into small mass, making piles fluffy, stretchy, and with appropriate porosity, which has been an important standard to measure the performance of compost turner.
Adjusting the moisture of raw material piles: The water content of raw materials for fermentation should be controlled within 55%. In the fermentation process, biochemical reaction would generate new water while the consumption of microorganism to raw materials also cause water dissociate due to losing carrier. And using composting machine to turn piles could emit vapour compulsorily
Realizing the special requirement of composting process: For instance, compost turn could realize the requirements of crushing raw materials or mensurable shifting. Go here to know more about compost turner
Tips for Choosing Compost Turner
Whether you’re just entering the market, or are experienced with composting and looking to grow your operation, questions always arise as to what type of compost turner would best fit your needs and bottom line.The choices would narrow substantially after considering the factors, conditions and objectives of the composting operation.
When purchasing a compost turner, evaluate the equipment with regard to the safety of the operator, other site workers and bystanders. As a minimum, make sure the equipment has the CE mark.
The output of a compost turner is determined by its working travel speed and the size of the windrow that it can handle. Larger and more powerful machines generally have greater throughput rates because they process larger raw material piles, so readers could choose it according to the required material piles turning throughput.
Cost and budget, of course, also affect the choice of composting equipment. The machine with larger throughout and capacity would have higher prices, so choose one suitable for your requirement and budget.
When purchasing organic fertilizer equipment, we need on-site inspection. Only after on-site inspection can you choose the correct organic fertilizer equipment through your own observation. You can judge the quality of organic fertilizer equipment from the surface observation of the equipment, from the sound law in operation, and from the trial-processed product organic fertilizer. Another point is the rationality of the process. The following contents are for your reference.
Look at the finished products processed by the organic equipment: the two products of organic fertilizer processing, powdered organic fertilizer and granular organic fertilizer, both have particle size standards, and the size of the particle size is within the different range, indicating that the organic fertilizer equipment is relatively reliable.
Look at the surface treatment of the equipment: the appearance of the organic fertilizer equipment, the fineness of the surface treatment, the treatment of welding, the treatment of riveting, etc. From the outside, the appearance of the junction is tight and meshed.

When it comes to small-scale organic fertilizer production lines, many people may think that it is the organic fertilizer processing method that farmers make to pollute the surrounding air and groundwater, but it is not always the case. Qualified commercial small-scale organic fertilizer production lines, covering an annual output of 3,000 tons – 20,000 tons per year, need to invest in professional organic fertilizer equipment – organic fertilizer turners, pulverizers, granulators, etc., which are currently in line with environmental protection conditions, subject to protected by the state. Let’s talk about the production method of small-scale organic fertilizer that is environmentally friendly and supported by state finance.
The process of small organic fertilizer production generally adopts in-vessel fermentation or trench fermentation, and the other is advanced biogas production, and then fermented into organic fertilizer. This is a relatively common early stage of organic fertilizer processing in the market. The initial process method of small organic fertilizer production line is as follows:
1. Pile livestock and poultry manure and other materials, household garbage, sludge and other fertilizer base materials on a flat ground in strips. (The trough turning machine directly puts the auxiliary material into the trough), the stacking width is equal to the turning width of the equipment, the height should be as high as possible, and the length should be as long as possible, such as 50 meters, 100 meters, etc., the ground should be flat, cement , The land can be used (as long as it is flat and has a certain hardness), each 10,000 tons of production requires a site of 5-6 acres, and the trough type turning machine will cover a relatively small area). SX can provide you with suitable equipment for organic fertilizer making
⒉Sprinkle the piled livestock and poultry manure and other materials, domestic garbage, sludge and other fertilizer base materials with biological fermentation bacteria
3. Use a pile turning machine or a trough turning machine to evenly mix straw, livestock and poultry manure and other materials, domestic waste, sludge, (water content should be 50%-70%), fermentation bacteria, etc., 3 – 5 hours to deodorize, 16 hours to heat up to 50 degrees, when the temperature reaches 55 degrees, turn the heap again to add oxygen, and then start stirring when the material temperature reaches 55 degrees, which has the effect of uniform fermentation, oxygenation and cooling , and repeat the last process until it is completely decomposed.

4. If the water content of livestock and poultry manure and other materials, domestic garbage, sludge, etc. is too high, you can add organic matter, relatively dry auxiliary materials that can absorb water, or use the method of reflux to put the last dried fertilizer below to form strips. Put the livestock and poultry manure and other materials, domestic garbage, sludge, etc. with a large water content in the middle, so that the water on the top can seep to the bottom and then turn it over.
5. The general fertilization process takes 7-10 days. Due to different climates, it may take 10-15 days for the material to be completely decomposed, achieving no odor, no germs, eggs, weed seeds, and high humus content. , Potassium content increased and so on. Powdered organic fertilizer is made.
6. Then use equipment such as pulverizer, grading sieve, automatic packaging machine packaging, etc., powdered organic fertilizer can be put into storage and sold.
If you plan to make powdered organic fertilizer, it can be sold in the market after the above-mentioned preliminary process is completed. However, considering the inventory time and the maintenance of fertilizer efficiency as a commodity, it needs to be further processed into the granular organic fertilizer in the above-mentioned process.
When processing granular organic fertilizer, the process of small organic fertilizer production line is described above with the following process flow:
1. Use the organic fertilizer granulator to process material into 3mm-5mm-8mm and other granules;
2. Screening machine for screening;
3. The granules that meet the specifications after sieving enter the lower-level process, and those that do not meet the requirements are returned to the pulverizer for reprocessing and re-granulation. It should be noted that the SX organic fertilizer granulator has a one-time pull rate of more than 95%.
4. Transfer to dryer and cooler for drying. Cooling
5. In order to maintain fertilizer, it is also necessary to coat the granules, that is, the coating process of the coating machine;
6. The coated granules are transported to an automatic weighing and packaging machine for packaging;
The above is the organic fertilizer amnufcturing process that meets the environmental protection requirements and meets the national organic fertilizer standard. After years of improvement in production practice, this small organic fertilizer production line has advanced technology, stable production capacity, reliable quality and excellent equipment performance.

The working principle of the organic fertilizer production line:
The processing of amking organic fertilizers is mainly to collect raw materials, and then proportion the raw materials according to the required formula, adjust the moisture and carbon-nitrogen ratio of the raw materials, and start fermentation.
Fermentation Turner: During the fermentation process, the raw materials are turned over by organic fertilizer compost turner to provide sufficient oxygen for the raw materials, and the temperature is controlled to make the raw materials ferment more uniformly and fully.
Crusher: The size and state of the fermented materials are not uniform, and the semi-wet material crusher can be used for fine pulverization.
Drying and cooling machine: The organic fertilizer made into granules still contains about 30% moisture. In order to increase its strength, the granules need to be dried and cooled. It is also more convenient for later storage and transportation.
Drum screening machine: After granulation, there will be a small amount of unqualified particles, some are too large, some are too small, use a screening machine to screen them out, and those that are too large will be returned to the crusher, and those that are too small will be returned to the granulator for new After granulation, qualified granules will flow into the automatic packaging machine.
Packaging machine: After the finished organic fertilizer granules are packaged by an automatic packaging machine, the entire organic fertilizer processing process is completed.
It should be noted that the above configuration is a conventional organic fertilizer production line configuration. In the actual production process, due to the difference in formula and production process, there will be slight adjustments.
