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.

Compound fertilizers have always been popular in the fertilizer market due to their large content and fast fertilizer effects. The fertilizer drum granulator is an important equipment for the production of compound fertilizer granules. Then how does rotary drum pellet making machine prepare compound fertilizer? You can find the answer from this post.
The working principle of drum granulator
Drum granulator in the pelleting process of compound fertilizer particles: the core is the small particles with a diameter of Ф1-2mm in the raw materials and returned materials, under the temperature and steam conditions of 60-65°C, with the help of the raw materials’ own viscosity and mechanical The interaction of forces will continue to roll and form soft particles of Ф2-5mm. When drying, with the evaporation of water, the particles will gradually solidify and form hard particles. This is the whole working process of rotary drum granulation.
How to improve pellet quality in rotary drum granulation
When granulating, the material should make an elliptical movement in the granulator or dryer. The material should occupy 1/6 of the cross-sectional area of the cylinder. Through the movement, the materials will rub against each other to produce stickiness, large absorption and small adhesion, and adhesion. into balls. The material should be smooth in motion, and should not be subjected to excessive impact or forced into a ball, otherwise the particle size will be uneven.
The way to improve the roundness of fertilizer pellets is to let the material roll and rub more before the particles are solidified. During the rolling, the surface of the particles is ground to remove the edges and corners, to fill in the gaps, and the more the roll is, the more round it is. Soft particles should not rise and fall vertically in the cylinder of drum pelletizer, otherwise it is easy to cause deformation of the particles and cause the particles to be out of round.

Fertilizer granules produced by rotary drum granulator
In the process of processing compound fertilizers, drum granulators should use low temperature and large air volume to minimize the temperature difference between the drying head and tail. Tail temperature is the focus of control, generally controlled at 45-65°C, urea dosage is 3-9%, tail temperature is controlled at about 65°C; urea dosage is 10-20%, tail temperature is controlled at about 60°C; urea dosage is 21 -38%, the tail temperature is controlled at about 55°C, to prevent the urea from being too high in temperature to melt and produce too much liquid phase, resulting in large particles or sludge. If ammonium chloride is used as the nitrogen source, the tail temperature can be controlled at about 65-80°C, and the drying tail temperature should be formulated and adjusted according to the output size and the actual situation of the equipment. The drying temperature is not fixed. It should be determined mainly by referring to the air volume of the system, the production formula and the drying conditions of the dried materials. The organic coordination of the moisture, temperature and drying temperature of the materials in the granulator is the key.

Twin roll granulator is famous in the fertilizer production industry for dry granulation. It requires the moisture content of the material to be less than 5%. In addition, the roller press granulator is suitable for the production of special compound fertilizers of high, medium and low concern, such as the production of diammonium phosphate, nitrogen, phosphorus and potassium, and urea fertilizers.
In general, a twin roll granulator includes 4 main components.
• The frame part is an integral structure made of high-quality carbon steel plate. All other parts need to be assembled in the rack section. Also, there are holes around the machine. Easy to unload and transport.
• The transmission part refers to the motor drive pulley, V-belt and reducer. This part mainly provides force when the double-roller granulator is working.
• The extrusion granulation part is the key part of the drum granulator. In a complete twin roll granulator there are two rolls which compress the powdered material into large pieces.
• The crushing and separation part is to crush the extruded large flakes into uniform particles. The off-spec fertilizer granules are then separated and need to be returned to the granulation section.
Why choose a twin-roller granulator to produce granular fertilizer?
•Widely applicable to various raw materials. You can not only use twin roll processing machines on npk fertilizer production lines. But it is very applicable in pharmaceutical, chemical, metallurgy, coal, feed and other industries.
• Reduced investment. Extrusion granulators make fertilizer granules at room temperature. So you don’t buy fertilizer dryers and coolers.
• No waste pollution discharge. Our drum granulator uses electricity as the main power. Therefore, the pollution to the environment will be reduced.
• High granulation rate. The ball forming rate of the double-roll granulator is over 90%.

Many people will think of buying equipment to produce organic fertilizers when they learn that the country strongly supports organic fertilizers. First, we will consider how much investment is required to build a small organic fertilizer factory? How much investment does a set of organic fertilizer production lines require. How is organic fertilizer produced? What equipment does a small organic fertilizer factory need? These issues must be of concern to manufacturers and investors.
How is organic fertilizer produced
The manure organic fertilizer production technology is to add a fermentation bacteria to the livestock and poultry manure and other organic materials, and after about two weeks of composting, it can achieve the purpose of completely deodorizing, decomposing, killing insects, and sterilizing the livestock and poultry manure, which is harmless and commercialized. The manure is then composted to make a powder or granular fertilizer. The technology of the organic fertilizer production line is especially suitable for the processing of livestock and poultry manure in farms, planting bases and concentrated breeding areas.

Small organic fertilizer production line cost
In fact, the cost of small-scale organic fertilizer production projects is still relatively low. The amount of starter used on the raw materials is small, and only 1 kg of starter is needed for fermenting 1000 kg of organic fertilizer raw materials, and only a few tens to three hundred yuan can be invested to produce one ton of organic fertilizer that meets the national standard.
In terms of equipment, the price of a small powdered organic fertilizer production line ranges from $15,000 to $120,000. The cost of a small granular organic fertilizer production line is $50,000-250,000.
Small organic fertilizer production line covers an area
Annual output of 5,000 tons of organic fertilizer granulation production line covers an area of 2,000 square meters, granulation plant area: 600 square meters, and fermentation plant area of 1,400 square meters.
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.
Organic fertilizer compost making
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.
Materials of organic fertilizer composting
Humidity
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.
In general, to get an aerobic compost that decomposes quickly: chopped materials, proper material ratio, correct moisture content, keep turning, and introduce microorganisms. Just check and adjust the five aspects. If you want to know more about composting, you can visit https://fertilizerequipmentmanufacturer.com/compost-fertilizer-making-machine/

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.
Groove type compost turner for sale
1. Pretreatment
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. If you need more detail, you can visit https://fertilizerequipmentmanufacturer.com/compost-fertilizer-making-machine/
The temperature, humidity, PH value and C/N ratio of the compost during the fermentation process are important factors affecting the effect of the compost. The temperature during the fermentation process of organic fertilizer can be summarized as follows: the temperature rises steadily in the early stage, the high temperature in the middle part remains moderate, and the temperature decreases slowly in the later stage, and the temperature control directly affects the maturity of organic fertilizer in the later stage.
Crawler type compost turner for organic fertilizer fermentation
The compost temperature of organic fertilizers is mainly controlled by pile turning and forced ventilation. Here, SX can provide you with processional compost turner. In the early stage of fermentation, even if the temperature of the fermentation is slow or even does not rise, the pile must be turned or ventilated after 48 hours to avoid the formation of an anaerobic environment in the high temperature stage. When the pile temperature is lower than 50°C, the pile should be turned in time (the reduction of oxygen will cause the reaction in the pile to gradually decrease, thereby reducing the temperature), increase the pile temperature, promote the decomposition of organic matter and kill harmful microorganisms. In the late stage of fermentation, once the temperature exceeds 65°C, The pile must be turned in time to prevent carbonization and ammoniation of organic matter. Click here to learn more.
Organic waste compost pile temperatures
During aerobic fermentation, temperature control is very important. If the temperature is too low, the maturity standard will not be met. If the temperature is too high, the nutrients in the compost will be easily lost. The temperature in the compost is within 30 cm from the outside to the inside. Therefore, the metal rod of the thermometer used to measure the temperature must be longer than 30 cm. When measuring, it must be inserted into the compost for more than 30 cm to correctly reflect the fermentation temperature of the compost. In SX, we also have compost machine with temperature monitor on sale, It is in-vessel fermentation tank.
Horizontal fermentation tank for organic fertilizer production
How to read the compost temperature
1. When reading the temperature, make sure the thermometer goes deep into the pile, leave the thermometer for a while to allow the temperature to stabilize before taking the reading, then move it to a new location (including several locations at different depths from the top edge ).
2. The temperature of the pile depends mainly on the moisture content and chemical composition of the raw material components.
3. There is a certain gradient in the change of fermentation temperature. For the system with bottom ventilation, the highest temperature is about 2/3 of the bottom or higher.
The products produced by bio-organic fertilizer equipment are made of fresh chicken and pig manure, without any chemical ingredients. However, chickens and pigs have poor digestibility and can only consume 25% of the nutrients. Feces are discharged, so that the dry product contains nitrogen, phosphorus, potassium, organic matter, amino acids, protein and other components.
Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Fertilizer with fertilizer effect.

1. Advantages of bio-organic fertilizer fermentation process
In the production process of bio-organic fertilizer, it is necessary to effectively control the factors affecting the fermentation of organic waste and the reproduction of microorganisms. The main influencing factors are organic matter content, moisture content, carbon-nitrogen ratio, oxygen concentration, temperature and pH in the composting process On the one hand, through the control of various factors, the carbon-nitrogen ratio, temperature, humidity, pH value, oxygen and other nutrients necessary for the growth and reproduction of various microbial strains are met; on the other hand, different nutrients Fertilizer content can produce different effects. For example, high carbon content can help soil fungi increase, nitrogen can help soil bacteria increase, and calcium has obvious effects on crop disease resistance.
The stench produced by bio-organic fertilizer composting needs to be prevented and controlled to avoid secondary pollution. Adding fermentation agents or fast-decomposing bacteria to the compost can reduce the stench in a short period of time, and the sensory effect is better; or The malodorous gas produced by the composting field is treated with biological deodorization technology.
