Double screws compost turning machines: The core guarantee for aerobic fermentation process

In modern composting and fermentation processes, whether the materials can achieve sufficient and uniform contact with oxygen is crucial in determining the efficiency of decomposition and the final quality. The double screws compost turning machine, with its unique design and working method, is becoming a key technological equipment to solve this core problem, providing a stable and efficient solution for large-scale organic waste treatment.

The core value of this equipment lies in its excellent mixing and homogenization effect. During the turning process, the double helix structure not only breaks up caked materials but also thoroughly exchanges and mixes the surface and bottom layers, as well as the internal and external materials. This three-dimensional mixing method allows moisture, temperature, and microorganisms to quickly become uniform within the compost pile, greatly improving the stability and controllability of the fermentation process.

In a complete organic fertilizer production line, the double screws compost turning machine is usually deployed in the core section of windrow composting or trough composting. As the “main force” in the entire organic fertilizer production equipment system, it works closely with the front-end system and the back-end discharge system, achieving continuous operation from raw material entry to the completion of primary fermentation, significantly shortening the fermentation cycle and improving site utilization and production efficiency.

With its reliable and efficient performance, the double screws compost turning machine provides a solid process guarantee for the resource utilization of organic waste and the stable production of high-quality organic fertilizer.

What are the characteristics of the materials processed by the new type organic fertilizer granulator?

In organic fertilizer production lines, the core advantages of the new type organic fertilizer granulator are concentrated in its adaptability to different materials and its processing effectiveness. Compared with traditional equipment, it can precisely match organic fertilizer raw materials with different characteristics, while simultaneously preserving nutrients and maintaining product quality during processing, making it a key organic fertilizer production equipment for improving production efficiency.

Its wide range of adaptable materials is a significant feature. Whether it’s common raw materials such as livestock and poultry manure compost and straw powder, or industrial organic waste such as mushroom residue, pharmaceutical residue, and distiller’s grains, the new type organic fertilizer granulator can process them stably. For difficult-to-process materials with high humidity (30%-60%) and high fiber content, it can process them directly without complex pre-treatment, overcoming the strict limitations of traditional equipment on material humidity and fiber content.

It offers strong protection for material nutrients and active ingredients. The new equipment adopts low-temperature granulation or low-pressure molding technology, which can maximize the retention of original nutrients and biological activity in the materials. Especially for bio-organic fertilizer raw materials with added functional bacteria, it can prevent the inactivation of functional bacteria due to high temperatures, ensuring the fertilizer’s effectiveness.

The processed materials have uniform and stable quality. The new type organic fertilizer granulator, through precise control of processing parameters, ensures that the formed material particles are uniform in size, have moderate hardness, are not prone to caking, and have good solubility. This high-quality material processing effect not only facilitates subsequent packaging and storage, but also improves the uniformity of nutrient release during fertilizer application, making it suitable for various fertilization scenarios such as drip irrigation and sprinkler irrigation.

The three core types of fertilizers: Characteristics and applications

Fertilizers are the “nutritional cornerstone” for crop growth, and scientifically classifying fertilizer types is a prerequisite for rational fertilization. Based on their source, composition, and mechanism of action, fertilizers can be mainly divided into three categories: organic fertilizers, chemical fertilizers, and bio-organic fertilizers.

Organic fertilizers originate from animal and plant residues or decomposed waste. Their raw materials include livestock manure, crop straw, distiller’s grains, and kitchen waste, which are fermented and decomposed through organic fertilizer production lines to provide comprehensive nutrients. Organic fertilizers not only contain macronutrients such as nitrogen, phosphorus, and potassium, but are also rich in micronutrients and organic matter. They are characterized by their mild and long-lasting effect, improving soil structure, promoting microbial activity, and enriching soil fertility with long-term use, making them suitable for base fertilization of various crops.

Chemical fertilizers are produced through industrial synthesis or mineral processing and are one of the mainstream fertilizers in modern agriculture. Based on nutrients, they can be divided into nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, and NPK compound fertilizers. NPK compound fertilizers are often precisely formulated and processed by NPK fertilizer production lines, providing single nutrients at high concentrations. Chemical fertilizers are characterized by their fast and direct effect, quickly alleviating nutrient deficiencies in crops and precisely meeting the nutrient needs of crops at different growth stages.

Bio-organic fertilizers, as an important category of high-quality organic fertilizers, can be specially processed by bio-organic fertilizer production lines, better preserving beneficial microorganisms and active ingredients. Their core components can activate fixed nutrients in the soil, inhibit harmful pathogens, and promote crop root development and improve nutrient absorption efficiency. They are characterized by being green and environmentally friendly, and are often used in combination with organic fertilizers and chemical fertilizers to help achieve improved quality, increased efficiency, and sustainable farming.

Unlocking the key to high-efficiency operation of organic fertilizer production lines

The continuous efficiency and product qualification rate of organic fertilizer production lines depend critically on the suitability of the core organic fertilizer production equipment. The drum fertilizer dryer, as the “efficiency hub” of post-processing, not only undertakes the core task of material dehydration but also connects the preceding and succeeding processes, solving bottlenecks and providing crucial support for large-scale production.

Its core value lies in “efficient dehydration + process integration.” After granulation, the moisture content of organic fertilizer granules reaches 20%-30%. If drying is not timely, clumping and mildew can occur, disrupting the process. The drum fertilizer dryer, through the rotation of the inclined drum and the turning action of internal baffles, ensures sufficient contact between the material and hot air for uniform dehydration, precisely controlling moisture content to a safe range of 12%-14%. With a processing capacity of several tons to tens of tons per hour, it is perfectly suited for continuous operation of the production line.

As a key piece of organic fertilizer production equipment, its adaptability is extremely strong. Whether it’s livestock and poultry manure, straw-based organic granules, or organic-inorganic compound granules, it can be adapted by adjusting the hot air temperature and drum rotation speed, preventing high temperatures from damaging nutrients while ensuring effective drying. At the same time, it seamlessly connects with organic fertilizer granulators, coolers, and screening machines, forming a closed-loop process, reducing transportation losses and improving the overall efficiency of the production line.

For large-scale, standardized organic fertilizer projects, the drum fertilizer dryer is a core component for improving overall efficiency. Its stable operation can significantly reduce the rate of product re-moisturization, improve the qualification rate, shorten the production cycle, and contribute to the efficient and low-cost operation of the organic fertilizer production line.

Types of organic fertilizer materials and processing characteristics suitable for rotary drum granulators

The rotary drum granulator, with its strong adaptability to various materials and high granulation rate, has become a core piece of equipment in organic fertilizer production lines. It can process organic materials from multiple sources, covering various fields such as livestock farming, agriculture, and industrial processing.

Livestock and poultry manure is the most common suitable material, including chicken manure, pig manure, cow manure, and sheep manure. These materials are rich in basic nutrients such as nitrogen, phosphorus, and potassium. After fermentation and composting, they have a loose texture and a certain viscosity, which meets the granulation requirements of the rotary drum granulator. The rotating agitation of the drum allows the manure material to be fully mixed with auxiliary materials, resulting in granules with moderate strength, effectively solving the problems of seedling burning and environmental pollution caused by the direct application of livestock and poultry manure.

Agricultural straw materials can also be processed by the rotary drum granulator, such as corn stalks, wheat stalks, and rice stalks. Straw is rich in cellulose and organic matter. After crushing and fermentation, it needs to be used in combination with viscous materials such as livestock and poultry manure. The rolling granulation of the drum allows the straw powder to be evenly coated and formed, which not only increases the organic matter content of the organic fertilizer but also realizes the resource utilization of agricultural waste.

In addition, the rotary drum granulator can also process industrial organic waste materials, such as distiller’s grains, vinegar residue, furfural residue, and pharmaceutical waste. These materials are rich in nutrients, but their composition is complex and their moisture content fluctuates greatly. The rotary drum granulator can adapt to the characteristics of different wastes by adjusting the rotation speed and material ratio, converting them into qualified organic fertilizer granules. At the same time, urban and rural organic waste such as kitchen waste and garden fallen leaves, after sorting and fermentation, can also be granulated and recycled through the rotary drum granulator.

The crucial role of crushing equipment in organic fertilizer production lines

A high-efficiency, stable organic fertilizer production line begins with the meticulous pretreatment of raw materials. While the crushing stage is at the forefront of the entire organic fertilizer production equipment system, it fundamentally determines the quality of subsequent fermentation and the finished product.

Among these processes, the half-wet material crusher demonstrates a unique advantage in handling high-moisture raw materials. It effectively crushes sticky and moist materials such as fresh poultry and livestock manure, kitchen waste, and straw, solving the pain points of traditional crushers, such as easy clogging and low efficiency. Its special anti-stick design ensures that even high-moisture materials can be smoothly broken up, creating ideal physical conditions for subsequent uniform fermentation and rapid decomposition. This is a key link in improving the adaptability of raw materials in modern organic fertilizer production lines.

From the “coarse crushing” of raw waste by the half-wet material crusher to the “fine crushing” of fermented materials by the fertilizer crusher, these two types of equipment form a highly efficient pretreatment combination at the forefront of the organic fertilizer production line. Together, they transform raw materials of varying shapes and moisture levels into materials of uniform specifications that are easy to process, ensuring the smooth operation of the entire production line and the stable quality of the final product.

Therefore, when constructing a complete organic fertilizer production equipment system, paying attention to the crushing process and investing in specialized equipment are indispensable steps to achieve the resource utilization, large-scale, and high-value utilization of organic waste.

Organic fertilizers vs. Chemical fertilizers: A comprehensive analysis of their differences and applications

In agricultural production, organic fertilizers and chemical fertilizers are two core types of fertilizers. They differ significantly in nutrient composition, fertilizer efficiency, and impact on soil. Understanding their characteristics is crucial for their scientific and effective use.

In terms of nutrient composition, organic fertilizers originate from the decomposed remains of plants and animals. After processing through organic fertilizer production lines and shaping by organic fertilizer granulators, they retain the advantage of comprehensive and balanced nutrients, containing macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as calcium, magnesium, and iron, and are also rich in organic matter. Chemical fertilizers are mostly industrially synthesized, with compound fertilizers produced by NPK fertilizer production lines being a typical example. Chemical fertilizers generally have a single, concentrated nutrient composition, usually focusing on one or a few elements, such as nitrogen fertilizers, phosphorus fertilizers, and NPK compound fertilizers, with high nutrient purity.

Regarding fertilizer efficiency, organic fertilizers have a mild and long-lasting effect, with nutrients released slowly after microbial decomposition and absorption by crops, providing long-term nutrition. Chemical fertilizers have a fast and strong effect, with nutrients easily absorbed directly by crops, quickly alleviating nutrient deficiency symptoms. However, their effect is short-lived, and excessive application can lead to nutrient loss.

In terms of application scenarios, organic fertilizers are suitable as base fertilizers, applicable to various crops such as fruits, vegetables, and grains, and are especially suitable for green and organic agricultural product cultivation. Chemical fertilizers are suitable as topdressing fertilizers, used to quickly supplement nutrients during critical growth stages to increase yield. In actual production, a reasonable combination of the two can quickly meet the nutrient needs of crops while also protecting the soil and achieving sustainable farming.

A three-step value enhancement process in organic fertilizer production lines

In modern organic fertilizer production, a complete production line not only needs to complete basic processing but also achieves significant value enhancement through refined processing.

After the materials have completed fermentation and mixing, the fertilizer compaction machine initiates the refined processing journey. It shapes loose powdery materials into uniformly sized granules using physical pressure. This process not only improves the physical properties of the product, making it easier to store and transport, but more importantly, it lays the morphological foundation for subsequent processing.

The extruded granules then enter the screening stage. The fertilizer screener machine, through a precise screening mechanism, strictly grades the finished product according to particle size specifications. Particles that meet the standards proceed to the next process, while products with unqualified particle sizes are returned to the previous process for reprocessing.

At the end of the entire organic fertilizer production line, the fertilizer coating machine plays a crucial role. This equipment effectively reduces clumping during storage by coating the granules with a special film material, while also enabling the slow release of nutrients. Products treated with coating not only have a brighter appearance but also significantly enhanced functionality and added value.

The coordinated operation of these specialized organic fertilizer production equipment demonstrates the high level of precision in modern fertilizer production. From the shaping process of the fertilizer compaction machine to the fine selection by the fertilizer screener machine, and then to the value-added processing by the fertilizer coating machine, each step contributes to the quality of the final product.
