In the fermentation stage of organic fertilizer production, turning the compost pile is a crucial step determining fermentation efficiency and fertilizer quality. For many organic fertilizer producers, “how to easily turn the compost pile” has long been a core concern, and the emergence of the Double Screw Compost Turning Machine provides an efficient solution to this problem. So, what is a double screw compost turner? And why can it achieve easy turning?
The double screw compost turner is a core piece of equipment specifically designed for organic material fermentation. Its core feature is its double screw structure, where two symmetrically distributed screw shafts work together to mix and turn the materials. Compared to traditional turning equipment, it breaks through the limitations of a single structure, achieving highly efficient material turning through the unique design of the screw blades. Its working principle is not complicated: when the two spiral shafts rotate at high speed, the spiral blades lift the material at the bottom upwards and tumble it to both sides. The entire process requires minimal manual intervention, completing large-scale material turning operations and fundamentally solving the problems of time-consuming, labor-intensive, and inefficient traditional turning methods.
To achieve easy turning, both the equipment’s structural design and performance advantages are indispensable. The double-spiral compost turner’s easy turning capability stems first from its collaborative double-spiral structure. Compared to single-spiral turners, the double-spiral design offers a wider turning range and more uniform mixing, effectively breaking up material slabs and preventing localized material accumulation and insufficient fermentation. Secondly, the equipment is equipped with a flexible adjustment device that allows for flexible adjustment of the spiral shaft height according to the material pile height and the distance between the two shafts according to the material characteristics, ensuring that the spiral blades fully contact the material. Even materials of different types and moisture levels can be smoothly turned. Furthermore, the equipment’s walking mechanism allows for flexible adjustment of forward, backward, and turning movements. The walking speed can be adjusted between 0.3-2 meters per minute according to fermentation needs, adapting to different operational requirements in windrow or trough fermentation sites, further enhancing the ease of turning.
It is worth noting that the double-helix compost turner’s easy turning does not come at the expense of fermentation efficiency. During the easy turning process, the material is fully dispersed, significantly increasing the contact area with air, effectively regulating the material’s temperature and humidity, creating a suitable environment for microbial growth and metabolism, thereby accelerating the material’s maturation and fermentation. Whether it’s livestock manure, crop straw, industrial organic waste, or municipal organic waste, all can achieve efficient fermentation through its turning operation. For medium to large-scale organic fertilizer production enterprises, the application of this type of equipment not only reduces the labor intensity of the turning process but also improves fermentation efficiency and shortens the fermentation cycle, laying a solid foundation for large-scale production.
A Foundational Technology in the Organic Fertilizer Value Chain
The double screw compost turner is a prime example of advanced fermentation composting turning technology, designed to solve the core challenge of efficient aeration and mixing in organic waste processing. As a highly effective self propelled compost production machine, its ease of use and high efficiency make it a cornerstone for scalable organic fertilizer production.
This type of turner is part of a larger family of solutions, which also includes the trough-type compost turner for controlled trough-type aerobic fermentation composting technology, the large wheel compost turner for wide windrows, and the chain compost turner for deep piles. The high-quality compost produced by these machines is the essential raw material for the subsequent equipments required for biofertilizer production. This mature compost can be precisely formulated using a single silo single weigh automatic batching system and then shaped into a marketable product. The final granulation can be achieved through processes like drum granulation or by using a complete disc granulation production line, transforming the bulk organic matter into uniform fertilizer granules ready for distribution.
Ultimately, by mastering the initial, critical fermentation stage with equipment like the double screw turner, producers create a consistent and stable organic base, enabling the entire downstream value chain for commercial biofertilizer manufacturing.
In summary, the double-helix compost turner, with its unique double-helix structure, flexible adjustment functions, and efficient collaborative operation mode, perfectly answers the industry challenge of “how to easily turn compost.” It is not only a highly efficient piece of equipment in the composting and fermentation process, but also promotes the large-scale development of organic waste resource utilization, providing strong support for the development of ecological agriculture.
