In large-scale organic fertilizer production lines, compost turning efficiency is key to determining production capacity. The large wheel compost turner, with its unique design and powerful performance, has become the core equipment for improving compost turning efficiency, completely changing the inefficient situation of traditional composting operations.
Its high-efficiency turning capability stems primarily from the superior performance of its core components. The large disc at the core of the equipment has a diameter of 5-10 meters, far exceeding that of conventional equipment. Its edges are spirally or radially distributed with 30-60 cm long wear-resistant alloy teeth, allowing a single rotation to cover a wider working area. The maximum turning depth reaches 2 meters, enabling the turner to flip both layers of material in one operation, avoiding the repetitive work of layered turning. The rotary disc rotation speed can be precisely controlled at 10-20 revolutions per minute, coupled with a walking mechanism adjustable in speed from 0.2-1 meter per minute, achieving synchronous "turning-movement". A single unit can process 100-200 tons of material per hour, which is 3-5 times that of a tracked compost turner, with a daily processing capacity of 500-1000 tons, efficiently adapting to large-scale production needs.
The high efficiency of turning is also reflected in the significant reduction of the fermentation cycle. Traditional turning equipment is prone to uneven material mixing and insufficient oxygen supply, resulting in a lengthy fermentation cycle. The large wheel compost turner, however, uses the centrifugal force generated by the rotating disc to scatter the material from the bottom upwards and to both sides before re-piling it, ensuring full contact between the material and air. The temperature distribution difference within the pile is ≤2℃, avoiding uneven local fermentation. During fermentation, efficient turning can be achieved when the initial temperature reaches 50-60℃. During the high-temperature period (60-70℃), turning is required every two days to kill pathogens, and during the cooling period, turning is required every 3-4 days to promote humus formation. The entire fermentation cycle takes only 20-30 days, significantly shorter than traditional methods, indirectly improving overall production efficiency.
In practical applications, the efficiency advantage of the large wheel compost turner significantly reduces costs. Taking a 10,000-ton-per-year organic fertilizer production line as an example, the equipment is highly automated, requiring only 1-2 people to operate a single unit, reducing labor costs by 50%-70% compared to traditional equipment. Simultaneously, its unit material energy consumption is low, resulting in operating costs 20%-30% lower than traditional equipment. When processing various organic raw materials such as livestock and poultry manure and crop straw, it can quickly break up clumps and regulate temperature and humidity, ensuring stable and efficient large-scale production, becoming a highly efficient tool for promoting the resource utilization of organic solid waste.
