In fields such as agricultural waste resource utilization and organic solid waste treatment, large wheel compost turners are an indispensable core piece of equipment. With their highly efficient material turning capabilities, they inject crucial power into the composting fermentation process, rapidly transforming organic matter into high-quality fertilizer.
By definition, a large wheel compost turner is a mechanical device with a "large-diameter disc" as its core working component, specifically designed for turning and mixing materials in a compost pile. It is widely used in the aerobic composting treatment of organic materials such as livestock and poultry manure, straw, kitchen waste, and garden waste. Compared to traditional small compost turners, it boasts a larger operating radius and stronger power output, adapting to the operational needs of large-scale composting sites and solving the industry pain point of difficulty in uniformly turning large-area compost piles.
Its core structure revolves around the "disc": the machine body is equipped with 1-2 large discs with a diameter of 5-10 meters, with high-strength teeth evenly distributed along the edges of the discs. Below, it features an adjustable-height walking device (tracked or wheeled). The machine body also integrates the power system, hydraulic control system, and operating platform. During operation, the equipment moves to the side of the compost pile via a walking device. A hydraulic system drives the rotating disc to spin at high speed, with the teeth penetrating deep into the pile to turn the bottom layer of material to the surface and press the surface material back into the bottom layer, simultaneously crushing, mixing, and loosening the material.
This operating method offers three core advantages: First, it enhances oxygen supply. The turning process breaks up the compacted layer of the pile, allowing air to fully penetrate the material, meeting the respiratory needs of aerobic microorganisms and accelerating the decomposition of organic matter. Second, it balances temperature and humidity. Through material exchange, it avoids fermentation stagnation caused by excessively high local temperatures or humidity, ensuring the entire pile is in an optimal fermentation environment. Third, it increases efficiency. A single unit can process 300-800 cubic meters of material per hour, more than 50 times the efficiency of manual turning, significantly reducing labor costs for large-scale composting.
Today, large wheel compost turners have become standard equipment in ecological farms, organic fertilizer production plants, and waste treatment plants. It not only promotes the "reduction, harmlessness and resource utilization" of organic solid waste, but also provides important technical support for the green development of agriculture, making the "turning waste into fertilizer" circular economy model more efficient and convenient to implement.
