Compost turning machine: The core equipment for large-scale aerobic composting

In large-scale organic fertilizer production systems, the compost turning machine is a key piece of equipment supporting the efficient operation of aerobic fermentation. The core requirement of aerobic composting is to decompose organic waste through the aerobic metabolism of microorganisms, converting it into stable humus. This process has strict requirements for oxygen supply, material uniformity, and temperature and humidity control. Compost turning machines achieve multiple functions through mechanized operation, including windrow ventilation, material mixing, and precise temperature and humidity control. This not only significantly improves fermentation efficiency but also guarantees compost quality, serving as an important bridge connecting organic waste resource utilization with the production of high-quality organic fertilizer. It is widely used in large-scale farms, agricultural waste treatment centers, and organic fertilizer production enterprises.

Aeration and oxygen supply are the most critical functions of the compost turning machine, directly determining the success of aerobic fermentation. The metabolic activity of aerobic microorganisms depends on sufficient oxygen. If the oxygen supply is insufficient, the compost pile can easily enter an anaerobic state, which not only slows down the decomposition rate but also produces malodorous gases such as hydrogen sulfide and methane, polluting the environment and reducing compost quality. The turning machine uses hammers, augers, and other components on the rotating drum to turn the compost pile, forcing air into the gaps between the materials and simultaneously expelling harmful gases from inside the pile, creating a beneficial gas circulation. Different models of turning machines have different emphases on aeration efficiency. The drum speed of the gantry-type turning machine is adjustable, usually controlled at 20-30 revolutions per minute, allowing for adjustment of the aeration depth according to the d
