The Working Principle of Windrow Compost Turner


In the field of organic waste management, windrow composting has gained significant recognition as an efficient and environmentally friendly technique. At the core of this process lies the windrow compost turner, a vital tool that plays a crucial role in decomposing organic matter and producing nutrient-rich compost. In this blog post, we will delve into the working principle of the windrow compost turner, exploring its three key functions: piling materials into strips, composting over materials, and observing and adjusting during composition.

1. Piling Materials into Strips

The first step in the windrow composting process is to pile the raw organic materials into long strips called windrows. This is where the windrow compost turner excels. Equipped with a specialized turning drum, the machine efficiently collects the organic waste and forms it into well-structured windrows. Through a continuous self-propulsion mechanism, the turner evenly distributes the materials, enabling effective aeration and moisture retention.

2. Composting Over Materials

Once the materials are properly stacked, the windrow compost turner initiates the composting process. It accomplishes this by systematically turning the windrows at regular intervals. As the turner moves along the windrows, the organic matter is constantly mixed, ensuring homogenous composition and enhanced air circulation. This not only promotes the decomposition process but also prevents the formation of anaerobic zones, which could hinder the composting process.

As the turner continuously flips the windrows, it creates a turning effect that introduces oxygen to the organic matter. This oxygen-rich environment facilitates the growth of beneficial microorganisms, such as bacteria and fungus, which are essential for the breakdown of complex organic compounds into simpler, more stable compounds. Moreover, this turning action assists in heat distribution, ensuring that the core temperature of the windrow reaches the optimal range for accelerated decomposition.

3. Observing and Adjusting during Composition

To ensure optimal composting conditions, continuous monitoring and adjustment are vital. A modern windrow compost turner is equipped with advanced sensing technologies to gauges crucial parameters such as temperature, moisture content, and oxygen levels. These indicators provide valuable insights into the progress of the composting process.

Based on the data collected, compost operators can make informed decisions on the adjustment of turning frequency, watering, and material ratios. This enables them to maintain an ideal environment for microbial metabbolism, guaranteeing an efficient breakdown of organic matter into nutrient-rich compost.

The windrow compost turner undoubtedly serves as the backbone of the windrow composting process. Through its functionalities of piling materials into strips, composting over materials, and observing and adjusting during composition, the turner ensures proper aeration, homogenized mixture, and optimal conditions for microbial growth. By harnessing the capabilities of this essential machinery, organic waste producers can capitalize on the benefits of windrow composting, contributing to sustainable waste management and the production of high-quality compost.
