The basics of large-scale compost turners

Compost turners come in a variety of sizes and designs, but they all have the same basic components. At its core, an industrial compost turner is made up of a large rotating drum or auger that agitates the compost pile. This mechanical turning action serves several purposes.

  • First, it is vital to evenly distribute moisture throughout the pile. Moisture is essential for the composting process, but without proper distribution, some areas of the pile may become too dry or too wet.
  • The turning action also helps to aerate the compost pile, allowing oxygen to reach the microorganisms that break down organic matter. These microorganisms require oxygen to thrive and efficiently decompose the waste.
  • Turning the compost helps regulate the temperature of the compost pile as well. A crucial factor is heat because is necessary for the decomposition process and for killing pathogens and weed seeds.
  • As the drum or auger rotates, it helps to mix the different types of materials within the compost pile. This is important as composting requires a precise mix of carbon-rich (browns) and nitrogen-rich (greens) materials. A proper balance of these materials is necessary for the microorganisms to thrive and break down the organic matter efficiently.
  • Finally, the turning action also helps to break down larger pieces of organic matter into smaller, more manageable pieces. This speeds up the decomposition process and helps to create a more homogeneous compost.

Advantages of industrial compost turners

The use of an industrial compost turner offers many advantages over traditional methods of composting. 

  • One major advantage is that your operation can function more efficiently. In large-scale operations, a compost turner can process much more material in less time compared to manual turning or windrow turning methods.
  • Industrial compost turners also create a more consistent and uniform product. This is important for commercial compost producers who need to meet specific quality standards for their customers.
  • With the ability to aerate and mix the compost pile more efficiently, industrial compost turners can significantly reduce the time required for the whole composting process, increasing your overall productivity.
  • Another significant advantage of using an industrial compost turner is that it can help to eliminate odors and control pests. Properly aerated and mixed piles are less likely to produce unpleasant smells.

Types of compost turners

Industrial compost turners come in different sizes and configurations depending on the specific needs of each operation. Some common types include:

Drum Turners

Drum turners are the most common type of industrial compost turner. They consist of a large drum that rotates around a horizontal axis. The drum is usually fitted with paddles or flails to agitate and mix the compost pile as it turns.

Auger Turners

Also known as windrow turners, these machines use an auger to lift, turn, and aerate the compost pile. Auger turners are ideal for larger operations that produce more than 10,000 tons of compost annually. They work best with longer, windrow-style compost piles.

Elevating Face Turners

These turners are best suited for large, horizontal compost piles. They have a long arm with paddles that lifts and turns the pile as it advances forward.
