In order to produce a product that is top quality, compost must have proper moisture content, temperature, and oxygen concentration. Using equipment called compost windrow turners refreshes the oxygen concentration and makes the mixture consistent all through the material. These machines also help with temperature control, and sometimes help with the addition of moisture to your product. Finding the right windrow compost turners for your operation is essential.
What do compost turners do?
While compost windrow turners work to mix oxygen and moisture into the compost, they also cool it down. Temperatures over 65 degrees celsius can damage or kill microorganisms that are key to producing high-quality compost. If the temperature of the mixture is too cool, turning it can add oxygen and might be helpful with re-establishing pore space. You may have to turn your compost once or twice a week to cool it down properly.
Rotating drum windrow turner
This is the most common type of windrow turner and can turn windrows that are 1-2 meters high by 3-4 meters wide. They are built with a wide selection of equipment which includes solid flails (in an auger configuration) and augers. The flails draw material from the outside of the windrow while they lift compost material and throw it backward.
The rotation rate of the drum can be measured variably from 150 to 800 rpm and speed, depending on the machine. Some rotating drum turners have nozzles attached to apply water to the compost while it is being turned. To prevent material from being thrown from the windrow, there is a protective shield connected to the rotating drum.
This type of compost windrow turner can be either pulled or self-propelled. Pull-type are driven by a hydraulic motor or a tractor. If there is a breakdown, it is easy to remove the machine from the windrow. Many self-propelled models, like those with hydraulics, can move smoothly over a variety of terrains and are known for their reliability.
Consider these factors when buying a compost windrow turner
It can be difficult to choose a windrow turner because of the wide range of machines available on the market. Each model has different features based on the conditions under which it will be used. You can also get a custom made windrow turner for your specific operational needs. You can consider many features to help you purchase the best compost turning machine for your needs. These include horsepower, the processing system or turning mechanisms, the ability to adjust height, and how the turner will affect the quality of your product.
Take into consideration the current industry trends as well. All composting operations are unique, so your equipment needs will be unique as well. Manufacturers of composting equipment are moving away from standardized equipment and toward custom built machines and leasing options. Be sure to ask about your options for buying compost windrow turners before making a purchase.
