For separating the nutrient-rich material—compost, mulch and soils—trommel screens play a pivotal role for optimizing production. There are several factors to consider when choosing the right model for a facility. By Duwayne Bonhorst
Communities throughout the U.S. are implementing recycling programs to extend the life of the nation’s waste management facilities. Green waste programs have been a centerpiece of those efforts for decades. However, until recently, many green waste programs have only focused on collecting yard and wood waste material efficiently, with the majority of profits coming from disposal costs. Today, savvy green waste facilities are flipping that old business model by incorporating technology and science to create renewable energy and nutrient-rich organic material that can be sold at a premium price
For separating the nutrient-rich material—compost, mulch and soils—trommel screens play a pivotal role for optimizing production. There are several factors to consider when choosing the right model for a facility: • Desired production rates • Machine design • Customization • Support from the manufacturer and dealer
Production rates can be affected by machine design. Trommel screens are engineered to size material. Smaller material (fines) falls through the screen, while larger material (overs) gets pushed out the back. Along with facility location and the type of material being processed, the machine design is just as important as its size when it comes to swapping out screens or drums and performing routine maintenance
To begin choosing the right size trommel screen for an operation, start looking at the screen size. Most operations are looking for screens between an 1/8 inch to 3 inches (.3 cm to 7.6 cm), and production rates can vary greatly depending on size selected. Smaller screens produce a finer material for reselling. A company that is producing soil will have substantially more overs than if they are producing mulch and require a lot more material to be run through the screen to amass the same volume of end product
Design Considerations Thinking about where a trommel screen will be working is also essential for selecting the right model. Some models will have conveyers off to the side while others are designed with conveyers only off the front and back. Space becomes a factor for companies with smaller yards, which is pretty common when working in an urban environment. For these locations, a trommel screen with a conveyer out to the side may be a better fit. For similar production rates on larger, more open yards, the Vermeer TR626 trommel screen with its 6-foot (1.83 m) drum and ability to be outfitted with a 180-degree arc radial stacking conveyor to increase the amount of material being stacked on the ground should also be considered. Other machine design considerations include the hopper dump height, operator controls and ease of serviceability
