The Sandvik QE440 has been developed to be tough enough to recycle mixed materials, and boasts 40 percent more screening area than its predecessor, the model QE340. Stockpiling conveyors on the QE440 are both wider, and higher, to deal with increased production capacity and to facilitate larger stockpiles.
These units are capable of being fed by large crushers and are ideal for a wide range of applications, including pre-screening and scalping, recycling of construction and landfill waste, and separation of cohesive aggregates.
Traditionally, waste management companies have operated using a simple "management of waste" approach to operating a MRF. Throughput targets and continuous operation (minimal downtime) were the main driving forces. The industry has changed however, and the focus moving forward is now on optimizing system performance and reliability, in conjunction with increasing recycling rates and a drive for a "greener" and more sustainable tomorrow.
When considering the addition of, or upgrade to, an "intelligent" MRF, for municipalities or private operators, the main factors should always be the client's (operator) current requirements, and evolving market needs, which include throughput, reliability, output quality, and adaptability. Equally important is a full understanding of what is really expected from any proposed system. Having an engaged and focused mindset for the project with the client from the beginning, will impact and drive the entire design process. This then impacts the overall project result, through to the productive, efficient, ongoing operation of the facility itself.
