High performing mobile scalping solution developed for fines separation
Sandvik Construction Mobile Crushers and Screens is pleased to announce a new addition to its scalper range with the introduction of the NEW QE441 Free Flow. A versatile and highly efficient solution for processing difficult to screen materials & products with high moisture contents.
Our new QE441 Free Flow provides you with a versatile and highly efficient mobile solution for handling sticky, moist and wet materials with a high percentage of fines. It is your ideal solution for processing materials such as soils, aggregates, ores, waste, biomass and other waste derived fuels including products with high moisture contents.
We have designed this unit based on the sturdy crusher-style chassis of our class leading QE441, combined with a highly productive and aggressive double deck Free Flow screen. The heavy duty scalping screen allows you to process large un-screened material on the rigid scalping top deck, whilst providing a fine screening solution on the dual motion lower deck. The powerful snapping of the bottom deck media generates an active “flip-flow” movement which generates a huge throw that propels material upwards and outwards separating material as it does so and thereby eliminates any plugging and blockages. This results in the processing of more sellable products and less waste.
The QE441 Free Flow has been designed with the same user-friendly features of our 1-Series screens. These include Sandvik’s easy to use control system and user interface with sequential start, whilst two speed tracking will help to reduce travel time between jobsites. The QE441 Free Flow offers increased plant durability and operator comfort, without sacrificing on performance.
With a large choice of screen media and a wide range of adjustable throws and speeds available, this enables the QE441 Free Flow to be configured to suit the specific requirements of the application. It compliments our Premium jaw crushers and QI341 Prisec™ impact crusher and can also work as a stand-alone unit.
