The Sandvik SR roller screen in action
Key features of the SR roller screen (Fig. 1), which was specially developed to handle wet materials such as limestone, marl, clay, gypsum rock as well as chalk, slate, coal and lignite, is its compact design, easy handling and excellent engineering, which guarantee constant screening performance even in the severe conditions of the winter months. Conventional screens blind over time, leading to downtime in the cleaning process or unwanted different screened grain sizes. The Sandvik SR roller screen, on the other hand, ensures non-clogging operation and is designed for pre- and intermediate screening of large volumes of low-abrasive materials. It is available in 12 standard models with sizes ranging from 1200 x 2000 mm to 2400 x 6000 mm.
Since commissioning of the plant in September 2009, the Sandvik SR roller screen has operated very efficiently (Fig. 2). The maximum throughput of the plant is 100 t/h. Limestone in sizes up to 60 mm is fed over the entire width of the roller screen. It is cut at 15 mm, that is fine and flaky material < 15 mm is screened off. The cleaned material stream of limestone in the size 15/60 mm is then fed to the kiln.
