The Wirtgen-owned German manufacturer says the new MOBISCREEN MS 1202 and MS 1203 mobile screens are designed to guarantee the effective screening of large volumes of material.
They are available with two or three screen decks and have screening surface areas of 12m² in the upper and middle deck and 11m² in the lower deck, making hourly outputs of up to 750 tonnes possible.
Aiko Fischer, product manager for screening plants at Kleemann, says that the material flow in the new screens has had to be well designed to achieve the high outputs. The feed hopper has been generously dimensioned with a holding volume of 10m³.
"This makes feeding both with a crushing plant as well as with a large wheel loader possible," Fischer adds. "Despite discontinuous feeding by the wheel loader, the large hopper volume ensures continuous material supply to the screen. Correspondingly wide feeding and discharge conveyors guarantee an unobstructed material flow over the screen. The high-torque diesel engine also ensures that the plant does not 'run out of steam'."
Both screens can be combined with the crushing plants from the Kleemann EVO series as well as the PRO series. "The smaller the separating cut and the higher the required final product amount, the larger the screening surface must be. It's really quite simple," says Fischer.
As with other screening plants in the MOBISCREEN series, the MS 1202/MS 1203 are driven by powerful hydraulic power units. The Dual Power option allows the screens to be driven by electric power only, which is designed to further increase the efficiency and reduce the load on the environment by decreased noise and exhaust emissions.
