Kleemann has unveiled its new MOBISCREEN MSS 502(i) EVO mobile scalping screen designed for high flexibility, simple operability and very good ergonomics.
The MOBISCREEN MSS 502(i) EVO extends Wirtgen brand Kleeman’s portfolio of mobile screening machines below the established MOBISCREEN MSS 802(i) EVO.
The machine can be operated all-electrically, scoring high with regard to sustainability.
With its compactness, the MSS 502(i) EVO is optimised for the lower feed capacity range of up to 350 t/h. A generously dimensioned feed hopper, a screening surface of 5.4 m² and a wide main discharge conveyor guarantee excellent material guidance. For high flexibility in the application, the speed of all conveyor belts is steplessly adjustable and a simple conversion from two to three final grain sizes is possible.
The wide setting range of the screen casing angle (15.4 – 20°) makes a high screening capacity combined with very high product quality possible. The large selection of screening media also contributes to this. Whether these are finger decks for clayey excavated earth or square mesh for classifying decorative grit – from a large selection of screen media, the screen decks of the MOBISCREEN MSS 502(i) EVO can be covered to match the individual application case. Mixed covering of the screen decks is also possible. Overall, the new machine offers comprehensive configuration diversity to impress as a stand-alone or in conjunction with further Kleemann machines to precisely meet the customer’s needs.
The user-friendly operating concept of the MOBISCREEN MSS 802(i) EVO is also used in the MSS 502(i) EVO. Automatic mode for simple and fast production start is also a core element as well as the mobile operating unit, the optional radio remote control and the telematics solution for improved planning and analysis of the machine. A good view of transfer points and the material flow is always possible thanks to LED lighting (optional Premium lighting). Ergonomic access to all screen decks and maintenance-relevant components increases work safety and reduces downtimes.
With its compact transport dimensions and stepless drive control, the scalping screen simplifies transport from one operation site to the next. On site, the interplay between mobile operating device and assembly-free folding out of the discharge belts pays off: Thanks to the joystick control, the operator has a perfect view of the belt to be folded and can move it into position with great precision. This saves unnecessary walking distances and, above all, time.
Apart from the operating concept and material flow, ease of maintenance determines the economic operation of screening machines to a considerable extent. A well-thought-out hydraulic concept on the new MOBISCREEN MSS 502(i) EVO guarantees very high power transmission and lowers the operating costs. Easy access to all maintenance-relevant components, flexible refuelling from both sides and simple, and therefore fast, cleaning of the hopper discharge conveyor undersize through the use of a retractable chute ensure that downtimes are kept to a minimum.
Sustainability plays a decisive role at Kleemann even in the development and design phase. This is demonstrated by the new MOBISCREEN MSS 502(i) EVO where the option of an electro-hydraulic Dual Power drive allows on-site CO₂ emission-free work because the machine can be operated all-electrically. Furthermore, a load-controlled fan guarantees a reduction of the noise level and diesel consumption. Water spraying at the discharge conveyors, in turn, reduces the dust emissions significantly during machine operation and therefore ensures better working conditions for plant operators and higher levels of acceptance of local residents.
