Wirtgen SA, local subsidiary of the Wirtgen Group has launched the much anticipated Kleemann Mobiscreen MS 703 EVO to the South African market.
Developed and designed in Germany, the Kleemann MS 703 EVO is a triple deck mobile classification screen that precisely screens out almost all types of coarse natural stone, residual construction materials and iron particulates of up to 150mm up to four fractions.
Finding application in both the mining and construction sectors, this plant screens out material after the initial crushing process and offers superior performance, fuel efficiency and intuitive handling.
Measuring in at 1.520m x 4.440m with a 75kW engine and with a feed capacity of 350t/h, the MS 703 EVO comes with either diesel-hydraulic or diesel-electric drive as well as a large number of screening media to achieve a variety of final grain sizes and to take different feed material.
Thanks to a generously proportioned screen casing, material is well-distributed across the screen surface and its built-in peripheral platform means the screening plant is easily accessible for maintenance and screen media changing.
The plant boasts a large feed hopper which can readily accept feeding by means of a wheel loader, an excavator or directly from a crushing plant. Both folding and vibration gates are optionally available. The plant also has a special space-saving transport position, so that the most compact dimensions can be achieved should the plant be required to move to a new site; this is complemented by quick set-up times and fast screen media change capability.
Classifying screens
The Mobiscreen series comes with classifying screens that are renowned for their inherent flexibility, which contributes to optimal functioning and resultant output values. Suitable for a host of applications, the MS 703 EVO’s adaptability is made possible by the variety of available screen casing sizes as well as the ease and speed with which it can be transported.
Screening media on a classifying screen plant are put to the test on a daily basis and are manufactured from a special wear-resistant spring wire steel or round wire to withstand the workload and to produce consistently accurate results. Double bracing at intersections makes for high mesh stability, and therefore uniform screening, a possibility which is also influenced by grain shape, moisture content as well as the loaded volume.
Mesh shapes and dimensions
Square mesh screen surfaces are the most common and are predominantly used in applications where a cubic shape is required. Different wire qualities and thicknesses are available: the thicker the wire, the longer service life it will have; the thinner the wire, the higher production it will ensure.
Rectangular mesh screen surfaces are for screening cubic grain sizes and are often used to sort natural gravel at high throughput.
The Harp screening media are used for screening damp material and difficult screening products. They boast a self-cleaning mechanism through the natural vibration of the longitudinal wires and should be inserted at the lower deck of the screen. The harp screen surface is available in different versions, including W-harp, S-harp, and Varia harp.
With fast set-up time, operator-friendly design and cost-saving features, the Mobiscreen MS 703 EVO is backed not only by Kleemann’s exacting standards, but by fully qualified service technicians available 24 hours a day as well as all recommended spares available at Wirtgen SA’s Pomona offices.
