technology The MS 703 EVO can readily accept feeding by means of a wheel loader or excavator, or directly from a crushing plant. and can readily accept feeding by means of a wheel loader or excavator, or directly from a crushing plant. The feeding height to the slotted grate is about 3.6m. The feed hopper is available in two sizes — 8m 3 or 10m 3 — and can operate with or without the folding grate,” said Van der Merwe. Available with either a diesel-hydraulic or diesel-electric drive, the MS 703 EVO’s dual power option allows for the use of external power, with the 75kW Deutz engine using an average of 10–12 litres per hour. The material is conveyed to the screen box on the extra-wide feeding conveyor of 1 200mm, with a screening angle that can be adapted to the application. “The robust impact plate on top of the feed conveyor ensures that the material is evenly distributed on the screen surface, keeping wear to a minimum and guaranteeing a high throughput. The screen media can be easily changed thanks to both the wedge system and the easily accessible maintenance area,” Van der Merwe added. The plant screens out material after the initial crushing process and offers superior performance, fuel efficiency, and intuitive handling. The large number of screening media allows the plant to achieve a variety of final grain sizes and to take different feed material, while its generously proportioned screen casing ensures that material is well distributed across the screen surface.
