Having recently rolled off the Kleemann production line in Germany to make its official international debut at the recently ended
With its precise classification of different feed materials across a number of applications such as quarries, mining, sand production and recycling, combined with short mesh exchange times, the new Kleemann MS 953 EVO classifying screen fits the bill for often nomadic crushing and screening contractors.
While new features abound on the new classifying screen, Mike Newby, sales engineer – Mineral Technologies at Wirtgen South Africa, explains that the biggest improvement is the innovative, industry-first safety feature that allows the entire machine to be moved, unfolded and operated via a user-friendly, mobile control panel, which can be plugged in at three different points on the screening plant. “Operators no longer need to stand right next to the machine to pull levers to unfold the conveyors. All folding and lowering functions can be viewed and performed remotely, enhancing safety for the plant operator,” says Newby.
The MS 953 EVO screen can process up to 500 tonnes of material per hour with a screening area of approximately 9.5m² in the upper deck. With the new screen, up to four fraction sizes are produced, three of which are classified exactly. The MS 953 EVO can be loaded using a wheel loader or an upstream crushing plant. For an optimal material flow, Kleemann developed a feed hopper with a very large load capacity of 8m³, which opens in the direction of the material flow. The material is conveyed further via the machine’s 1,200mm wide feeding conveyor. As a result the incline of the belt can be adapted hydraulically to the material flow.
The screening angle of the screen box can also be varied depending on the application. Impact plates are installed at the belt discharge and the screen box feeding, which distribute the material evenly on the screen area and thus protect the plant against wear. Efficient screening is achieved with this optimised material flow.
Due to frequent changes in work sites for contractors, the new Kleemann MS 953 EVO screen was designed with the understanding that a space-saving transport position and short setup times are highly significant. This is complemented by the quick change of screening media to react to different material requirements in the shortest possible time.
The compactness and light weight of the screening plant ensure ease of transportability. Measuring in at a compact 3.2m x 18.6m x 3.4m in transport mode, the MS 953 EVO weighs in at 36.3tonnes, and this is complemented by a generous ground clearance for simple transportation from one site to the other. “The screening plant is easy to transport, thus making it ideal for applications at alternating locations,” says Newby.
With uptime in mind, ease of general maintenance has also been improved, according to Newby. The screen box is easily accessible from all sides, thus enabling the simple and quick replacement of the screen surfaces. “All other surface components can also be reached from the ground or the surrounding platform for uncomplicated maintenance work,” adds Newby.
With Wirtgen South Africa’s understanding that a good product is one thing, and being able to offer crucial aftermarket support to customers is quite another, the company has trained and specialised in-house Kleemann technicians and field service personnel who look after the machines in the field. “On top of this, regular visits to sites are arranged for Kleemann GmbH technicians and process specialists to optimise our clients’ machines and operations, as well as providing continued onsite backup support and training,” concludes Newby.
