Wirtgen South Africa has introduced the new Kleemann Mobiscreen MS 953 EVO triple-deck mobile classifying screen to its southern African customers.
The machine made its international debut at the steinexpo 2017 trade fair in Germany, and its launch follows the recent introduction of the Kleemann MS 703 EVO screen to the same market.
Kleeman says that the MS 953 EVO offers precise classification of different feed materials across applications such as quarries, mining, sand production and recycling, combined with short mesh exchange times, and its classifying screen fits the bill for often nomadic crushing and screening contractors.
Mike Newby, sales engineer, Mineral Technologies at Wirtgen South Africa, says the biggest improvement is the “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,” he says. The MS 953 EVO screen can process up to 500tonnes of material/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.
It can be loaded using a wheeled loader or an upstream crushing plant, and for an optimal material flow Kleemann has developed a feed hopper with a 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. The incline of the belt can be adapted hydraulically to the material flow.
Measuring 3.2m x 18.6m x 3.4m in transport mode, the MS 953 EVO weighs 36.3tonnes, and this is complemented by a generous ground clearance for simple transportation from one site to the other.
Newby says that general maintenance has also been improved, with the screen box 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,” says Newby.
Wirtgen South Africa 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 technicians and process specialists to optimise our clients’ machines and operations, as well as providing continued onsite backup support and training,” says Newby.
