SCREENING

With production efficiency in mind, the new screen comes with a large screening area of about 9,5 m² in the upper deck.

With the new screen, up to four fraction sizes can be produced, three of which are classified exactly.

The MS 953 EVO screen can process up to 500 t of material per hour.

“This is not only an industry-first innovation for the sake of it; it is a major feature improvement with human safety at the core of its introduction,” says Krill. With its easy-to-operate control system via the control panel, handling of the MS 953 EVO is user-friendly and intuitive. A control panel that can be plugged in at three different points, and allows for viewing of the executed function, ensures increased work and operational safety. Safety is as vital in quarries as it is in mines and dust inhalation can be a major problem. With that in mind, an optional belt cover and a water system on the fine grain conveyor significantly reduce dust emission from the screening plant. “The plant comes with an on-board water pump which injects pressurised water into the spray nozzles for dust suppression,” says Newby. Focus on efficiency With the new screen, up to four fraction sizes can be produced, three of which are classified exactly. The MS 953 EVO screen can process up to 500 t of material per hour. With production efficiency in mind, it comes with a large screening area of 9,5 m² in the upper and middle deck. This is complemented by a large feed hoper that allows the MS 953 EVO to 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 8 m³, which opens in the direction of the material flow. The material is conveyed further via the machine’s 1 200 mm wide feeding conveyor. As a result the incline of the belt can be adapted

applications at alternating locations. As it is ready for operation in a short space of time, it can be moved quickly and used flexibly. “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,” says Newby. The compactness and light weight of the screening plant ensure ease of transportation. Measuring in at a compact 3,2 m x 18,60 m x 3,4 m in transport mode, the MS 953 EVO weighs in at 36,3 t. Ease of general maintenance has also been improved, according to Newby. The screen box is easily accessible from all sides, thus enabling simple and quick replacement of the screen meshes. “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 understand- ing 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 ma- chines 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 op- erations, as well as providing continued onsite backup support and training,” con- cludes Newby. b

hydraulically to the material flow,” says Newby. “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 distributes the material evenly on the screen area and thus protect the plant against wear. Efficient screening is achieved with the optimised material flow,” adds Newby. Another key competitive edge of the new arrival is its significant lower fuel consumption. The reduction in fuel consumption is as a result of a combination of factors, but largely due to the transition from a larger Caterpillar engine on the previous MS 19 D, to a Deutz engine on the new MS 953 EVO. Using a 90 kW Tier 3 Deutz engine, the MS 953 EVO consumes between 12 to 16 ℓ of diesel per hour, on average. This is a significant improvement when compared with the previous Kleemann MS 19 D which consumed between 18 and 22 ℓ per hour using a Caterpillar engine. Uptime in mind With its precise classification of different feed materials across a number of applications such as quarries, mining, aggregates, 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. Characterised by short tooling times, particularly good transport and quick setup properties, the screening plant is easy to transport, thus making it ideal for
