The Kleemann brand of the Germany-based Wirtgen Group says its new Mobicat MC 110(i) EVO2 jaw crusher and Mobicone MCO 90(i) EVO2 cone crusher include a direct drive system offering “a holistic drive concept that forms the basis for high cost-effectiveness.”
“Both machines of the new EVO2 generation are equipped with a patented power train,” Wirtgen Group says. “The crusher is driven directly, and thus with high fuel efficiency, via a reliable fluid coupling."
To reduce dust, the machines are equipped with water nozzles as standard at the crusher inlet and crusher discharge conveyor, along with “the corresponding technical infrastructure,” the company says.
“Optional belt covers also contribute to an improvement [in] air quality during crushing,” Wirtgen Group adds. The measures have been designed to benefit the machine operator, the further peripheral devices on the work site, local residents and the environment, states the company.
Conveying components, such as the vibrating feeder, the double-deck prescreen and the discharge conveyors, are electric powered. “It not only operates with a high level of efficiency but also has ideal protection against dust; downtimes can be avoided to a large extent,” Wirtgen says of the new Kleemann models.
Operation in an ECO mode can additionally reduce fuel consumption as well as wear in idle phases, Wirtgen Group says.
Regarding the new drive concept, “the speed of the cooler fan and thus also the cooling capacity is controlled automatically, which considerably reduces the noise level,” the company says. “Apart from less dust penetration thanks to a lower volume of moved cooler air, work near to the machine is a lot more agreeable for the operator."
For the Kleemann Mobicat MC 110(i) EVO2 jaw crusher, which the company says is frequently used in urban environments, an optional noise protection package is also available. The “considerably reduced noise level” resulting “would even permit work without special ear protection – depending on the material to be processed, further environmental conditions and local regulations,” Wirtgen Group says.
