Kleemann Uses Three Different Drive Concepts
Kleemann uses three different drive concepts to offer a solution for the task at hand. The decision on the most efficient solution depends on many factors: For example, whether there is a power supply option available on site, whether the machines are used in an urban environment or which local environmental regulations apply.
The E-DRIVE concept offers two options: Diesel fuel or all-electric. All-electric operation is considered environmentally friendly with no CO2 emissions on site. A precondition for this is a good power infrastructure, which is often available in quarries or in larger recycling yards. If the power supply is insufficient or not available, a diesel-electric work option is available. In this case, power comes from the fuel-efficient diesel engine. The crusher and all conveyor belts are then still driven electrically by a generator. Depending on the local situation, the E-DRIVE concept offers high flexibility.
The diesel-directdrive D-DRIVE provides power directly from the engine to the crusher. In the last few years, it was possible to reduce consumption, for example, through the load-dependent fan drive of the new EVO2 Generation.
Mobile screening plants from Kleemann use a diesel-hydraulic drive—the H-DRIVE. In this case, hydraulic pumps operate all machine parts such as screen, belts and drive system. The power requirements of the screens are considerably lower than a crusher—fuel consumption during operation is therefore more favourable. The optionally available Start-Stop system can reduce consumption even more. With the configuration with Dual Power, Kleemann screening plants have an option for an all-electric power supply. If a mains connection is available, the plant operates on site free of emissions – for example, in ecologically sensitive areas with strict regulations.
Many factors play a role in the area of sustainability. Energy required for production, transport, storage, sales and disposal are all incorporated in the ecological footprint of the production process. As far as CO2 emissions during operation are concerned, an all-electric plant is without doubt the best choice, according to the manufacturer. In other cases, you have to weigh up whether supply via an external power source involving high equipment and material costs is more constructive at the end of the day than technology with lower fuel consumption. Ecology can also mean placing your trust in low material usage and high durability.
