Advantages and infrastructure requirements
Mobile crushing and screening plants that are operated with electricity instead of diesel fuel are regarded as more environmentally friendly because they do not emit CO₂ on site. They are also ahead in terms of cost-effectiveness in the long term. Sustainable, low-emission solutions are in demand. With electrical mobile plants, companies can position themselves on the market as future-oriented providers. Although the initial investment costs are higher, they are quickly amortised due to the fuel savings. A sample calculation for the German market shows that this is already possible after around six years – if the plant can be supplied with energy via the customer's own photovoltaic system, even after around four years.
“Our mobile plant train in the sample calculation consists of a jaw crusher MOBICAT MC 120 PRO, cone crusher MOBICONE MCO 110 PRO as a secondary crushing plant and a downstream screen machine MOBISCREEN MSC 953 EVO. The plant train consumes an average of approx. 77 litres of diesel fuel per operating hour. In the electrified version, it has an average fuel consumption of 302 kW per operating hour. The maximum power requirement is 542 kilowatt”, says Tobias Böckle, head of Product Management at Kleemann. ”The energy requirement must first be met by the infrastructure and, ideally, by electricity from renewable energy sources. The power supply from the company's own photovoltaic system is sustainable and a very fast cost-efficient solution,” says the expert.
”Particularly in combination with its own PV system, electrical operation becomes a climate-friendly, cost-efficient concept in just a few years, which not only provides the operating company with monetary benefits, but also reflects its efforts towards greater sustainability.”

It is also important to consider where the main distribution is located on the site and where the plant will be used. Good planning here is the prerequisite for efficient operation. An example: The electrical energy required to supply the plant is not transformed to low voltage directly at the transfer station, but is instead routed over the medium-voltage level across the site to the plant. The cable cross-section can therefore be much thinner, making the cable more manageable and significantly cheaper. At the mobile plant, a second transformer converts the current into low voltage in order to operate the mobile crushing or screening plant. The aim here is to develop a suitable individual concept.
With a solid foundation, the investment costs are amortised after around six years - or even sooner, depending on the energy concept. From this time on, all-electric operation will save considerable operating costs year after year.
Here is an overview of the switch to electricity as an example.
In many cases, climate protection requirements lead to increased demands. The electric drive is a decisive competitive advantage, for example when local authorities demand emission-free operation in city centres. ”Especially in combination with your own PV system, electrical operation becomes a climate-friendly, cost-efficient concept in just a few years, which not only provides the operating company with monetary benefits, but also reflects its efforts to achieve greater sustainability“, says a convinced Tobias Böckle.
Environmentally friendly operation is also possible at locations where electricity cannot be supplied due to a lack of infrastructure. The electric version of Kleemann plants can also be operated autonomously with sustainable HVO diesel.
