MPEX Optimizes Electric Drive Technology- From Vision to Mission

Time:2019-03-28

MPEX Corporation offers today the most versatile range of hybrid and plug-in solutions in mobile processing technology for quarrying and recycling applications. This applies to the complete product range, from screening plants and stockpile conveyors to mobile track-mounted crushing solutions of all relevant technologies and for all production capacities.

Recognize and use benefits

MPEX recognized the huge saving potentials and operational advantages of electric drives for highly flexible track-mounted mobile processing solutions.

With the plug-in option, to connect to the mains, the MPEX full electric versions further enlarged their operating cost advantage over conventional diesel-hydraulic systems. Installed electrical pumps for essential hydraulic consumers (lifting cylinders, track drive, etc.) allow the full-electric operation of today's dual power-versions. Compared to conventional diesel-hydraulic systems, energy costs can be reduced up to 80% - the noise levels during emission-free plug-in operation by about 30%. Replacing hydraulic drives on conveyors, screen shafts, compressors or water pumps by electric motors also avoid long oil piping with leak-prone hose connections. Thermal problems in operations under extreme conditions are eliminated. With significantly lower oil quantities and extended change intervals the smaller hydraulic systems of MPEX's electric-versions not only save the environment but also real money.

In full-electric operation, this also applies to lubricants, filters and other wear parts of the onboard diesel. Less engine hours mean less maintenance and downtime, which has a positive impact on total cost of ownership, as well as the higher value retention. And finally: engine problems on a diesel-hydraulic crusher can stop the whole production or job-site, with a plug-in hybrid machine, a total breakdown can be relatively easy avoided by providing an additional external gen-set to ensure the finalization of the project.

Thanks to their on-board diesels, MPEX's modern "e"-versions remain as flexible and highly mobile as conventional technology without having to add a lot of additional transport weight compared to the respective diesel-hydraulic version. By using high-quality steels and the weight-optimized design, MPEX hybrids still undercut significantly the transport weights of most diesel-hydraulic competitor models of the same capacity. Even the larger hybrid plants can be transported in one piece, without dismantling. This also contributes to short set-up times. The full integration of all electrical system functions are controlled by the intelligent MPEX plant control. This includes numerous automated routines (eg. sequential start/stop) and the comprehensive monitoring.
