Keestrack optimizes electric drive technology

Keestrack’s global reputation as specialist in mobile mineral processing, recycling and quarrying is based on the continuous optimization of its complete range of track-mounted crushers, scalpers and screeners. Today, all models are designed for maximum mobility to minimize setup times and to save transport costs. The company’s jaw, impact and cone crushers combine best-in-class feed sizes with accurately adjustable crushing characteristics, ensuring a high versatility and large capacities in recycling and aggregates production.

From vision to mission

As one of the first manufacturers Keestrack invested strongly in the development of diesel-electric drives as an alternative to traditional diesel-hydraulic concepts. Without compromising the plants’ mobility and on-site flexibility, the “e”-versions provide combined power units with on-board diesel and generators, supplying the electric drives for crushers, screens, conveyors and ancillary equipment. Most models also offer a “plug-in”- and “plug-out” option, enabling energy supply through up- or downstream machines, external gen-sets and emission-free operation, when connected to the grid.

Lowest cost by innovation

Being able to produce “green” is great, but the main driver for the development of Keestrack’s “e”-mobility are the important energy cost savings in diesel-electric operation (approx. 30 – 50 % less fuel consumption) or up to 80 % saving potentials when connected to the mains in regions with high fuel prices.

But the “e”-versions also provide important operational benefits: Electric drives on conveyors and screens reduce leak-prone hydraulic piping and oil volumes. This minimizes breakdown risks, improves operation in extreme conditions and saves maintenance costs.

In full-electric operation this also applies to all wear parts of the onboard diesel. Less engine hours means less maintenance, which has a positive impact on total cost of ownership, as well as the higher value retention.

By using high-quality steels and the weight-optimized design, Keestrack hybrids weigh less and can be transported in one piece, without dismantling. This contributes to short set-up times. The integration of all electrical system functions is controlled by the intelligent Keestrack plant control. This includes automated routines like sequential start/stop and the telematics monitoring system.

Today nearly all of the Keestrack crushers, screeners and stackers are available with diesel-hydraulic or optional diesel-electric drive. Introducing their “heavy range” of new crushers above 60 tons transport weight, Keestrack fully switched to the diesel-electric “plug-in” drive concepts, introducing new innovative features such as “drop-off” power units (diesel + generator) for dust and vibration free remote energy supply. High rated “plug-out” connections allow the most economic operation of multi stage production trains, centrally supplied by one single power unit of the biggest machine. All Keestrack hybrid plants provide intelligent machine controls monitoring the diesel-electric or “plug-in”-operation as stand-alone units or integrated production trains.
