Recycling imperfection at zero emission - Büscher

Recycling in perfection, Keestrack plug-in electric crushing and screening at Zero emission converts demolition waste to sustainable construction material.
R3e ZERO impact crusher & K4e ZERO screen
The innovative technology, its safety features and the design of the R3 impact crusher has won several European design prices, one of them being the Red Dot award. The very compact and easy to transport impact crusher available in; diesel/hydraulic drive , electric plug-in drive (with onboard backup diesel gen-set) and ZERO drive: full electric plug-in without gen-set backup, has a capacity up to 250t/h.
The Büscher company choose obviously the ZERO versions to minimize the environmental impact as it runs at zero carbon footprint, powered by their own solar energy.
The R3e ZERO is equipped with a vibrating feeder with a pre-screen of 1.200mm x 920mm to optimize crushing results and to minimize wear, an inlet opening of 770mm x 960mm (HxW) and a rotor diameter of 1.100mm and a rotor width of 920mm. The crusher equipped in closed circuit with recirculation conveyor and a precession screen of 3.100mm x 1.400mm produces a defined aggregate product size. The installed wind sifter eliminates contaminations of plastics, wood or paper and the overband magnet separates the metals. The R3e ZERO weighs 32t, and its plug-out of 125A, powers the connected K4e ZERO of 28t.
The K4e ZERO, has a high productivity with a capacity up to 350t/h. The double deck screen box of 4.200mm x 1.500mm, standard heavy duty plate apron feeder and hydraulic adjustable screen angle gives it very good screening capabilities. The numerous available options and screen decks make the K4 suitable for each job. At the recycling site of Büscher they choose to have the fine and middle fraction conveyor at the same side of the screen to improve the accessibility for the wheel loader.
Each Keestrack is designed to have good service access to minimize maintenance and repair times but at the Keestrack ZERO-range there are no engines on-board meaning maintenance is strongly reduced.
Both Keestrack machines at Büscher are equipped with remote controls to operate the crusher and screen from the excavator. They both have an integrated water spray system which can be used in case the production is too dusty. Also both are equipped with a Keestrack-er UMTS system. This telematics software system provides real-time data and analytics. The system enables you to check the location of the machines and if they are working correctly. All aspects of a machine can be checked and if necessary, remote updates to the software can be made. It is possible to run diagnostic tests for all components including the feeder, screen, crusher and conveyors. The Keestrack-er also functions well for maintenance planning by Oppermann & Fuss, helping to keep machines in optimum shape.
