At bauma, Keestrack will debut its new R2 impactor and C7 3-deck high-capacity classifier.
The R2, available in full electric or conventional diesel hydraulic, has been designed to complete Keestrack’s product range of impactors.
The compact R2 is easy to operate within city centres where high flexibility and mobility are essential.
For cities requiring zero emissions, Keestrack’s Zero-drive, a full electric plug-in drive version, without any combustion engine onboard, provides the ideal solution. The new impactor has a capacity up to 150 tonnes per hour.
The crusher design is similar to the award winning, yet larger R3 impactor. The hopper (3 cubic metres) with integrated vibrating feeder (3300 x 810 mm) and pre-screen (1250 x 810 mm) also has a asymmetric design to feed the material easy into the inlet (860 x 730 mm) which is equipped with a replaceable entry beam.
The newly designed rotor, with a width of 840 mm and a diameter of 920 mm, is made of Hardox steel. The rotor has the same design concept as the bigger R3, R5 and R6 to minimize wear. The rotor speed can be adjusted by a hydrostatic drive to finetune the desired grain size. The impact aprons can be serviced from the top which facilitates service maintenance.
The R2 impactor, fully equipped in closed circuit with a 1200 x 3040 mm single deck after screen, magnet separator and windsifter has a total weight under 27 tonnes and a transport length of 13 metres, making it an agile impactor. The return conveyor of the closed circuit can also swivel outside to be used as a stockpile conveyor for oversize.
As on all Keestrack equipment, maintenance has been reduced by design, using drive and return drums which are greased for life, is just one of the examples.
The diesel/hydraulic R2 version is driven by the new Tier 4 Deutz TCD 5.2 L4 engine. The R2 is also available in Zero drive version, which is full electric plug-in and has no combustion engine.
Keestrack C7 3-deck high-capacity classifier
Keestrack will also introduce the brand-new high-capacity 3-deck classifier to complete the product range for high-capacity precision screening.
The C7, with a capacity up to 600 tonnes per hour, is equipped with a triple deck screen box of 5450 x 1800 mm with interchangeable screen meshes, which can be changed quickly.
The C7 is specifically designed for accurate and high-capacity precision screening for sand and aggregates. The walkways on each side of the screen box give perfect service and maintenance access. The C7 has no support legs, resulting in quick set up times.
The C7 3-deck classifier is available in conventional diesel/hydraulic drive, but Keestrack’s research and development department already mention their plans to make it available in Zero, full electric plug-in drive, in near future. Also, the 2-deck version is foreseen to come to market soon.
