bauma, the world’s biggest construction, quarrying, mining and recycling equipment tradeshow, is about to open its doors (7-13 April 2025) in Munich, Germany.
Like the exhibition, Belgian crushing and screening plant manufacturer Keestrack focuses on sustainability, alternative drive systems, and providing solutions for the aggregates, recycling, and mining industry.
Keestrack will be at booth FN 1016/9, launching two completely new machines.
The R2 high-performing and very compact track mobile impact crusher completes Keestrack’s product range of impactors. The R2 is easy to operate within city centres where high flexibility and mobility are essential. In many European cities, there is a need for pure electric plug-in construction equipment. With the ZERO-drive, a fully electric plug-in drive version without any combustion engine onboard, Keestrack provides the ideal solution. The new impactor has a capacity of up to 150 t/h.
The crusher’s design features are often similar to those of the award-winning bigger R3 impactor. The hopper (3m³) with integrated vibrating feeder (3300 x 810mm) and pre-screen (1250 x 810mm) also has an asymmetric design to feed the material easily into the inlet (860 x 730mm), which is equipped with a replaceable entry beam.
The R2 impactor’s 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, designed to minimize wear. A hydrostatic drive can adjust the rotor speed to fine-tune the desired grain size. The impact aprons can be serviced from the top, which facilitates service maintenance.
Fully equipped in a closed circuit with a 1200 x 3040mm single deck after screen, magnet separator, and wind sifter, the R2 has a total weight under 27t and a transport length of 13,05m, making it a very agile impactor. The return conveyor of the closed circuit can also swivel outside to be used as a stockpile conveyor for oversize.
As with all Keestrack equipment, the R2’s maintenance has been reduced by design. One example is using greased drive and return drums for life. The diesel/hydraulic R2 version is driven by the new DEUTZ TCD 5.2 L4 engine, which is very efficient, powerful, and clean. It applies to all EU Stage V and US EPA Tier 4 and can run on ecological biodiesel. The R2 is also available in a ZERO drive version, which is a full electric plug-in and has no combustion engine.
Keestrack will also introduce a brand-new high-capacity 3-deck classifier to complete the product range for high-capacity precision screening. The C7, with a capacity of up to 600 t/h, is equipped with a triple deck screen box of 5450 x 1800mm 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 setup times.
The C7 3-deck classifier is available with a conventional diesel/hydraulic drive, but Keestrack’s R&D department already mentioned plans to make it available with ZERO, a fully electric plug-in drive, soon. Also, the 2-deck version is foreseen to come to market soon.
Keestrack recently added the first tracked shredder, the P3, to its product range. This compact twin-shaft shredder has two heavy-duty axles that can easily be changed within an hour. The shredder can be used in different setups for various applications, such as construction waste, mineral waste, biomass, green waste, logs and roots, wood waste, industrial and household waste, plastics, light metal waste, tyres, etc.
The 14.5t Keestrack P3 tracked mobile shredder features a tillable loading platform to feed the shredder. The shredder has a feed opening of 1589 x 1200 mm and a shaft diameter of 700 mm. The torque of 90,000 Nm per shaft provides a massive power of 180,000 Nm. The shaft speeds are 45 and 25 rpm, and the rotation varies according to the program selected. The shredder features an automatic release system that reverses the direction of rotation.
The P3 has options such as a magnetic separator to separate precious metals, a remote control, an afterscreen, working lights, and a fuel pump.
As expected, the P3 provides easy access for service, maintenance, and repairs. The engine compartment is very accessible, with the new, very efficient, powerful, and clean DEUTZ TCD 5.2 L4 engine. It applies to all EU Stage V and US EPA Tier 4 and can run on ecological biodiesel.
Also on show at bauma 2025, Keestrack’s B5, available in 3-drive versions: conventional diesel/hydraulic, hybrid plug-in and ZERO full electric-drive, is a compact, heavy-duty jaw crusher used for primary crushing in quarrying and mining applications. The hopper (5m³), with heavy-duty folding hopper walls with a hydraulic locking system, is easy to load by excavator and wheel loader. The vibrating feeder (2300 x 1000mm) automatically adjusts the feeding material to the crusher to ensure the load capacity of the jaw crusher is optimal (80%). The long independent 2-deck pre-screen (2300 x 1000mm) ensures a high crushing capacity while reducing the crusher’s wear. The pre-screened fraction(s) can go through the crusher bypass or be separately stockpiled by the optional side conveyor.
The jaw crusher has a feed opening of 1110 x 750mm and a feed size of up to 600mm. The stroke of the swing jaw can be adjusted for hard stone or recycling applications. The jaw movement is reversed to remove blockages.
The B5’s Closed Side Setting (C.S.S.) ranges from 45 to 180mm, even on worn jaws. The hydraulic gap settings can be changed via a wedge system. During operation, the automatic wear recovery is active every 50 working hours, guaranteeing the consistent quality of your end product. The wear recovery can also be set manually if needed.
The B5’s design facilitates maintenance and repairs through accessible walkways, doors, and panels on all sides of the machine. The hydraulic sliding frame also ensures good service access under the feeder and scalping unit. The jaw crusher has 3-piece cheek plates, which make replacements easier. Replacement of the jaws is fairly simple due to the easy-accessible jaw plate top locking system.
Like many other Keestrack crushers, the B5 is equipped with a drop-off engine/gen-set compartment. The engine can be placed beside the machine in less dusty and vibrant conditions. Maintenance is much easier when the compartment is placed at ground level.
