Profitable and sustainable crushing & screening
equipment at Bauma
Invest smart in Keestrack
track mobile aggregates,
recycling and mining
processing equipment
Keestrack-2nd generation: Both sons, (left to right) Frederik and Peter Hoogendoorn run the family business.
World’s biggest construction tradeshow, Bauma, is about to
open its doors from April 7th until April 13th, in Munich,
Germany. Bauma’s and Keestrack’s focus is on sustainability,
alternative drive systems and providing solutions for the
aggregates, recycling and mining industry.
Keestrack will be at booth FN 1016/9 and will launch 2
completely new machines at Bauma.
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 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 is able to
run on ecological biodiesel. The R2 is also available in ZERO
drive version, which is full electric plug-in and has no
combustion engine.
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 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 set up times.
Keestrack-R2: R2 to be revealed at Bauma
R2 impactor, in full electric ZERO, and
conventional diesel/hydraulic drive
The R2, high performing and very compact track mobile
impact crusher, has been designed to complete Keestrack’s
product range of impactors. The R2 is easy to operate within
city centres where high flexibility and mobility are essential. In
a lot of European cities there is a need for pure electric plug-
in construction equipment. With the ZERO-drive, a full electric
plug-in drive version, without any combustion engine
onboard, Keestrack provides the ideal solution. The new
impactor has a capacity up to 150 t/h.
The crusher design features are often similar to the award
winning bigger R3 impactor. The hopper (3m³) with integrated
vibrating feeder (3300 x 810mm) and pre-screen (1250 x
810mm) also has a asymmetric design to feed the material
easy into the inlet (860 x 730mm) 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,
designed to minimize wear. 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
3040mm single deck after screen, magnet separator and
windsifter has a total weight under 27t and a transport length
of 13,05m, making it a very agile impactor. The return
Keestrack-C7:
The brand-new C7 high-capacity 3-deck classifier
The C7 3-deck classifier is available in conventional
diesel/hydraulic drive, but Keestrack’s R&D 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.
P3 twin shaft shredder
Keestrack, recently added the first tracked shredder, the P3, to
its product range. This compact twin-shaft shredder is
equipped with 2 heavy duty axles that can easily be changed
