Mobile Impactor for Recycling of Track Ballast & ConcreteRichard Forster has been using mobile crushers for processing granite, track ballast and construction debris for quite some time, however those crushers were always rented from a contractor. "With our own crusher, we can process the material at any time, which increases our flexibility," says Forster. He has been looking for a mobile crusher in the 35-ton range and tested few, including the Rockster impact crusher R1100DS with screening system and CAT C9 STAGE V engine. “We wanted to get an idea of the performance and operation of the crusher. My machine operators, in particular, have to be convinced of the system, because they are supposed to work efficiently with it,” says Forster.
Accessibility, Hydraulic Drive and Easy Transport were Key Arguments for Rockster crusherRockster offered Forster the opportunity to put the R1100DS to test at the company's own recycling center.
„The large openings and good access to the engine compartment make service and maintenance easier. We also have much better experiences with hydraulic drives as is the case with Rockster's fully hydraulic drive in comparison with diesel-electric drives, where you have to expect cable breaks and which are usually more sensitive to dust or vibrations.”
Since the crusher is used on multiple locations, i.e. the recycling site and at the company's own gravel quarry or landfills, an easy transport was also an important issue. "I like the fact that we don't have to disassemble anything on the R1100DS to transport it, just fold in the screening system and drive it onto the flat-bed trailer," explains Forster.
Performance and End Product Quality of R1100DS Impactor are TopForster and his team most often produce 0/60 material for underground stabilization from broken concrete or mixed rubble. The granite gravel from the railroad is processed to 0/16 or 0/32 mm end product, which is ideal for road construction as an underfill or for land consolidation.
„Performance and material quality are really excellent, the composition of fine and coarse fraction is exactly right for our customer requirements. The attached Air Blower also works perfectly. It has the optimal suction to blow away non-aggregate materials such as polystyrene, textiles, wood parts, plastic or ytong parts. This light material is collected directly in a container, which is surrounded by a net, and can then be disposed of. So, everything is done in one step,” Richard Forster explains with satisfactionRockster sales manager Norbert Feichtinger adds: "I was immediately convinced that we could supply the most optimal system for Forster Recycling, since we use our impact crushers particularly for construction rubble and granite processing and therefore have extremely good experience.“
