Static
pulverizers
Developed for
secondary demolition
The Demarec Pulverisers have been developed for secondary demolition – breaking concrete and freeing reinforced steel bars. Pulverising at the demolition site reduces the costs of transport and recycling. The Extreme version of the DSP-series is equipped with the “well known” DemaPower-System! A unique cylinder technique: 20% more power and extremely fast cycle times. The upper jaw has a ground tooth plate that has one front tooth which ensure outstanding penetration into the concrete. Both teeth in the upper jaw are between the shrouds in the lower jaw, so the reinforced steel is always optimally separated from the concrete.
Wear parts
can be changed on site
All wear parts can be changed on site. No need to transport the pulverizer to the workshop. Demarec pulverisers are supplied without cutting blades as standard. This means that the reinforcing steel can be optimally separated from the concrete without small pieces of steel being cut off. Also available in rotating version (DSP-R)
