Rockster Recycler North America introduced its mobile Duplex System, a track-mounted crushing plant that allows contractors to interchange an impact crusher with a jaw crusher, and vice versa, on the same chassis. According to Rockster, this capability creates a dual-purpose machine for a wider range of recycle, demolition and aggregate-crushing applications.
The Duplex System is available in the R1100/1200 impact/jaw models and the R900/800 impact/jaw models. The system allows one crusher unit to exchange with the other crusher unit in about four to five hours using an excavator. An overnight exchange of crusher units on the plant by a maintenance crew means the plant can be on the jobsite and ready to crush by morning.
Rockster says the R1100/1200 processes between 280 and 350 tph while the R900/800 processes 120 to 240 tph.
