• Rockster North America Inc., 551 Anderson Avenue, Hammonton, NJ 08037, USA


The DUPLEX-able impactor of the R1100-crusher range of Rockster, the impact crusher R1100DS is already successfully established on the market and ensures best final grain.

The Rockster Impact crusher guarantees highest performance at a very high crushing ratio. Due to 2 hydraulically adjustable swing-beams, as well as variation of the rotor speed, the final grain can be optimally influenced.
The quality of the hammers is chosen individually, depending on the application and can be used bilaterally. High quality wear materials ensure reduced wear.

The Highlights:

  • Continuous, fully hydraulic gap adjustment (electronic control on display)
  • Automatic, continuous control of the conveying velocity
  • Feeder adjustment by remote control
  • Unique double-functional return belt system
  • „DUPLEX-able“: interchange of impact crusher with jaw crusher possible

Patented DUPLEX system

One machine – unlimited possibilities!

The crusher units are especially designed to transform a jaw (R1200D) into an impact crusher (R1100DS) and vice versa in only a few hours.
Therefore the plant can be optimized to the different requirements of the feeding material and guarantees a versatile operation.
