The Rockster impact crusher R1100 is now available in a number of models
The new Rockster R1100 impact crusher range, R1100S, R1100DS and R1100DE, is said to be flexible, powerful and equipped with novel features.

The R1100 series models are already equipped with many new features, such as the fully hydraulic crushing gap adjustment, the new central control unit or the new radio remote control with display. Rockster says the crushers’ most important operating parameters, such as the rotor, feeder or motor speed, can be easily adjusted. Moreover, the models’ automatic mode, a quick-start possibility for bringing the system automatically into operation mode, can now also be started by remote control. The R1100 range’s central control unit shows a schematic layout of all processes, which enables very intuitive machine handling. Not only the conveying speed can be controlled continuously, but also all parameters are separately adjustable, such as crusher speed, speed of vibration feeder, main conveyor, or fines conveyor. Additionally, the display provides the possibility to save presets for up to three different feeding materials. Rockster redesigned all its R1100 series machines and can now offer its plants both with Tier3, and with Tier 4 Final engines. The company says that experience to date with the new Tier 4 Final engines shows that the higher power (23kW) has an appreciable effect on the crushing operation. The machines start faster, a lower crusher rotation speed is necessary and each R1100 series model requires less fuel. The crushers run smoother, are quieter and the integrated AdBlue system reduces the emission of toxic nitrogen oxides into the atmosphere significantly.

The screen box and return belt for the R1100 series have also been further improved. The new screen box has been extended by 500mm and the hydraulic cylinders for lowering the screen box are said to make for easy maintenance, cleaning or exchange of meshes. The patented return belt RB95 can also be used as a stockpile conveyor with a discharge height of about four metres. Disassembly for transport is not necessary, which in turn ensures a rapid set-up time for each of the R1100 series models after unloading.
