Continued improvements in raw material extraction and transportation
have advanced the use of in-pit crushing. The use of mobile crushing
units close to the working face provides efficient and versatile
systems.
Roberts & Schaefer Company has combined its services in the
development and implementation of such systems with the valuable
experience and understanding of the severe conditions that exist
in the quarry or mine. The application of in-pit crushing significantly
reduces the environmental concerns caused by truck haul operations.
Such equipment was designed for the projects below:
GRANITE ROCK COMPANY

Crushing and Conveying System
Aromas, California
Granite Rock Company selected Roberts & Schaefer to design
and engineer an in-pit mobile crusher and overland conveyors to
eliminate haul trucks. For ease of maintenance, the system's major
components are off-the-shelf while Krupp built the mobile crusher.
