One of the earliest machine-driven rock crushers was built in the 1960s. It was tricycle mounted, its jaws were too small to be effective, and it had a tendency to jam. San Dimas Technology and Development Center (SDTDC) conducted a product search, locating the Braun Instrument Corporation (BICO) electric Badger Jaw Crusher, a laboratory crusher that could crush a 6-inch rock. It is a lighter weight crusher with a hopper that shields workers from flying rock fragments. This document describes the evaluation performed by SDTDC on this rock crusher.
