Cone Crusher’s Development History The first cone crusher was invented by the Symons brothers to improve secondary and tertiary crushing applications. While jaw crushers can provide excellent primary crushing duties, new ways of crushing needed to be developed for finer and more consistently sized aggregates. In 1920, the Symons brothers finally created the first cone crusher in the world. It crushed rocks by squeezing material between a gyrating cone and a fixed outer concave liner. The crushing process happened when large feed entered the top of the crusher and became wedged between the cone and concave liner. It was crushed into smaller pieces and fell to a lower position, where the process repeated itself. This continued until the aggregate was small enough to fall down from the bottom of the cone crusher.
