Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

Many factors make laboratory jaw crushers the optimum selection for effective and efficient primary crushing of hard, brittle, rock-like materials. Laboratory models are available with sample top sizes from 1in to 8in (25mm to 203mm). …
Jaw crushers are typically used as primary crushers because they can take large and variable sized feed material, so the original feed won't have to be blasted down to a fine size. Powerscreen jaws are designed to be significantly more reliable and have lower wear rates, maximizing production and minimizing wear parts. ...
Jaw crushers are used as the primary crushers in the first stage of the crushing process. Jaw crushers are preferred for when breaking large rocks is the priority rather than achieving high capacity. Jaw crushers can be used as first-stage crushers in small- and medium-sized plants, as well as for secondary crushing when necessary. ...
® C130™ jaw crusher is commonly used as a primary crusher, preparing material feed for the secondary crusher. However, even though it is traditionally seen at the first stage of the crushing process, this crusher also performs well in other roles, depending on the processed material and application.
