Jaw Crushers

Jaw crushers are typically 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 moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

 Jaw crushers should be fed a consistent rate of feed that will result in the crushing chamber being kept full at all times.  This will result in more stone-on-stone crushing, reducing the wear on the manganese Jaw, creating a more cubical product, and result in more even wear over the length of the jaw.
