Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the

Why are my Impact Crusher Blow Bars Breaking?

The customer was experiencing breakage. When we went to the site, we found that the wedges were loose, causing the bar to move up in the rotor station, causing pressure on the locating nose. This pressure lead to a break in a blow bar. A new person was in charge of the crusher and did not realize they could loosen.
