Impact Crusher Parts
The main components of the Impact crusher are the rotor, rotor shaft, frames, blow bars and breaker plates. The selection of the liner type and material for Impact crushers is fundamental to ensure its
desired performance. Choices for material are manganese steel, martensitic steel and white chromium iron. Also a metal matrix composite products is a new choice to the selection and their importance is remarkable.

The proportion of wear per elements corresponds more or less to contribution of each of them to the crushing action. Therefore the wear is the most important on blow bars because the most reduction work takes place when the particle are struck by the blow bars.
