Differences Between Hammer Crusher And Impact Crusher

Impact crusher can be used to crush both of the soft material and the very large hardness material. When the rotor moves, the plate hammer which is fixed to the rotor and designed to adopt the mechanical firm structure can get more force from the rotator. Compared with the hammer crusher, the rotor of impact crusher is more suitable to crush

Impact Crusher Working Principle

Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping

5 Aggregate Production IN.gov

IMPACT CRUSHING Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.
