The ratio of reduction varies for different sizes, ranging from about 5 to 8 and averaging about 6.5 for sizes from 8″ to 42″ inclusive. These ratios are based upon the use of standard-throw eccentrics. Usually the primary crusher is selected on the basis of size of receiving opening and capacity.

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.
