Jun 23, 2015 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.

Dec 16, 2015 Impact crushers rotary or hammer mills have the capacity for high reduction ratios up to 401, but are rarely applied to hard rock mines. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers.
The impact plates are reversible to even out wear, and can easily be removed and replaced. The impact mill gives better control of product size than does the hammer mill, since there is less attrition. The product shape is more easily controlled and energy is saved by the removal of particles once they have reached the size required.
