vertical-shaft impactor

A secondary or tertiary crusher consisting of a rotor or impeller disc mounted on a vertical shaft which is rotated at high speed. Rock is fed on to the centre of the rotor from where it is thrown with high radial velocity to be broken on contact with either the anvils or previously crushed rocks which line the crushing chamber.
