The invention provides a dual-rotor counter-impacting type vertical shaft crusher. The dual-rotor counter-impacting type vertical shaft crusher comprises a rack, bases, directional stone casting rotors, motors, triangle belts, a crushing cavity, a crushing cavity wall, lining boards, a feeding port, a discharging port and an air hose. The dual rotors are used for casting materials, so that the materials are crushed by impacting each other. As the counter-impacting effect is better than the unidirectional impacting crushing effect, each crusher is provided with the two directional stone casting rotors for mutually casting the materials, so that the materials are crushed by impacting.
