Summary:PURPOSE: An apparatus for reducing radio-active concrete waste and removing nuclide is provided to prevent the diffusion of secondary pollution by completely removing dust due to negative pressure operation. CONSTITUTION: A grinding unit(10) includes a paddle type rotational impactor(11). The impactor grinds radio-active concrete waste in order to classify the radio-active concrete waste into pastes and aggregates. A screening unit(20) receives the pastes and the aggregates through a material discharging gate(17) which is installed in the paddle type rotational impactor. The screening unit screens contaminated micro-powder and the aggregate. An exhaust gate processing unit(30) is connected with the impactor and purifies an exhaust gas including fine particles in the impactor.
