Abstract
The crushing and classifying device of the present disclosure includes a crushing chamber into which an electrode material is inserted, a rotating shaft, a striking body, and a screen. The rotating shaft is disposed in the crushing chamber and rotates under a driving force. The striking body has a rod shape or a chain shape, and is rotatably connected at one end to the rotating shaft, and rotates in the crushing chamber by receiving a centrifugal force associated with the rotating of the rotating shaft. The screen is provided on a wall surface of the crushing chamber, and classifies the crushed electrode material. The striking body includes, at least at its distal end, an edge portion rounded to have a radius of curvature greater than or equal to 1 mm and less than or equal to 9 mm. The screen has an opening that is equal to or less than 5 mm.
