The working parts of a cone crusher (also known as a "cone breaker") are two truncated cones. One is the moving cone (inner cone), which is fixed to the main shaft, and the other is called the fixed cone (outer cone), which is part of the frame and remains stationary. The centerline O1O of the main shaft intersects with the centerline O'O of the fixed cone at point O, forming an angle β. The main shaft is suspended at the intersection point O, while its lower end is inserted into an eccentric sleeve. The sleeve rotates around O'O with an eccentric distance r, causing the moving cone to perform an eccentric rotary motion along the inner surface of the fixed cone.
