Experimental study of crushing process of the crushed stone
centrifugal impact crushers have one accelerator and work on the principle of "stone on stone" with a vertical shaft. Such crushers were first used by Barmac Associates (New Zealand) in the 70s. XX century [11]. In most tasks, the crushing and grinding equipment uses the principle of destroying the stone-to-stone material.

Forces in a Cone Crusher | Steel in Translation
The crusher will be most effective when the mobile cone rotates around its axis. In that case, force Fro acts on the piece, creating an internal torque. Such behavior is feasible within a cone crusher with parallel axes of the crusher and the mobile cone, if the mobile cone is rigidly attached to its shaft.
