Abstract

The impact mill for crushing stone, for gravel and sand, has a motor driven rotor (5) with a steped conical surface (18) onto which the stones fall through an overhead chute (17), the rotor carrying a set of impact arms (6), all inside a chamber (19) between the arms and vertical sets of breaker blocks (8, 9, 19 etc.) supported on casings (11) which are mounted on hinges so that they can be swung open for access to the interior. Each breaker block is mounted on a support incorporating a resilient pad and a srping with an adjusting screw through the middle so that it can be shifted inwards horizontally using an external handle, so that the blocks can be staggered vertically or arranged so as to vary the shape and size of the crushing region (19).
