The crushability serves above all to determine the dimensions of the crusher and is only of secondary importance for the selection of the crusher type. The following tests and criteria give indications of the crushability: compressive strength/ Mohs hardness, “Bond impact crushing test” (2) and the “Los Angles Abrasion Test” (3).
