The invention relates to the field of the acceleration of material, in particular a stream of granular or particulate material, with the aid of centrifugal force, with, in particular, the aim of causing the accelerated grains or particles to collide with an impact member at such a velocity that they are crushed, and involves at least one sliding member (2) that is pivotly attached and centrifugally locked to the rotor (1) only along the side of the sliding member that is facing the rotor such that the attachment members (8,9) are located at a position essentially below the plane (22) with on it the outer edge (12) of the centre face (5). This has the advantage that the wear material is more effectively used such that less throw-away material remains, more sliding members can be placed on the rotor, a longer operation time is achieved, attachment members are not damaged when the sliding member wears through and that replacement is easier and special securing can be avoided.
