    Nov 01, 2019 A toothed double-roll crusher (referred to hereafter as TDRC) consists of a pair of oppositely rotating rolls, which have a series of intermeshing teeth protruding from the roll surfaces. The crushing action of TDRC is a combination of compression and ripping, where the teeth can dig into the rock and larger pieces than the roll diameter can be

    The double wheel breakage test - ScienceDirect

    Jul 01, 2021 Knowing that the double roll crusher won’t apply extremely high or low strain rates to the particle, one may reasonably choose that a particle of hard rock can withstand 100 MPa of stress and require between 50 and 250 Joules of energy to break depending on its size. This rationale served as the basis for defining the main design criteria
