The present invention relates to an installation for preliminary crushing of articles, the installation comprising at least a first shaft (14) for driving articles and a second shaft (12) for shredding driven articles, each of said shafts being provided with shredding teeth (16) and each being rotated by at least one motor (7, 8), a gearbox (3, 4) for reducing the speed of each motor (7, 8) being placed between each motor and the associated shaft (12, 14), the installation further comprising both means for controlling said motors in association with sensors for picking up operating parameters of the installation, and data acquisition and processor means (100). According to the invention, the installation further comprises a universal joint (3a, 4a) disposed between the outlet shaft of each motor (7, 8) and the inlet shaft of each gearbox (3, 4), and in that each gearbox is mounted to stand on shock absorber means (15, 17), thus enabling the energy created by impacts and/or torques above a given threshold at the teeth (16) to be absorbed.
