1. A comminuting apparatus to comminute comminution stock, the comminuting apparatus comprising:
a comminuting rotor mounted rotatably to a machine frame and having comminuting tools arranged thereon,
a receiving region to receive comminution stock,
a feed device having a ram device which is moveable in a direction towards the comminuting rotor by a drive device and which is configured to feed comminution stock to the comminuting rotor,
wherein the drive device of the feed device has at least two spaced electric actuators which are controlled by a control device and which are connected at a drive output side by a transverse member,
wherein the transverse member is operatively connected to the ram device by a resilient damping device configured to store energy by elastic deformation and to apply the stored energy to the ram device in the direction towards the comminuting rotor, and
wherein the resilient damping device includes at least one elastomer body.
