Comminuting apparatus comprising a feed device with an electromotive drive device

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 is configured to receive energy for movement of the ram device in the direction towards the comminuting rotor in a first operating situation by elastic deformation for providing a pressing force on the ram device with the actuators stationary.
