Comminuting apparatus with cooling device and method of operating the same

A comminuting apparatus to carry out a comminuting process, the apparatus comprising:

• a comminuting rotor mounted to a machine frame and which has a plurality of comminuting tools at a periphery,
• wherein the comminuting rotor is arranged in a comminuting chamber to receive comminution material, and is adapted to comminute the material in the comminuting chamber,
• a cooling device to introduce a liquid coolant having at least 80% water by weight into the comminuting chamber,
• a control device to control the cooling device to set a rate of introduction of the coolant into the comminuting chamber, and
• wherein the control device is configured to adapt a rate of introduction of the liquid water-based coolant into the comminuting process to an operating parameter of the apparatus, that is dependent on a quantitative throughput of the comminution material, in particular a volume throughput, a mass throughput of the comminution material, and/or a drive power of a rotor drive such that more than 60% a cooling capacity introduced into the comminution material is provided by latent heat of the liquid water-based coolant.

A method of cooling comminution material in a comminuting apparatus to carry out a comminuting process, comprising:

• disposing a comminution material in a comminuting chamber of the comminuting apparatus,
• comminuting the comminution material with comminuting tools mounted at a periphery of a comminuting rotor,
• during comminuting of the comminution material, introducing a liquid coolant having at least 80% water into the comminuting chamber, and
• adapting a rate of introduction of the liquid water-based coolant into the comminuting process to an operating parameter of the apparatus, that is dependent on a quantitative throughput of the comminution material, in particular a volume throughput, a mass throughput of the comminution material, and/or a drive power of a rotor drive such that more than 60% of a cooling capacity introduced into the comminution material is provided by latent heat of the liquid water-based coolant.
