Patent ID: 8714469

Claim:
A device for comminuting bulk charge stock, the device comprising: a housing surrounding a rotational axis with a first front wall, a second front wall plane parallel at an axial distance, and a shell wall connecting the first front wall and second front wall on a circumferential side, which together form a comminuting chamber; a material inlet to which the charge stock is fed; a material discharge via which the charge stock removed; and a comminuting system rotating about the rotational axis arranged in the comminuting chamber, the comminuting system comprising: first comminuting tools; second comminuting tools interacting with the first comminuting tools, and which form a concentric comminuting zone in which the charge stock is comminuted; and a cooling channel that is configured to be acted on with a cooling gas stream via an entry opening that surrounds the shell wall in a plane of the comminuting chamber and radially outside thereof at least in part, wherein the shell wall has at least one shell wall opening via which a partial cooling gas stream branched off from the cooling gas stream is configured to be fed from the cooling channel into the comminuting chamber.
