Abstract:
1. An apparatus for comminuting material comprising: a housing for enclosing a comminuting room; a first disk; and a second disk being arranged coaxially to the first disk inside the housing, at least a portion of opposing surfaces of the disks being provided with interacting comminuting tools thereby forming a comminuting zone, wherein at least one of the disks rotates around a mutual axis to generate a relative movement of the disks, and wherein the material, which is a mixture of gaseous and solid materials, is axially fed by one of the disks to the comminuting room and radially conveyed to the comminuting zone, wherein cooling gas is channeled into the comminuting room, wherein at least one wall is arranged in a plane that is radial to the mutual axis for partitioning the comminuting room into a first chamber through which the mixture of gaseous and solid materials flows and at least one additional chamber that is solely dedicated to the flow of cooling gas, and wherein the at least one wall is formed by the first disk or the second disk and a ring wheel that is radially adjacent thereto.
