ABSTRACT:
A device for feeding cooling fluid into the inside of a shearing drum. The rotary drive of the shearing drum has at least one gear reduction mechanism contained within the hollow shearing drum. Fluid lines are led into the axial region of the shearing drum via a component which is stationary and rigidly connected to the carrier of the shearing drum. The gear reduction mechanism is arranged concentric with the axis and at least one of the fluid lines is led to at least one lateral end face where the fluid line supplies a fluid distributor which in turn distributes the fluid to various jets and fluid lines.
