Abstract

A pelletizer, preferably in the form of an underwater pelletizer, having a cutter and/or grinding head and a tool carrier is provided. The tool carrier can rotatably be driven about a tool carrier axis of rotation, and at least one cutting and/or grinding tool, which is attached to the tool carrier and is spaced from the tool carrier axis of rotation, is used to knock off plastic melt emerging from a pelletizer die plate and/or for grinding the pelletizer die plate. In one embodiment, the cutting and/or grinding tool rotates together with the tool carrier about its tool carrier axis of rotation, and in another embodiment, the cutting and/or grinding tool can rotate about its own axis of rotation relative to the tool carrier.
