A device for processing feedstock is provided that includes a rotor rotating around an axis in a housing, which houses processing tools, and has stator tools that are stationary with respect to the housing, which, by maintaining a working clearance, the rotor side processing tools are arranged opposite to the stator tools and interact with the stator tools to process the feedstock. The device also includes a resetting device for displacing the stator tools in a radial direction to set the working clearance. The resetting device for the stator tools include at least one tilted support surface, which directly or indirectly forms a contact surface for the stator tools. Whereby, the support surface is slideable with respect to the stator tools in order to adjust the working clearance.
