Comminution apparatus for comminuting a solids-containing medium and a method for controlling a comminution apparatus

A comminution apparatus for comminuting a solids-containing medium with a variable comminution performance, the comminution apparatus comprising:

• a rotatably mounted drive shaft, which can be coupled to a drive apparatus to drive a cutting apparatus, the cutting apparatus having:
• a first cutting element, comprising at least one first cutting edge;
• and
• a second cutting element, comprising at least one second cutting edge;
• wherein the first cutting element and the second cutting element are movable relative to one another such that a relative movement of the first cutting element and of the second cutting element brings about a shearing action between the at least one first cutting edge and the at least one second cutting edge;
• and
• wherein the first cutting element is connected fixedly in terms of torque to the drive shaft and is movable on a first movement path relative to the second cutting element;
• and
• wherein the comminution apparatus is adapted for operation in a first operating mode and at least in a second operating mode different from the first operating mode to comminute the solids-containing medium, wherein the comminution apparatus can be set between the first operating mode and the at least second operating mode by means of a control apparatus to comminute the solids-containing medium.

• wherein the first cutting element and the second cutting element are movable relative to one another in such a way that the relative movement brings about a shearing action between the at least one first cutting edge and the at least one second cutting edge;
• and
• wherein the at least first cutting element is connected fixedly in terms of torque to the drive shaft and is movable on a first movement path relative to the second cutting element;
• and
• wherein the at least first cutting element and the second cutting element are movable in translation relative to one another on a second movement path;
• wherein a detection apparatus is provided and designed to measure a contact pressure of the first cutting element against the second cutting element and/or to detect an arrangement of the first cutting element and the second cutting element relative to one another;
• and
• wherein an adjusting apparatus is provided and designed to displace the first cutting element and the second cutting element relative to one another on a second movement path to set the distance between cutting edges, until a desired contact pressure and/or distance between the first cutting element and the second cutting element is set.

• and
• wherein the at least first cutting element is connected fixedly in terms of torque to the drive shaft and is movable on a first movement path relative to the second cutting element;
• and
• wherein the cutting apparatus is disposed within a comminution hollow chamber between an opening outlet, through which the comminuted solids-containing medium can flow out of the comminution hollow chamber, and an opening inlet, through which the solids-containing medium that is to be comminuted can flow into the comminution hollow chamber;
• wherein the comminution apparatus has a sealing arrangement comprising a sealing fluid pump apparatus, which has a pump inlet and a pump outlet, and a sealing chamber which is connected to the pump outlet, is adjacent to the comminution hollow chamber, has a fluid pressure applied to it via the pump outlet, which fluid pressure results from the fluid pressure difference generated by the sealing fluid pump apparatus, and by means of this fluid pressure seals off the comminution hollow chamber against the egress of solids-containing medium from the comminution hollow chamber along the drive shaft.
