The proposal is for a separating blade for the material-removing machining of a mineral-containing hard material, wherein the separating blade is designed to be set in rotation by means of a drivable flange arrangement, and wherein a liquid coolant can be supplied to the separating blade for a machining mode. According to the invention, in an inner volume of the separating blade that is surrounded by parts of the separating blade, an inner structure for providing a flow path, through which the coolant can flow, between an inlet point and an outlet point is formed in such a way that, in the connected state with the flange arrangement, an outflow of portions of the supplied coolant from the inner volume is prevented along the flow path during the machining mode of the separating blade, thus ensuring that no coolant reaches the machining section on the outside of the separating blade.
A separating blade for the material-removing machining of a mineral-containing hard material, comprising a machining section positioned radially on the outside with respect to a central separating blade axis, for material removal of the hard material, wherein the separating blade is designed to be set in rotation by a drivable flange arrangement, and wherein a liquid coolant can be supplied to the separating blade during machining, wherein, in an inner volume of the separating blade that is surrounded by parts of the separating blade, an inner structure is formed for providing a flow path, through which the coolant can flow, between an inlet point of the separating blade for supplying the coolant and an outlet point of the separating blade for the discharge of the coolant, wherein in the connected state with the flange arrangement, an outflow of portions of the supplied coolant from the inner volume is prevented along the flow path during machining using the separating blade to ensure that no coolant reaches the machining section on the outside of the separating blade.
