Abrégé

The invention regards to a device for comminuting ore and/or slag, which comprises an ore feed unit for feeding ore to be comminuted to a first comminuting means, the first comminuting means being composed of at least two comminuting elements that can be moved relative to each other, which elements form at least one comminuting space for the ore to be comminuted with each other such that, by a relative movement in the form of a rotation around the rotational axis of at least one of the two comminuting elements, the ore to be comminuted is pulverized in that one or more accelerating elements, in particular protrusions, are provided on at least one of the comminuting elements, said accelerating elements being arranged in particular on the end face of one of the two comminuting elements and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements, and wherein at least one of the two comminuting elements comprises a functional connection with a spring means, wherein the spring means is formed in such a way, that it mounts the comminuting element being in functional connection with variably in the direction of the other comminuting element.

Abrégé

The invention relates to a device (290) for comminuting ore and/or slag, comprising an ore feeding unit (1) for feeding ore which is to be comminuted to a first pulverizer (300), said first pulverizer (300) being composed of at least of two comminuting elements (30, 40) which can be moved relative to each other, said elements forming together at least one comminuting space for the ore which is to be comminuted, such that, by a relative movement in the form of a rotation about the rotational axis of at least one of the two comminuting elements (30, 40), the ore which is to be comminuted is at least partially pulverized. One or more accelerating elements (35), in particular protrusions (35), are provided on at least one of the comminuting elements (30, 40), said accelerating elements being arranged in particular on the end face of at least one of the two comminuting elements (30, 40) and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements (30, 40). An intermediate space (60) is provided between the two comminuting elements (30, 40) and/or in at least one of the two comminuting elements (30, 40), through which space the pulverized ore, during the rotation, is transported from the center of rotation toward the outside and away from the two comminuting elements (30, 40). At least one of the two comminuting elements (30, 40) is operatively connected to a hydraulic spring pressure device (604), said hydraulic spring pressure device (604) being designed such that the comminuting element (30, 40) to which it is operatively connected is variably resiliently mounted in the direction of the other comminuting element (30, 40) depending on an adjustable hydraulic spring pressure control unit.

The claimed invention also comprises an outlet device (14) for discharging the pulverized ore through the first pulverizer which is connected to the intermediate space (60). The outlet device is connected to a separating device (413) through which the pulversied ore can be distributed in two parts, the first part of the pulverised ore having a particle size which is essentially larger than a predetermined particle size of the second part of the pulverised ore, the first part of the pulverzised ore being guided to the first pulverizer or to the second pulverizer and the second part of the pulverzised ore is guided to a flotation device.
