Patent ID: 8800900

Claim:
An ore-comminuting-device comprising: an ore feed unit for feeding ore to be comminuted; a pulveriser configured to receive ore from the ore feed unit, the pulveriser including at least two comminuting elements that form at least one comminuting space for the ore to be comminuted such that, by relative movement in the form of rotation of one or more of the comminuting elements, the ore to be comminuted is able to be pulverised, wherein one or more accelerating elements are provided on at least one of the comminuting elements, the one or more accelerating elements being arranged on an end face of the at least one of the comminuting elements and configured to accelerate and comminute the ore to be comminuted by the rotation of the one or more comminuting elements, the one or more accelerating elements including at least one protrusion and/or at least one recess configured to act on the ore to be comminuted to move the ore away from the one or more accelerating elements in such a way that parts of the ore accelerated by the one or more accelerating elements strike other parts of the are in the at least one comminuting space forming a micro-impact by means of which the ore is pulverised; an intermediate space provided between two of the at least two comminuting elements and/or in at least one of the comminuting elements through which during the rotation the pulverised ore can be conveyed away outwards from the centre of the rotation and from the comminuting elements; and an outlet unit in communication with the intermediate space through which the pulverised ore is able to be discharged; wherein at least one of the comminuting elements has a rising ramp region in a circular form for accelerating and comminuting the ore to be comminuted.
