<p>An arrangement for grinding mineral products and like hard materials with the aid of a rotor-agitated grinding medium, wherein rods which function to agitate the grinding medium extend straight out from the rotor surface. The arrangement is characterized in that at least that part of the rods which project outside the rotor surface have a generally circular cross-section which decreases continuously from the rotor surface, or from a point immediately outside the rotor surface. The main parts of the rods are preferably made of cemented carbide. <IMAGE></p> |
