<p>A grinding mill for ore or granular material capable of reducing ore or granular material of large size to a smaller size in only one device comprised by a chamber or compartment of fixed cylindrical shape, provided with at least a window for feeding the material in a radial position preferably vertical and at least one window for radially releasing said material antagonistic to the feeding window, the device being provided with a mechanism which provides the material with movement inside the chamber wherein the device which provides the material with movement is a rotatory plate which generates a cavity inside the fixed chamber wherein the material is housed, the rotatory plate having preferably flats non-parallel faces, a face perpendicular to the axial axis and the other face being inclined, on the face perpendicular to the axial axis is supportively positioned the driving axis which provides the rotational movement, the plate has the rotation axial axis preferably in a horizontal way, the inclined face being in contact with the material to be ground and is provided with lifting elements which pull the material by inducing in it a rotational and translational movement in the axial direction, this axial movement makes the material to compress against a fixed or movable wall (translation and/or rotation) positioned in an antagonistic way to the inclined face, thus generating the friction, compression, impact and attrition mechanisms of the material, considerably fracturing the structure thereof and achieving its size reduction.</p> |
