摘要

Improvements in the mills of fine mechanical crushing of solid substances, in which the material to be crushed is centrifuged and its kinetic energy is used for the impact against a fixed shield in order to obtain the crushing of that, characterized in that the mill is constituted by a metallic frame in which the following essential parts are applied: a loading hopper of the material to be crushed, coaxial with the rotor arranged below it; a centrifugal rotor of vertical axis constituted by an empty cube fed by the hopper disposed above, and communicating with radially arranged channels within which the material to be crushed is centrifuged; a series of disintegrating hammers applied to the periphery of the rotor in correspondence with dividing sectors interposed between the channels; an annular shield that coaxially surrounds the rotor, to form a grinding chamber, closed by the upper part and communicating by the lower one with the hopper, disposed below, of discharge of the treated material, and which has the peculiarity of being able to slide axially to the rotor, to position your work surface at will; an engine linked to the rotor, by an elastic transmission, and which has the possibility of inverting the direction of its movement at will.
