Abstract

Improvements in the grinding devices for hard materials in roller mills, characterized by a doser making the uniform feeding of the material to be treated precisely along the established separation between the rollers, whose doser is arranged above the discharge device, establishing this in turn at a convenient height to ensure the necessary acceleration of the material, in its path between said dispenser and the inlet slit, and to achieve a fall speed equivalent to the circumferential speed of the rollers that rotate at 1500 rpm powered by a motor, either directly or by a gear.
