Description of grinding rolls for ore (1) composed of: two motors (6,6'}, one mobile roller (3), one fixed roller (2), hydraulic cylinders (4) and feeding column (5|. The grinding rolls (1) being provided with a means for controlling efficiency configured for making ongoing measurements and adjustments of their components aiming at reaching the maximum efficiency of the machine. A method for obtaining maximum efficiency of grinding rolls (1) is also described, which has the following steps: (i) determining the zero GAP; (ii) determining a set point that is equal to the optimum working point of the grinding rolls; (iii) automatic handling of pressure until the set point is reached. |
