The utility model discloses a decision maker of magnetite grade belongs to and measures technical field, and the purpose improves the accuracy of magnetite grade judged result to shorten grade judgement time, technical scheme is, including shell, measurement spring, scale plate and magnetism pointer in its constitution, the shell is equipped with the measurement mouth, measure the coil spring of spring for fixing at the shell inside, its one end is relative with the measurement mouth of shell, the scale plate is fixed on the shell and is located one side of measuring the spring, the magnetism pointer is fixed on measuring the spring and corresponding with the scale mark on the scale plate. The utility model discloses measure the grade of magnetite according to the size of mutual appeal between magnetic pointer and the magnetite, not only improved measurement of efficiency greatly, can guarantee the accuracy of grade decision result moreover, provide favorable technical guarantee for the increase of production of mine enterprise increases efficiency. |
