Abstract

PURPOSE: To conduct a number of measurement in a short time by a constitution wherein magnetization detecting devices are provided at three places on a belt- conveyor and thereby saturation magnetization, residual magnetization and antimagnetic force value are measured sequentially.
CONSTITUTION: On the surface of the conveyor belt 1 are provided sample-fitting holders 2 in the same intervals with those of measuring means. The measuring means are composed of magnetization-detecting coil sets 3W5, and the coil set 3 is for measuring the saturation magnetization, the set 4 is for measuring the residual magnetization and the set 5 is for measuring the antimagnetic force. The magnetization-detecting coil sets 3W5 are fixed on the upper and lower parts of vertical-vibration frames 7 on a horizontally-moving frame 6 and are vibrated by a vibration device 11. The horizontally-moving frame 6 can be moved to the right within a fixed distance at the same speed with that of the conveyor belt 1. The coils 3-5 conduct measurement while moving to the right within a fixed distance in synchronization with the sample holders 2 and then return to the original places. By such a constitution, different properties are measured respectively at the same time for three samples, whereby numerous measurement can be performed in a short time.
