According to different models of the ultrasonic thickness gauge, the distance between the ultrasonic thickness gauge and the material conveying surface of the main belt 3 is 0.25-1m, so that the ultrasonic thickness gauge can conveniently detect the material thickness value of the main belt 3. The conveying speed of the main belt 3 is 1-3m/s, the ultrasonic thickness meter collects the thickness value of the material conveyed by the second belt 2 on the main belt 3, and the weight of the material conveyed to the main belt 3 by the second belt 2 is measured according to the bulk density of the material. Wherein, the thickness value of the material conveyed to the main belt 3 by the second belt 2 is 0-80mm, so as to avoid the material from being too heavy to influence the normal operation of the main belt 3.
The utility model discloses an ultrasonic thickness gauge detects the ore feeding volume of second belt 2, the difference of rethread belt weigher and 2 ore feeding volumes of second belt detects the ore feeding volume of first belt 1, can detect out the ore feeding volume of first belt 1 and second belt 2, thereby in time discover whether first belt 1 and second belt 2 exist the problem of ore feeding volume imbalance, whether there is the problem of first belt 1 or 2 broken ore of second belt, for stabilizing the ore feeding, improve the preselection effect of magnetic drum and stabilize the performance of ball mill ore grinding efficiency and provide the guarantee.
