Ⅰ、振动放矿机的改进我矿购进24台振动放矿机,在使用三年以来,问题不断出现,主要是电机易烧坏,最多时一台放矿机在一个月内烧坏7台电机,造成重大经济损失。经过分析,其原因是: 由于在采矿过程中的高压水渗入矿石内,导致矿石的粘性系数增大,从而引起矿石与振动槽台的摩擦系数增加。因此,每当放矿三、四个小时后许多细小的矿粒就附着在振动槽台上。这样,随着工作时间延长,就阻止了矿石向下滑动,从而导致电机烧环。 I. Improvement of vibrating ore miner I purchased 24 vibrating ore mines from mine, and the problem has appeared constantly since it was used for three years. The main problems are that the electric motor is easy to burn out, and most of the mines are burned out in a month Taiwan Motor, causing major economic losses. After analysis, the reason is that due to the infiltration of high pressure water into the ore in the mining process, the viscosity coefficient of the ore increases, causing the friction coefficient between the ore and the vibration tank to increase. Therefore, every three or four hours after the ore is mined, many fine ore particles adhere to the vibrating tank table. In this way, as working hours are extended, the ore is prevented from sliding down, causing the motor to burn the ring.
