振动放矿是强化开采中的一种新技术。1973年至1974年,我们共同试制了ZKJ振动放矿机。经在溜井初步试验,效果良好,大大减轻了工人的劳动强度,改善了作业条件,提高了出矿能力。据实测,在不同激振力的情况下,生产能力分别达到115～366(吨/时);放矿机停车准确,能做到车车满载而又不跑矿(饱水淤泥及水砂例外);放矿量也易控制,对改善崩落法采场的损失贫化指标大有俾益;同时通过合格大块矿石的能力有很大提高,卡斗、悬顶等情况大为减少,从而减少了二次破碎量,加快了放矿速度。一、振动放矿机的结构性能和主要技术特征
Vibration ore dressing is a new technology in enhanced mining. From 1973 to 1974, we jointly trialled the ZKJ vibration mining machine. After the initial trial in the chute, the effect is good, greatly reducing the labor intensity of workers, improving the working conditions and improving the ability to mine. According to the actual measurement, the production capacity reaches 115 ~ 366 (ton / hour) under different excitation force, the mine car is stopped accurately, and the car can be fully loaded without running the mine (water-saturated silt and water sand exception ); The amount of ore is also easy to control, which greatly benefits the improvement of the indicators of loss and dilution of the stope in caving. At the same time, the ability to pass large lumps of ore has greatly improved and the number of catches and suspended roofs has greatly decreased. Reduce the amount of secondary crushing speed up the speed of ore. First, the vibration of the performance of mining machine and the main technical characteristics
