尖山公司选矿厂的皮带漏矿车利用ＰＬＣ控制，实现了自动 定点卸料的功能。这种控制方式是根据车位开关和料仓料位信号来决定行走和卸不卸料。车位开关与料位计信号的准确性很重要。 原车位开关采用 ＣＫ－９１型磁感应位置检测开关，它动作的原理是，漏矿车边缘多焊出一块角铁 Jianshan company beneficiation belt leaking mine car using PLC control, automatic fixed point unloading function. This control is based on the parking switch and silo level signal to determine the walking and unloading unloading. The accuracy of parking switch and level gauge signal is very important. The original car switch using CK-91-type magnetic sensor position detection switch, the principle of its action is, the edge of the mine car leakage welding a piece of angle iron
