在有色金属浮选选矿过程中,给药控制是其中的一个重要环节,它直接影响选矿的效益和选矿的经济技术指标。单板机控制电磁阀的给药机在给药精度方面具有很大的优越性,而且配用微型打印机可以打印出流量和药耗量等信息。它的最大缺点是在电源停电和有异常干扰信号时,容易造成数据存储器清零,因而无法实现药耗量计算;另外,单板机自身抗干扰能力极差,其故障率相对来说比较高。这些缺点使得它的应用受到很大限制。以下介绍黄沙坪
In non-ferrous metal flotation beneficiation process, drug delivery control is an important part of it, it directly affects the beneficiation of beneficiation and economic and technical indicators of beneficiation. Slot machine control valve to the delivery of drugs in the administration of precision has great advantages, but with a mini printer can print out traffic and drug consumption and other information. Its biggest drawback is that in the power outage and abnormal interference signals, easy to cause data memory cleared, which can not be achieved drug consumption calculation; In addition, the board machine itself very poor anti-interference ability, the failure rate is relatively high . These shortcomings make its application is greatly restricted. The following describes Huang Shaping
